Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
557 PM CDT Tue Oct 9 2018

.UPDATE...

Diurnal convection is scattered across southern Wisconsin early
this evening. The stronger/severe convection has stayed up along
the stationary surface boundary stretching from near Prairie du
Chien, northeast through Marquette/Green Lake county. Effective
deep layer shear along this region is better than 40kts, combined
with MUCAPE of 1000-1500J/KG. Many of the storms have had
impressive rotation across Iowa, Sauk and Marquette counties, but
so far we haven't had a solid confirmation of any touchdowns.

We should see a rather quick downward trend in the activity with
the loss of daylight. The area should then get quiet for a time
before more showers and storms push in with the larger synoptic
system on Wednesday.

&&

.AVIATION(00Z TAFS)...

Showers and storms early this evening will diminish quickly by mid
evening. We should then get rather quiet until after about 12z on
Wednesday. That's when the showers and storms associated with an
advancing cold front begin to overspread southern Wisconsin.

Look for VFR conditions through the overnight hours, though any
storms could bring briefly lower conditions. MVFR then IFR
CIGS/VSBYS will quickly overspread southern Wisconsin by mid
morning on Wednesday, remaining low through the day as the slow
moving storm system tracks across the region. Improving conditions
are expected Wednesday evening as winds turn westerly and pull in
much drier air.

&&

.PREV DISCUSSION... (Issued 252 PM CDT Tue Oct 9 2018)

DISCUSSION...

Tonight and Wednesday...Forecast Confidence is medium to high.

Sct showers and tstorms will occur this afternoon with
SBCAPE's of 1500-2000 J/kg and no capping. Isold to sct showers
and storms will probably continue through the evening and
overnight via moisture transport, but the more widespread showers
and storms will occur on Wed. 1002 mb low pressure area over ern
KS will track to north central WI and gradually deepen to 997 mb
by 00Z Thu. The strong upper wave lifting nwd from the srn Rockies
to MN will continue the deepening Wed nt across Ontario, Canada.
A strong cold front will sweep ewd across srn WI late Wed aft-
early eve. PWs will increase to 1.8 inches tnt and remain high on
Wed until fropa. South to north bands of showers and embedded
tstorms will train some, but ewd movement will increase through
the day. Thus will not make any changes to the Flood Watch which
is in effect for Sauk, Iowa, and Lafayette Counties.

Wednesday night and Thursday - Confidence...Medium to High
Main story will be the arrival of the coldest airmass of the
season. Strong low pressure will shift to the northeast of Lake
Superior this period. A cold front will be whipping to the east of
the area with 850/925 temps crashing. Left a small pop in the
evening for potential for some lingering showers. Otherwise a
blustery period with most areas likely not exceeding the 50
degree mark on Thursday. And there will be the return of the wind
chill as well. So will be quite an abrupt change from the
warm/humid airmass from the days prior.

Thursday night through Saturday - Confidence...Low to Medium
This will be a cold period as the low level thermal trough is
sustained. The 12z ECMWF develops a system and brings precip
through the area Friday/Friday night. Meanwhile the GFS and GEM
show this system staying further south of the area. A light wind
regime and cold airmass could lead to the development of frost for
Thursday night in south central WI where it looks like a better
shot of some decoupling with the closer proximity to the incoming
ridge axis. And then the potential would expand to area wide
Friday night. If the ECMWF system were to pan out the clouds and
precip would would put the frost idea on the back burner. So for
now will steer more towards the frost idea panning out. Some WAA
sets up on Saturday between the departed high and ahead of an
approaching trough.

Saturday night through Sunday night - Confidence...Low to Medium
The trough/cold front moves through saturday night or Sunday
morning. By and large this fropa looks uneventful but some rain
showers do look possible. The 00z ECMWF had then developed a
potent low to our southeast with widespread rain and/or snow
Sunday night/Monday. The 12z run has backed off with a more
southern/weaker look. The 12z GEM stands as the strongest solution
with the highest qpf. So the GFS and ECMWF are now more or less
glancing shots of rain. 850 temps/1000-500 millibar thicknesses
look pretty chilly so some flakes wouldn't be out of the question.

Monday and Tuesday - Confidence...Medium
Surface/850 ridging takes hold then shifts to the east on Tuesday.
Another trough will bring the chance of showers to the forecast
later Tuesday or Tuesday evening.

AVIATION(21Z TAFS)...Cigs of 3.5 kft this afternoon into the
evening along with sct showers and storms. Cigs will then fall to
600-1900 feet from west to east across srn WI from early Wed
through late morning. The Cigs may improve to 1-3 kft during the
afternoon. Vsbys will be reduced at times tnt-Wed with the rain
and possibly light fog.

MARINE...A Small Craft Advisory is in effect from 12z Wed to 02z
Thu from Port Washington to Sheboygan due to high waves from a
persistent sly flow. Afterward, a Gale Watch is in effect from
02z Thu until 17Z Thu for the entire open lakes of Lake MI and the
nearshore area from Sheboygan south to Winthrop Harbor, IL. A
strong cold front will sweep ewd across the lake Wed evening with
wswly gale force gusts possible. The winds will gradually weaken
Thu aft-eve.
