Today through Sunday:

Upper-level ridge builds across the Upper Midwest today into Saturday bringing unseasonable warm temps. Continue to see higher probabilities (>60%) from 00z HRRR as well as NBM and GEFS, for afternoon high temps to exceed 60F for much of southern WI today. Tonight will be mild as well with lows in the mid 40s to even low 50s given some help by cloud insulating the area.

Warm temps linger into Saturday, but upper-level ridge axis does kick east as a trough begins to dig down toward the Upper Midwest. Accompanying this trough will be a cold front extending south from a surface low trekking across the Hudson Bay region.
Mid-range models agree on a the cold front passing through southern WI through late morning/early afternoon bringing a westerly wind shift by the evening. While most models keep the frontal passage dry for southern WI as any moisture will contend with a stout dry-layer, still cannot rule out some scattered light shower activity given PWATS approaching an inch (0.7-0.9 inches) along with forcing from the front paired with a ripple of mid-level vorticity. If anything does develop, do not expect much accumulation from this and would range from a trace to under a tenth of an inch. Otherwise, the colder airmass will be delayed behind the frontal passage, thus could see temps 50s and 60s high temps again through the first half of the day, while temps look to dip overnight Saturday with lows back into the upper 20s and mid 30s.

The colder airmass will settle in across southern WI for Sunday with the prevailing upper-level northwesterly flow. Temps return to normal with highs back into 40s and lows into the 30s.

Monday through Thursday:

Not much of a change when looking at the start of the work week.
Troughing in the eastern CONUS and a ridge across the central CONUS with multiple shortwaves in the flow will be our starting point for Monday. Guidance has come into better agreement after a couple runs and has a shortwave passing just to our south Monday late afternoon into Monday night. The sfc low looks to move from the Central Plains and into the Ohio River Valley which will keep Wisconsin on the northern side in a stratiform precipitation region. Due to the current path however most of the precipitation looks to pass to our south. Far southern Wisconsin has the best chances for precip around 30 to 40%. The CAN pushes the precip the furthest north bringing some precip as far north as the I-94 corridor while the GFS is the other extreme keeping southern Wisconsin largely dry. Deterministic and ensemble guidance are waffling a bit on whether or not to give the forecast area precip. The EURO has the most ensemble members that bring us rain/snow. Given this, POPs may fluctuate a bit yet with the best chances for rain being far southwestern and southern Wisconsin.
QPF amounts will be really low since the state is on the northern fringe of the low resulting in light showers at most. Now, normally being on the north side of the low this time of year brings a risk for snow, but that confidence on this is even lower than the POPs. Its likely that showers will start as rain and as time progress into the overnight hours there could be a change over to snow. Timing doesnt match up well with this as most models, apart from a few Euro runs, have the precip ending before a change over could start. So while possible any snow we get will be flurries with little to no accumulations.

Beyond this low chance for rain Monday late afternoon through Monday night, high pressure will descend from Canada for Tuesday and Wednesday. Dry and quiet conditions are expected with temperatures near normal (highs in the 40s and overnight lows in the low 30s to upper 20s).

Thursday into Friday looks to be our next chance for measurable precipitation. There is still quiet a bit of uncertainty for this, but this looks to be another chance for potentially phasing systems. A trough in Canada looks to descend into the Great Lakes Region while a second trough in the Desert Southwest advects northeast. Depending on the model you look at the timings vary wildly and the strengths of each trough do too. So expect a lot of things to change here.

VFR conditions will prevail through the period as a cold front begins to dig down across the Upper Midwest. Looking at southerly winds around to below 10kt today and easing tonight. However, expect a period of low level wind shear overnight.Then breezy southwesterly winds (10-15 kt) are expected into Saturday before the cold front pushes through southern WI late morning/early afternoon bringing gusty (15-20 kt) west- northwesterly wind shift trough the afternoon.

Expect moderate southerly winds to build across Lake Michigan today as high pressure over the southeastern US continues to slide southeastward. Winds begin to shift to the southwest into Saturday as a secondary low pressure tracks across the Upper Great Lakes. This will also drag a cold front across the region through the day Saturday with west to northwesterly winds increasing across Lake Michigan into Sunday. Winds gusts will approach gale force during this timeframe, especially for northeastern nearshore zones in the far northern third of the lake Saturday night into Sunday. While potential for gales persist, still a bit of uncertainty on exceeding 34 knots for extended period. Thus will to hold off on any gale headlines at this time. Winds then look to diminish into the start of next week as high pressure builds into the Upper Midwest.
