No hazardous weather is expected at this time.

Days two through seven: Thursday through Tuesday

An isolated thunderstorm will be possible Thursday afternoon across Southeast Michigan in advance of a cold front.

Spotter information statement

Spotter activation will not be needed today and tonight.

Key messages

- There is a chance of showers and an isolated thundestorms Thursday afternoon and Thursday night.

- Dry and continued mild this weekend.

Aviation

SE Michigan resides between high pressure off the mid-Atlantic Coast and low pressure over the Upper Midwest. This has resulted in a gradual veering and strengthening trend to surface winds, with direction expected to shift from south this evening to the southwest by Thursday morning. This occurs ahead of a cold front that will reach MBS mid-morning and slowly migrate across the airspace by Thursday evening. Moisture along the front will struggle to survive as the low level jet pushes moisture transport north and remaining moistures mixes with the dry airmass that is currently in place. While a narrow band of showers and/or MVFR cigs may develop along the front Thursday, the broader expectation is for cigs to be low VFR with light rain given the decreasing moisture quality. Less than 500 J/kg of MUCAPE exists, although with lapse rates of 6.0-6.5 C/km, cannot entirely rule out a thunderstorm or two again along the frontal passage. Winds post-front veer further to the west and eventually the northwest by Thursday evening.

D21/DTW Convection: Marginal instability will accompany a cold frontal passage Thursday afternoon-evening. There is a low chance a thunderstorm may develop along the front.

Dtw threshold probabilities

* Medium for ceiling at or below 5000 feet Thursday afternoon and evening.

* Low for thunderstorms Thursday afternoon and evening (mainly 20z to 00z).

DISCUSSION:

A jet exit region and upper level confluent flow will migrate towards the Canadian Maritimes during the next 36 hours. The 1000- 500mb ridge will amplify over Lower Michigan, dampening the effects of a deep shortwave trough lifting out of the Northern Plains to James Bay. Precipitation free conditions can be expected for the remainder of today ahead of the cold front along with temperatures some 15 degrees above normal. A relatively dry cold front draped from the shortwave will push across the forecast area between 18z Thu - 01z Fri.

Relative humidity progs in the plan view show an extremely narrow moisture starved boundary as it pushes across the area, limited to only a few tens of miles across. The current forecast has likely pops of 50-60% percent between 18-00z which is adequate. The overall ageostrophic circulation is expected to be very weak with lean 850- 700mb frontogenesis. Forecast soundings show static stability lingering between 4.0 -7.0 kft agl limiting coverage of activity with MUCAPES of a few hundred J/kg. Latest Swody2 has now introduced General Thunderstorm designation for Southeast Michigan. Warm temperatures are anticipated Thursday ahead of the front with readings pushing into the lower 70s.

Anticyclonic curvature to the zonal jet streak in portions of central Canada will lead to strongly anticyclonic flow curvature over the Great Lakes Friday and Saturday. High confidence exists in strong static stability between 3.0 and 17.0 kft agl. Southeast Michigan will reside in the gradient to the 1000-500mb thickness tempering high temperatures both Friday and Saturday in the lower 60s.

Longwave ridge is forecasted to build across the region this weekend and then continue into the beginning of next week. Current high temperature forecasts suggest temperatures reaching the middle 60s some 7 to 10 degrees above normal. Any pattern change with the arrival of Pacific energy appears to hold off until after Day 7, Tuesday.

MARINE:

Southwest winds will be on the increase tonight ahead of a cold front. However, the warm advection pattern will help limit mixing depths. Nonetheless, the strength of the low level jet and magnitude of the pressure gradient do look to support gusts at or above 25 knots, most prevalent over Central Lake Huron extending back into Saginaw Bay. A Small Craft Advisory has been issued from late tonight through Thursday morning for these wind gusts. Offshore flow, however, should keep waves mostly in the 2 to 4 foot range however.

Behind the cold front, wind speeds look to be maximized over northern Lake Huron where cold advection is most robust. 850 MB temps progged to fall below zero Thursday night, promoting deeper mixing and northwest gusts of 25 to 30 knots. Confidence is high in a period of 25 to 30 knot gusts over northern Lake Huron. High pressure quickly builds into the central Great Lakes Friday afternoon, setting up lighter winds and dry conditions over the weekend.

Watches, warnings and advisories

MI: None. Lake Huron: Small Craft Advisory from 4 AM to 3 PM EDT Thursday for LHZ421-422- 441.

Lake St Clair: None. Michigan waters of Lake Erie: None.
