.DISCUSSION...(Today through next Wednesday)
Issued at 330 AM EDT Thu Sep 23 2021

--Rainy, breezy, chilly today-

Expect widespread rain today into the evening as closed upper low
near Toledo slowly lifts north toward Lake Huron. Additional
amounts expected to be mainly in the 0.50 to 1.00 inch range, but
some locally higher amounts possible especially this morning.

Will be cancelling the Flood Watch. Two day rainfall totals in
the JXN/LAN areas are generally only 1.5 to 2.5 inches and the
axis of heavier rain is now shifting west of the watch area.

Tight pressure gradient on the back side of the associated sfc
low over ern Lwr MI will lead to wind gusts around 30 mph from the
north-northwest. The wind and clouds/rain will hold temperatures
close to current temps around 50 much of the day, so a downright
nasty day for the first full day of fall.

-Sun/milder but still breezy Friday; Showers/storms Friday night

Today's upper low is booted out quickly on Friday as another one
drops southeast from Canada toward MN. We end up seeing quite a
bit of sun being inbetween the two systems, with winds increasing
from the south in the afternoon ahead of an approaching cold
front. Quite a swing in temperatures expected as highs surge into
the lower 70s in WAA pattern; about 20 degrees higher than today.

High likelihood of showers and a few thunderstorms on Friday night
as potent H5 shortwave and strong sfc cold front sweep through the
area. Another 0.50 of rainfall is likely for most areas with this
dynamic, quick-hitting system.

-Breezy/seasonal weekend; dry/pleasant next week

Showers with the next cold front clear the area quickly early
Saturday, but breezy westerly winds follow behind the front.
Cooler highs in the mid 60s expected in roller-coaster
temperature pattern, and probably a good deal of diurnal cu
forming. Then for Sunday the warm air surges back in again as
winds turn southwesterly and remain breezy.

Prolonged period of ridging and dry air expected next week,
leading to mainly dry conditions with temps near to above normal.

&&

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 1200 PM EDT Thu Sep 23 2021

A mix of mainly MVFR/IFR conditions will continue this afternoon
due to lingering low clouds and showers. In addition windy
conditions will continue this afternoon with north winds gusting
to 30 kts at times.

Conditions will gradually improve to predominantly MVFR and then
VFR tonight as the rain departs. In addition winds will diminish
to around 10 kts this evening and become westerly. VFR conditions
will then continue through 18Z Friday.

&&

.MARINE...
Issued at 330 AM EDT Thu Sep 23 2021

No change to the current marine headlines at this time, but the
Gale warning is on the marginal side. After the Gale Warning
expires, Small craft advisories will likely be needed through
much of the weekend.

Persistent stronger northerly flow has resulted in significant
upwelling along the coast, with buoy temps now in the 40s after
being around 70 for the last week.
