Area Forecast Discussion
NATIONAL WEATHER SERVICE LINCOLN IL
306 AM CST Sun Jan 4 2015

.SHORT TERM...(Today)
ISSUED AT 305 AM CST SUN JAN 4 2015

Cold front is still moving through the CWA early this morning. As it
does, any mix of rain and snow ahead of the front will change to all
snow once the front passes. The heaviest snow is occurring well
northwest of the IL river and should remain north of most of the CWA
this morning. Accumulations of one half inch or less will be
possible this morning, mostly north of I-72, with the highest
amounts being north of I-74. Temperatures should fall during the day
as colder air advects into the area behind the cold front. Northwest
winds behind the front will also be gusty, with gusts to around
30mph. Skies will be cloudy during the morning, but then as the
500mb trough pushes through the area in the afternoon, clouds will
slide to the east. Skies should become partly to mostly sunny by the
late afternoon, with eastern IL improving later.

&&

.LONG TERM...(Tonight through Saturday)
ISSUED AT 305 AM CST SUN JAN 4 2015

Cold air will continue to plunge into the Midwest tonight and
Monday, with temperatures falling well below seasonal normals and
wind chills dropping well below zero throughout the forecast area by
Monday morning. Will be issuing a wind chill advisory for the
northern CWA, generally from Galesburg to Bloomington northward,
from midnight to noon Monday, where wind chills around -15F or so
are likely through mid morning.

Models differ on the track of the fast-moving surface low across the
Midwest which will should delineate where the southern edge of
significant precip lays out.  NAM from 00z keeps the low track near
I-80 suggesting heavier snow amounts should remain north of the
forecast area. The GFS at 00z however keeps a similar track across
the northern forecast area suggesting that the snow accumulation
gradient may be near I-74. Even the northern track NAM does show an
area of good isentropic lift (285K) over the northern third of the
forecast area with some negative EPV overlaying the lift at in the
700-600 mb layer. The models have also trended a bit faster, with
the GFS and ECMWF already bringing snow as far southeast as Peoria
by late Monday afternoon, and categorical PoP's will be used along
and north of I-74 Monday night. Have made some southward adjustments
with the PoP's overall in a nod to the GFS/ECMWF, with 30-40% PoP's
as far south as I-70. With cold temperatures in place in the
boundary layer snow-to-liquid ratios will likely by between 15-25:1
as suggested by BUFKIT soundings, so snowfall rates approaching an
inch an hour for several hours on Monday evening will be possible
near the QPF maximum. Any fluffy snow that does fall should blow
around significantly given the brisk 15-25 kt winds expected on the
back side of the system.

Intense high pressure area continues to be progged in the 1058 mb to
1060 mb range over the Dakotas and Nebraska on Wednesday. With 850
mb temperatures in the -24C range, the northern CWA will likely
struggle to reach zero on Wednesday. The coldest temperatures will
be Wednesday night, when double digits below zero are likely across
the north. Will eventually need to issue wind chill advisories and
warnings for Tuesday night through Thursday across most of the CWA,
but it is still a bit early to issue one.

Longer range pattern continues to keep a northwest flow over the
Great Lakes, but bottling up the core of the cold air to our north
late in the week. Timing of a shortwave on Saturday, in the area
between the phasing northern and southern branches of the jet
stream, is resulting in some model differences on snow potential on
Saturday. Have maintained the lower chances that were present west
of I-55 for now.

&&

.AVIATION...(For the 06Z TAFS through 06Z Sunday night)
ISSUED AT 1141 PM CST SAT JAN 3 2015

Predominantly LIFR ceilings across central IL, while fog and light
rain and drizzle produce visibilities mainly in IFR range. Rain
changing to snow will return as a cold front enter the area in the
next few hours, producing a decrease in visibilities. Boundary
layer remains saturated in model time height plots through mid-
morning, while another upper level disturbance moves through, so
little improvement in ceilings/vsbys should be expected until
afternoon. Drying and subsidence in northwest flow will begin to
bring improvements to MVFR category Sunday afternoon, along with
gusty northwest winds gusting 25 to 30 kts. After 00Z, drying
should produce a decrease in cloud cover ending MVFR ceilings,
while gustiness of winds should reduce, leaving a sustained 15 kt
W-NW wind.
