...Storms About to Impact the Lakes...

.An intense low pressure system remains on track to cross through the 
Great Lakes today. Moderate southeast winds are underway in advance 
of this system as the center of the surface low begins to move into 
western portions of Lake Michigan. The current track will bring 
gusts near 30 knots across portions of northern lake Huron through 
the morning hours. A pronounced increase in winds from the west-
southwest are then expected by the afternoon as cold air advection 
begins in the wake of this strong low. A long duration high wind 
event will then ensue and last into tonight with sustained west-
southwest winds of 30 to 35 knots gusting 40 to 50 knots. Peak wind 
gusts will be exceeding 50 knots at times throughout the afternoon. 
A Storm Warning remains in effect for all of Lake Huron and Lake St. 
Clair with a Gale Warning for western Lake Erie. Gale force gusts 
will persist into Monday for portions of northern and central Lake 
Huron before winds begin to decrease late Monday with the weakening 
pressure gradient. High pressure building into the region will bring 
more modest northwesterly flow into the middle of the week.

URGENT - MARINE WEATHER MESSAGE
National Weather Service Detroit/Pontiac MI
335 PM EST Sun Feb 24 2019

...Storm force winds through tonight...

.An intense low pressure system will track from the northern great 
lakes today to western Quebec tonight. The combination of a strong 
pressure gradient associated with this system and the arrival of 
colder air will maintain a long duration high wind event lasting 
into early Monday. Sustained westerly winds of 30 to 35 knots with 
gusts 40 to 50 knots will be common, with peak gusts exceeding storm 
force during this time. A Storm Warning remains in effect for all of 
Lake Huron and Lake St. Clair with a Gale Warning for western Lake 
Erie. Gale force gusts will persist into Monday for portions of 
northern and central Lake Huron before winds begin to decrease late 
Monday with the weakening pressure gradient. High pressure building 
into the region will bring more modest northwesterly flow into the 
middle of the week.

Area Forecast Discussion
National Weather Service Detroit/Pontiac MI
1209 PM EST Sat Feb 23 2019

.AVIATION...

An intensifying low pressure system on pace to impact the southeast
Michigan airspace tonight into Sunday. Extensive mid cloud defining
conditions today, with cigs gradually lowering with time going
forward this afternoon and evening as moisture deepens in advance of
this system. Coverage of showers increases overnight in developing
IFR/LIFR conditions, with a window for embedded thunder centered
04z-09z. Strengthening wind field will first lead to a period of low
level wind shear above a 10-15kt southeast gradient tonight. The
ensuing post-frontal mixing favorably timed during the daylight
period will then translate into a long duration high wind event on
Sunday. West-southwest wind gusts reaching in excess of 45 knots at
times during the afternoon and evening periods.

For DTW...Cigs gradually lowering into the evening, with increasing
likelihood for sub-5000 ft ceiling heights to emerge by sunset.
Increasing shower coverage w/ possible embedded t-storms between 04z
and 09z. Potential for LIFR cigs during this time. Strong west-
southwest winds expected Sunday - gusting over 45 knots at times.
Winds from a 230-240 direction will keep cross wind considerations in
play during this time.

.DTW THRESHOLD PROBABILITIES...

*  Moderate for cigs below 5000 ft late this afternoon into the
   evening. High tonight.

*  Low for thunderstorm occurrence tonight.

*  High for precipitation type to remain rain through Sunday morning.

*  Medium for west-southwest winds reaching crosswind thresholds
   Sunday.

.PREV DISCUSSION...
Issued at 317 AM EST Sat Feb 23 2019

DISCUSSION...

A short wavelength, yet deep and compact, mid level wave will lift
from the Texas panhandle this morning into western Wisconsin late
tonight, then across Upper Michigan Sunday morning. Associated with
this wave will be a deepening sfc low, forecast to deepen from 999MB
over Kansas this afternoon to 979MB over Eastern Upper Mi Sun
morning. The low will then continue to deepen as it lifts northeast
of Lake Superior Sunday afternoon. This system will have a relatively
tight gradient and strong low level wind field associated with it.

The 2-5k ft level winds will strengthen to 50-60 knots overnight.
Strong boundary layer stability will inhibit these stronger winds
from reaching the surface overnight. Model solutions indicate a
stronger push of low level winds along the associated surface cold
front (forecast to traverse Se Mi between 12Z and 15Z Sunday). A
brief period of downward momentum transport, with model soundings
showing a rapid reduction in 0-1KM stability, will provide an
opportunity to mix some stronger winds to the surface (with a brief
interval of gusts in excess of 55 MPH possible). Strong low level
winds (2-4k ft winds of 50-60 knots) will then reside across srn Mi
through Sun evening. The potential for strong wind gusts through the
remainder of the day and evening will hinge on the degree of mixing.
The diurnal heating process and steady low level cold air advection
will result in deepening mixing depths. Low level moisture wrapping
around the departing upper low may however limit this to a degree.
Given the strong low level wind fields, wind gusts in the 45 to 55
MPH range seem very achievable. A few gusts up around 60 MPH
certainly remain in play. Therefore, the high wind watch for Sunday
will remain in effect.

A lead mid level short wave impulse lifting from Iowa into Wisconsin
today will enhance a region of moist isentropic ascent from the
western Great Lakes this morning into central and northern Michigan
this afternoon. This will actually give the better chance for light
rain across the Saginaw Valley later today. Low level moisture
advection will however support a chance for light rain and/or some
drizzle across the remainder of the forecast area, mainly after 4 PM.
While the main deep layer moist plume will remain south and east of
the forecast area tonight, the approach of the deep upper wave will
at least draw some decent mid level moisture back across Se Mi.
Strong forced ascent associated with the approaching upper wave will
interact with modest convective instability aloft to trigger a brief
yet fairly widespread convective response tonight, with showers and
possibly a fair amount of thunderstorms. The associated mid level dry
slot will support a period of dry conditions shortly before daybreak
Sunday. Low to mid level moisture will then quickly advance back
into the area after daybreak Sun. While the low level cold air
advection will not be too aggressive, the column looks to cool
quickly enough to support all snow showers by early Sun afternoon.
Relatively warm boundary layer temps (not to mention the strong
winds) will keep any accums to a minimum. The Lake Michigan response
looks to come into play Sunday afternoon. While this may support some
degree of enhancement to snow shower activity, the rapid departure
of the deep layer moisture Sun afternoon should limit potential snow
accums.

Despite the mid level flow transitioning toward a more zonal pattern
next week, the low level baroclinic zone will remain largely south of
the state through the first half of the week. This will keep temps
on the cool side of late February averages.

MARINE...

Impactful low pressure system will be taking shape across the
central plains this afternoon lifting northeast into the Straits by
Sunday morning and then into Quebec by Sunday night. Lighter east to
southeast flow at 10-20 kts will precede the low this afternoon.
Wind gusts increasing to near gales tonight along with likely rain
and thunderstorms chances. As the low reaches the Straits by Sunday
morning, winds will veer to the southwest then eventually to the
west behind a cold front Sunday afternoon. Expect sustained winds to
reach near gales with gusts approaching storm force by the afternoon
and into the overnight time frame. Storm Watch will remain in effect
for all of the Lake Huron basin and Lake St. Clair. High end gales
will be likely across western Lake Erie where a Gale Watch remains
in effect. Gale force winds will remain early Monday before pressure
gradient finally begins to weaken Monday afternoon as the low lifts
further to the northeast. Weaker northwesterly flow into the middle
of next week as high pressure drifts out of the northern plains and
into the region.

HYDROLOGY...

Strong winter storm expected to lift northeast out of the central
plains and through the Great Lakes tonight into Sunday. The track of
this low will place southeast Michigan in a region of warm and moist
advection. The result will be widespread rainfall along with
thunderstorm activity by this evening and overnight. PWATs
increasing to around 1" will aid in total rainfall amounts ranging
from 0.25 to 0.50 inches. Thunderstorm activity will allow potential
for higher localized rainfall amounts. Rainfall and warmer
temperatures will bring additional runoff from a melting snow pack.
However, the combined liquid amounts should be insufficient to cause
any significant flooding concerns.
