Area Forecast Discussion National Weather Service Detroit/Pontiac MI 1111 PM EDT Tue May 31 2022 .AVIATION... A weakening cold front will sag southeast through the area late tonight into Wednesday morning. Scattered showers and possibly an embedded thunderstorm or two will funnel through the area in advance of this front with thunderstorm activity most likely KFNT and KMBS overnight and along I-94 on Wednesday morning as a wave of low pressure tracks along the front over/near the area. MVFR stratus looks to filter into the area in the wake of the front Wednesday morning. This stratus may hold on into the mid or late afternoon before lifting and scattering out. Southwest flow will veer to northwest with the fropa. For DTW...Will further delay the period of scattered shras to 12z- 13z and retain the PROB30 for tsra. Will also maintain the period of MVFR stratus but delay it until afternoon once the cold front clears the area. .DTW THRESHOLD PROBABILITIES... * Low for thunder late Wednesday morning. * Medium for ceiling at or below 5000 ft after 16z Wednesday. Low again after 00z. && .PREV DISCUSSION... Issued at 311 PM EDT Tue May 31 2022 DISCUSSION... Southeast Michigan firmly entrenched late this afternoon within the higher magnitude warmth offered within existing deeper layer southwest flow fixated along the northwest flank of prevalent southeast upper ridging. Late day readings peaking near 90 degrees in many locations. Standard diurnal boundary layer destabilization ongoing - recent mesoanalysis indicating an axis of higher instability elongated from central IL to west-central featuring in excess of 1500 j/kg. Lack of meaningful forced ascent within the background of a sufficiently capped mid level profile effectively mitigating a convective risk through the peak heat cycle. Attention directed upstream, as a lingering source of vorticity - likely remnants of convection last night - works in combination with a southeast sagging weak frontal boundary or pre-frontal trough to engage the existing max instability axis draped from northern Illinois northeast across southern/central lake Michigan and far west-central lower MI. Some degree of convective organization and east-northeast expansion expected yet this evening given adequate bulk shear within the immediate downstream instability reservoir residing into western lower MI. With this said, defining potential convective integrity as this activity evolves overnight and arrives locally remains somewhat uncertain yet owing to a general lack of large scale ascent to overcome lingering capping concerns and the standard expectation for a gradual decline in instability magnitude with time and east/southeastward extent post-sunset. The Tri- cities/Saginaw Bay region most favorably positioned to sustain ongoing convection or offer some renewed expansion/organization given proximity to the highest instability, slightly better wind field and earlier prospective timing for activity to arrive. Main threat window remains centered 02z to 09z - with a standard hail/wind risk. Noted increase in mid level theta-e attendant to the advancing frontal convergence zone maintains at least a chance of convection into the early-mid morning hours across central/southern sections. A gradually drying post-frontal environment will mark the Wednesday period. A secondary frontal boundary will emerge off lake Huron late in the day as low level flow veers with time over the waterways. There remains a weak signal yet for a localized area of convergence to develop along this feature during peak heating to capitalize on steeper lapse rates, supporting a very low chance for garden variety convection despite a much drier overall profile. Otherwise, noted decrease in overall temperature magnitude - highs generally mid 70s to lower 80s, but likely holding in the 60s over the northern thumb given the colder onshore flow. Deeper plume of moisture attendant to weak shortwave energy working through the mean flow will advect across the northern Ohio valley Wednesday night and Thursday. Northern expanse of this moist axis will glance across far southern lower MI, offering low end potential for light shower development near the Ohio border. Prospects for a higher coverage of cloud Thursday will supplement an already cooler resident thermal profile - ensuring temperatures arrive below average for the first time in over a week. Prevailing lower amplitude west-northwest flow absent of meaningful pv lends to a stretch of benign weather with lower humidity and gradually moderating temperatures Friday and Saturday. MARINE... Southwesterly winds continue through the remainder of the day before a cold front drops across the central Great Lakes tonight. Showers and thunderstorms are possible throughout much of the night ahead of this front. Front likely is still draped across far southern Lake Huron down to Lake Erie Wednesday morning keeping chances for storms over these areas through the first half of Wednesday before the front slides further south into Ohio. Unsettled weather possible through Thursday as another low looks to develop along this front Thursday and track through the Ohio Valley. High pressure then builds over the region for the weekend. && .DTX WATCHES/WARNINGS/ADVISORIES... MI...NONE. Lake Huron...NONE. Lake St Clair...NONE.
