KEY MESSAGES

- A prolonged period of heat and humidity will continue through the week. Excessive heat warnings and heat advisories are in effect.

- There will be periodic chances for thunderstorms throughout the week. Locally heavy rainfall will be primary driver of impacts.

AVIATION

Thunderstorms finished their evening run leading up to midnight leaving just a stray shower or rumble of thunder possible during the late night. There is little else of concern outside of convective trends under VFR clear to scattered sky condition until a brief period of fog or haze becomes possible with wet ground now combined with the already humid air mass. A couple of hours of MVFR restriction is likely around sunrise even with a 5 to 10 kt wind.
The afternoon then brings more of the same hot, humid, and unstable conditions along with another pattern of showers and thunderstorms having even greater organization. Given larger scale mid level support moving in from the MS/TN valleys, mid afternoon storm initiation is likely with similar timing across the terminal corridor which then moves eastward toward Tuesday evening.

For DTW/D21 Convection... A stray shower or rumble of thunder remain possible late tonight as warm and humid air is now rooted across Lower MI. A morning pause in convection is expected followed by another round of storms in the afternoon, likely with greater coverage across the bulk of D21.

DTW THRESHOLD PROBABILITIES...

* Moderate for thunderstorms mid to late afternoon into Tuesday evening.

* Moderate for ceiling at or below 5000 ft, conditional with thunderstorms.

DISCUSSION...

Amplifying upper-level ridge episode over eastern North America and correlated building heat dome is well underway. Surface dewpoints are surging into the lower 70s with temperatures climbing to around 90 - pushing heat index values into the upper 90s. Furthermore, low temperatures will only settle back to around 70 with higher readings in the urban settings (mid-70s). These conditions will be the norm for the balance of the work week and will take its toll on exposed populations - hence the long duration heat advisory and excessive heat warning.

Subsidence in the wake of the morning mesoscale convective vortex and associated thunderstorms is starting to lose influence across southern Lower Michigan. There is still evidence of a ribbon of anti- cyclonic enhanced flow aloft over Southeast Michigan in the GOES-WV imagery. Consequently, expect the suppression of deeper cumulus development to continue over the next few hours. The scattered activity along the periphery over the Saginaw Valley will continue to bubble northeast across the thumb. While there is plenty of instability to tap (MLCAPE > 2.5-kJ/kg) with adequate depth (>2-km), there is very little flow and/or shear to support scaled growth.
Therefore, heavy rainfall is the primary outcome with some wet microburst potential with hydrometeor loading in deeper cells.

The quality of instability on Tuesday will not be as good, but a north-south oriented buoyancy gradient in the 1-2-km layer will linger over Southeast Michigan. This in combination with better jet level forcing rolling north into the region will help initiate scattered thunderstorms once again. Precipitable water values will increase to well over 1.75-inches - supporting intense downpours once again. If the buoyancy gradient maintains integrity along the mean flow vector, convective training and resultant flash flood potential will be more likely. Still some variance in guidance offerings, but a small cluster of heavy rainfall outcomes is very evident.

The mid-levels do not get dramatically warm with this heat dome; therefore, afternoon convection is possible each day through this heat spell. Medium range guidance is now suggesting that the current heat will grab another day on Saturday with the timing of the next shortwave and cold front remaining questionable.

MARINE...

Southwest winds will continue to advect hot and humid air into the Central Great Lakes through the mid week period. High degree of surface stability with the cooler waters should keep wind speeds under 25 knots through the rest of the work week. The exception will be in and near and strong thunderstorms which develop. Timing and location will be highly uncertain, but the typical peak heating of the day into early evening hours will be favored. Indications are the surface frontal boundary will be sinking south Thursday and Friday as seasonably strong high pressure tracks through Ontario.
This will allow for light northeast/northerly flow (~15 knots) over Lake Huron. Airmass will remain warm, thus any wave build up with the longer fetch remains below 4 feet.

HYDROLOGY...

A moist and unstable airmass will be in place across the region through Tuesday. Scattered thunderstorms are expected this afternoon and again Tuesday afternoon. The most intense thunderstorms have the potential to produce rainfall amounts in excess of 2 inches over a short period of time, resulting in urban and low lying area flooding. Uncertainty in specifics for both timing and potential for flooding precludes issuance of a flood watch, at this time.
