Area Forecast Discussion
National Weather Service Chicago/Romeoville, IL
213 PM CST Wed Nov 8 2017

.SHORT TERM...
210 PM CST

Through Thursday...

Biggest impact of the short term is a colder air mass spreads over
the region tomorrow behind an arctic cold front.

High pressure over the region will sink south tonight.  Cloud cover
will spread over the region, but I think we will be able to cool
pretty well before the clouds arrive. I lowered lows to below
freezing outside of the city.

The cold front will move through Thursday morning. CAMs continue to
indicate that a few flurries and light radar echoes may accompany
the front, but I'm thinking it'll be too dry for any snowflakes to
reach the surface.  The more noticeable change will be northwest
winds gusting to 25-30 MPH and colder air.  We should still see some
warming Thursday after clouds clear, and high temperatures will
range from the mid 30s to the northeast to the low-mid 40s in the
southwest.

.LONG TERM...
213 PM CST

Thursday night through Wednesday...

The period will start Thursday night with the coldest night of
the season thus far as a ~1038 MB surface high builds over the
Western Great Lakes Region. Temperatures are likely to drop into
the teens over north central IL, with 20s likely farther east
around and down wind of Lake Michigan where lake effect clouds and
precip will be possible.

Favorable thermodyamics over Lake Michigan with this very cold
airmass will likely to support a period of some lake effect snow
showers into portions of northwestern Indiana and portions of far
northeastern IL late Thursday night into at least Friday morning.
Overall, this does not look to be the best setup for significant
lake effect snow amounts over the area. This is due to limited
inversion heights (only 6-7 KFT), as well as the likelihood of a
quick progressive nature of the lake effect snow bands due to the
backing wind field Friday morning. So, while some accumulations
will be possible under some of the heavier snow bands, it appears
overall accumulations will remain on the light side.

Some light lake effect snow showers may continue into the early
afternoon over far northeastern IL, but the showers should be
waning with time as the winds turn southerly later in the day.
Otherwise, expect highs on Friday to remain cold, in the lower to
middle 30s.

Things will begin to moderate some Friday night into Saturday as
the flow turns southerly with warm air advection occurring ahead
of the next weather system over the Plains. This should result in
highs around 40 for Saturday. Precipitation chances still look to
increase across the area Saturday night into Sunday as our next
weather disturbance approaches the region. However, forecast
guidance continues to show differences in the timing, type and
extent of the precipitation across northern IL into Sunday. Due
to these uncertainties, we have continued with a mention of rain
and snow Saturday night into Sunday. At this time it appears that
if any snow occurs with this system, the marginal temperature
profile would likely significantly limit the potentially for any
meaningful accumulations.

Quiet, but cool weather looks to start the work week as surface
high pressure shifts across the region. However, temperatures
look to continue to moderate back to near 50 by the middle of the
week. There will also be another chance of rain Tuesday night into
Wednesday in association with another weather disturbance.

.AVIATION...
For the 18Z TAFs...

High pressure centered over the Mid Mississippi Valley will
continue to sink south through tonight. Light southwest winds are
expected tonight. An arctic front moves through Thursday morning.
VFR cloud cover and northwest winds gusting to 20-25 kt accompany
the front. Guidance indicates a brief period of flurries is
possible ahead of the front, but I did not have enough confidence
to include flurries in the TAF. No accumulation is expected. Some
guidance members also indicate MVFR cigs may be possible at RFD
Thursday morning. I decided to keep cigs at low end VFR. Skies
clear Thursday afternoon as a drier and much colder air mass moves
overhead.

.MARINE...
400 AM CST

A busy period is in store for the lake, especially Thursday and
Thursday night. High pressure ridging from the Plains to the Great
Lakes will sink south today, supporting westerly winds up to 25 kt
on the north half, and can't rule out sporadic 30 kt gusts. A
powerful Arctic cold front will approach from the north tonight,
with the cold frontal trough tightening the pressure gradient
across the lake and increasing westerly speeds/frequent gusts to
30 kt over the entire lake.

The cold front will quickly sweep across the lake Thursday
morning, with an extremely cold air mass pouring in behind the
front resulting in very unstable conditions/deep mixing. Low
pressure developing from the frontal trough deepening east of Lake
Huron and strong high pressure spreading from the northern Plains
will yield a very tight pressure gradient that will combine with
the deep mixing to produce gales Thursday morning through late
Thursday evening. Still have highest confidence in frequent gale
gusts up to 40 kt on the north half of the lake, but confidence
has increased in lower end gales also occurring on the south half.
Thus, have issued a Gale Watch for the open waters for the period
of concern. Not currently expecting gales in the Illinois and
Indiana nearshore waters, but certainly hazardous conditions for
small craft.

The Arctic high pressure will quickly shift east on Friday night,
with winds turning to southerly and increasing to 30 kt. 30 kt
southerly winds will persist through much of Saturday over the
open waters and at least occasional gale gusts are possible on
the north half of the lake. A cold front will move over the lake
Saturday night into Sunday, turning winds to lighter northerly.
