Latest Christmas Outlook

December 20th, 2014 at 10:50 am by under Chad's WLFI Weather Blog


A few flurries & snow showers are possible today.  If there is any accumulation, it would be like yesterday & day before, just a patchy dusting.  Some patchy freezing drizzle is possible tonight.  Amounts should be trace-0.01″

Sunday looks gray & warmer with some fog & perhaps patchy drizzle with highs near 40.


Rainfall totals are looking higher for Monday-Tuesday.  By Tuesday night, 0.75-1.25″ totals are looking increasingly likely.  On the western side of this system, it appears a 4-7″ snow band may develop from central Missouri to southeastern Iowa & perhaps far western Illinois.

This would make it the first substantial, significant rainfall in nearly a month.  The heaviest rainfall looks to come through with rapidly-deepening storm Tuesday late morning-early afternoon.


As strong storm pivots northward through Illinois & into Michigan, gusty southwest winds to 32 mph & temperatures of 45-50 will be replaced with northwest winds to 40 mph & falling temperatures into the 30s on Christmas Eve Day & 20s Christmas Eve night.

Wind-driven snow showers are likely Christmas Eve Day & Night.  Up to 1″ of accumulation is possible.

Christmas Day still looks dry, windy & cold at the moment with highs in the 20s.

We still need to watch December 26-27 for snowfall potential.  Still questionable how much impact that system will have on us, but accumulating snowfall still looks like a good bet from Missouri to Nebraska.

Some Snow & Freezing Drizzle In the Forecast (But Also Rain with Quick Warm-Up)

December 19th, 2014 at 1:25 pm by under Chad's WLFI Weather Blog


I still think a few scattered snow showers are a good bet Saturday.  If there is any accumulation, it would be a dusting.

Saturday, I still think some freezing drizzle could develop.  This could lead to slick spots on roads.

Gray, rather foggy Sunday may occur as warm air overrides the cold ground with highs near 40.


Monday looks gray, foggy, drizzly & rather showery with 45-50 with brisk southwest winds.

It looks murky, gray & showery Tuesday.  In fact, they look more widespread than Monday with highs of 45-50.  Right now, it looks like 0.50-0.80″ may fall Monday-Tuesday.


Snow showers are still likely Wednesday with strong winds (gusts to 40 mph) to the northwest.  Up to 1″ may accumulate.  With the strong winds, it will blow & drift around, too.

Christmas Day looks dry & partly to mostly cloudy, but windy with northwest winds to 40 mph.

The day after Christmas, there is going to be widespread snowfall Missouri & Iowa to Nebraska.  This system could bring snowfall that night or a couple of days after Christmas.  Details including timing & amounts are still blurry at best, but trends suggest a 1-2″ snow with this one.


Several Interesting Things Noted In Latest Data

December 18th, 2014 at 10:50 pm by under Chad's WLFI Weather Blog

With mostly cloudy skies, highs in the lower 30s are likely for Friday with 20s Friday night.

I still like 20-25% POPs for Saturday with a few snow showers with 30s.

Temperature will likely level off near 30 Saturday night & I would not be surprised to actually see a little bit of patchy freezing drizzle as warm air advection gets underway.  We may even rise to near 32 by Sunday morning.

Sunday looks mostly cloudy & much warmer with highs of 38-45 as plume of warm air surges in.

Some scattered showers are likely Monday with 45-50 with showers & 45-50 Tuesday.

Snow showers are likely with 1″ or less of accumulation with 30s & strong northwest winds to 40 mph.

Christmas currently looks dry with any snow showers exiting & highs in the 20s with strong northwest winds to 40 mph at times.

Christmas night-day after Christmas does look like snow, but accumulations are unclear.  Though confidence is low on exact amount, I think a 1-2″ snow may occur with heavier totals west of our area.  This is based on all of the data & evidence I have to make that call at the moment.

All trends point to cold weather December 27-30 with highs near 20 to into the 20s with lows in the single digits to lower teens.

Stay tuned for the latest updates as new data arrives.

Latest Detailed Outlook Through Christmas

December 18th, 2014 at 4:37 pm by under Chad's WLFI Weather Blog


We have had some scattered snow showers today & a few of you have gotten a dusting.  Any snow showers/flurries will exit this evening.

Skies will remain mostly cloudy to cloudy tonight with 20s, then mostly cloudy skies & 30s tomorrow.


With mostly cloudy skies, a few snow showers & flurries are possible Saturday with highs in the 30s.

Sundays look dry & mostly cloudy with 30s & lows in the upper 20s.


It does look like a brief surge of warmth Monday Tuesday with highs near 40 Monday 45 (50 south?) & some scattered showers are likely as clipper dives southeastward.


As clipper winds up over the Great Lakes, scattered, wind-driven snow showers will pass Tuesday night-Christmas Eve.  1″ or less of accumulation looks likely.  Northwest winds may gust to 40 mph, though, with highs in the 20s & lows in the teens.

Right now, Christmas Day looks dry, windy & cold with highs in the 20s, HOWEVER, there will likely be accumulating snowfall from western Illinois to Nebraska with clipper.

It is unclear how much of an effect this system will have on us Christmas night-Friday.  It COULD bring accumulating snowfall.  A more focused forecast will develop over the next few days as better data arrives.


Colder trend looks to settle in after Christmas with highs below normal in the 20s with lows in 10-13 range.  Some places may even drop to the single digits.


Up to 6″ Snow Southwest of Here…..Few Snow Showers Possible Here Today

December 18th, 2014 at 10:25 am by under Chad's WLFI Weather Blog

Some snow showers are hanging on just long enough to make it into eastern Illinois.

These will move into our area noon & onward.  Coverage will only run around 20-25%, as not all of the snow on radar is reaching the ground, however, some of it will.  Any accumulation will be patchy & only amount to a dusting.


Up to 6″ of snowfall has been reported in Kansas & 5″ in Missouri.  Many places reported 3 & 4″.  The two intense bands had the 5.5-6″ amounts.

Accumulating Snowfall Southwest of Our Area

December 17th, 2014 at 10:08 pm by under Chad's WLFI Weather Blog

Most models completely dry up absolutely all of the snow over Missouri to Illinois tomorrow as it moves eastward.  This will partially be the case as high pressure acts as a wall to this system & any movement northeastward.

However, I would not be surprised if at least some snow showers last long enough to get in here.  I still like 20% POPs for tomorrow for snow showers with any accumulation being less than 1″.  We will monitor this, as if the snowfall holds together even better, then POPs would need to be increased.

Right now, some very intense banding of snowfall is occurring in east-central Kansas & over south-central Missouri with locally 1-2″ per hour rates.


Several Systems Of Note Through Christmas

December 17th, 2014 at 1:49 pm by under Chad's WLFI Weather Blog


A general 1.5-4″ snowfall is likely across Kansas, Missouri & western Illinois tonight-Thursday.  However, I think two main band of intense band will dump 4-6″.  One is likely in Kansas, the other in central Missouri.  Band #1 in Kansas will largely be in frontagenetical forcing at first, then become a deformation zone of intense snowfall.  Band #2 will be a focus of intense frontagenetical banding in Missouri.  This is also where baroclinically-induced, nocturnal low-level jet will forcing moisture & bits of elevated instability (which will enhance the snowfall).

Now, this system will encounter wall of surface high pressue in our area Thursday afternoon & rapidly fall apart.  However, there are subtle model indicators that suggest some scattered snow showers may hang on just long enough to make it into our area later Thursday with perhaps a dusting in places.  Confidence is not high on that, but is such that 20% POP is warranted & inclusion of a “less than 1″” potential zone painted.

NWS has Winter Weather Advisories up in these areas & they may put out localized Winter Storm Warnings eventually in those zones of greatest forcing.



Second system may spread a 1-2″ band near the Ohio River Saturday.  If we would happen to get anything from that, it would be very light.  We will continue to monitor.

I still  have 20% POP for Saturday for any snow shower, due to some degree of uncertainty.

203 401208


Still looks like colder regime around Christmas.  We will have to keep an eye on third system that will bring accumulating snow to parts of the Rockies & Plains.  Potential is still there for snow around Christmas.

Christmas Day still looks windy & cold with highs in the 20s & lows in the 10-15 range.

There is some earmark of a brief, sharp warm-up of 40s to perhaps 50 for like one day, but I do not know whether that is before New Year’s.  Timing is blurry at best, but there is like one day of intense warm air advection with quick warm-up.  I hope to pin the timing down in upcoming posts.



Latest Outlook to January 1

December 16th, 2014 at 11:05 pm by under Chad's WLFI Weather Blog

Cold air got in just before last of the drizzle ended, leading to period of grainy light snow.  Some of you may have gotten a powdered sugar dusting.

Lots of clouds will dominate the rest of the week & into the weekend with highs in the 30s.

There are three snow systems to watch to December 26.

System #1 will bring 2-4″ of snowfall to parts of eastern Kansas & Missouri & perhaps 1″ as far east as central Illinois Thursday.

Right now, it looks like this system will die out rapidly as it encounters strong high pressure over our area.


System #2 will likely track farther south with band of snowfall perhaps along the Ohio River to the Northeast.  Here, it may bring a few snow showers Saturday.  If there is any accumulation it would be less than 1″.

System #3 looks to dive out of the front range & bring scattered rain/snow to our area initially around next Tuesday.

Widespread accumulating snowfall is possible Colorado to Missouri.  There is uncertainty regarding how much influence it will have here, but some data suggests some accumulating snowfall just before/around Christmas.

It still looks like a cold Christmas with highs only in the 20s & lows of 10-15.

There are signs of a brief, sharp warm-up near New Year’s to 40s, perhaps 50.  However, confidence is not high on that, still.




Drizzle Changing to Snow Grains Before Exiting

December 16th, 2014 at 10:10 pm by under Chad's WLFI Weather Blog

Drizzle is hanging on long enough to change to snow grains as of 10 p.m. as temperatures drop aloft & at the surface before the drizzle exits.  A light dusting is possible.  It is still all drizzle in the far northeast.  Watch for slick spots.

Lows tonight will drop into the upper 20s to around 30.

With cloudy to mostly cloudy skies tomorrow, a few flurries are possible.  Highs will run near 36.
