Area Forecast Discussion
National Weather Service Chicago/Romeoville, IL
246 PM CST Wed Dec 28 2016

.SHORT TERM...
244 PM CST

Through Thursday Night...

Main forecast concerns/challenges are with the windy conditions
and snow showers that could impact the Thursday afternoon/evening
commute.

Strong WAA ahead of approaching system allowing for temps to rise
into the 40s this afternoon, despite mid/high level cloud cover
working its way overhead. This warmer air mass and temps will
linger into early this evening but will be short lived with colder
air returning tonight. This will be as cold front pushes through
the area later this evening, ahead of a digging large upper level
trough. Still anticipating conditions to remain dry later tonight
ahead of this system but guidance is still developing some precip
this evening, mainly with lifting energy ahead of the main trough.
Still feel confident that the stronger ascent/development will be
just east of the CWA, and so have continued a dry forecast
tonight. High level cloud cover should remain fairly transient and
likely depart during this evening. Although some breaks in the
clouds likely for a time this evening, do anticipate low stratus
to spread over the area late tonight into Thursday morning.

Upper level trough expected to still dig across the region, while
continued CAA ushers in colder air through the day. This along
with cloudy skies already in place by the morning, don't think any
big rises in temps will occur Thursday. Did lower high temps for
Thursday, capping highs in the low 30s. While surface gradient
really tightens up on the backside of this system and strong
mixing occurs, still expecting windy conditions, especially in the
afternoon. Am still concerned speeds/gusts will approach advisory
criteria for a time on Thursday, but don't have confidence for any
longer duration for these conditions. At this time, think these
higher gusts of 40-45 MPH will be occasionally observed. So have
capped gusts at 40 MPH, but do think this warrants monitoring for
possible more frequent higher winds/gusts.

Still continue to monitor snow chances Thursday and Thursday
evening and although am not anticipating any high snow amounts at
this time, do think there could be periods of higher intense,
moderate to briefly heavy, snow in the afternoon and early
evening. Morning guidance still varying with regards to this snow
potential with the GFS still the more aggressive with QPF
development. However, other guidance beginning to show some signs
of trending towards the GFS, though not quite as aggressive.
Nonetheless, anticipated pattern of CAA with steep low level lapse
rates, and large scale ascent in place owing to cyclonic flow with
shortwave energy traversing the flow would support at least
flurries or light snow showers for most of the day. Then, as low
level lapse rates really steepen in the afternoon, think there
will be an increase in snow intensity with more focused moderate
to briefly heavy snow development. This focus will likely be tied
to some low level convergence and confidence of where exactly this
will set up is lower at this time. However, at this time, areas
from Rockford, to Chicago, Valparaiso IN appear to have the higher
chances for this more intense snow. Have maintained similar snow
amounts generally keeping amounts under a half inch but do think
in the more intense snow that up to around one inch will be
possible. Despite the greater focus for lake effect snow staying
to the east, additional lake effect snow will be possible across
Porter county where one to three inches will be possible. The
timing of the more intense snow is a little concerning, with peak
snow likely occurring from mid/late afternoon into the early
evening. Road temp trends a little difficult to assess from this
standpoint but given the returning cold tonight and then time of
the snow tomorrow, do think that some snow sticking to the
pavement will be possible. If this were to occur, there could be
some slippery conditions for the afternoon/evening commute on the
Thursday. Although intensity of this snow should diminish later in
the evening, do think some continued scattered snow showers will
be possible into Thursday night.

.LONG TERM...
244 PM CST

Friday through Wednesday...

The period will begin on the quieter side as a ridge of high
pressure swings through the region on Friday. This high will
remain fairly progressive, exiting to the east by Friday night. As
this occurs, vorticity maxima over southern Canada and the upper
Midwest will steer deepening low pressure just north of Lake
Michigan Friday night into Saturday. Resultant southerly flow over
the area will bring another period of warmer air during this time,
but with this progressive pattern, expect cold air to quickly
return during the day Saturday. Guidance continues to trend more
southerly with any precip development Saturday and do think the
CWA will be dry. These dry conditions continue on Sunday with high
pressure spreading across the region. Early next week still
appearing to be fairly active with several periods of possible
weather. Still some variability with overall solutions but Monday
is appearing to be on the milder side. However, confidence fairly
high of much colder air returning by the end of the forecast
period.

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

1146 am...Two main forecast concerns are winds through the period
and snow showers Thursday afternoon.

Southerly winds are now gusting into the 25-30kt range and these
gusts will continue through sunset when winds turn more to the
southwest with the passage of a cold front. Speeds/gusts will
diminish early this evening but will slowly increase overnight as
winds turn more westerly. Gusts will likely increase back into the
20-25kt range by sunrise. Low levels begin to mix Thursday morning
and continue to mix deeply into Thursday afternoon. Gusts likely
to increase into the 30-35kt range by late morning/early Thursday
afternoon. A few higher gusts are possible especially mid/late
Thursday afternoon.

The deep mixing Thursday afternoon will lead to unstable
conditions that will result in snow showers or even snow squall
development by early/mid afternoon which will continue into
Thursday evening. While duration may be brief...some of these snow
showers/squalls may lower vis/cigs to ifr. From this distance...
for the 30 hr ord taf...added prevailing snow showers with a
tempo for mvfr vis. Possible that lower conditions may be needed
with later forecasts.

High/mid clouds this afternoon will scatter later this evening.
Lower cigs will redevelop/spread back across the region overnight
into Thursday. Its possible cigs may lower to mvfr but confidence
is low through much of Thursday morning. cms

&&

.MARINE...

123 pm...A cold front will move across Lake Michigan this evening
with southerly gale force winds turning more southwesterly and
then diminishing later this evening. Low pressure will develop
over Ontario tonight and then move to New England Thursday where
it will merge with stronger low pressure developing along the east
coast. As this low deepens tonight and the gradient tightens along
with colder air spreading back across the region...Westerly winds
will increase back to gale force over the southern half of the
lake Thursday morning and these gales will likely continue into
Friday morning. Its possible gale force winds will also develop
over northern portions of the lake but confidence remains low so
will maintain current gale gust mention. A ridge of high pressure
will quickly move across the lake Friday afternoon.

Low pressure will move from the northern plains Friday afternoon
to the far northern end of the lake and the upper peninsula
Saturday morning. Strong southerly winds will develop Friday
evening as this low approaches and a period of gales is possible
over the southern half of the lake. A trailing cold front will
move across the region Saturday morning shifting winds westerly.
There could be a brief period where the gradient is tight enough
for some gale force winds Saturday afternoon but high pressure is
quickly moving from the central plains to the southern lakes
region Saturday night...so confidence is low regarding potential
for gales during this time period. cms
