UPDATE

Issued 609 AM CST Sun Feb 8 2026

Cloudy conditions will continue throughout much of today, with any lingering flurries near Lake Michigan tapering off around sunrise. Expecting southeasterly winds to bring in a warmer airmass, especially for southwestern Wisconsin. Highs in the mid-30s are expected in southwestern Wisconsin while highs in the upper 20s are expected in southeastern Wisconsin where Lake Michigan will keep things cooler.

SHORT TERM

Issued 1240 AM CST Sun Feb 8 2026

Today and Tonight:

The strong mid level Fgen band is slowly moving east across the state early this morning. This line currently stretches from Fond du lac to Waukesha to Burlington and be over Lake Michigan over the next couple of hours. Under this band snowfall rates of 0.5 inches per hour are expected. With the good moisture profile in the dendritic growth zone there, there will be some picturesque flakes under the banding. Since this is a quick moving system, snow totals are likely to be around an inch or less. Areas in eastern and southeastern Wisconsin are the most likely areas to see an inch of snow if the forward progression stagnates a bit.

The upper level trough and 700 mb Fgen will move east out the area before day break and the sfc high pressure will take over keeping conditions dry. Southerly winds that set up today will help kick start WAA that will bring temperatures above normal through the rest of the week.

LONG TERM

Issued 1240 AM CST Sun Feb 8 2026

Monday through Saturday:

The upper level trough that will be moving down from Saskatchewan will be in southern Ontario/Northern Great Lakes Tuesday with the upper level jet overhead. This low pressure system looks to slowly strengthen and then eventually occlude as it in. The sfc occluded front looks to pass through Wisconsin late Monday night into Tuesday morning. There will be a slight push of cooler air, but all in all this looks like a dry frontal passage for southern Wisconsin. Moisture is just too low in the mid and lower levels to even squeeze out flurries. If you are looking for snow, looking further north or south will provide better results. Thursday into Thursday night looks to be the better time for any precipitation despite the fact that upper level cyclonic flow will remain to our north starting Tuesday. A few shortwave troughs look to move through the flow and provide another good push of lift/PVA Thursday. The big player here will be the available moisture. There is some big discrepancies in timing and location of the incoming snow Thursday so POPs remain low around 10-30%. As it stands now the best potential for snow looks to be for locations south and west of Madison.

High pressure and ridging begin to build back into the Great Lakes Region for late Thursday through Friday which would lead to dry and quiet conditions again. Additionally above average temperatures look to persist through the extended. Tuesday looks to be the warmest day of the week with temperatures in the upper 30s to mid 40s.

AVIATION

Issued 609 AM CST Sun Feb 8 2026

VFR conditions are observed across the majority of southern Wisconsin. However, lake effect clouds are streaming inland from Lake Michigan this morning under ESE winds and are bringing occasional drops in ceilings to around 1000 ft inland, and consistent MVFR conditions at Lake Michigan terminals. Expecting these clouds to lift to MVFR at 2500-3000 ft by midday and end across ENW/MSN as winds shift to SE during the same timeframe. MVFR ceilings are expected to continue at MKE and SBM, and perhaps as far inland as UES, throughout the day. Winds will shift southerly overnight tonight, with ceilings lifting to VFR by Monday morning as winds shift to become southeasterly and push any lingering lake effect clouds back out over Lake Michigan.

MARINE

Issued 1240 AM CST Sun Feb 8 2026

As high pressure around 30.4 inches is slowly moving from the far southern end of the Lake into the central Ohio River Valley tonight into Sunday. Modest south to southeast winds expected tonight through Sunday then winds will become south to southwest Monday as low pressure around 29.7 inches moves across Ontario. Southwest winds remain through Monday night. Then as the low pressure system in Ontario continues east, a trailing cold front will then pass across the lake Tuesday morning. Modest west to northwest winds are expected behind the front and will persist into the middle of the week.
