Area Forecast Discussion
National Weather Service Detroit/Pontiac MI
146 PM EST Wed Nov 10 2021

.AVIATION...

A period of strong absolute anticyclonic vorticity advection has led
to a very dry atmospheric column below 20 kft agl this afternoon.
Satellite shows nothing but a cirrus veil clear back into central
Illinois and southern Indiana. NIL VFR conditions anticipated
through this evening. Models are very bearish on any precipitation
chances as lead wing of isentropic ascent saturates just a shallow
layer at/around 4.0 kft agl. Best potential for a brief sprinkle
would be at MBS but not enough there to carry a prevailing mention.
Well mixed conditions are then forecasted to develop after daybreak
with south winds of around 20 to 30 knots. Moisture advection will
then occur ahead of an approaching cold front. VFR to possible MVFR
cigs are expected after 18Z Thursday.

.DTW THRESHOLD PROBABILITIES...

* Moderate for ceiling 5000 ft or less tonight.

&&

.PREV DISCUSSION...
Issued at 323 AM EST Wed Nov 10 2021

DISCUSSION...

Dense Fog Advisories are in effect until 10am this morning as the
bulk of the CWA south of the Bay are reporting visibilities a half
mile or less. Fog should start to slowly burn off after sunrise.

Brief return to quiet weather today as surface high pressure and
subtle height rises build into SE MI. Despite the passage of a cold
front yesterday, temperatures remain slightly above average in the
mid 50s. Focus remains on Thursday with the next low. Parent upper
wave crosses the Rockies Wednesday spurning the developing of
surface low pressure roughly over the MO/IA/NE border region late
Wednesday. 00Z runs tonight of the Euro, GFS, NAM, and Canadian are
showing good consensus in the track of the low northeast into
western Lake Superior and the arrowhead of MN by Thursday evening.
Upper trough quickly becomes negatively tilted during this time
causing rapid deepening/maturation of the surface low. The
associated warm front lifts north across SE MI Thursday morning
allowing the richer theta-e plume to advance into the area by
Thursday afternoon. PW values climb to around or slightly over 1"
with this plume however the progressive nature of this system
assists in limiting the max QPF to below 0.5". System begins to
occlude as the cold front reaches lower MI with the cold/occluded
front driving across SE MI Thursday evening. An impressive dry slot
follows in the immediate wake of the front leading to an abrupt end
to rain activity by roughly 06Z (perhaps a bit earlier for the
western CWA). Troughing lingers across the central Great Lakes
Friday into Saturday dropping 850mb temps to -4 to -6C and
generating scattered lake effect rain/snow showers.

The other main impact from this system will be winds. The rapid
deepening tightens the pressure gradient locally daytime Thursday
strengthening southeasterly flow. LLJ develops Thursday morning
quickly increasing to around 50kts in the 850-900mb layer by early
afternoon. Forecast soundings are depicting a fairly shallow mixing
depth staying sub 900mb, however even this will be enough to mix
down 25-35kt winds to the surface. As such, have upped wind gusts
across the CWA Thursday afternoon/early evening to around 30kts.
Winds look to weaken slightly post fropa with system occlusion
weakening the low and gradually relaxing the local gradient.

Scattered lake effect rain/snow showers persist into Sunday as a
weak fast-moving shortwave drops out of the Canadian Prairie into
the central Great Lakes or Ohio Valley. There continues to be spread
in the exact track among tonight's runs with the GFS and Canadian
taking a southerly route into the Ohio Valley and the Euro taking a
northerly track more or less directly over SE MI. A more southerly
track will limit potential snowfall for the area (aside from
enhancing the lake effect response) whereas the Euro track would
lead to our first widespread accumulating snowfall. Still much too
early to say how it will play out. An interesting note is the 00Z
GFS shows another clipper-esk system ejecting from the northern
Rockies and swinging across the upper Midwest into the central Great
Lakes Tuesday. However no other longer range run depicts this and
instead take the wave much farther north to the Hudson Bay later in
the week.

MARINE...

High pressure to center across the Great Lakes through the morning,
bringing a period of light winds that will last through the early
evening hours. A major pattern shift will then commence late
tonight, lasting through the end of the week, which will result in a
rapid increase in wind speeds & gusts, along with rain and even snow
potential towards the end of the week.

A low pressure system will develop across the Midwest on Thursday
morning and will rapidly deepen as it then extends north into
western Lake Superior/Ontario by Thursday evening. This will allow a
strong warm front to push northern across the Great Lakes late
tonight into Thursday morning, with an energetic upper-level wind
field then overspreading across the Great Lakes, in advance of the
low pressure system. Surface winds will quickly back from west to
southeast after the passage of the warm front. A developing strong
pressure gradient combined with shallow mixing depths will be enough
to produce likely gales across northern Lake Huron starting early
Thursday morning. A Gale Watch remains as a result. Latest model
trends show gust to gales remain likely Thursday morning into the
early afternoon. The gale watch goes through the evening however, as
the strengthening pressure gradient has the potential to produce
sustained wind gusts to near gales through the day, owing to the
strength of the pressure gradient.

Gale Watch has been expanded to the next open water zone south in
central Lake Huron given trends showing gales persisting for long
enough to meet warning threshold. Remaining nearshore locations will
likely need Small Craft Advisories. Rain showers will be likely
across northern Lake Huron Thursday morning, with the passage of the
warm front. As low pressure occludes over the northern Great Lakes
late Thursday into early Friday, a cold front will draw over
Michigan. Mixing depths will increase behind the front but the
strong elevated winds are projected to move east out of the area.
This minimizes the chances to extended gales into the weekend.
Conditions will remain breezy while the low pressure/upper-level
disturbance brings on off rain showers, mixing in with snow showers
by the weekend.
