Attention early this morning is to off to our west where several

These disturbances are running along an impressive baroclinic zone
across the plains with 850mb temperatures of 14 deg C sampled
from the 0z DDC raob sounding and -10 deg C on the LBF sounding.
Snow is already falling from the Black Hills on ESE into eastern
NE and western IA. Looking at area obs in this corridor, snow is
mostly on the light side with some pockets of 1/2SM vis moderate
snow across western Iowa. This snowfall is mainly being driven by
impressive low-mid frontogenetical circulation due to the
tightening thermal gradient.

Extrapolating both radar and model progged fgen, snow should
begin to reach the southwest and southern portions of the CWA by
mid-late morning hours. There could be some virga initially out
ahead of the main area of snowfall given a little mid-level dry
air sampled on the DVN raob sounding this evening. As better
forcing arrives by the late morning ahead the digging shortwave
into southern IA/northern MO, and eventually western IL, the
entire column should quickly saturate and allow for snow to
quickly develop across the southern CWA, mainly south of I-80
with only light snow or flurries expected up to I-88.

RAP forecast cross sections through the f-gen band midday show
f-gen intensifying, deepening, and becoming less vertically
tilted allowing for stronger and deeper ascent. Given these
forecast trends in frontogenesis and some rather steeper mid-
level lapse rates, potential exists for some banded moderate to
potentially heavy snowfall. High resolution models are hinting at
this, increasing confidence in the potential snow could fall
rather heavily for a several hour period. Snow ratios during the
first half of the event look to be slightly worst than 10:1 but
should slowly increase with some cold air advection at 850mb by
afternoon from the northwest which will also help to slightly
deepen the dendritic growth zone cherry picking some NAM/HRRR
forecast soundings across the southern CWA.

While it is somewhat marginal, the banding potential and threat
for periods of moderate to heavy snow are concerning. After
coordination with ILX/DVN, decided to go with a winter wx advisory
for 2-4" of snow far southern 4 counties.

.LONG TERM...
308 AM CST

Thursday through Tuesday...

Thursday looks seasonably cold, though at least it looks sunny.
The Canadian high will pass south of the area late in the
afternoon with winds turning southerly Thursday evening. Looks
like we could have evening lows with rising temperatures after
midnight as southerly winds increase. Friday looks windy with
strong warm air advection, in fact, model progs have 925mb temps
warming from around -6C at 12z to around +6C at 00z. The cold
start to the day and the potential for cloud cover will probably
limit high temps from reaching their full potential, though 40s
still look attainable. Friday night should be unseasonably mild
with southerly winds continuing and low probably holding mostly in
the 30s.

Weak northern stream wave will pass north of the area later Friday
night with trailing cold front laying out east to west and slowly
sagging southward. Models have been wavering on how far south this
front will get Saturday, which should play a big role in temps as
gradient with this front looks large (especially near the lake).
South of the front high should easily soar into the 50s, with 60
even possible, while north of the front highs will struggle into
the 40s and near the lake probably hold in 30s as winds shift in
off the lake. GFS/ECMWF don't bring the front through until later
in the day which could allow for a mild start in Chicago/Rockford
areas, though given the cold lake and weak southerly flow in
advance of the front, am thinking the earlier fropa is more likely
with a stronger/faster backdoor front coming in off the lake. For
now, didn't make any changes to the model blended cocktail high
temps, but suspect there will be a larger gradient and likely
colder near the lake and warmer southern areas.

Southern stream wave still looks to ride up the stalling out front
later Saturday into Saturday night. While it will be chilly north
of the front, at this point, model forecast thermal profiles
strongly suggest an all rain event Sat night into Sunday morning.
No significant push of cold air behind the system with just a
continuation of seasonably temps and what looks to be dry
conditions to start off next week.

.AVIATION...
For the 06Z TAFs...

Ceilings are expected to gradually improve from 010-012 late this
evening to 018-022 overnight and winds are expected to remain out
of the WNW to NW with diminishing gustiness. Tomorrow morning,
an upper level disturbance is expected to move across the region
bringing light snow accumulations to portions of northern and
central Illinois and northwest Indiana. Accumulating snowfall is
still favored south of the terminals, though there could be some
occasional light snow or flurries at the terminals. Still feel
that better chances for snow will be during the afternoon as
another wave moves across the region, low level lapse rates
steepen and moisture increases. The signal is still marginal for
any appreciable snowfall, but will continue to carry a prob30 in
the meantime. Wind are expected to become northerly through much
of the day tomorrow, and some models suggest we could even turn
slightly NE (to roughly 020-030). For now NE winds remains a low
probability solution as a majority of models keep us 350-010.

.MARINE...
414 AM CST

Periodic active weather will continue over the lake through the
weekend. Today, conditions hazardous to small craft will continue
over the nearshore, mainly east of Gary. Steady north winds could
result in hazardous waves for the remainder of the Illinois and
Indiana nearshore, but opted to hold off on an advisory from Gary
to Winthrop Harbor for now. Tonight into Thursday morning, a
stronger push of cold air will arrive over the lake as expansive
high pressure spreads southeast from the Plains and a weak trough
hangs back across the central and eastern Lakes. This will support
northwest winds increasing to 30 kt over the entire lake. Am
concerned that forecast sustained speeds in the guidance and the
cold/unstable airmass could yield higher gusts near or to gale
force, especially on the southern portion of the lake. However,
confidence is low with forecast soundings not currently indicating
gales, so have opted to leave out any gale gust mention in the
open lake forecast.

High pressure will then quickly slide southeast Thursday night
into Friday as a fast moving low pressure approaches Lake
Superior. This is a favorable setup for south- southwest gales,
with the potential for high end gales depending on the strength of
the low. Will likely need a Gale headline for this period for at
least the open waters. Much lighter winds are then in store Friday
night through Saturday night. After a weak low pressure passes
over or just south of the lake Saturday night, the pressure
gradient between it and high pressure spreading east from the
Plains could yield northwest winds approaching 30 kt on Sunday.
