Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 847 AM CDT Sat Jun 12 2021

UPDATE. (Issued 847 AM CDT Sat Jun 12 2021)

Still a window for some development into far SE WI this afternoon. Meso models are not impressive with this, but lingering inverted trough axis combined with instability axis could still set something off before the northwest winds and drier dew points take hold. Already seeing this evolve across southwest WI.

SHORT TERM. (Issued 352 AM CDT Sat Jun 12 2021)

Today through Sunday:

A cold front will push through the area by mid to late morning today. The deeper moisture and better instability will linger a bit longer until the shortwave clears the area by mid/late afternoon. May see a few showers and a storm or two along the frontal boundary this morning, with maybe a few more storms in the east this afternoon as the shortwave moves through. It could be the majority of shower/storm activity stays more closely tied to the surface convergence with the front, which would keep most of the storms east of the area today.

Temps will be warm and sticky again most places today, though dewpoints will begin dropping from west to east late morning through the afternoon behind the front. A lake breeze will keep temps down a bit in the east, especially late morning and afternoon.

Deeper moisture will continue to depart this evening into tonight, with dewpoints falling low enough to possibly see some temps fall below 60 for the first time in a while. Temps aloft will recover a bit Sunday ahead of an approaching low, allowing temps to push 90 once again away from Lake Michigan. The low will move through Sunday night, possibly bringing a few showers/storms to the northern forecast area.

DDV

LONG TERM. (Issued 352 AM CDT Sat Jun 12 2021)

Monday through Friday:

High pressure will be running the show much of the time the first half of next week, with plenty of sunshine expected. Temperatures will be back towards normal value Mon-Wed, though likely remaining a couple/few degrees above normal away from Lake Michigan. The lower dewpoints will hang around, keeping humidity levels at a comfortable level.

Low pressure and a cold front is expected to be approaching the area on Thursday. Southerly winds ahead of this system will likely bring increased temperatures back into southern Wisconsin, with highs back near 90. Moisture will be slow to return, with dewpoints not increasing substantially until the front draws near Thursday evening. Looks like a decent setup for some showers and storms, but current model timing shows the front moving through late in the night into Friday morning. This would be pretty poor timing for decent instability, possibly limiting storm strength and coverage.

Temps are trickier for Friday, all depending on how quickly the front exits to the east. Overall, looks like a window of opportunity for some mid/upper 80s to sneak in ahead of the front.

DDV

AVIATION. (Issued 847 AM CDT Sat Jun 12 2021)

Inverted trough axis into ern WI with onshore flow continuing before passage. Weak convergence and instability axis could still pop an isolated storm or two this afternoon before drier northwest winds take hold tonight. VFR conditions this period.

MARINE. (Issued 352 AM CDT Sat Jun 12 2021)

Light northerly winds may be variable at times today. More persistent north to northwest winds will develop later today into tonight as a cold front moves through the area and high pressure of 30.0 inches begins to build in from the west. Low pressure of 29.8 inches will drop through the area later Sunday into Sunday night, with breezy north to northwest winds likely behind the low Sunday night into Monday.
