Area Forecast Discussion
National Weather Service Chicago/Romeoville, IL
548 AM CST Fri Nov 18 2016

.SHORT TERM...
345 AM CST

Today through Saturday...

Deep surface low pressure system will lift from Iowa northeast
across the Upper Mississippi Valley and northern Great Lakes
through this evening, in response to a deepening mid-level trough.
The track of this system will produce breezy and unseasonably mild
warm-sector conditions across the forecast area through mid-day
before the strong trailing cold front plows east across the cwa
this afternoon. South of the main low track, precipitation is
expected to be limited to showers developing along/ahead of the
cold front within fairly narrow ribbon of low-level 50+ degree dew
point air during the mid-day and afternoon hours. Height falls and
steepening mid-level lapse rates in advance of the upper trough,
juxtaposed atop warm/moist low-level advection ahead of the front
will lead to a brief increased thunderstorm potential too, which
may support an isolated damaging wind threat given strong 40-50 kt
winds just above the boundary layer. SPC has included the
southeast half of the cwa (roughly along/southeast of the I-55
corridor) in a marginal severe risk by early this afternoon, where
surface/near-surface based convection will be most likely. Cold
frontal passage will shut off precip threat, while a shift to
gusty west winds signals a temperature drop from mid-upper 60's
into the 50's and even some upper 40's behind the front by
evening. Surface pressure rises and steep low-level lapse rates
resulting from strong cold advection will likely produce wind
gusts of 35-40 mph late this afternoon/early this evening, with
perhaps a few higher gusts just behind the front. Overall, this
looks to be just below wind advisory criteria and will not be
issuing headlines, but will bear watching and will definitely be
windy going into tonight. While initially dry behind the front,
deeper moisture wrapping around the departing system tonight
should eventually produce some showers especially after midnight
tonight and into saturday morning especially from the I-80
corridor northward, and thermal profiles would support a mix and
change over to snow showers by Saturday morning as surface
temperatures dip into the low-mid 30's. Not much in the way of
accumulation is expected, though a few areas across far northern
IL could pick up a quick dusting before much drier air moves in
aloft later in the morning. Lake effect showers will be focused
east of the cwa for the most part, though parts of northeast Lake,
and much of Porter county may see scattered rain/snow showers
lingering into Saturday afternoon. Temps Saturday are expected to
top out near 40, though most of the hours in the day will be in
the mid-upper 30's, with blustery winds keeping wind chills in the
20's. Truly our first taste of winter. Winds finally diminish
Saturday night as the low pulls away and surface high pressure
spreads into the Mississippi Valley overnight. Decreasing clouds
and winds will set up a chilly night however, with lows in the
low-mid 20's.

.LONG TERM...
354 AM CST

Sunday through Thursday...

The upper pattern remains progressive through next week, with
broad upper ridging developing across the Midwest in the wake of
our departing weekend trough. Chilly surface high pressure lingers
Sunday with little bump in temps over Saturday's highs expected,
though moderation back into the 40's and lower 50's (average for
late November!) is anticipated by Monday/Tuesday. Medium range
guidance is in general agreement in bringing another weaker upper
trough into the region by mid-week, with a surface low progged to
track across northern IL or southern WI Wednesday or Wednesday
night. This would bring the potential for precipitation back into
the region as early as Tuesday as warm advection isentropic ascent
develops, though the track and thermal fields would support rain
for the forecast area. Another quick moving disturbance is
depicted with relatively good model agreement by Friday.

Ratzer

&&

.AVIATION...
For the 12Z TAFs...

Strong winds will develop this morning and continue through most
of the TAF period as a strong cold front sweeps across the
region. Southerly flow is expected to ramp this morning out of
180-200 with gusts eventually pushing into the 26-28 kt range,
though cannot rule out a few sporadic 30+ kt gusts, especially in
and near any precip activity this afternoon. Guidance in decent
agreement showing a line of showers and thunderstorms developing
across central and northern Illinois. The Chicago area terminals
will likely be on the northern end of the line with the bulk of
the activity extending south in a N- S line. Timing should be
early to mid this afternoon, with precip chances winding back down
as the cold front pushes through mid to late this afternoon. With
frontal passage, expect winds to veer to the southwest 240-250 and
deeper mixing will tap into stronger gusts, well into the 30 kt
range. Winds will continue to gradually veer overnight eventually
reaching 290-300 by late tonight, but are expected to remain quite
strong through the overnight hours.

BMD

&&

.MARINE...
307 AM CST

A powerful cold front remains poised to sweep across lake Michigan
Friday night into Saturday ushering in a much cooler airmass
along with high end gales and the potential for a window of storm
force gusts. Low pressure is in place across the mid-Missouri
Valley early this morning and will lift to the upper peninsula of
Michigan this evening. Southerly winds are expected to ramp up
today out ahead of the low with Gales possible by early this
afternoon and increasing to around 40 kt by this evening. Winds
are expected to shift out of the northwest by late tonight into
early Saturday as a trailing cold front sweeps across Lake
Michigan. Guidance continues to advertise very strong gales behind
the front with a window of storm force gusts across the north half
of the lake from mid/late Saturday morning through late
afternoon/early evening. A Storm Watch remains in effect for this
timeframe. Winds should very gradually diminish back below gale
force by around midday Sunday, then continue to taper to 10 to 20
kt by midday Monday.
