Severe Weather Outbreak: November 17, 2013

November 17th, 2013 at 8:32 pm by under Chad's WLFI Weather Blog

HP SUPERCELL WITH TORNADO APPROACHING OUR WESTERN COUNTIES SUNDAY AFTERNOON:

44

MESONET STATION WEST OF KOKOMO MEASURED GUST OF 109 MPH AS TORNADIC CIRCULATION ON RADAR PASSED OVER THE LOCATION:

51

POTENTIAL TORNADO TRACK (SOLID OR DISCONTINUOUS) WHERE NWS TEAMS WILL LIKELY GO TOMORROW.  TRACKS BASED ON RADAR VELOCITY (THERE WERE A FEW OTHER MESO-VORTICES, BUT THESE WERE THE MAIN AREAS WITH TORNADO SIGNATURES).  THIS JUST GIVES A GENERAL IDEA:

48 50

Parameters prior to event certainly equaled other big severe weather outbreaks in our viewing area in the fall.  That will make this one rank up with the other big fall events we have had in the past +100 years of records.  Even November 26, 1856, widespread damage to structures, trees & fences was reported on & around the Wea Plains of Tippecanoe County & a spotted tornado killed 3 & injured 1 other person at a Potawatomi village in Newton County in October of 1841.  Tree damage & village damage was extensive as wind occurred around the tornado track.  A party of hunters observed the tornado with a vantage point on the prairie & marsh.  South of Indianapolis, a deadly tornado struck Franklin (Johnson County) October 1866 with major damage.

From a radar standpoint, there were many tornadoes today.  The Kokomo tornado looked like an EF3 on radar & many others looked like EF1s & EF2s.  Couple looked like EF0s.

In all of these, there were extensive, widespread, damaging straight-line winds of 50-75 mph.  Some of the gusts exceeded 80 mph & it is possible that some downbursts accompanied the large swaths of wind.

Some hail occurred of pea to quarter size, but not much.

One supercell around 11:30 a.m. was proceeded by a band of supercells, then a narrow, small squall line of showers/t’storms with the front that produced non-t’storm gusts of 45-60 mph.  This was followed by a nice rainbow in many areas.

Up to 1.89″ of rainfall occurred in the viewing area.

RESILIENCE……

There is a lot of damage in the area & NWS survey teams will be out tomorrow & perhaps Tuesday.

Sun is poking out in places, but there are still a lot of clouds keeping it from heating as much with 60s area-wide.  That said, severe threat is still high with tornado/wind/hail potential. 

Tornado is on the ground near Rantoul, Illinois moving northeast at 60 mph.  Supercell is about an hour from Benton County line.

Severe T”Storm Warning Newton, Jasper.  Gusts 60-70 mph possible with it.

Warning for Fulton & Miami counties cancelled.  Sun out in parts of our northwest counties.  Dew points surging to 62-65 with temperatures 63-68.

Violent HP supercells are in central & eastern Illinois with squall line west of there.

12:50 p.m.

Severe T’Storm Warning southeastern Fulton & northern Miami.  Gusts to 60 mph & 0.50-1″ hail possible.

Widespread wind damage & tornadoes are being reported in central Illinois, along with 1″ diameter hail reports.  WEET-TV studios is reporting damage & many homes are damaged in Tazewell County, Illinois.  A large tornado is on the ground in Tazewell & Woodford counties.  A cell tower was knocked down in Woodford County, Illinois.  Heavy damage near Peoria.

Tornado on the ground in La Salle County, Illinois with damage.  This is headed for southern & southwest suburbs of Chicago.  1.75″  hail reported near Rockford.

12:15 p.m.

PDS Tornado Watch is in effect for entire area until evening.

Supercells are racing through Illinois with confirmed tornadoes on the ground.  Meanwhile, supercell has congealed & weakened into a cluster of storms over White, Pulaski, Cass & Carroll counties.  Pea hail & gusts to 45 mph with heavy rain with it.

Approaching Noon, We Are Fair Game for Some Discrete Supercells

November 17th, 2013 at 11:17 am by under Chad's WLFI Weather Blog

11:25 a.m.

Severe T’Storm Warning Warren, Fountain, Tippecanoe until 12 p.m.

Supercell has rapidly popped near state line & is blossoming very fast & racing northeast at 60-65 mph!

Gusts to 60 mph & hail to 1″ in diameter possible.

11:13 a.m.

As we approach noon to 3p, we are fair game for discrete supercells with wind/hail/tornado threat.

The storms in central Illinois are actually forming in line segments.  This is most likely due to so much extreme shear & dynamics that the early-growing storms are staying low-topped & linear (shredded apart).  However, there is a supercell with a Tornado Warning in northern Illinois.

Thinking storms in Illinois will rapidly intensify with time as they begin to handle the shear with maturity from their current infancy & juvenile stages into adulthood.

Good news is that it is still cloudy over most of the viewing area, which is hold the temperature down to 64.  However, holes are developing in the stratus in our northwest & western counties with widespread sunshine in central Illinois.  It is 71 at Springfield, 75 at St. Louis, 67 Chicago & 67 at Champaign.  Dew points are running 60-65 there.

This said, instability parameters forecast are still likely to develop with time & the 1500 J/kg surface CAPE will spread eastward.


PDS Tornado Watch Newton, Jasper, Benton……Sun Out In Illinois

November 17th, 2013 at 10:02 am by under Chad's WLFI Weather Blog

Particularly Dangerous Situation (PDS) Tornado Watch has been issued until 5 p.m. for a good chunk of Illinois & Benton, Newton, Jasper counties.

Another one will likely follow east of there in the coming hours.

We are fair game for any supercell development 12-3p, then the main squall line (with supercells in front of it) will pass 3-7p.

Tornadoes are likely, including a large, long-track EF3-4 possible.  Widespread damaging straight-line winds & perhaps a downburst or two are possible.  Widespread gusts of 50-75 mph are likely with a few isolated gusts over 75 mph.  Some of the supercells may produce some large hail.  Storms will be fast-moving at 60 mph.

Rapid, impressive deepening of surface low will occur over the next few hours with +150 mph upper jet from the west-southwest atop +80 mph southerly low-level jet resulting in impressive directional & speed shear.  Surface instability of up to 1500 J/kg with an unusually warm, moist airmass with low LCLs will contribute to the risk.

It is already 70 at Pontiac, Illinois & 65 at Chicago.  At WLFI, we have 64 with a dew point of 60.

High Wind Warning is in effect until 9 p.m. for Benton, Jasper, Newton, Pulaski, Fulton, Miami, Cass, White for gusts as high as 60 mph as low deepens rapidly this afternoon & behind cold front this evening.

Wind Advisory is in effect for everyone else with gusts of up to 50 mph this afternoon & then with frontal passage this evening.

Updates will be hourly from here on out.

Significant, Dangerous Severe Weather Outbreak Sunday

November 16th, 2013 at 11:24 pm by under Chad's WLFI Weather Blog

Showers/t’storms will pass tonight-early Sunday.  Isolated severe storm or two is possible with wind/hail.

There may be some lulling with temperatures surging to 69-72 quickly by noon.  Then, noon-3p we will need to watch for the development of some scattered discrete, low-topped supercells.  These will have tornado/hail/wind threat.

The main squall line will race through in that 3-7p time frame all the while discrete cells continue to pop out ahead of it.

The squall line will have wind & tornado threat with it.  Also, heavy rainfall is likely.  Between tonight & tomorrow, still looks like a solid 1-1.5″.

South to southwest winds may gust up to 50 mph at times tonight-tomorrow outside of any storm.

All parameters, compared with past events & their parameters, support a widespread wind event with gusts of 50-75 mph with a few isolated gusts over 75 mph & a few EF0-EF2 tornadoes.

It is possible that there will be some EF3-EF4 tornadoes in parts of the Midwest/Great Lakes.  However, it is now unclear exactly where that will be.

The parameters all equal other significant late fall severe outbreaks in the region.
