March 21-26, 1913: A Period of Historic Weather In Our Area

March 27th, 2015 at 11:23 pm by under Chad's WLFI Weather Blog

VIOLENT SEVERE WEATHER OUTBREAK WITH HEAVY RAIN TO UNSEASONABLE SNOWFALL TO WORST RIVER FLOODING ON RECORD……………ALL IN A WEEK IN MARCH 1913………

March 21-26, 1913 was an amazing period of weather in our area.  From near-record cold to warm April-like weather, a significant severe weather outbreak (violent likely EF4tornado nearby at Terre Haute killed over 20 people on the south side of town) to massive flash floods, then river floods with 2-8″ of snow in-between.

For example, Rensselaer went from 6 degrees on the morning of March 17th to three days in the 60s, including 68 on the 19th & 67 on the 20th.  This was followed by our severe weather outbreak, then temperature dropped to 10 degrees.  After 50s March 25 with heavy rainfall, 2″ of snow was measured on the morning of March 25.  On March 27 the high/low was 31/20 with 55 on March 29.  A total of 4.74″ of rain/melted precipitation occurred March 21-26.

Up to 8″ of rainfall occurred in our southern counties during this period.  Up to 11″ fell in eastern Indiana, leading to the infamous great Flood of 1913.

It was a week of weather to remember!

I am working on a complete write-up, complete with graphics, on that event & what caused the historical events of that time.

19131913219131

March 19, 1913

Strengthening surface low began to accelerate northeastward out of Colorado on the morning of March 19, 1913 with strong southerly breezes out a ahead of it.  Meanwhile, Arctic air began roaring southward into the Dakotas.  Little rainfall was evident in the Plains, however (snow in the Rockies) as of 8 a.m.

It appears at that point, potent upper jet streak was moving into Colorado, which would eventually strengthen surface low rapidly.

Temperatures were mild in the mid 40s here with strengthening south to south-southeast winds amidst mainly clear skies at 8 a.m.  Low temperatures the morning before were in the teens.

 

March 20, 1913

Strong surface low was pivoting through upper Michigan on the morning of March 20, 1913 with a round of rain & some t’storms.  There were no reports of severe weather in our area, however.  Despite seemingly potent mid & upper jet & intense chunk of cold air to our northwest, temperatures near 52 degrees kept instability low.  Strong south to southwest winds were found with the rain.  After the front went through, temperatures dropped in the afternoon.

Another surface low was developing in Colorado with, apparently, a very strong upper jet was nosing into the Rockies.  I say that, because this surface low really blew up & deepened tremendously late in the day on March 20.

A severe weather outbreak of wind, large hail & tornadoes occurred with this system in Nebraska, Kansas, Oklahoma & Missouri.  A violent tornado of likely EF4 strength slammed into Omaha, Nebraska, resulting in significant damage & fatalities.  Several other violent, EF4-EF5 tornadoes struck Iowa & northern Missouri.

 

March 21, 1913

Deep surface low pivoted through with surface low tracking from Danville, Illinois to South Bend with the upper low likely in southern Wisconsin to central Michigan in the early morning hours of March 21.

With temperatures surging into the mid & upper 60s & strong south winds, line of severe storms (likely enhanced by strong low-level jet) rushed through the area.  Evidence points towards likely embedded bows, LEWP & perhaps supercellular features.  Widespread damage to trees, fences, signs, homes & buildings within the cities of Lafayette & West Lafayette.  There is no evidence of a tornado, but strong evidence of widespread, significant straight-line winds.  Evidence points towards a very wide swath of 60-80 mph winds with a few embedded 100 mph microburst cores.

A violent likely EF4 tornado struck the southside of Terre Haute.  Entire 2nd & 3rd stories of homes were missing in tornado damage pics of that area & there was a stretch where homes & businesses were totally gone with only foundations left.  Large trees are completely devoid of branches with bark peeled off & large 2 X 4s were driven into trees & buildings.  Splinters of wood were embedded in trees & homes.  All points to EF4 strength.  This tornado was said to be on the ground for over 50 miles with a Prairieton through Clay County (damage near Brazil) to Putnam & southwest Hendricks County.  The EF4 strength peaked at Terre Haute & was likely EF3 in Clay County, before going down to EF2 strength in Putnam/Hendricks counties.  Over 250 homes were damaged or destroyed with the Root Glass factory & Gartland foundary heavy damaged/destroyed.  17 people were killed with at least 150 people injured on the southside of Terre Haute.

Two damaging tornadoes occurred in southern Illinois, another just north of downtown Chicago & yet another slammed into the city of Paducah, Kentucky with heavy damage.

Temperature tanked from the 60s at 6-6:30 a.m. to 40-45 degrees by 7:30-8 a.m. with howling northwest winds.

 

March 22, 1913

March 22 saw an Arctic high arrive & sit on top of us with lots of sun, though it appears cirrus clouds began to overspread region through the day as strong warm front developed to our southwest & south.  The morning started in the teens with highs only around 40.

 

March 23, 1913

March 23 was a rather odd, transition day.  I say odd because in the morning, intense elevated t’storms with some small hail (& lots of freezing rain towards Chicago) were passing through with temperatures 35-38 degrees & strong southeast winds.  It was another round of pretty heavy rainfall after only about a two-day break in rain.  After teens yesterday morning in Missouri, it was as much as 40 DEGREES WARMER on the morning of March 23 with strong warm front working northward.

Showers & t’storms were with us through the day with strong southeast, then south winds & skyrocketing temperatures as strong surface low developed in eastern Colorado.

Deep moisture from the subtropics & tropics courtesy of likely active MJO pattern was bringing heavy tropical rainfall to south Texas & into the Gulf of Mexico.

 

March 24, 1913

A classic heavy rainfall set-up over the Ohio Valley & Midwest on this date.  strong low pressure pivoted through far northern Michigan, while deep, robust tropical moisture surged north.  Meanwhile upper- & mid-level winds paralleled stalling front in the Ohio Valley.  Impressive surface convergence & likely very strong rising motion from diffluent upper flow made for widespread training rain & t’storms from Missouri to Pennsylvania.  Our temperatures climbed into the 50s & lower 60s with strong southeast to south winds after temperatures around 55 at 8 a.m.

Another wave or surface low rode the front in the afternoon & night across the region, enhancing the rainfall, especially in eastern Indiana to Ohio.

 

March 25, 1913

After all of the flooding rainfall on March 24, new surface low formed in central Arkansas, while Arctic high pushed into Montana, then the Dakotas, bleeding in colder air.

At 8 a.m. on March 25, it was raining & mid 30s at Lafayette with a howling northeast wind, while Pittsburgh, Pennsylvania sat at 70 degrees.  This shows the strength of the front & how the heavy rain just trained along & just north of it like cars on a train track.  At the same time, Chicago had snow & 30, while South Bend had freezing rain & 30. Nashville, Tennessee had 72 & thunder in the northern sky, while St. Louis had rain & 39 at 8 a.m.

 

March 26, 1913

The surface low moved from central Arkansas to Pennsylvania with up to 8″ of snow in our viewing area.  The heaviest totals occurred in a band from northern Warren County to Lafayette to Logansport, Peru & Wabash to Marion.

A wintry mix with up to 4″ of snow occurred in our southern counties.

Behind this system, cold air settled in for a couple of days.  The high temperatures on March 27 only reached around 30 for most of the viewing area.  However, by March 29, the area was in the mid to upper 50s with 54 at West Lafayette, 55 at Whitestown, 58 at Crawfordsville & 55 degrees at Rensselaer.

Historic river flooding peaked at this time after the historic, heavy rainfall that climaxed to the training, torrential rains of March 24.

The highest flood crests on record (& these crests are still the highest to this day) at these locations:

Wabash River…….

Lafayette:  32.9′ (Flood Stage 11′)  March 26, 1913

Logansport:  25.3′ (Flood Stage 15′)  March 26, 1913

Covington:  35.1′ (Flood Stage 16′)  March 27, 1913

Wabash:  28.7′  (Flood Stage 14′)  March 26, 1913

Wildcat Creek………

Lafayette:  25.4′  (Flood Stage 10′)  March 28, 1913

Sugar Creek……….

Crawfordsville:  17.3′ (Flood Stage 8′)  March 27, 1913

 

 


Record Vs. Projected Lows For Early Saturday Morning

March 27th, 2015 at 4:28 pm by under Chad's WLFI Weather Blog

The scattered snow showers will taper this evening, followed by gradual clearing.

Record & projected lows for early Saturday morning:

No Need to Worry………But……….

March 27th, 2015 at 2:48 pm by under Chad's WLFI Weather Blog

No need to worry………….this cold & snow will be a distant memory come mid to late next week!

Sharp cold front may arrive around Saturday, April 4, though.

Outlook to April 14

March 26th, 2015 at 10:05 pm by under Chad's WLFI Weather Blog

This gives you of the trends being monitored over the next 2.5 weeks.

FRIDAY-FRIDAY NIGHT…………….

After 23-26 tonight with partly cloudy skies, skies will turn mostly cloudy by Friday morning with windy conditions (north to northwest gusts to 32 mph) with scattered snow showers.  Brief, local dustings are possible.

The projected high of 33 in West Lafayette would make it the 7th coldest March 27 since 1879.

Lows Friday night will drop to 12-17.  The record for West Lafayette & Veedersburg is 13 set in 1934 with 14 as the record low at Frankfort set in 1934.  Elsewhere, the temperature will not come close to the record lows owing to snow pack on March 28, 1934.

100102103

15DMA Map II

SATURDAY-SATURDAY NIGHT…………..

Saturday will still be cool at 35-41, but there will be much less wind compared to Friday.  This, with mostly sunny skies, will lead to a reasonably pleasant day with a coat on.  Winds look north at 5-10 mph.

Clouds will be on the increase Saturday night & after temperatures fall to near 25, they will begin to slowly rise after 1 a.m. to around 30 by early Sunday morning with northeast & east winds at 5-10 mph turning southeast to south at 10 mph.

107108

SUNDAY-SUNDAY NIGHT…………..

With mostly cloudy to cloudy skies Sunday, winds will be strong ahead of a surface cold front, gusting from the south & southwest to 32 mph with sustained winds around 22 mph.

A wave of scattered showers is likely in the afternoon to evening with highs at 47-54.  Rainfall amounts look light at 0.02-0.13″.

With front through, winds westerly at 10-15 mph, lows of 33-37 seem good for Sunday night-early Monday morning.

103111

MONDAY-MONDAY NIGHT………….

As for Monday, wind will turn westerly to southwesterly pretty rapidly, so we will actually be warmer than Sunday with the sunshine.

It will be a windy day with gusty west to west-southwest to southwest winds at 20-35 mph with highs at 55-60 & 36-42 Monday night (with southwest winds diminishing & turning east-southeast to southeast at 5-10 mph).  Some areas of high & mid clouds may pass as warm front lifts northward toward & into the area.

1113

TUESDAY-TUESDAY NIGHT……………..

With northward migration of the surface warm front Tuesday, strong southerly to southwesterly winds will usher in highs of 65-70 with partly cloudy skies.  Tuesday night, lows of 47-54 are likely with southeasterly winds at 10-15 mph & partly cloudy skies.

2114

WEDNESDAY-WEDNESDAY NIGHT…………..

Wednesday will be windy with gusty south to southwest winds at 20-35 mph with highs of 69-74 with partly to mostly cloudy skies.  If we can make it a mostly sunny day, it could go warmer than this.

A couple spotty showers are possible in the afternoon-evening.  Severe weather threat may develop from southern Iowa to Oklahoma.

Wednesday night looks quite mild with strong south to southwest winds at 25-40 mph with temperatures hanging around 60-65 most of the night until the band of showers passes (few t’showers possible) late Wednesday night-Thursday morning which will occur with passage of surface cold front.  This front will cool the area to 47-54 by early Thursday morning.

There is only enough elevated CAPE likely available for lightning/thunder discharge & nothing more, it appears right now.

4116117 119

121

THURSDAY-THURSDAY NIGHT…………..

Once the showers exit, a dry, gusty west to west-northwest wind will shunt the cold east & not really cool us off much.  Much of the low stratus/stratocumulus around the surface low will be shunted east, but it may get hung up in our northeast.  This would keep our northeast mostly cloudy Thursday & thus cooler than the rest of the area.

Regardless, the winds may gust to 30 mph with sustained winds at 10-20 mph.  Highs of 58 to 67 are likely with lows of 37-46 Thursday night with west winds around 10 mph.

Even Friday, conditions will remain breezy with highs of 59-65 area-wide with partly cloudy skies.

122125102103

APRIL 4-5………

It should stay warm/mild early next week to around Saturday April 4, it appears.

A stronger surface cold front may approach April 4 as pretty strong Arctic high builds southward over Manitoba.  West of this high, a big upper ridge in the west will make a deep trough in the east.

This spells a brief, but decent cold snap.

Saturday, April 4 is the best estimated of timing for the front with temperatures cooling to the 40s after highs at 58-66.  Lows of 28-32 are likely Saturday night-Sunday morning (April 5).

Highs on Sunday, April 5, may only run 44-49, based on the latest analysis.

1245110

APRIL 6-9…………..

April 6-8 pattern favors a rather cool, northwest flow regime with a weak clipper or two with breezy-windy conditions & a few rain/snow showers.  Lows may drop to the 20s (perhaps a 20- to 25-degree night)

APRIL 10-14…………

My thinking is that cool pattern will flip-flop to a warm pattern with 70s & 80 after April 8.

 

 


Rain/Snow/Sleet Long Gone, But Some More Sct’d Snow Showers Friday……Near Record Cold

March 26th, 2015 at 2:26 pm by under Chad's WLFI Weather Blog

The rain/snow/sleet from this morning is long-gone & we are getting some slow clearing with temperatures in the upper 30s to lower 40s.

Only trace amounts of snow/sleet occurred.

Anywhere from 0.50 to 1.40″ of rainfall occurred over the past two days, per reports viewed & received.

15

With partly cloudy skies, lows tonight will drop well down into the 20s.

12

With skies becoming mostly cloudy Friday, some scattered snow showers are possible.  Northwest to north-northwest winds will be strong at 20-30 mph.  With the wind & highs at only 30-36, wind chills will stay in the teens most of the day.

The record low high temperature for March 27 at West Lafayette is 21 set in 1955.  The record low temperature for March 28 is 13 set in 1934.

In showing how one year can vary greatly from the next, the high on March 27, 1894 was 35 with a low of 14.  Just a year later, March 27, 1895, the high was 76!

The forecast high of 33 Friday would make it the 7th coldest 27th since 1879 & the Saturday morning low of 15 would fall 2 degrees shy of the 1934 record.

DMA Map II15

Near record cold is possible for our central & southwestern counties Saturday morning.  Lows area wide may run 13-17.

Saturday will feature sun & much less wind with highs at 35-41.

Some Wet Snow In the Morning

March 25th, 2015 at 10:26 pm by under Chad's WLFI Weather Blog

NW Chicago Metro quake this evening:  http://earthquake.usgs.gov/earthquakes/eventpage/us10001qrx#general_summary

_________________________________________________________________________________________________________________________________

It has been an active evening from southern Illinois to Oklahoma.  Several tornadoes have been reported with hail up to softball size & wind gust to 80 mph.  Sadly, one person was killed & several injured by a tornado near Tulsa, Oklahoma.  Much more typical to see this weather now, than the extreme quiet severe weather regime of late.

Warnings issued so far this evening (as of 10:30 p.m.):

101

Still looks rain with a couple of t’storms tonight.  This rain may end as some snow tomorrow morning.  Grass & car tops may be whitened as temperatures fall to 33-35.

Some partial clearing is possible in the afternoon-evening with a gusty northwest wind at 15-30 mph.  Highs of 37-42 seem reasonable.


F5/EF5 Tornado List For U.S.

March 25th, 2015 at 10:04 pm by under Chad's WLFI Weather Blog

Violent EF5 tornadoes that obsolutely obliterate everything in their path are not new in their occurrence.  History has shown that this massive, violent twisters have been occurring with no uptick or downturn in trends (decade by decade) since the earliest records & reports have commenced in the United States.

Here is a list of those F5/EF5 twisters.  The 1952-current data comes from SPC.  Prior data is personal research per damage reports (with study of width & track length, as well) & classification by the National Weather Service.

NOTE:  The March 20, 1866 tornado in Montgomery County was possibly a high-end EF4, but it currently does not appear to have been an EF5.  The long-track May 1917 tornado in Indiana has been arguably classified as an EF5 by some, but it was definitely high-end EF4.

The March 1913 Terre Haute tornado was likely a solid EF4, per photos & damage descriptions.

Some Snow?

March 25th, 2015 at 4:21 pm by under Chad's WLFI Weather Blog

It is pushing 80 in parts of the Louisville, KY metro now with 70 as far north as central Ohio.  Warm front now as far north as the south Indianapolis metro with temperatures pushing 60.

Here 50s south of 24 will move in this evening with rain & few t’storms overnight.  North of 24, it should stay in the 40s.

It appears there is a meso-high of 1018 mb over the icy waters of Lake Michigan keeping the surface warm front south of our area today.  I have seen this every years I have been here, except 2012.  Lake Michigan’s icy cold water greatly affects the onset of spring here.  Cold air surging from the lake may retard spring by 2-3 weeks around here, compared to similar areas to the west & east.  If Lake Michigan were not there, it would be different.

HERE’S WHAT IS INTERESTING………………As cold air rushes in tomorrow morning & temperatures fall to 33-36 7 a.m. to 9 a.m., it is POSSIBLE that the rain may change to a period of wet snow.  The best chance is northeast of Lafayette, but I cannot rule out a changeover in the Lafayette area either.  If it snows long enough, grassy areas & car tops may be whitened.  It should melt quickly, however, with highs at 37-42.


Update

March 25th, 2015 at 2:17 pm by under Chad's WLFI Weather Blog

It is 70 around Columbus, Ohio now with mid 50s as far north as south side Indy Metro.

The Evansville, Indiana area is surging into the lower 70s, while parts of western Kentucky as now as high as 77.

North side of Dayton, Ohio is 57, southside is 66 as warm front lifts through that city.

Indianapolis International Airport has 50, but Shelbyville Airport is 55, while Franklin on southside of Metro is 57.

Here at WLFI, we continue to hold at 46.6 & have not budged a single bit for 1.5 hours.

Latest short-range models look to bring 60 line to Indianapolis & 50s south of U.S. 24 this evening.

Showers & a few t’storms will arrive overnight.

Below is projection for 1 a.m.

1

Rain may last into Thursday morning & end as some snow with best chance of this northeast of Lafayette.  If there would be any accumulation, it would be light.

As for the day, it just looks windy & mostly cloudy to cloudy with perhaps a few scattered flurries with highs of 37-41.  Low temperatures will drop to 23-27.

Scattered snow showers with mostly cloudy skies & windy conditions with record cold highs of 30-35 are likely Friday.  A dusting/coating of snow is possible in places with northwest winds gusting to 35 mph at times.

Lows of 12-17 Saturday morning will near/at record cold levels in our central & southwestern counties.  We will not even be close to the record in the north & northeast, however.  There, records lows at/below 0 occurred on the date due to snow on the ground.

Oddly, the record low of 13 for March 28 was set in 1934, which had one of the hottest, driest summers on record, just behind 1936!

Typical Late March Quirks: Two Different Seasons Over Indiana Today

March 25th, 2015 at 12:55 pm by under Chad's WLFI Weather Blog

We are holding at 47 at WLFI as of 1:15 p.m., north of the surface warm front.  Temperatures are now reaching 70 in the far southern parts of the state.

The forecast quandary is how far north the warm front gets.  Considerable rainfall over Oklahoma has forced from back to the central parts of that state, but clearing has forced it back north to around St. Louis to southern Indiana.

Current SPC Mesoscale analysis places the warm front roughly along U.S. 50 in southern Illinois & Indiana.

Thought is that as low lifts northward, front will lift northward, but I am doubtful with a more southerly track that the 60s will get into the area.  50s are possible, but not 60s.  The NWS NDFD does bring that 60 line to perhaps our southeastern counties this evening, but I think upper 50s are more likely.  NAM brings mid 50s as far north as U.S. 24, but that may be pushing it.

The best chance of 50s are south of U.S. 24.

Overall, it is just a difficult temperature forecast based on how far north the warm front gets.  One things for sure, it is not & will not move as far north as it looked yesterday & last night.

Another round of showers & a few t’storms will pass tonight.  Severe threat will remain south of our area.
