The potential for patchy frost development early Saturday morning remains with temperatures remaining around the low to mid 30s and winds consistently clocking in around 10 knots overnight tonight. Else, rest of forecast remains on track, with gusty winds during the day and warming temperatures up to the lower 50s.

SHORT TERM
Issued 1015 AM CDT Fri Apr 19 2024

Today through Saturday:

Skies have cleared early this morning as dry air filters into the area. A windy day is ahead, with a deeply mixed boundary layer helping to bring some higher westerly gusts to 35 MPH down to the surface. Highs today will generally be in the upper 40s to low 50s, with the cooler temperatures across central Wisconsin, where a scattered to broken stratocu deck is expected to develop by afternoon. Couldn't totally rule out a sprinkle or two making it down to the surface, but very dry air in the low levels will limit this potential.

Lows tonight will fall into the low to mid 30s. Winds will remain breezy enough overnight to limit frost formation, but freeze headlines may be needed later today if temperatures are still expected to bottom out around 30.

Slightly cooler and less windy conditions are expected on Saturday, with highs in the upper 40s.

LONG TERM
Issued 257 AM CDT Fri Apr 19 2024

Saturday night through Thursday:

Frost may be more of a concern Sunday morning, with lighter winds expected late Saturday night. Lows will again be in the low 30s. A surface ridge and warmer air aloft moving into the area will help boost temperatures into the mid to upper 50s on Sunday. Winds turn southwesterly for Monday, with highs expected to reach the low 60s.

Rain chances increase into the 50-70% range Monday night and Tuesday as another upper level low moves through the area.
Seasonable temperatures in the mid to upper 50s are expected behind this system for the middle and end of the workweek.

AVIATION
Issued 1015 AM CDT Fri Apr 19 2024

Patchy diurnal cu has begun developing across south central Wisconsin, which will become more extensive later in the afternoon today spreading down from the north. Gusty west winds will strengthen and persist during the day, before tapering off around the evening.

Issued 257 AM CDT Fri Apr 19 2024

Gusty west winds winds are expected today and tomorrow, as low pressure moves from Ontario into Quebec, and high pressure extends from the northern High Plains across the middle portion of the country. Winds over the open waters are expected to remain just below gale force. For the nearshore, a Small Craft Advisory is in effect starting mid morning today and continuing through the afternoon. The westerly winds will become lighter on Sunday as a surface ridge approaches from the west, and then will turn southwesterly early next workweek.
