KEY MESSAGES
- There is a chance of showers and thunderstorms this afternoon.
Potential exists for a line of strong to severe storms to arrive late tonight. Damaging wind is the greatest threat tonight.
- Warm and muggy conditions with high temperatures in the mid to upper 80s continue through mid week until a cold front moves through the region Wednesday.
- There is one more chance for showers/storms Wednesday before a cooler and less humid air mass follows the front for the late week period.
AVIATION
Nighttime satellite displays extensive coverage of low-level stratus that has developed in the wake of low pressure, now in place across KMBS down to KFNT. The stratus deck is expected to hold just north of KPTK, but it may clip the terminal for a couple of hours. This stratus deck will further be reinforced from a strengthening low- level inversion, which would maintain coverage into the morning hours, producing mainly MVFR cigs, with some IFR possible. Sunshine will lift and scour out any stratus development by the late morning hours.
For this afternoon and evening, diurnal heating will provide the chance for isolated shower and thunderstorms development, but confidence remains very low regarding timing and coverage potential.
KPTK to KFNT have some signal for development in hi-res model output, where a PROB30 continues. There is a secondary chance for showers and storms as a line progresses across west Michigan overnight, between the hours of 1AM-6AM EDT. Coverage and intensity of this line is expected to wane as it approaches SE MI.
For DTW/D21 Convection...
There is a low chance for a shower or storm this afternoon and evening, but confidence is very low regarding coverage and timing.
The best window for any thunderstorm development would be between 18Z - 22Z.
DTW THRESHOLD PROBABILITIES...
* Low for thunderstorms this afternoon and evening.

DISCUSSION...
Window of deeper layer stability set to emerge through at least the first half of the daylight period, as shortwave ridging briefly governs conditions within the immediate wake of an exiting MCV.
Diabatic heating of resident warmth and humidity more typical of mid summer will gradually erode this stability through the day, augmented by renewed moisture advection fixated along a northward drifting frontal boundary. Ill-defined signal within the model spectrum regarding late day convective potential in an environment characterized as modestly unstable but generally lacking in larger scale forced ascent. Forecast will continue to highlight at least a lower probability of convective development, targeting a corridor within the M-59/I-69 region as localized areas of convergence or differential heating near the frontal zone and subsequent outflow/ lake breeze interaction offer the greatest potential. Plausible for a few stronger wind gusts to materialize as the degree of instability offers some water loaded updrafts, but lack of shear minimizes the opportunity for greater organization and a larger severe risk through the daylight hours. Highs today again landing solidly in the 80s.
Attention tonight focused on behavior of convection expected to organize across the midwest later today. High magnitude forced ascent featured within the elongated height falls and cold front attendant to the parent upper Miss valley trough will effectively drive upscale growth of this activity with a progressive transition toward a linear mode. The local convective potential and prospective vigor with this inbound convective line remains highly conditional on retaining sufficient destabilization, acknowledging the arrival window within a less favorable period /05z-09z/. A familiar position locally, which often lends to the greater potential holding just to the west. General consensus of the hi res model solution space suggests a gradual weakening trend as the convective line transits lower Michigan. Strong winds become the main threat should a greater response arrive locally for the early morning hours.
Trailing cold front arrives Wednesday. Frontal convergence remains weak as the boundary becomes parallel to the mean flow, but interaction with a moist boundary layer condition provides a limited window for convective development. Higher precip chance with eastward extent, with overall pace of the front relative to daytime destabilization dictating whether a more organized convective episode can manifest locally or remain to the east/southeast. Drying conditions with time through the latter half of the day.
Less active pattern to finish the work week. High pressure arrives Thursday, beneath lower amplitude mid level west-southwest flow.
Temperatures remain edged on the warmer side of average, but with notably lower humidity. Similar conditions hold into Friday as upper ridging migrates the region.
MARINE...
A front has stalled out across southern Michigan and will get pulled back north as a warm front today. The front will be associated with a strong low pressure system developing over the Plains that will lift up to western Lake Superior by this evening. The low will then send a cold front through the Great Lakes on Wednesday with showers and thunderstorms possible Tuesday night and Wednesday ahead of it.
Conditions are expected to remain below Small Craft Advisory criteria tonight through Tuesday, though locally higher winds and waves will be possible within any thunderstorms. Winds increase out of the south to 20 to 30 knots ahead of the associated cold front Wednesday, then veer to the west Wednesday night into Thursday while remaining gusty to around 25 knots. Less humid air settles in for the late week as high pressure builds in.
