Area Forecast Discussion
National Weather Service Detroit/Pontiac MI
841 PM EST Tue Feb 21 2023

.UPDATE...

Ongoing mid level frontogenesis across central Wisconsin has been
producing a region of light snow. This fgen forcing will track across
the northern portions of the forecast area overnight, mainly north of
the I-69 corridor. Most recent hi res suite suggest the region of
strongest ascent will remain progressive as it tracks across the
Saginaw Valley and thumb region overnight. This and the expectation
for some weakening of this lead Fgen band will keep accums minimal
(under an inch). The current forecast has a reasonable handle on
this; high pops but with low QPF/snow amounts.

As this lead FGEN band lifts north of the area by 12Z Wed, the main
precip focus will be with the deep layer frontal forcing associated
with the wave lifting into the area from the southwest. No
minor adjustments will be made to the current winter headlines for
this system at this time.

&&

.PREV DISCUSSION...
Issued at 557 PM EST Tue Feb 21 2023

AVIATION...

High pressure will influence Se Mi this evening before exiting to
the east overnight. A rapid weakening of the sfc gradient along with
the onset of nocturnal cooling will cause a steady decrease in wind
speeds over the next couple hours. The loss in the diurnal
instability component will also allow some addition decrease in the
coverage of low end VFR based strato cu this evening. A narrow
elevated frontal zone will provide a chance for some light snow at
MBS in the 06Z to 09Z time frame. Otherwise, widespread mixed
precipitation (snow, sleet and freezing rain) will overspread the
southeast Michigan terminals between 15Z and 18Z Wed, with peak
precipitation rates expected late Wed afternoon and evening.

For DTW... Conditions will be relatively quiet through daybreak Wed.
Snow/sleet chances will then increase after 15Z and persist into the
afternoon, transitioning to all freezing rain. Sfc temperatures are
forecast to hover around or just below the freezing mark Wed
afternoon before rising just above Wed evening, so there will likely
be a transition toward all rain.

DTW THRESHOLD PROBABILITIES...

* High for a period of freezing rain and sleet Wednesday, dropping
  to moderate Wednesday evening.

* High for ceilings below 5000 feet Wednesday.

PREV DISCUSSION...
Issued at 330 PM EST Tue Feb 21 2023

DISCUSSION...

An epic battle of air masses will occur over Lower Michigan over the
next 48-60 hours. The southern wave/subtropical moisture currently
over Baja California will be the dominate player, as it is booted
off the to the northeast by the aggressive height falls/upper level
wave/jet dropping south from the Pacific Northwest. Record breaking
or near record moisture content from a climo perspective looks to be
overspreading into southeast Michigan on Wednesday, as 850 MB dew
pts of 10 C reach the southern Michigan border toward evening, with
700 MB dew pts of 0 to 2 C overspreading southeast Michigan,
advected by 70 knot jet. With 850 MB Li's going negative and mid
level lapse rates steeping up (~6.5 C/KM), a few embedded
thunderstorms seem plausible during the evening.

Meanwhile, a glancing blow of arctic air is tracking through Lower
Michigan behind this mornings cold front passage, allowing surface
dew pts to settle into the teens.

For impactful ice storms, surface temperatures of 31-32 degrees vs
30 degrees or colder makes all the difference.

With lack of snow cover over land, there is some concern skin temps
advertised by the models are too cold. Now, there does look to be
some light snow across the north half of the CWA tonight into
tomorrow morning with narrow mid level/700 MB fgen/isentropic ascent
arm, but would expect accumulations to remain under 2 inches.

A bigger concern is the lack of ice cover over Lake Huron and minor
heat flux from the water temperatures in the mid to upper 30s as
easterly flow is locked in tomorrow. Sub 1000 MB surface low will be
tracking into the western Ohio Valley late in the day, and the well
defined warm front will remain south of the Michigan border through
00z. With strong surface high (1035+ MB) building over/near James
Bay through the day, banking on surface winds to actually become
northeast in the afternoon, which should allow for shallow cold
advection as colder air from southern Ontario bleeds in which will
attempt to offset the latent heat release of the freezing rain and
warming 850 MB temps rising into the mid to upper single numbers
Wednesday evening south M-59. Very tight north-south baroclinic zone
over the Central Great Lakes makes for difficult forecast
determining advisory/warning for the various tiers of counties. With
mid level dry slot overtaking all of southeast Michigan after
midnight, banking on a significant break in precipitation to end
this first phase/event before the second low arrives during the day
on Thursday. That low looks to be tracking significantly farther
north, thus any possible winter weather advisory decision should be
confined to the northern part of the CWA. However, the rise/fall
pressure couplet late in the day with the cold advection will have
to be considered for a wind advisory for much of southeast Michigan
with 40+ knots of flow at 925 MB and 50 knots at the 850 MB level.

As far as the decision points for tomorrow afternoon/evening, bulk
of the 12z hires solutions ARW/regional GEM/Euro are adamant in the
surface cold air holding, and locations along/M-46 should be deep
enough in the cold air to maintain snow with some sleet mixing in at
times with warm layer in and just below 10 kft coming advancing in.
Will go with winter storm warning for 4-8 inches of snow/sleet
(lower end if more sleet mixes in). The I-69 corridor looks to be in
for a wintry mix bag of precip. Although we may come up short with
the individual elements snow/sleet, enough of concern/expectation
for freezing rain/ice accumulations to near quarter of an inch and
will go with a winter storm warning. More solid ice storm warning
conditions anticipated along the M-59 corridor extending into
Washtenaw county. Based off the ice accumulation calculator and
using a temp of 30 degrees, qpf of 1 inch, and expected winds around
15 knots...ice accumulation of quarter of an inch to half an inch
(radial) looks reasonable. That amount of ice will be capable of
taking down tree branches and lead to possible scattered power
outages.

With marginal freezing surface temps over Wayne and Lenawee/Monroe,
as well as the warmer rain drops with the deeper warm layer, will
just be carrying an winter weather advisory for ice accumulations
around tenth, with northern Wayne around two tenths before complete
changeover to rain occurs early Wednesday evening.

Much colder air settles into the region Friday in the wake of the
departing system - the air mass characterized by 850mb temps in the
negative middle teens Celsius. Northwest winds will gradually taper
off as the pressure gradient relaxes during the day, but with highs
in the teens to 20s, we can expect wind chills to hold in the single
digits to teens through the afternoon. Cold advection over the still
open waters of Lake Michigan will bring a good coverage of lake
effect clouds with boundary layer thermodynamic profiles offering a
slight chance for some flurries if enough moisture can traverse
across the state.

The cold will be short lived as a warm front is on track to lift
across the area Saturday morning. This feature will bring a chance
for some light snow mainly the first half of the day, then temps
should return to near normal values in the lower to mid 30s by the
afternoon. A clipper drops into the Great Lakes by Saturday evening,
leading to a surface low developing near Lake Superior that drags a
cold front through. This shot of cooler air will only graze the area
on Sunday as medium range guidance advertises a deeper low
developing in the lee of the Rockies and bringing a stronger push of
warm air late Sunday into Monday. The next round of widespread
precipitation is likely on Monday as this system tracks across the
region.

MARINE...

Gale potential will quickly dwindle across most locations outside of
northern Lake Huron as the strong low-level jet associated with a
low pressure system shifts east out of the Great Lakes. Attention
then quickly turns to the next winter storm system which will bring
a multitude of weather types along with the return of gales for the
greater portion of the Great Lakes.

An elevated frontal boundary will initially bring light snow across
Lake Huron starting early tomorrow morning. Snow chances will
continue through the day with snow intensity expected to increase
through the late evening hours into early Thursday morning as low
pressure builds into the Ohio Valley. The Saginaw Bay and portions
of central and northern Lake Huron will be subject to the stronger
snow rates which will produce drastic drops to visibilities at
times. For southern Lake Huron and Lake St. Clair, freezing rain and
sleet are likely through the afternoon into early Thursday morning
leading to icing concerns on vessels, while rain is the most likely
precipitation type for western Lake Erie.

For winds, wind direction will flip from northwest to east-northeast
in advance of the approaching low pressure system. Sustained wind
speeds and gust will increase in intensity as a strong pressure
gradient develops over Michigan. Sustained winds to or just above 30
knots along with gusts to gales will be likely across the Saginaw
Bay into central and north-central Lake Huron. There is high
confidence for gust to gales lasting through Wednesday into Thursday
morning, where a Gale Watch is currently in effect. The Gale Watch
does extend into Thursday evening, however, confidence is lower
regarding these gales as it will be pending the path of a secondary
low pressure system, projected to fill in across southern Michigan
on Thursday. Gale potential is increasing for St. Clair and Erie on
Thursday with this low pressure, thus considerations for a gale
watch/warning will be made with future updates.

HYDROLOGY...

A widespread area of precipitation will expand across the region
Wednesday and Wednesday night. While the potential exists for some
of this precipitation to fall as a frozen wintry mix, areas
particularly from the I-69 corridor south are expected to witness a
period of freezing rain transitioning to rain. Higher intensity
rainfall rates are expected at times, with even the possibility of
rumbles of thunder. This will contribute to rainfall amounts
reaching or exceeding an inch in many locations. This will result in
very minor flooding within poor drainage areas and rivers rising to
bankfull.
