UPDATE. (Issued 905 AM CDT Thu Jul 29 2021)

Made just some minor tweeks for cloud cover trends.

SHORT TERM. (Issued 454 AM CDT Thu Jul 29 2021)

Today through Friday:

The thunderstorms and heavy rainfall over Lafayette and Green Counties will shift swd into IL over the next hour or two. This coincides with the wly low level jet shifting south as the cold front approaches from the north. The high clouds and some stratus this morning will then transition to partly cloudy skies for the afternoon. Nly winds and gradual cold advection will continue through the day into tonight. Thus temps will be cooler on Friday versus today. High pressure will move across srn WI Friday afternoon.

Gehring

LONG TERM. (Issued 454 AM CDT Thu Jul 29 2021)

Friday night through Wednesday:

The high will shift south of the area for Fri nt and Sat while weak low pressure moves from the nrn Great Lakes to the Lower Great Lakes for the weekend. Thus swly winds and warmer temps will return for Sat, but also with chances for showers and storms with the cold frontal passage in the afternoon and early evening.

High pressure and pleasant temps will then prevail for early next week as nly flow aloft continues.

Gehring

AVIATION. (Issued 905 AM CDT Thu Jul 29 2021)

High pressure will gradually take over the region. Extensive cloud cover with some MVFR cigs continue to cover much of the area but these will gradually exit and mix out a bit as the remainder of the morning wears on. However with low level thermal troughing in place some additional CU redevelopment is plausible. Northwest winds will become more northerly and eventually northeast this afternoon into tonight.

MARINE. (Issued 454 AM CDT Thu Jul 29 2021)

A cold front will move south across Lake Michigan this morning. Breezy north winds are expected and will last through tonight. High pressure of 30.1 inches will then move across the lake Friday afternoon. The high will move south while weak low pressure tracks from the northern Great Lakes to the Lower Great Lakes for the weekend. Modest southwest winds will develop over Lake Michigan for Friday night into Saturday, followed by another cold front bringing breezy northerly winds for Saturday night and Sunday. A Small Craft Advisory is in effect from Sheboygan to Winthrop Harbor from 10 PM tonight until 10 AM Friday for persistent north to northeast winds and waves building to 3 to 5 feet.

Gehring

BEACHES. (Issued 454 AM CDT Thu Jul 29 2021)

There is a high swim risk tonight for the Lake Michigan beaches from Sheboygan County south to Kenosha County due to north to northeast winds and waves of 3 to 5 feet. A Beach Hazard Statement may be issued later today.
