.KEY MESSAGES...

- Chilly late May temperatures with gusty winds at times will
persist today into Friday.

- Rain is likely tonight and Wednesday.

&&

.AVIATION...

Low pressure tracks across the Ohio Valley tonight and Wednesday,
leading to periods of rain and steadily lowering ceilings toward IFR
by early Wednesday morning. Band of light rain has just reached KTOL
and KADG as of 1630z, but will become more scattered and showery in
nature as it encounters low level dry air in the metro Detroit
vicinity. Showers eventually reach the terminals this evening, which
will result in variable ceiling heights before a more cohesive surge
of low level moisture arrives early Wednesday morning. Showers
continue off and on through the end of the TAF period with winds
(10-13 knots) backing from E to ENE as the low migrates east.

For DTW/D21 Convection...best thunderstorm chances remain south of
the Michigan state line.

THRESHOLD PROBABILITIES...

* High for ceiling 5000 feet or less after 00z through Wednesday.

.PREV DISCUSSION...
Issued at 324 AM EDT Tue May 20 2025

DISCUSSION...

The upper low churning over the northern plains will undergo
considerable shearing over the next 24 to 36 hours. Additional mid
level troughing and convectively induced vorticity maxima will in
turn advance across the Ohio Valley late today through tonight.
There will be a strengthening axis of mid level deformation between
these waves and the high amplitude ridging across the eastern and
northern Great Lakes. The majority of model solutions drive this mid
level frontal forcing into SW Lower Mi this afternoon, then across
Se Mi late this afternoon and this evening, eventually into the
Saginaw Valley/thumb region toward Wed morning. The mid level
forcing will warrant high pops tonight. Considering the proximity to
the mid level ridging and greater depth of low level dry air, the
rain chances will remain lower in the thumb region tonight. The
easterly gradient will increase during the course of the day,
maintaining some degree of influence off the lakes. This and a
thickening high cloud canopy will limit diurnal heating, supporting
highs from the mid 50s to low 60s.

An elongated mid level low is forecast to evolve across the nrn Ohio
Valley and eastern Great Lakes region Wednesday. There are
variations among the model ensemble members as to the extent of
interaction between this developing low and another upper low
rotating into the northern Great Lakes from the James Bay region.
The main point of interest will be to what degree if any mid level
deformation is enhanced across central and southern Lower Mi. There
is at least enough support among the ensemble members to carry high
probabilities for rain. Model soundings also indicate ample low level
moistening. So even if the mid level forcing is a little on the lean
side, low level moist cyclonic flow should support areas of drizzle.
Sfc cyclogenesis across the eastern lakes will result in a
strengthening northeasterly wind off Lake Huron. This and the ample
low clouds will result in a very chilly late May day Wednesday with
forecast afternoon highs only in the low to mid 50s.

The aforementioned upper low over the northern Great Lakes is
forecast to expand southward Thursday before advancing to New England
by Saturday. This will maintain seasonally cool conditions across the
region into the start of the weekend before rebounding heights offer
a potential warming trend toward the end of the forecast period.

MARINE...

A low pressure system will cross the Midwest today before getting
deflected into the northern Ohio Valley and eastern Great Lakes by
Wednesday. This brings periods of rain and stronger winds for the
central Great Lakes. New Small Craft Advisories have been issued for
all the nearshore zones Tuesday morning through Wednesday morning.
Gusts should easily climb into the upper 20 knot range along the
coastal areas by Tuesday afternoon with occasional wave heights in
excess of 5 feet for most areas. Modest pressure gradient maintains
15-20 knot prevailing winds through Wednesday as the center of the
system moves into the eastern Great Lakes by Wednesday night. The
system will be slow to fully exit which keeps additional
opportunities for Small Craft Advisory extensions into the late week
time-frame.

HYDROLOGY...

An elevated front will bring the widely scattered to numerous rain
showers from south to north late today and tonight. Shower coverage
will expand north through Wednesday morning and afternoon. There is
reasonably high confidence that total rainfall from this afternoon
through Wednesday evening will be between a quarter and a half inch.
Chances for rain totals exceeding a half an inch are generally below
30 percent. The rain will occur over roughly a 24 to 36 hour period,
so flooding is not expected.
