DISCUSSION
Issued at 412 AM CDT Thu Jun 20 2024

Short Term
Today
Tonight...and Friday

The right entrance region of an upper jet was producing light rain showers across east central Wisconsin at 09 UTC this morning.
This jet will exit the forecast area this morning. Another jet streak will approach central and northcentral Wisconsin during the afternoon, and could produce scattered showers and isolated thunderstorms. A surface high centered over Lake Superior will bring a northeast flow of cooler air today with high temperatures five to ten degrees below average on the first day of summer.

There is a chance of a shower or thunderstorm tonight in association with weak upper support, but most areas will likely remain dry.
Cloud cover will limit how cool it will get, but temperatures should still drop to normal levels for this time of the year.

The likelihood of showers and thunderstorms will increase Friday ahead of a warm front moving north from the Illinois border.
There will be a lot of moisture in the atmosphere above the stable surface layer, so locally heavy rain is possible with the thunderstorms. Clouds, rain and an east northeast will make for a cool day with highs in the middle 60s to low 70s.

Long Term...Friday Night Through Wednesday

Main focus of the extended period will be the potential for heavy rain and stronger thunderstorms Saturday as a low pressure system moves across the region. Confidence in the flood risk is increasing, especially for low-laying and urban areas.

Friday Night through Saturday...Moderate to heavy rain will likely be ongoing Friday night with widespread isentropic ascent over the region as a warm front slowly lifts north. The heaviest band of rainfall fall Friday night into Saturday morning will likely be focused across northern WI along the noise of developing 30-40kt low- level jet. Periods of heavy rainfall are progged to continue into Saturday afternoon as models show a deepening low pressure system propagating across the Dakotas toward the Minnesota Arrowhead. The axis of heaviest rainfall during this period will likely be focused along the axis of greater frontogenetic lift which is currently forecast to develop generally along a line from east-central MN to central WI. In combination with the abundant lift, the expected heavy rain is the result of an anomalously moist air mass moving over the region. Medium range guidance is showing PWATS ranging from 2- 2.5 inches which is in the 99th percentile of the CFSR climatology database. In terms of total QPF Friday through Sunday, ensemble models are showing a 15-40 percent chance for greater than 2.5 inches of rain with the highest chances in central and north-central WI. Deterministic models are more bullish with the GFS, ECMWF, and Canadian all showing high end amounts of 3-4 inches.

There is more uncertainty with the severe weather potential Saturday, compared to the heavy rain potential. A few stronger discrete cells may develop over central WI Saturday morning, however the better chance for stronger to severe thunderstorms looks to come Saturday afternoon and evening as a cold front sweeps across the region. However, with relatively modest low and mid-level lapse rates forecast sounding show tall skinny CAPE profiles with MUCAPE values up to about 500 J/kg in central WI which is not necessarily an environment that would favor quickly accelerating updrafts. Effective shear values of 35-45 kts are expected along the cold front which could help to sustain any updrafts that are able to develop. If stronger storms are able to develop strong wind gusts and hail would likely be the main concern.

Sunday through Wednesday...Once the cold front passes through the region the risk for heavy rain will diminish, however, a few showers and storms may linger into Sunday as moisture wraps around around the departing low. Ensemble models then favor a high pressure system taking over Monday returning dry conditions to the region. The upper- level is then forecast to flatten out toward the middle of next week allowing a few chances for showers and storms to cross the area Tuesday and Wednesday. Temperatures are expected to start warming back up next week with highest on Tuesday expected to peak in the middle to upper 80s.

AVIATION
for 18Z TAF Issuance Issued at 1254 PM CDT Thu Jun 20 2024

MVFR/IFR ceilings are expected roughly south of Highway 29 early this afternoon, with scattered showers diminishing across east- central Wisconsin.

VFR conditions are likely this afternoon and evening as slightly drier air arrives thanks to a surface high over Lake Superior.
Rain and IFR conditions are likely over most of the region late tonight and Friday as a warm front approaches from the central Plains.

GRB WATCHES/WARNINGS/ADVISORIES
None.
