KEY MESSAGES
- Rain showers and isolated thunderstorms are forecast for tonight.
- Periods of light to moderate rain are forecast Sunday through Tuesday.
UPDATE
Issued 916 AM CDT Fri Mar 29 2024
Periods of mid and high level clouds will continue today, with enough sunshine overall to help boost temps to forecast afternoon highs. In general, the forecast looks on track through the remainder of the day, with no significant updates anticipated.

SHORT TERM
Issued 411 PM CDT Fri Mar 29 2024
Today through Sunday night:
A fairly mild day is expected away from Lake MI as high pressure slowly moves away. There will be intermittent cloudiness over south central WI via mid to upper level warm advection. A shortwave trough and sfc low will then approach from the central Great Plains for tnt. The sfc low will track to the srn tip of Lake MI by 12Z Sat, but preceded by 850-700 mb warm, moist advection and frontogenesis, and supported aloft by PVA. PWs will increase to 0.80-1.00 inches with very marginal elevated CAPE present on fcst soundings. Thus expect isold to scattered storms with widespread showers.
The low will move away Sat AM but a few showers could linger over east central WI. Stratus clouds are expected to last through much of the day as subsidence and drying is minor. More rain may then develop for Sunday as a weak 700 mb shortwave trough helps tighten up the confluent flow and tropospheric temp gradient between nrn and srn streams. Warm advection and frontogenesis at 700 mb will probably provide enough lift to overcome drier lower layers. Rain chances increase to 60-70 percent later in the day.

Monday through Thursday:
The zonal flow that set up over the Midwest and Northeast over the weekend will break down as a trough advances from the desert southwest. As the trough in the desert southwest advances northeast Monday, a second trough/shortwave is expected to descend from northwest Canada. As these two features begin to intersect over the Great Lake Region, Monday into Tuesday there will be some phasing issues to keep a close eye on. Looking at 500mb deterministic runs of the GFS, Euro and Canadian for Monday, all of them seem to be very similar with some upper level jet dynamics working into the state from the positively tilted trough in the desert southwest. Then as the second trough moves down from Canada and begins to phase with the southern system, that better upper level jet dynamics gets pulled south of the state. The ensembles seem to mostly cluster around these solutions as well, which is unusual for a system this far out. One noticeable difference as you start to look lower in the atmosphere (850 mb to the surface)
is the GFS seems to slow down and strengthen the system more than the Euro and Canadian.
With the better upper level support Monday and the surface low pressure system expected to pass just to the south of the state (with the current model agreement). POPs are at there highest during the day Monday (around 60-80%) before lowering as this system pulls east and the better upper level support shifts out of southern Wisconsin. Guidance continues to strengthen this system as it moves east into Michigan. On the backside of the low, Tuesday, there is a small chance (30% or less) for continued precipitation until the lift has moved out of the region.
Now looking at this system as a whole there is still some details to parse out. Namely the strength of this system and potential phasing issues between the northern and southern 500 mb troughs.
Any phasing issues that creep back into the solution or any moderating of this systems strength will likely cause the entire system to shift east and south overtime. So those will be two things to keep an eye on moving forward. There is also a potential for some rain/snow mix on the backside of this system Monday night into Tuesday. Given the decreasing lift and cooler air expected to move in confidence is low (around 25% or less) for mixy precip to develop due to overnight lows struggling to reach freezing across much of southern Wisconsin. If any mixed precip were to develop confidence is very low on anything actually accumulating.
By mid week, a ridge and surface high pressure look to make a return. Dry conditions look to be in store for Wednesday and Thursday. Temperatures look to warm through midweek as well.

Quiet weather is expected today, with periods of mid and high level clouds through the day. Showers are expected to develop by mid to late evening, with widespread showers then expected overnight. Still looks like a rumble or two of thunder will be possible, particularly towards the WI/IL border. Much lower ceilings are expected with the showers and behind the cold front overnight into Saturday, likely dropping to around 500 feet by daybreak. Ceilings should gradually improve from southwest to northeast Saturday afternoon into the evening. Light and variable winds this morning will become east to southeast by this afternoon, backing to northwest Saturday morning behind the departing low pressure system.

High pressure of 30.1 inches will gradually move across Lake Michigan today bringing light and variable winds. East winds will increase tonight ahead of approaching low pressure of 29.6 inches. The low will move across the far southern part of the lake Saturday morning, then winds will become northerly with gusts around 20 knots. Low pressure of 29.5 will move from the central Great Plains to the lower Great Lakes from Monday into Wednesday. Brisk north to northeast winds will dominate through Tuesday before becoming northwest. Gusts may approach 30 knots at times with building waves. Small Craft Advisories may be needed from Sheboygan to Winthrop Harbor from Monday into Wednesday.
