- Rain Showers End Early With Breezy Conditions Today
The current rain shield associated with a surface low progressing northeast across the Central Great Lakes will exit the area by 12z with drier air expected behind it. Most of the area will be mostly sunny today, however late this afternoon some moisture in the 850- 700mb layer approaches areas north of M20 bringing a cloud deck that will cross the area overnight.
One thing to watch today will be RH values, especially across southern Michigan. Given the lighter nature of QPF tonight, some guidance like the HRRR is trending towards lower minimum RH values towards 30 percent this afternoon. If we can mix towards lower RH values, breezy conditions with winds gusting 20-30 mph may lead to a window of elevated fire weather concerns.
- Temperatures Fall Near Freezing Friday Night
Given the recent stretch of warmer weather, vegetation is starting to become vulnerable to freezing temperatures. As troughing sets in over the area and cold air advection begins, overnight temperatures fall into the low to mid 30s. However, surface winds likely won't die off into the overnight hours thanks to a gradient associated with a surface high to our west.This may keep enough mixing to avoid a sharp near-ground temperature inversion.
Saturday then features partly cloudy skies becoming mostly sunny during the afternoon. Continuing cold air advection will keep highs in the 40s.
- Below Freezing lows for the Sun to Mon
The northwest flow continues Saturday night into Sunday keeping any significant warming away from the region. The flow then backs to the west southwest for Sunday night into Monday. Cooler than normal temperatures will continue given this pattern. Ensemble temperature forecasts continue to support surface temps going below freezing at night, especially for inland locations. No noticeable trends were seen in the latest runs. We will therefore maintain the current forecasts showing a potential for subfreezing temps both nights. The wind will likely not go calm for Saturday night, but later Sunday night the wind will likely be lighter. So some frost my occur then.
- Potential for a few storms Tuesday
Models are tracking the next wave of low pressure eastward through northern parts of Lower MI Tuesday. The GFS does draw up enough instability to warrant a few thunderstorms. The Canadian and ECMWF are more conservative with the instability but do show a similar track, with southwest winds over the CWA on Tuesday. We will therefore feature a chance for thunderstorms for southern parts of the CWA ahead of the frontal passage. Bulk shear values through 500 mb are shown to be strong with steeper mid level lapse rates so trends will need to be monitored closely.

Issued at 734 AM EDT Fri Apr 19 2024
The area of light rain and low level moisture east of KLAN will continue to push eastward over the next hour or two leading to conditions become VFR for Southwest Lower MI. Gusty west to northwest winds will develop as the mixing height increases and leads to the gusty conditions. Some VFR clouds will start to move back in later in the day and the winds will diminish slightly by sunset.
MARINE
Issued at 246 AM EDT Fri Apr 19 2024
Winds and waves will build over the coming hours resulting in conditions hazardous to small craft today. Going small craft advisory for all nearshore waters between St. Joseph and Manistee through 8pm looks to be in good shape. A brief lull in winds and waves, mainly Holland and points south, is possible this evening before winds and waves increase again into Saturday. The small craft advisory likely will need to be extended into Saturday to cover this second surge in winds and waves.
