Area Forecast Discussion
National Weather Service Detroit/Pontiac MI
711 AM EDT Thu Aug 12 2021

.AVIATION...

Small convective complex will move across the Detroit terminal
corridor through 13z. Otherwise, tradually diminishing convective
potential this morning as background forcing wanes and brief
stability takes hold. No real evidence within model guidance to
suggest convective development will commence prior to this evening,
although given the underlying hot and humid conditions, a very low
end potential will exist. Otherwise, VFR conditions within modest
southwest flow. Secondary surge of moisture this evening and
overnight may afford the best potential for thunderstorms as a cold
front sinks southeast into the region. Confidence in occurrence at
this stage too low to highlight attm.

For DTW...Period of strong winds will accompany a small thunderstorm
complex through portions of the airspace through 13z. Some lingering
pockets of MVFR or low VFR then plausible late morning. Otherwise,
favor dry conditions throughout the daylight period. Potential for
thunderstorms again exist late this evening and overnight, but with
confidence still too low to highlight attm.

.DTW THRESHOLD PROBABILITIES...

* Low for ceilings at or below 5000 ft today.

* Low for thunderstorms this evening and tonight.

&&

.PREV DISCUSSION...
Issued at 419 AM EDT Thu Aug 12 2021

DISCUSSION...

Elevated thunderstorm activity continues on the edge of a strong LLJ
to 40 knots with elevated instability still in place on the order of
1000-2000 J/kg. Strong LLJ continues to surge in impressive moisture
into the region with latest SPC RAP values around 2.00 inches. Very
efficient rainfall rates expected with convection with main activity
leaving SE MI between 10-12Z. Prior to exiting, localized flooding
in urban and flood prone locations will be a primary hazard with
continued activity. MRMS radar estimates have shown accumulation
totals between 2-4 inches have fallen across portions of western
Wayne county, Washtenaw County, and Livingston. This has prompted the
issuance of several flood advisories. Additional trends will be
monitored for potential backbuilding/training.

Increasing stability in the wake of this convection and dry air
advection behind a passing weak elevated cold front will greatly
limit precipitation chances through the better part of the afternoon
hours. Flux of dry low-level air will drastically reduce available
instability for the northern half of the cwa. Rich theta-e air will
sink south and will maximize and stall around the northern Ohio
Valley. This will produce an instability gradient that extends north
to around m59, with CAPE values ranging between 1000-2000 J/kg --
highest values at the MI/OH border. Although this may be on the
higher end given the long lasting morning precipitation. In either
case, given limited mechanisms of forcing not expected too much in
terms of widely scattered development in the afternoon and early
evening, but will continue to hold a chance for PoPs given the closer
proximity to the ribbon of enhanced theta-e south of the border.
Otherwise, general thermal trends of the airmass remained unchanged,
with only a slight decrease in dew point temperatures noted across
the Tri- Cities and Thumb. This will produce another day of hot and
muggy conditions. Temperatures return into the upper 80s for most
locations, hitting 90 in a couple of spots across the Metro region.
Heat indices reside in the low to mid 90s.

Another round for late evening/nocturnal convection remains possible
pending convection trends across the Midwest. A likely source for
initiation will be along the advancing cold frontal boundary over
southern Wisconsin into northern Indiana. Downstream of expected
convective initiation, h850 flow will back from west to
southwesterly through the late afternoon with a general uptick in
strength, improving moisture transport across all of SE MI and
building and pushing the instability gradient north, across the Tri-
Cities and Thumb. Despite hi-res models failing to bring really any
convection in from the Midwest, building CAPE and a slight uptick in
bulk shear (~25-30 knots) could aid in maintaining any late evening
to overnight convective systems from the Midwest. While all of SE MI
will have a chance for late evening and overnight convection,
greatest probability to see any activity will reside across I-69
south. All hazard modes (damaging gusts, hail to an inch, isolated
tornado) are again in play given sufficient shear for organized
convection. High theta-e index values and steep low-level lapse rates
(prior to loss of daytime heating) will promote wet microbursts. An
isolated spin up also cannot be ruled out around m59 south given the
strong 0-1 km shear and building 0-1 km helicity values late tonight.
swody1 holds most of SE MI with a marginal risk for severe weather,
with best timing in the late evening into early Friday morning.

Surface cold front will also be in the process of dropping south
across Michigan through Friday morning. Some showers and
thunderstorms will be possible along and ahead of the boundary
through the mid to late morning hours on Friday, with the cold front
clearing the state after 12Z. Passage of this front will mark a
major pattern shift relative to the past week. Temperatures in the
upper 70s to lower 80s, decreased humidity, and dry weather are
expected through the weekend into early next week.

MARINE...

Lingering shower and thunderstorm activity early this morning will
gradually exit the marine waters over the next few hours. Sporadic
20+ kt gusts diminish throughout the morning as well. Main focus for
today then turns to yet another round of shower and thunderstorm
activity over the central Great Lakes, although coverage will be
more isolated in nature. Nonetheless, expect lightning, gusty winds,
and locally enhanced waves with any storms. Southwest flow flips to
northwest in the wake of a cold frontal passage on Friday followed
by expansion of high pressure into the Great Lakes region for the
weekend, producing light winds and dry weather through early next
week.

HYDROLOGY...

Ongoing convection will continue across SE MI, exiting the region
somewhere between 6-8 AM. Prior, very efficient precipitation rates
are noted with ongoing storm system, with 2-4 inches of precipitation
already fallen across western Wayne County, Washtenaw County, and
Livingston County. Over the next several hours (4-7 AM), an
additional half-inch to an inch of accumulation is likely mainly
along and south of I-69. Stronger thunderstorms or areas that receive
repeated activity will likely see localized higher amounts on the
order of 1-2 inches. Isolated areas of flooding in urban and flood-
prone regions will be likely with repeated thunderstorm activity.

Otherwise, expecting a relatively dry afternoon, with additional
chances for showers and storms late this evening into early Friday
morning. Uncertainty is too high with thunderstorm development at
this time to pinpoint any timing and resulting accumulation amounts.
