LATEST UPDATE...
Synopsis/Discussion/Marine

.SYNOPSIS...
Issued at 330 PM EDT Thu Nov 4 2021

-Pleasant stretch of mild and dry weather

-Chance of rain Tuesday; better chance late next week

&&

.DISCUSSION...(This evening through next Thursday)
Issued at 330 PM EDT Thu Nov 4 2021

-Pleasant stretch of mild and dry weather

Moderating temperatures are the main story heading into the
weekend as we say goodbye to the upper trough and cold air that's
been around all week. Strong upper jet of around 130 kts coming
into the Pacific Northwest spreads eastward toward Lake Superior
by Sunday, pushing much milder air toward MI.

On Friday there is a thermal trough at H8 still hanging back over
MI, which may result in a good deal of stratocumulus clouds
sticking around for one more day - at least through midday. High
temps should be about 5 degrees warmer than today, up around 50
degrees.

The stronger push of warmer air from the west begins on Saturday,
although some cloudiness expected as a shortwave passes through
the nrn GrtLks Rgn. It will be rather breezy, with a southwest
wind gusting to 25-30 mph on the wrn/nrn periphery of the
elongated surface ridge stretching from ern TX across the Ohio
Valley to New England.

The warmest days in this pattern look to be Sunday and Monday when
upper ridge builds in and H8 thermal ridge of 10-12C pokes in.
High temps on these days could exceed 60, with partly to mostly
sunny skies.

-Chance of rain Tuesday; better chance late next week

A frontal boundary is shown to lean in from the northwest later
Monday or Tuesday, then eventually stall from lwr MI to TX for
the mid week period. A few showers many accompany the front as it
comes into the area, but the rain chances don't really ramp up
until about Thursday when a deep sfc low takes shape over the
Central Plains rgn. If this system evolves into a 988mb low over
Iowa as indicated by the ECMWF, could see a thunder threat toward
the end of the week, followed by a significant cool down for the
weekend of 11/13.

&&

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 124 PM EDT Thu Nov 4 2021

Confidence is high for VFR at all terminals for this TAF package.
Earlier today, high-based (VFR) stratocumulus was prevalent over
the area, but these clouds have eroded considerably, likely in
response to weak subsidence behind departing midlevel shortwave
trof. More recently, sunshine/heating has contributed to growth
of cumulus-topped boundary layer, with convective temps in the
low 40s F. JXN briefly reported MVFR cigs, but expect cloud bases
to continue to lift this afternoon, and all TAFs maintain VFR
cigs.

Overall trend will be for backing surface flow over time as
elongated anticyclone slowly propagates E/S of region. In
response, southwesterly winds will become established by Fri
afternoon.

&&

.MARINE...
Issued at 330 PM EDT Thu Nov 4 2021

A period of stronger southwest flow continues to look likely for
Friday into Saturday night so will issue a Small Craft advisory
starting Friday morning. Winds may even approach gale force for a
time north of Pentwater on Friday night. Will exclude the
southernmost marine zone from the advisory for now but that too
may begin to experience advisory conditions by later Friday night.

&&

.GRR WATCHES/WARNINGS/ADVISORIES...
MI...None.
