- Warming Back Up with Multiple Chances for Rain

DISCUSSION

- Colder, Quick Round of Light Snow Tonight

Temperatures have fallen behind the front and will drop into the 20s this morning. Highs today will only be in the 30s with some spots hitting 40. Tonight temperatures fall into the teens and 20s and then rise into the upper 30s to mid 40s for Saturday.

With the colder temperatures snow chances return. The shortwave trough currently over North Dakota will move in during the late afternoon/early evening toward Ludington and exit the area late tonight. This is currently causing some light snow to fall in North Dakota and expect the same to occur here. Snow/flurries could make it as far south as the I-94 corridor, but higher confidence will be along and north of I-96. A dusting of snow is possible with areas north of US-10 potentially seeing around a half inch. Probabilities of an inch or more are low (less than 20 percent).

- Warming Back Up with Multiple Chances for Rain

As mentioned in previous discussions, the long range ensembles show an active pattern next week. We switch to more troughing to the west and ridging to the east across the CONUS. Chances for rain increase Monday night within the southwest flow and warm air advection. A series of shortwave troughs will move through bringing chances (40 to 70 percent) for rain and thunderstorms Monday night through Thursday night. Cluster analysis shows some variations in timing and strength of the troughs as they move through along with surface low placement. Probabilities of an inch or more of rain over a 24 hour period are low (20 percent), but multiple days of rain may add up to 1.5 to 2.5 inches across the area as shown by the WPC precipitation forecast.

AVIATION /18Z TAFS THROUGH 18Z SATURDAY/

Issued at 152 PM EDT Fri Mar 27 2026

Cu is beginning to thin across the region, but some light precipitation over Wisconsin may clip the northern terminals this evening. The short wave driving this precipitation is moisture starved, so we're not expecting much more than a dusting, Then VFR conditions will prevail overnight.

MARINE

Issued at 230 AM EDT Fri Mar 27 2026

Small Craft Advisory conditions continue due to winds and waves. Winds will subside this morning, but 4 foot waves linger north of Whitehall and south of South Haven. Adjustments to the Small Craft Advisory may be needed for these areas.

Northwest winds pick up tonight and may bring a period of Small Craft Advisory conditions late tonight into early Saturday morning. Winds become southwesterly Saturday with warming temperatures. There is a chance for winds and waves to hit Small Craft Advisory criteria late Saturday afternoon into Sunday.
