- Near to above normal temperatures continue this week
DISCUSSION

- Showers and Storms Continue into Sunday and Monday
A surface low ejecting out of the southern plains will carry a warm frontal boundary into lower Michigan today. This front will stall over central lower this afternoon keeping showers mainly north of I- 96. Though the bulk of the instability will be mainly south of the frontal boundary and convection, storms will be possible. Severe weather does not look likely. HRRR probability matched mean values continue to advertise local patches of 1 to 1.5 inches of rain from now to Monday morning, suggesting some training of storms may be possible.
The upper trough associated with the surface low to our west moves into Ontario providing better upper support for an approaching cold front. Widespread showers encompass the CWA Sunday night and Monday.
Storms will be possible as modest instability ahead of the front builds with bulk shear values up to 35 to 45 knots. Showers exit east late Monday leading to a dry Tuesday.
- Multiple chances for rain exist from Monday night and beyond
The upper system responsible for our chances for rain this weekend exits the Great Lakes into Canada Monday night. The rain will end Monday evening and we will be dry the remainder of the night and through Tuesday. A vort lobe pivots through the Great Lakes Tuesday night into Wednesday morning with another chance for rain. This chance for rain appears to be quite light as the upper system is located well west of the area.
Another active weather period looks to be Thursday into Saturday as an upper trough moves into and through the area. Showers and thunderstorms are both in the forecast during this time frame as surface dew points surge into the 60s F. Most unstable CAPE values reach the 1000-2000 j/kg range on Thursday which could be the most active weather day of the upcoming work week. Bottom line the 7 day forecast remains active and wet with WPC QPF values through next Sunday morning on the order of 1.00 to 2.00 inches.
- Near to above normal temperatures continue this week
Normal highs are in the lower 60s this time of year and we are forecast to be above that through the the 7 day forecast. The warmest day of the period will be Thursday where we could hit 80 along I-94.
AVIATION /06Z TAFS THROUGH 06Z MONDAY/
Issued at 220 AM EDT Sun Apr 28 2024
Low clouds will settle into the TAF sites overnight as low level moisture combines with areas of rain. Ceilings will dip to MVFR and possibly IFR late tonight and Sunday morning. After 15Z the ceilings will begin to lift due to the heating of the day and the fact the warm front may push a bit north into Central Lower Michigan. Areas of showers and a few isolated thunderstorms are possible overnight. Winds will be from the southwest both the remainder of tonight and for Sunday.
MARINE
Issued at 356 AM EDT Sun Apr 28 2024
A moist airmass remains in place today and Monday with dewpoint values into the mid to upper 50s. This moist air over cold water will produce dense fog along the lakeshore, therefore a Marine Dense Fog Advisory is in effect. Meanwhile, winds and waves should stay low through today and much of Monday. A cold front will approach the area late Sunday into Monday and may bring hazardous wind gusts as well as showers and storms.

MARINE...Small Craft Advisory until 8 AM EDT this morning for LMZ844>849.
