...ARCTIC COLD FRONT TO BLOW THROUGH...

.PERSISTENT WEAK TROUGHING OVER PORTIONS OF ONTARIO NORTH OF THE LAKE 
HURON AND LAKE SUPERIOR HAS KEPT THE ARCTIC AIR BOTTLED UP NORTH OF 
THE REGION THIS MORNING. WEAK WINDS ARE EXPECTED DURING THE NEXT 6 
HOURS OR SO. THIS WILL CHANGE VERY RAPIDLY BY MIDDAY WHEN AN ARCTIC 
COLD FRONT WILL PUSH STEADILY SOUTHWARD THROUGH LOWER MICHIGAN. THE 
ARCTIC AIR MASS IS FORECASTED TO FLOOD INTO THE NORTHERN LAKE HURON 
BASIN BY 18Z. COLD, UNSTABLE CONDITIONS THEN LEADS TO HIGH 
CONFIDENCE IN GALE FORCE WINDS ACROSS THE LAKE HURON BASIN. FAIRLY 
HIGH CONFIDENCE EXISTS THAT GALE FORCE WILL NOT IMPACT SAGINAW BAY. 
AGGRESSIVE NATURE OF COLD ADVECTION TONIGHT NECESSITATES A SMALL 
CRAFT ADVISORY FOR LAKE ST CLAIR AND THE MICHIGAN WATERS OF LAKE 
ERIE FROM 20Z THIS AFTERNOON THROUGH 14Z WEDNESDAY. MUCH QUIETER 
MARINE WEATHER IS FORECASTED FOR BOTH WEDNESDAY AND THE BEGINNING OF 
THURSDAY WITH SPRAWLING ARCTIC HIGH PRESSURE PARKED OVERHEAD.

...DECREASING WINDS THIS MORNING|...

.STABLE ARCTIC HIGH PRESSURE WILL BECOME PARKED OVER THE CENTRAL 
GREAT LAKES TODAY AND THURSDAY. NORTHERLY SURFACE WINDS WILL REMAIN 
SEASONABLY SUBDUED WITH A STABLE NEAR SURFACE ENVIRONMENT. SOUTHERLY 
FLOW WILL EMERGE AND THEN INCREASE LATE THURSDAY IN RESPONSE TO THE 
CENTER OF SURFACE HIGH PRESSURE BUILDING INTO THE MID ATLANTIC 
REGION. STRENGTHENING SOUTHWESTERLY GRADIENT FLOW WILL SUPPORT THE 
INCREASE IN WINDS PARTICULARLY FOR THE LAKE HURON BASIN. LATEST 
SIGNAL FROM MODEL CONSENSUS SUGGESTS A HIGH CONFIDENCE IN WIND GUSTS 
REACHING THE 25 TO 33 KNOT RANGE PARTICULARLY AFTER 00Z-FRIDAY. THE 
WIND FORECAST BECOMES MORE TRICKY FOR THE WEEKEND AS A WARM FRONT 
WILL LIFT INTO THE GREAT LAKES REGION BEFORE STALLING. SPECIFIC

Area Forecast Discussion
National Weather Service Detroit/Pontiac MI
329 PM EDT Mon Mar 20 2017

.DISCUSSION...

Strong PV anomaly tracking through Central Canada this afternoon,
skirting through the northern Great Lakes Tomorrow morning will
help usher in much colder air by Wednesday morning, as 850 mb temps
fall into the negative mid-upper teens (per 12z Euro).

In meantime, a much weaker upper wave (500 mb cold pool of -20 C)
to track through northern Lower Michigan early this evening. Deeper
moisture/instability south of the Michigan border this afternoon,
and convection has already fired up over northern Indiana, and bulk
of activity will continue to track off to the east-southeast, thus
calling into question how much coverage of activity slips north of
the Michigan border. None-the-less, there is good mid level (700-
500 mb) lapse rates with the upper wave and low level convergence
with cold front, thus potential scattered showers, even north of
I-69. Overall, inherited pops for this afternoon/early evening were
in good shape and will be making few if any changes, with most
activity over around or just after 00z.

Modest low level cold advection Tonight into Tomorrow, as surface
ridge builds into lower Michigan. With the cold advection and plenty
of insolation Tomorrow, mixing depths should make a run to 850 MB,
tapping into some stronger winds, with local probabilistic SREF
weighted guidance pointing to gusts of 20 to 25 knots at the
surface. North-South Temp Gradient, with Detroit and points south
likely reaching and slightly exceeding 50 degrees based
on 850 MB temps around -2 C at 21z Tuesday, with upper 40s north.

Strong and deeper surge of cold air arrives Tuesday evening, likely
maintaining some gustiness to the northwest winds. Will have to keep
an eye on Lake Huron for possible Lake Effect activity, as even 925
mb temps lower into the negative low-mid Teens. However,
looks like just enough westerly component from due north to keeps
bands offshore. By the time winds potentially become due
northerly, inversion heights will be very low with the massive
center of high pressure (1036-1040 mb) building over Central Great
Lakes on Wednesday. Regardless, still worthy of low chance pops
along the Eastern Thumb shoreline Tuesday night into Wednesday.

The arctic high pressure over the Great Lakes will continue to keep
dry weather around through Thursday as it moves off towards the
east.  The extended period then turns active as a low pressure
systems looks to move across the region.  A rain/snow mix is
possible as a warm front lifts across the area Thursday evening
before changing over to all rain as warmer air is drawn in on
Friday. Temperatures through the weekend will be near seasonal to
above seasonal.

&&

.MARINE...

Window for weak thunderstorm activity remains through late afternoon
across western Lake Erie.  Otherwise, marine conditions to remain
quiet through early Tuesday as winds increase modestly out of the
northwest.

Passage of a strong cold front will then drive a stronger wind
response Tuesday afternoon and evening.  Favorable environment will
emerge under strong cold air advection to support a solid increase
in northwest winds during this time.  This will lead to a period of
gales across a majority of the lake Huron waters.   Small craft
conditions for the remainder of the waters, as waves build over
southern Lake Huron.  Steady decrease in wind speed and gustiness
Wednesday as high pressure then builds back into the region.

.PREV DISCUSSION...
Issued at 107 PM EDT Mon Mar 20 2017

AVIATION...

Weak ascent working along an elevated warm front will maintain a
window for showers /mainly Detroit corridor/ late today, while
perpetuating a combination of VFR diurnal cu and a lower coverage of
MVFR stratus.  There remains a low probability for thunderstorms
with any activity, but confidence on occurrence remains too low to
include.  This moisture will exit to the east early tonight, with
developing light northerly flow encouraging a clearing sky across
the lowest 5000 ft overnight.

For DTW...Low probability for thunderstorms remains through late
afternoon.  Current radar trends suggest ongoing development
upstream will remain just south of DTW, potentially affecting
southern sections of the airspace.   Probability of occurrance at
DTW remains too low to include attm.

//DTW THRESHOLD PROBABILITIES...

*  High in ceilings below 5000 ft through the evening.  Low
   overnight.

*  Low for thunderstorm occurrance through late afternoon.
