National Weather Service Milwaukee/Sullivan WI
240 PM CST Tue Jan 23 2018

.SHORT TERM...
Stratus is likely to continue into the evening but there is
uncertainty later tonight on when and if the stratus will become
few-sct. The subsidence and drying will be relatively weak with
MOS and fcst soundings showing mixed results. Another shortwave
trough will pass on Wed with mid to high clouds in the morning but
still with the potential for stratus to linger. Went slightly
milder with lows tonight given the clouds. Highs in the upper 20s
to lower 30s on Wed with some sunshine expected in the afternoon.

.LONG TERM...
Warm advection regime begins to develop over the region on
Thursday, ramping up substantially Thursday night and Friday.
Temperatures will surge to above average levels Thursday, with
readings around the 40 degree mark (give or take given lingering
snow cover). Well above average temperatures and breezy conditions
are expected Friday with temperatures around 50 degrees expected.
Depending on the extent of any lingering snow cover, we could warm
well into the 50s given abnormally warm 925/850mb temps.

Next shortwave/front moves through the region on Saturday.
Temperatures will drop back into the 40s for highs given fropa and
increased cloud coverage. Models have been trending bearish on
rainfall potential and have kept any PoPs on the low side and
confined to the southeastern half of the area.

Near/just above average temperatures round out the forecast Sunday
into early next week with lows in the teens and highs around 30.
Looking further ahead, extended range guidance continues to
indicate a roller coaster ride of temperatures with 2-3 day chunks
of above average temperatures followed by 2-3 days of colder
conditions.
