SHORT TERM
Issued 135 PM CDT Tue May 20 2025

Tonight through Wednesday night:

Low pressure will continue to approach from the southwest this afternoon and evening, slowly sliding by just to the south of Wisconsin tonight into Wednesday. Widespread rainfall will come to an end across the northeast forecast area by mid/late afternoon. Meanwhile, showers will move in from the southwest this afternoon, with periods of showers likely though Wednesday as the low lingers in the region. There could be a little thunder this afternoon and early evening, mainly along/south of I-94 as a ribbon of instability sneaks into southern Wisconsin.

While the bulk of expected precipitation totals with this event will wind down with the end of the widespread rainfall, pockets of 0.5"+ will still be possible tonight into Wednesday.
Precipitable water values around 1.25" will gradually decrease tonight through Wed, down to around 0.75"-1.00" by tomorrow afternoon. Overall forcing will be less tonight into Wed as well, though the lingering moisture and some mid-level frontogenesis should keep the showers going with the low nearby.

Temperatures will hold fairly steady over the next 36 hours with the persistent clouds and showers, only ranging from the mid 40s at night to the upper 40s and low 50s during the day.

LONG TERM
Issued 135 PM CDT Tue May 20 2025

Thursday through Tuesday:

A broad troughing pattern will persist across the Great Lakes Thursday and Friday. It looks dry much of this time, though wouldn't be surprised by a few sprinkles or showers at some point if a weak wave rolls through the northwest flow. Could see some sunshine poke at at times Thu and Fri, though this pattern should result in a fair amount of cloudiness through the end of the week. Below normal temps will continue through Friday.

The upper level pattern should shift more to weak ridging pushing in from the west over the weekend. Surface high pressure will be in place, which should result in dry weather. Could see some more sunshine under the high, though latest models are trending cloudier at the mid and high levels. This setup should allow temperatures to recover some, though highs will likely remain below normal through the weekend.

A trough is expected to approach or move through the area early next week, bringing a chance for rain showers back to southern Wisconsin. There is fair amount of uncertainty with the timing/strength/placement of this system, with plenty of time for the finer details to get worked out, as this system is nearly a week out.

MARINE
Issued 135 PM CDT Tue May 20 2025

Breezy easterly winds will continue this afternoon into tonight, becoming northerly by Wednesday afternoon as low pressure of 29.5 inches travels from eastern Iowa to the eastern Great Lakes. A few gales will likely persist into late afternoon in the south, with winds then still gusting to around 30 knots this evening into tonight. A Gale Warning remains in effect until 21Z over roughly the southern 1/3 of the lake, including the nearshore waters south of Port Washington.

Breezy northerly winds will continue on Thursday as the low stalls over the eastern Great Lakes, while high pressure of 30.2 inches approaches from the west. A Small Craft Advisory is in effect into Thursday due to the lingering higher winds and waves. Lighter winds are likely by the weekend as the high moves overhead.
