Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
932 PM CDT Sat Apr 21 2018


Mid/high clouds have been more persistent than expected so increased
cloud cover for the next several hours and therefore adjusted min
temps up a bit.



High pressure across New England will maintain a light easterly
flow across the area through Monday which will keep wave action


.PREV DISCUSSION... (Issued 616 PM CDT Sat Apr 21 2018)


No major changes made. Just updated near term cloud trends for
this evening. High pressure anchored across the eastern Great
Lakes will ensure dry conditions for the remainder of the weekend.


VFR conditions expected through the entire TAF period. High
pressure centered over the eastern Great Lakes will keep
conditions dry with a light E/SE flow. Mid/high clouds this
evening should diminish overnight with mostly clear skies

PREV DISCUSSION... (Issued 211 PM CDT Sat Apr 21 2018)


Tonight through Monday...Forecast confidence is High:

High pressure centered over the Great Lakes will move slowly
eastward over the weekend and into Monday, with the west end of
the ridge remaining across southern Wisconsin.

This high will bring dry weather to the forecast area through
this period. Temperatures will be around normal. However east
winds off Lake Michigan will bring cooling to east areas.

The band of altostratus across mainly southwest areas will
gradually thin. Most of the area will likely see some cirrus
due to an upper low moving across the Lower Mississippi River


Tuesday Through Friday...Forecast Confidence Is Medium.

Models are now more in line with trends during this period. A cut
off mid level low lifts northeast into the Ohio River Valley and
weakens, as an upstream trough moves across the Upper Mississippi
valley and Wisconsin Tuesday night and Wednesday. An accompanying
surface trough approaches southern Wisconsin, but weakens as high
pressure builds into southern Wisconsin.

For now, lower end PoPs for Tuesday night. Temperatures will be
near or a little above normal until a cold front moves in
Thursday.morning, moving southeast through the area during the
afternoon or evening hours. There is a 500 mb trough that moves
through the region either Thursday night or Friday. There seems
to be enough moisture with this system, so kept PoPs going for
Thursday into Friday morning. Temperatures look to cool later in
the week.


VFR conditions are expected through the TAF period. High pressure
centered over the Great lakes. Mid/high clouds across southern


High pressure centered over the Great Lakes.  Winds and waves will
remain low across the nearshore waters into early next week.
