Short Term...Tonight and Thursday

Main forecast concern remains on precipitation trends over the next 24 hours as a frontal boundary to linger to our south and a shortwave moves into northern sections of the Great Lakes.

The 19Z MSAS surface analysis showed a cold front that extended from roughly MNM-Y50-DBQ. High pressure was situated over northern sections of the northern Plains/Upper MS Valley. The radar mosaic indicated scattered showers and thunderstorms across the southeast half of WI ahead of the cold front where sufficient instability and shear present.

The cold front is forecast to move across the rest of east-central Wisconsin this evening and then stall near the IL border later tonight. The proximity of the front is close enough such that a chance of showers and thunderstorms will need to be kept in the forecast across parts of central and east-central WI, mainly south of Hwy 54. Meanwhile, the high pressure will move into northern sections of the Great Lakes and keep northern WI dry tonight.
Cooler/less humid air mass to settle over northeast WI tonight with min temperatures to range from the lower to middle 50s north, to the upper 50s to lower 60s south.

Models hint at this stalled boundary will begin to slowly lift back north as a warm front on Thursday, but remain south of the forecast area. A mid-level shortwave is expected to move northeast into the western Great Lakes in the afternoon. Between these two features, the chance for showers and thunderstorms will be on the increase, mainly during the afternoon. The combination of clouds, precipitation chances and an east-northeast wind will keep temperatures below normal on Thursday. Look for readings to only reach the upper 60s to lower 70s.

Long Term...Thursday Night Through Wednesday

Despite high pressure over the northern Great Lakes region, isentropic lift north of a warm front over the southern Great Lakes will bring the chance for showers and thunderstorms to the region Thursday night. This warm front will then lift north on Friday into southern Wisconsin, with increased chances for precipitation across the region. Although there will be modest instability of a few hundred J/kg of MUCAPE, the best instability will be well to our south along with the severe weather risk.
However, heavy rainfall and some minor flooding will be a risk with long skinny CAPE profiles and PWAT values of 1.75 to 2 inches.

The warm front will linger across Wisconsin Friday night and Saturday, with additional chances for moderate to heavy rainfall.
Instability will remain fairly meager across our area, keeping the severe weather threat minimal. However, the continued threat for several rounds of rainfall will increase the flood threat as repeated rounds of moderate to heavy rain cause rivers and streams to rise to or near bankfull.

The region is in a slight risk for excessive rainfall Friday and Saturday. Probabilistic guidance indicates there is a 30 to 40 percent chance of exceeding 2 inches of rain Friday and Saturday, with the highest chances across central and north-central Wisconsin.

A cold front will then sweep through the area Saturday night, which will end the threat for moderate to heavy rain across the region. Although additional light showers are possible on Sunday, this activity is not expected to exacerbate the flooding threat like the previous activity.

Next week will start out dry, with additional chances for rain Tuesday and next Wednesday as several weak low pressure systems track through the area. Next week will bring a return to warmer weather as daytime highs soar into the 80s with a few 90 degree readings possible, especially across central and east-central Wisconsin.

for 06Z TAF Issuance Issued at 1045 PM CDT Wed Jun 19 2024

Cold front has settled south and east of the area so stronger showers and thunderstorms have ended for the night. Still could be waves of lighter showers crossing the area at times overnight into Thursday with best chances late tonight into midday Thursday over east-central WI. At this point, it does not look like the showers on Thursday will be widespread. Meanwhile it will remain mostly dry at AUW/CWA/RHI until late Thursday afternoon as a warm front shifts in from the southwest and an upper disturbance crosses the northern plains.

Conditions will be mostly VFR this evening, but will trend MVFR overnight into much of Thursday at east-central WI terminals as a cooler/moist NE flow develops to the north of the front. Cigs will drop to IFR near the lakeshore at times with some fog as well, including at MTW. Cigs will improve to VFR late on Thursday.
