Area Forecast Discussion...UPDATED National Weather Service Milwaukee/Sullivan WI 1037 AM CDT Wed Jun 19 2024


- There will be chances for showers and thunderstorms this afternoon into this evening for all of southern Wisconsin. May see gusty winds with the stronger storms over southeast Wisconsin. On and off thunderstorm chances will then continue into this weekend.

- Heat index values will be in the middle 90s over southeast Wisconsin today. Head index values will be back in the middle 90s Friday and Saturday.

- A moderate swim risk may occur Thursday morning at Sheboygan County beaches.

Issued 1037 AM CDT Wed Jun 19 2024

Cold front is expected to continue to shift southeast into the area this afternoon and into northern Illinois tonight. CAMs are generally showing widely scattered to scattered showers and storms developing after 1 to 2 PM CDT this afternoon and continuing ahead of the front into at least early this evening.

The best instability will be toward southeast Wisconsin, where daytime heating should bring mean layer CAPE into the 1000 to 1500 J/kg range, perhaps higher in spots. Areas further northwest may have more clouds move in with the front, so mean layer CAPE there will be lower. 0 to 6 km bulk shear values are weak into early afternoon, perhaps 15 to 20 knots. They are expected to increase by later this afternoon and early evening into the 20 to 25 knot range, though the southeast parts of the area will be on the lower end of this range.

This would mean short-lived airmass thunderstorms that have some downburst wind potential, as forecast soundings are showing some inverted V structures to them in the low levels. Heat index values in the lower to middle 90s are expected in southeast Wisconsin, with highs in the upper 80s to lower 90s.


Issued 441 AM CDT Wed Jun 19 2024

Today through Thursday:

A cold front is expected to slowly sink southeast over the state today. Currently, a weak 500mb wave along the front is causing an area of shower and storm activity over NE IA. This activity should continue northeast into central WI this morning and fade with time. There should be a bit of a lull in activity as the front continues southeast, but by the mid afternoon, convergence along the front and the breaching of convective temps should allow for scattered thunderstorms to form over much of southern WI. Shear will be weak with effective bulk shear only around 10 knots, but shallow inverted v soundings in the lowest 1 to 2 km and PWATs in excess of 1.6 to 1.8 inches will cause torrential downpours and the possibility of downbursts with any storms that form.

Scattered shower and storm activity will continue into the overnight hours and into Thursday morning as the front slowly sags south and stalls in northern IL. Thursday will actually feel cool in comparison to the past few days, as cloud cover, rain and northeasterly flow off of Lake Michigan will dull daytime highs. Highs will be in the 70s over most of southern WI, with 80s near the WI/IL border. Dew points will remain elevated however, keeping some soupiness in the air.


Issued 441 AM CDT Wed Jun 19 2024

Thursday night through Tuesday:

Lee troughing along the Rockies is anticipated to create an area of low pressure over the Nebraska panhandle by Thursday night. WAA in association with circulation around this low will bring another surge of warmth north for Friday and Saturday with daytime highs in the mid to upper 80s for Friday and the upper 80s to low 90s for Saturday. Heat indices will reach the 90s both days owing to lingering dew points near 70. The broad WAA over the upper midwest to central plains is expected to promote further chances for convection Thursday night into Saturday morning with the NBM painting broad PoPs of 30 to 45% over southern WI.

Models are still keying in on a cold frontal passage Saturday evening with 60 to 70% PoPs as the aforementioned low deepens and approaches Lake Superior. Timing of the front would suggest some of the storms would be strong, but GFS soundings are currently ho-hum, with only 25 knots of effective bulk shear, mid level lapse rates around 6 C/km, 1600 J/kg of SBCAPE, and weak flow evident in the hodographs. This paired with boundary parallel shear would drive quick upscale growth into a squall line along the front Saturday night. We'll continue to monitor the storm threat as the weekend draws closer.

Beyond, temperatures "cool" in the low 80s Sunday and Monday as high pressure sink south into the area behind the front, but heat may return by Tuesday as ridging returns.


Issued 1037 AM CDT Wed Jun 19 2024

Gusty southwest winds this afternoon will shift west to northwest and weaken later this afternoon and early this evening, as a cold front moves southeast through the area.
Widely scattered to scattered showers and thunderstorms may develop with the front during the afternoon and early evening, and may bring gusty winds and locally reduced visibility values.

Light winds will shift north this evening and northeast later tonight, with east to northeast winds on Thursday. Cooler temperatures are expected tonight into Thursday, especially near Lake Michigan. A few showers and storms may occur at times overnight into Thursday, perhaps more toward the Illinois border areas on Thursday.

General VFR ceilings overnight should drop to 800 to 1500 feet AGL Thursday morning and slowly rise Thursday afternoon. In addition, fog with 2 to 5 mile visibility may form overnight into Thursday morning, or move onshore from Lake Michigan for terminals nearby. Locally lower values are possible.


Issued 415 AM CDT Wed Jun 19 2024

A cold front will gradually sink east-southeast over Lake Michigan through today as low pressure approaches James Bay in Canada. Modest southerly to southwesterly winds will prevail through today until winds come around to northerly tonight following the front. In the post-frontal air mass, some areas of marine fog may form tonight.

North to northeast winds should then linger into Thursday night, as high pressure moves toward Lake Superior.
