KEY MESSAGES
- Severe storms exit by 7 PM.
- Another round of showers move through Thursday night.
- Drier and cooler weather Friday and into the Weekend.
DISCUSSION
Severe thunderstorm watch remains in effect until 7 PM, but the line is moving through at a good clip, and watch will likely be canceled early.
Surface dew pts have mostly topped out around 60 degrees, and MLCapes have risen to 1000 J/kg but coming up short of 1500 J/kg (except right along the southern Michigan border). A few discrete cells in the line have been rotating with effective bulk shear in excess of 30 knots. Theses storms have produced large hail (Ingham county) and damaging winds (Williams county), but the bulk of line just has just produced non-severe wind gusts of 40-50 mph thus far.
Isolated tornadoes remain possible, especially over the southern counties.
Sharp convergence line, with southerly winds ahead of the front, followed by breezy westerly winds behind the front this evening as the surface low (998 mb) over northern Wisconsin slowly weakens and heads off to the northeast.
Westerly winds look to remain somewhat elevated tonight, around 10 knots, with cold advection through the night as 925 mb temps lower into the low single numbers by 12z Thursday. Even so, low clouds likely hold min temperatures in the 45 to 50 degree range.
Large and elongated (west-east) upper level trough/low over south Central Canada extending back into the northern Rockies will slowly wobble off to the east, with the trough axis passing through the Central Great Lakes on Saturday. Before this occurs, a surface low and deeper Gulf of Mexico and Pacific moisture will become absorbed in the deepening southwest flow and race off to the northeast tomorrow and tomorrow night. PW values reaching 1 inch late tomorrow over southeast Michigan, with the sharp moisture gradient setting up over Central/Eastern Great Lakes Thursday night. Good low level FGEN should support widespread rain moving through southeast Michigan.
But even this rain shield looks progressive, and total amounts under half an inch expected.
Much drier air to follow for Friday and into the Weekend, supporting dry and cooler weather (slightly below normal).
MARINE
Weakening low pressure continues to slide towards the Straits this evening as its attendant cold front sweeps through the central Great Lakes. A line of showers and thunderstorms will precede this front with some storms being strong to severe with both large hail and >34kt wind gusts possible- mainly from southern Lake Huron/Saginaw Bay south. Winds back to westerly behind the front tonight with the loosening gradient allowing flow to weaken to aob 25kts. Brief period of ridging sets up for Thursday supporting favorable marine conditions across the region. A second cold front then sags south into the area late Thursday night into the first half of Friday offering another shot at widespread showers and perhaps a few thunderstorms mainly focused over the southern Great Lakes. Cooler westerly flow follows the fropa supporting an uptick in wind strength latter half of Friday into this weekend- peak gusts generally topping out between 20-30kts.

AVIATION...
Broken line of convection evident on radar attendant to an advancing frontal boundary on pace to move across the southeast Michigan airspace late this afternoon. Downstream extrapolation of the movement brings this activity through between 19z and 21z, highlighted by potential for brief strong to severe thunderstorm intensity featuring strong winds and a rapid reduction of visibility in heavy rain. Existing south/SE wind shifts to southwest in the wake of the convection and trailing boundary heading into early evening. Infusion of colder air will promote some degree of lower stratus development lasting through tonight. Forecast will continue to outlook a transition from low VFR to MVFR restrictions associated with a steady increase in low level moisture.
For DTW/D21 Convection...Inbound broken convective line set to arrive within the 19z-21z window. Expect reduced visibility from heavy rainfall and strong winds from any stronger thunderstorm.
DTW THRESHOLD PROBABILITIES...
* High for ceiling aob 5000 ft through Thursday morning.
* High for thunderstorms impacting terminal between 19z and 21z.
DTX WATCHES/WARNINGS/ADVISORIES
MI...None.
Lake Huron...Gale Warning until midnight EDT tonight for LHZ361-362.
Small Craft Advisory until midnight EDT tonight for LHZ421-422- 441>443.
