Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 325 PM CDT Tue Jun 18 2024


- Small chances (15 to 20 percent) for showers and storms in southern and southeastern parts of the area until early this evening.

- Better chances (30 to 60 percent) for showers and storms overnight into Wednesday night.

- Heat index values will be between 95 and 100 degrees until early this evening away from Lake Michigan.

- Dangerous swim conditions are likely into tonight at Lake Michigan beaches in Sheboygan and Ozaukee Counties.

Issued 324 PM CDT Tue Jun 18 2024

Tonight through Wednesday night:

The low clouds have scattered out across the area, allowing for the very warm and humid conditions to take hold. Heat index values in the middle to upper 90s are generally expected inland from Lake Michigan until early this evening. A southeast lake breeze has developed near the lake, and those areas will cool down as a result.

Peak temperatures will be close to convective temperatures, especially toward the Illinois border area. Isolated to widely scattered pop up showers and storms are still possible to occur in these areas. There is enough mean layer CAPE to possibly bring gusty winds with any storms. Deep layer bulk shear is quite weak, around 15 knots or less. So, would expect any showers and storms to be fairly short-lived.

Beach Hazards Statement remains in effect until later tonight for the Sheboygan and Ozaukee County beaches. Gusty south winds will bring waves up to 4 feet for these beach areas, which will result in dangerous conditions for being in the water. A moderate swim risk remains for beaches to the south of there as well.

There are better chances for showers and storms (30 to 60 percent) overnight into Wednesday night, as a cold front sags southeast into the area and washes out. There are some indications from the CAMs that the cold front could shift south of the area as well by Wednesday evening.

Generally weakening showers and storms from the west overnight may shift into the western parts of the area. This may linger into Wednesday morning. CAMs generally support the weakening trend with this overnight and early morning activity.

Clouds associated with this activity may linger through the rest of Wednesday, so there is uncertainty with how much instability will be available for possible storms later Wednesday into Wednesday evening. Deep layer bulk shear is expected to increase to 25 to 35 knots Wednesday afternoon and evening, so if storms can develop, there is some risk for strong winds from downbursts to occur. This will be conditional on clouds scattering out and enough instability developing.

Heat index values may still reach the middle to upper 90s in far southeast Wisconsin, where the most sunshine could occur.
Again, this will depend on if the clouds can scatter out by the afternoon.


Issued 324 PM CDT Tue Jun 18 2024

Thursday through Tuesday:

The upper flow will transition to nearly zonal between Wednesday night and Thursday as high pressure settles over the southeast US. Weak ripples in the flow will roll across southern WI and northern IL at times through Saturday. The effective front will waffle north and south a little, but overall we will remain in a warm and unstable pattern with at least small chances for showers and thunderstorms through the period. It looks like a stronger wave will cross the region Saturday and drag a weak cold front through southern WI Saturday afternoon or evening. This is a more certain time for storms, but the time of day will determine their severity so this is something to keep an eye on.

There will be a brief period of northwest flow and a relief from the warm temps and storms Sunday into Monday night, but it looks like we will be warm again by Tuesday.


Issued 324 PM CDT Tue Jun 18 2024

Low clouds have scattered out and any ceilings have risen above 3500 feet AGL. South winds will continue to be gusty this afternoon, before weakening somewhat tonight. A southeast lake breeze has developed and has shifted the gusty winds southeast at Milwaukee. These winds may vary from south southeast to south southwest at this location, if the lake breeze boundary gets pushed back to the east.

There should be low level wind shear conditions tonight, with southwest winds around 2000 feet AGL of 40 to 45 knots.

A few showers and storms may pop up until early this evening.
Weakening showers and storms should move into areas west of Madison overnight, and may spread over the area into Wednesday morning.

Low clouds with ceilings of 1500 to 2500 feet AGL may spread over the area during this time, and may linger into the rest of Wednesday and into Wednesday night. There may be more showers and storms that form along a weakening and stalling cold front Wednesday afternoon and evening, but it is still uncertain how much of this activity will occur at this time.


Issued 324 PM CDT Tue Jun 18 2024

Low pressure around 29.5 inches will move from west central Minnesota to near James Bay tonight. Gusty south winds are expected to linger tonight into early Wednesday.

A Small Craft Advisory remains in effect through this evening for the nearshore waters, with the gusty winds and building waves. Gusts over the open waters will reach 30 knots at times into tonight, mainly over the northern portions of the lake.

Some fog may develop at times over the lake into Wednesday, with the very warm and humid airmass in place.

Winds will gradually ease Wednesday and shift to the north by Wednesday evening, as a cold front sags into the region. North to northeast winds should then linger into Thursday night, as high pressure around 30.4 inches moves into Lake Superior.
