- Hot and humid conditions expected today through Wednesday, with temperatures and heat index values in the 90s. The highest temperatures and heat index values are expected this afternoon.

- Isolated to scattered thunderstorms are possible this afternoon, with the strongest storms capable of producing gusty winds and small hail.

- There will be daily thunderstorm chances through the week due to warm and humid conditions.

- Dangerous swim conditions are possible Tuesday afternoon at Lake Michigan beaches in Sheboygan and Ozaukee Counties.

Issued 409 AM CDT Mon Jun 17 2024

Today through Tuesday:

Strong thermal ridging in the southeastern U.S. combined with a deepening surface low in the lee of the Colorado Rockies will continue to push hot, humid air into southern Wisconsin today through Tuesday. This air mass not only will produce high heat index values in the mid to upper 90s, but also brings chances for thunderstorms today and Tuesday.

Temperatures will climb quickly this morning as cloud cover remains minimal and southwesterly winds increase, reaching highs in the 90s across much of southern Wisconsin.
Southwesterly winds and downsloping off the Kettle Moraine will allow even areas near Lake Michigan to see temperatures in the upper 80s to near 90 degrees.

During the afternoon hours today, isolated to scattered thunderstorms are possible as surface temperatures rise to near convective temperature. A well mixed boundary layer and deep WAA combined with CAPE values over 2000 J/kg are expected to yield a few afternoon thunderstorms, with outflows leading to additional potential development. Bulk shear values of 20 kt or less are expected, making organization minimal for any developing cells.
In addition, WAA aloft is expected to keep midlevel lapse rates on the lower side and prevent large hail formation. Main concern then turns to gusty winds within stronger storms, with DCAPE values over 1000 J/kg and PWAT values around 1.5 inch lending credence to precipitation loading and corresponding downburst potential. The best chances for thunderstorm development are from Sauk to Ozaukee County northward, as this is along the southern side of a decaying MCS. However, the environment remains primed across all of southern Wisconsin.

Tuesday, hot and humid conditions continue, but thunderstorm activity looks to be more conditional. 850 mb WAA and moisture convergence may fire a few thunderstorms across southeastern Wisconsin during the afternoon hours, but confidence is lower due to a lack of significant trigger. Southerly winds and cloud cover may keep areas near Lake Michigan slightly cooler on Tuesday.


Issued 409 AM CDT Mon Jun 17 2024

Tuesday night through Sunday:

Low pressure lifts northward into Ontario by Tuesday night, with persistent thermal ridging over the Southeast U.S. keeping southern Wisconsin in primarily dry conditions through Tuesday night. As surface low pressure skirts the northern edge of the ridge into Wednesday, precipitation chances increase along a trailing frontal feature. Thunderstorm chances remain through the end of the week and into the weekend as a tropical disturbance in the Gulf of Mexico feeds moisture into the stalled boundary by way of the central Plains. Thermal ridging in the Southeast looks to become reinforced within a region of broad subsidence, preventing the boundary from propagating farther south. Uncertainty remains with the exact placement of the stalled boundary and therefore with timing and intensity of precipitation, but general cloudiness is expected to keep temperatures in the 80s from midweek onward.


Issued 409 AM CDT Mon Jun 17 2024

Low level wind shear will continue to diminish into early this morning, giving way to southwesterly winds by sunrise. Expect gusts up to 20 kt during the afternoon hours, diminishing into the overnight hours near Lake Michigan. VFR conditions are expected throughout the day for all terminals in southern Wisconsin.

Isolated to scattered thunderstorms are possible this afternoon, with the strongest storms capable of producing gusty, erratic winds. Thunderstorm potential is greatest at SBM, although isolated storms are possible across all of southern Wisconsin.
Thunderstorm activity is expected to diminish into this evening.
Any visibility reductions are expected to be short-lived. With the isolated nature of thunderstorms, confidence is not high enough to include in TAFs as of this morning's update.


Issued 409 AM CDT Mon Jun 17 2024

Modest southerly winds will prevail through tonight. Low pressure lifting from the northern Plains into northwestern Ontario on Tuesday will then produce gusty southerly winds Tuesday through Tuesday night. Small Craft Advisory conditions are possible due to high winds and waves on Tuesday. Light southwesterly winds are then expected as the low continues to lift into the Hudson Bay, with a cold front slowly pushing southward across the lake Wednesday night into Thursday, shifting winds northeasterly.

Periods of thunderstorms are expected this afternoon, with slight chances on Tuesday morning. A few stronger thunderstorms may produce gusty winds this afternoon. Slight chances are expected again Tuesday afternoon across the southern half. Thunderstorms become more likely on Wednesday into Wednesday night across the open waters.
