Area Forecast Discussion

.DISCUSSION...
ISSUED 330 AM CST Tue Feb 25 2014

Will issue a wind chill advisory (wind chills 15-25 below zero) along
and north of a Fulton to Mason to Logan to Dewitt to Piatt to Champaign
to Vermilion county from midnight tonight through 10 am Wednesday
morning.

SHORT TERM...Today through Friday night

Area of light snow and flurries over central IL will diminish
across the area during early morning. A few area like Lincoln had
over 1 inch of snow as vsbys lowered to 1-2 miles. The short wave
over southern Lake Michigan will quickly pass east across the
southern great lakes this morning taking its light snow out of
central IL during early this morning with mainly a dusting of
additional accumulations. Models continue to show some light
snow/qpf south of I-70 this evening and have 20-30% chance of
light snow there with less than half inch of snow possible along
and south of highway 50. A fair amount of clouds today with highs
ranging from upper teens and lower 20s north to the low to mid 30s
in southeast IL.

Another arctic airmass ushers into IL during overnight into Wed
with brisk nw winds, with wind chills reaching 15-25 below zero
along and north of a Canton to Lincoln to Danville line. Therefore
will issue a wind chill advisory overnight until 10 am Wed
morning. Lows to reach single digits below zero over northern
counties while 5-10F over southern counties.

Arctic high pressure weakens as it settles into OK and Ozarks by
18Z/noon Wed. Cold highs Wed in the upper teens and lower 20s over
central IL despite return of sunshine. NW winds turn SW during the
day Wed and still rather brisk and adding more chill to the air.
Lows Wed night in the single digits central IL and lower teens in
southeast IL.

A strong northern stream short wave digs into the upper great
lakes wed night and drives another arctic cold front se through IL
and passes through dry due to limited moisture and dynamics/lift
passing to our north/ne. So a reinforcing arctic airmass into the
region during Wed night. Wind chills could reach around 15 below
over colder northern counties later Wed night into Thu morning so
another wind chill advisory may be needed then.

A fair amount of sunshine but still cold again on Thu as canadian
high pressure settles into IL by sunset Thu. Highs Thu range from
lower teens northern counties to lower 20s in southeast IL.

A weak weather system to bring chance of light snow to region Fri
and Fri night with snow accumulations generally half to 1 inch
possible similar to what occurred this past night.

LONG TERM...Saturday through Monday night

Below normal temperatures look to continue this 1st weekend of
March into early next week. Dry conditions still on tap Saturday
but that appears to be short lived. A stronger southern stream
storm system to have surface low pressure eject ne from the
southern plains into the TN river valley Sunday and Sunday night
likely bringing accumulating snows to central and southeast IL.
Still some question about snowfall amounts and southeast IL may
even see a mix of wintery preciptation Sunday. Will need to
monitor later forecasts on this weather system which could impact
travel plains later this weekend.

.AVIATION...
ISSUED 1149 PM CST Mon Feb 24 2014
Shortwave interaction with sfc boundary and finally saturating
down to the surface spreading snow across the FA. For the next
couple hours, snow will spread as cigs drop. IFR visibility and
eventually the ceilings will drop. Both line from SPI to CMI that
is more dynamically forced will be dropping south and the light
snow will spread to all terminals. Heaviest snowfall falling from
SPI to DEC to CMI and will slowly move south this evening. Snow
may move south quicker than the vis can drop for a signif time
frame from SPI to CMI. Snow ending before dawn. BKN low until the
sun comes up and we get a little bit of a lift of the deck. GFS a
little thinner with the saturated boundary layer tomorrow...but
not until later in the day. Sun will not likely have enough time
to completely eliminate the stratus.
