104 PM EST Sat Nov 11 2023

LATEST UPDATE...
Aviation

.SHORT TERM...(Today through Sunday)
Issued at 312 AM EST Sat Nov 11 2023

-- Benign November Weather For Veterans Day --

Light lake-effect rain showers this morning will tend to diminish
as low-level ridging and surface high pressure move through the
region. It appears that at least part of this Veterans Day will
feature sunshine, especially away from Lake Michigan, though just
enough moisture remaining in the lower levels will keep our area
on the cusp of developing patches of stratocumulus by afternoon.
Temperatures will be a touch cooler than normal.

-- Slight Chance Precip Northwest Tonight Then Breezy Sunday --

Southwesterly low-level flow strengthens tonight in the gradient
between the eastern Great Lakes high and troughing under an upper-
level PV anomaly over the northern Minnesota border. Mid- level
clouds will increase and may precipitate lightly from isentropic
lift overnight north of Whitehall and Big Rapids. Have slight
chance PoPs there, and it may be cold enough in the higher
elevations of Osceola county for snow flurries.

Sunday will be warmer but breezier than Saturday, and mostly
sunny skies are favored in southern Michigan. Winds from the south
will gust to about 15 mph around Jackson and 30 mph around
Ludington.

.LONG TERM...(Sunday night through Friday)
Issued at 312 AM EST Sat Nov 11 2023

-- Above Normal Temps and Dry Most of Next Week --

Positive height anomalies prevail next week, with uneventful
split flow pattern aloft and ridging generally dominating. This
supports a stretch of unseasonably warm temps with highs of 55-60
and dry weather. PWATs are shown to be quite low, often below
0.25", suppressing rain chances and offering several opportunities
for sunshine. The dry air mass will likely also promote chilly
overnight low temps with diurnal temp swings of 20-30 degrees
possible.

-- Rain Showers Possible to End the Week --

Rain chances return Thursday night into Friday as the nrn branch
of the upper jet buckles southward and sends a trough and sfc cold
front through the GrtLks region. Will keep pops in the chance
category for now given uncertainty in the magnitude of the upper
trough/sfc front as well as questionable moisture availability.

&&

.AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon)
Issued at 1258 PM EST Sat Nov 11 2023

High pressure over the TAF sites will act to keep the winds on the
relatively light side. Some clouds have developed early this
afternoon and they could feature a brief MVFR ceiling for a few
sites. Overall though, VFR conditions are expected to prevail most
of the time. Mid level VFR clouds will arrive this evening as a
warm front approaches. Light precipitation may fall out of these
clouds, but the dry conditions near the ground are expected to
evaporate the precipitation before it reaches the ground(virga).
The winds near the lakeshore will increase Sunday morning and
gusts may start to top 20 knots at KMKG.

&&

.MARINE...
Issued at 312 AM EST Sat Nov 11 2023

Light and variable winds over the water today will become more
established from the south-southwest Sat night through Sun.
Conditions will likely become hazardous for small craft north of
Holland Sun morning, then the hazards expand southward Sun night
into Mon. Gusts approaching gale force are possible Sun evening,
particularly north of Holland to Manistee.
