SHORT TERM. (Issued 210 PM CST Sun Mar 7 2021)
Tonight through Monday night:
Temperatures this afternoon have reached the low to mid 40s, with filtered sunshine as a batch of cirrus moves through the region.
A shortwave approaching from the Dakotas will pass through the area tonight, pushing a weak surface trough into southern Wisconsin, with winds becoming light from the west. Will need to watch for patchy fog tomorrow morning in a few spots, especially where the remaining snow pack is most widespread. Lows tonight should reach the low to mid 30s.
Continued warm advection will help boost temperatures into the 50s tomorrow, with a few 60s not out of the question south and west of Madison. Lows tomorrow night will again fall into the low to mid 30s.
LONG TERM. (Issued 210 PM CST Sun Mar 7 2021)
Tuesday through Sunday:
Deepening low pressure over the central and northern Plains will allow the surface warm front to lift north into the area Tuesday, and continue to mix northward on Wednesday. Highs both days are expected to be in the low 60s for most locations, with readings perhaps just a touch warmer on Wednesday. South to southwest winds will be breezy both days, but especially on Wednesday, with some gusts in the 20 to 30 MPH range at times.
Ascent will start to increase across the area on Wednesday as a cold front begins to approach from the west, and heights aloft continue to fall. As moisture increases, we will likely see isolated to scattered showers expand in coverage through the day. A few rumbles of thunder will be possible as well, especially Wednesday evening and night as better moisture and lift arrive. Right now, a quarter to half inch of rain appears most likely, with the higher amounts of QPF across the northwestern half of the forecast area. Since a good deal of the snow pack has been allowed to melt already, this amount of rain should not cause any major flooding concerns, though with the ground still partially frozen and ice in many area rivers, some minor issues could crop up.
The front will pass through the area Wednesday night, with post frontal rain lingering into the day on Thursday. The front should continue to push south over time, with Friday currently looking dry. Temperatures both days will be cooler but not unreasonable for mid March, with highs in the low 50s on Thursday and mid to upper 40s on Friday.
Another wave is expected to move into the region over the weekend, though right now there is considerable uncertainty regarding timing and strength of this system.
AVIATION. (Issued 210 PM CST Sun Mar 7 2021)
VFR will prevail for the rest of today, with just passing mid and high level clouds. Winds will be from the south and southeast.
A surface trough will move into the area this evening into tonight. Ahead of this, a strong low level jet will result in LLWS at the terminals, while at the surface, winds will become lighter from the west and southwest. There is some potential for patchy fog and/or low stratus in a few areas late tonight/early tomorrow morning, though the potential is too low right now to include it in the TAFs.
Aside from any linger early morning fog/stratus, look for VFR through the day tomorrow, along with west to southwest winds.
MARINE. (Issued 210 PM CST Sun Mar 7 2021)
A Small Craft Advisory remains in effect for areas north of Port Washington for this evening and tonight, due to building waves. Lighter offshore winds are expected by morning, continuing through the day on Monday.
Winds will start to increase from the south on Tuesday and especially Wednesday, with speeds approaching gale force at times over the open waters, especially on Wednesday. Right now, it appears that limited mixing due to the cold lake waters will keep speeds just below gales, but it will be close. The persistent south winds will result in significant waves over the northern portions of the lake.
For the nearshore, winds and waves will likely necessitate a Small Craft Advisory during this time.
