Area Forecast Discussion
National Weather Service Detroit/Pontiac MI
605 AM EDT Sun Mar 23 2025

.KEY MESSAGES...

* A mix of rain and snow will impact the area Sunday evening. Snow
  will be more likely north of the M 59 corridor and may be briefly
  heavy at times. Minor snow accumulations are possible.

* Windy conditions are expected Sunday night and Monday, with gusts
  over 35 MPH possible.

* Warmer weather is forecast to return late next week.

&&

.AVIATION...

High pressure in place at issuance will gradually be replaced by a
pair of low pressure systems currently over the Plains/upper
Midwest. Dry weather is expected for most of the day, with
increasing southeast flow as the pressure gradient inches closer.
Nose of the low level jet may arrive just before sunset to allow
gusts to reach 20-25 knots before nocturnal cooling and
precipitation stabilize profiles. Advertised band of rain and/or
snow pivots south to north through the airspace between roughly 21z-
03z. Models still generating all rain at DTW/DET/YIP, a rain-snow
mix at PTK/FNT, and either a rain-snow mix or all snow at MBS.
Cig/vsby restrictions will be greatest where snow is the dominant p-
type, potentially to IFR or below. A cold front sweeps across the
area between 01-07z or so and reduces precipitation intensity while
also shifting winds from SE to SW. Wind direction settles between
220-240 degrees with ensuing cold advection ramping up wind gusts
towards 25-30 knots even before daytime mixing. The tail end of the
TAF period may feature lingering rain and or snow showers owing to
lake enhancement, but confidence in coverage is low attm so did not
include in the TAF at this time.

For DTW... a cold front sweeps through the airspace between 01-05z
tonight, with SE winds (140 degrees) steadily veering to SW (230
degrees). Cold advection then ramps up post-front with wind gusts
increasing toward 30 knots after 05z. Latest guidance keeps wind
direction between 220 and 250 degrees through at least 18z Monday to
limit cross wind concerns.

.DTW THRESHOLD PROBABILITIES...

* High for ceilings below 5 kft by late this afternoon.

* Low for snow ptype tomorrow afternoon.

* Low for crosswinds through 18z Monday.

&&

.PREV DISCUSSION...
Issued at 335 AM EDT Sun Mar 23 2025

DISCUSSION...

High cloud will build aggressively around the noon hour, by 18Z as
the initial warm advection stage and lead axis of absolute vorticity
lifts into the region. Could see some virga on radar but a very dry
air mass will be in place below 10.0 kft agl. A freshening southeast
wind today with opaque will result in somewhat chilly conditions as
apparent temperatures are some 5 to 10 degrees below afternoon
highs.

A period of very strong synoptic scale ascent is forecasted to
impact Southeast Michigan later today (22z-05z) due to the alignment
of left exit region upper level jet dynamics, absolute vorticity
advection, and meridional warm air advection. Overall organization
of today's system is an open, baroclinic wave that remains
progressive with a very impressive nose structure to +60 knot low
level jet. The net result of the low level jet is an outstanding
presentation of progged, backed, very deep system relative upglide
on the 296-308 Kt surfaces. The environmental profile during the
precipitation is one of relatively higher static stability through
9.0 kft agl with steep lapse rates and even some conditional
instability above the midlevel warm front. From 00z-03z, saturation
with respect to ice is both very good through the dendritic growth
zone and throughout a good portion of the troposphere particularly
across the Tri Cities. With the strength of the UVVs, potentially
convective, and favored microphysics expecting a period of heavy
snowfall for portions of the Tri Cities and the Thumb. Limitations
on the event, are a very short duration of heavy precipitation rates
and warm pavement temperatures. A relatively warm environment will
develop particularly south of the I 69 and M 59 corridors as model
soundings show a warming environmental profile below 4.0 kft agl and
max temperatures rising to +4C during peak precipitation. Considering
the forcing with forecasted QPF, expectations are for a quick 1 to 2
inches of snow for grassy/elevates surfaces for the Tri Cities and
the Thumb. This is in line with the interquartile range of the EPS
solutions.

The other aspect of this system will be the wind. Forecast soundings
support steepening near surface lapse rates in the 06z-09z time
window tonight. Downward momentum transport in a deeply subsident
environment will support breezy southwest winds of 30 mph. Increased
mixing depths due to daytime heating will then result in windy
weather Monday. Will need to monitor forecasted moisture, cloud and
resultant mixed layer depths but the potential exists for wind gusts
of 40 to 45 mph on Monday.

Low confidence exists in how Pacific energy will slide into the
Upper Midwest and Great Lakes region during the Tuesday and
Wednesday timeframe. The energy will be ejecting out of an
anticyclonic wave break/supergeostrophic region in NW US. There has
been some model consistency in a fgen response occuring to the south
and west of the area over IL and IN.

Indications suggest a big warm up at the end of the week and next
weekend as a high amplitude ridge advances thorough the central
United States. There is some model signal that initial warm
advection precipitation chances will begin early Friday. Low
confidence exists in timing out precipitation chances for Saturday
with a heavy dependence on exactly where a surface warm front will
sharpen.

MARINE...

Southeasterly winds begin to strengthen late this morning as low
pressure reaches the Great Lakes from the upper Midwest. Winds
eventually peak around 25-30kts by this evening with sporadic gusts
near gale force possible particularly towards the Straits. Model
guidance still advertises enough warm advection to support enough
overlake stability to hamper wider spread/longer duration gales over
northern/central Lake Huron. Occluded front then sweeps through the
region late tonight-early Monday morning setting up WSW, gradually
turning W, flow for Monday. The low center will be around its lowest
pressure while sliding along the northern Lake Huron shore resulting
in potential (~60-70%) gales over the central and southern portions
of the lake as colder air filters in post-front first half of the
day Monday. A Gale Watch remains in effect for these waters as well
as Lake St Clair. MI waters of Lake Erie could see periodic gales
Monday morning but its detachment from the low lends to a more
marginal setup for both strength/duration. Low peels away from the
region Monday evening allowing winds to gradually weaken through
Monday night for the bulk of the region. Exception is northern Lake
Huron where the gradient briefly tightens in response to the
backedge working overhead with the departure of the low center.
Northwest winds reach the lower 30kt range Monday evening for these
waters before its local gradient likewise eventually slackens late
Monday night.
