(Issued 250 PM CST Fri Dec 8 2023)

Tonight and Saturday:

After an unseasonably warm end to the week, our sunshine will give way to rain. Overnight, a dynamic low pressure system will propagate northeastward and latch on to a larger trough currently towards our northwest. As this low traverses northeastward, rain will begin overnight heading into the morning. Values of rain will be greater along south-central to eastern Wisconsin, with probabilities hovering around 80% for .5 inches along an axis extending from the Wisconsin/Illinois border towards Sheboygan.

Gusty southwest winds and clearer skies will follow the passage of this system as it continues to retreat towards the northeast.
Anticipate cooler temperatures, with higher temperatures remaining near the upper 40s by the lakeshore.


(Issued 250 PM CST Fri Dec 8 2023)

Saturday night through Friday:

Dry slot that persists through most of Saturday pushes out by Saturday night and the secondary surface low deepens and lifts northeast. There looks to be enough moisture on the backside of the departing low for a few scattered, more cellular showers Saturday night. This will align with the colder airmass and result in mostly snow. Given the overnight timing and colder airmass, impacts will be limited, but may be enough to accumulative on untreated roadways especially with any brief bursts of heavier snow.

Otherwise, the extended forecast from Sunday onward is looking fairly less active with upper level ridging and a series of surface high pressures dominating the forecast. Temps will be cooler and closer to normal, but may trend warmer toward the later half of next week.


(Issued 250 PM CST Fri Dec 8 2023)

Southwest winds continue to remain gusty with high altitude clouds overhead. Overnight, winds will calm variable as rain enters the area around 4Z. Low ceilings and visibility are anticipated in areas with heavier rain, approaching LIFR. After rain moves out of the area, winds will pick back up, and remain gusty southwest around 15 kts.


(Issued 250 PM CST Fri Dec 8 2023)

South winds up to 15-20 knots will continue as low pressure around 29.3 inches gradually moves east over Ontario. A secondary area of low pressure currently over Oklahoma will drift northeast over south central Wisconsin tonight and advance over Lake Michigan early morning Saturday. Winds will shift west/southwest and become brisk by late Saturday morning. A cold frontal passage Saturday night will shift the winds to brisk northwesterly that will last through Sunday.
