- Windy With Morning Showers Monday
Isolated showers and storms have developed over the region this morning with more widespread precipitation and scattered storms arriving shortly. A low pressure system moving into Wisconsin today is the driver of our precipitation, with a cold front crossing the area this morning bringing the more widespread precipitation. Satellite shows a pronounced dry slot behind this front that will keep the afternoon dry. Increased mixing behind the front will lead to 30 to 40 mph gusts Monday as well.
- Several Chances For Showers Mid to Late Week
Our next chance of rain is Tuesday Night into Wednesday as we see a warm frontal boundary lift north through lower Michigan. What follows is quasi-zonal flow with small embedded shortwaves. Periods of showers cannot be ruled out Wednesday/Thursday, but these setups feature low predictability so timing, occurrence, and placement of showers is not certain.
Rain chances increase again Thursday Night into Friday as a low pressure system moves into the midwest. This will bring the potential for both showers and thunderstorms into the region.
Conditions then dry out for the weekend as high pressure and ridging move into the Upper Great Lakes.
- Late Week Warmup Expected
Highs are expected to climb into the 60s through Wednesday and well into the 70s Thursday and Friday as ridging arrives. Some cooling is expected behind the late week system, but it only drop highs into the 60s for the weekend.

Issued at 721 AM EDT Mon Apr 21 2025
LLWS will continue through the morning with rain showers along a cold front pushing slowly east across Lower Michigan between about 14Z to 16Z. MVFR conditions can be expected much of today with ceilings from 1500 to 2500 ft AGL. VFR conditions should arrive during the evening as the stratus clouds scatter out. Winds will gust over 20 knots today then diminish later tonight.
MARINE
Issued at 243 AM EDT Mon Apr 21 2025
No changes to the going forecast this morning. Winds have increased ahead of a cold front with gusts of 25 to 30 knots ongoing. Better mixing behind the front will lead to a period of gales around 35 knots during the day today before winds fall tonight. A period of winds and waves hazardous to small craft are expected after the gale warning expires. Conditions subside below small craft advisory criteria by daybreak Tuesday and remain there through midweek as gradient winds weaken.
