AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
1114 AM EST SUN JAN 22 2012

.AVIATION...

//DISCUSSION...

IFR AND LOW MVFR CONDITIONS WILL CONTINUE TO DETERIORATE FROM SOUTH
TO NORTH THIS AFTERNOON AS THE EXPANSIVE STRATUS FIELD ON MORNING
SATELLITE IMAGERY IS DRAWN NORTH BY SOUTHERLY LOW LEVEL WINDS.
FURTHER DETERIORATION TO LIFR WILL BE POSSIBLE TONIGHT AS LOW
CEILINGS AND DRIZZLE BEGIN TO LIFT INTO THE AREA BY LATE THIS AFTERNOON.
WINDS WILL REMAIN SOUTHEASTERLY AROUND 10-15 KTS THROUGH THE NIGHT.
HOWEVER...THE WIND FIELD ABOVE THE SURFACE...MAINLY ABOVE 1KFT
AGL...WILL BECOME STRONGER AS LOW PRESSURE STRENGTHENS OVER THE
WESTERN GREAT LAKES. THESE WINDS ABOVE THE SURFACE WILL MAINLY BE
OUT OF THE S-SSW BETWEEN 180 AND 200 DEGREES. AT 2KFT AGL...WINDS
ARE FORECAST TO INCREASE TO AROUND 40KTS BY 3Z AND 50-60 KTS BY
ABOUT 10Z. A PERIOD OF SHOWERS AND POSSIBLY A COUPLE RUMBLES OF
THUNDER AND/OR A BRIEF HEAVY DOWNPOUR WILL SHIFT THROUGH LOWER MI
BETWEEN 10Z AND 15Z.

FOR DTW...CEILINGS WILL DROP TO 400 FEET OR LOWER AS THE INFLUX OF
LOW LEVEL MOISTURE CONTINUES THROUGH THE NIGHT. WIND SHEAR IS
FORECAST TO DEVELOP AHEAD OF A COLD FRONT TONIGHT ...MAINLY AFTER
03Z...AS LOW DEEPENS OVER THE WESTERN GREAT LAKES. RAIN SHOWERS AND
AN ISOLATED THUNDERSTORM WILL BE POSSIBLE BETWEEN 11Z AND 14Z.

//DTW THRESHOLD THREATS...

* HIGH CONFIDENCE IN CEILINGS BELOW 5000 FEET

* MEDIUM CONFIDENCE IN CIGS AND/OR VSBYS DROPPING BELOW 200 FT
AND/OR 1/2 SM AFTER 00Z

* LOW CONFIDENCE IN A THUNDERSTORM BETWEEN 11Z AND 13Z.

.PREV DISCUSSION...ISSUED 312 AM EST SUN JAN 22 2012

SHORT TERM...TODAY AND TONIGHT

THE MID LEVEL LONG WAVE TROUGH NOW OVER THE SOUTHERN ROCKIES IS
FORECAST TO BECOME NEGATIVELY TILTED AS IT LIFTS INTO THE CENTRAL
PLAINS TODAY...THEN DEVELOP INTO A CLOSED CIRCULATION OVER THE UPPER
MISSISSIPPI VALLEY TONIGHT. IN RESPONSE...LOW PRESSURE WILL TRACK
FROM THE LEE OF THE COLORADO ROCKIES THIS MORNING INTO THE WESTERN
GREAT LAKES BY EARLY MON MORNING. MEANWHILE...A 1034MB SFC HIGH WILL
REMAIN PARKED OVER NEW ENGLAND TODAY...WHICH WILL CAUSE A
STRENGTHENING IN THE S-SE LOW LEVEL FLOW ACROSS THE MISSISSIPPI
VALLEY AND GREAT LAKES REGION AS THE SFC LOW APPROACHES. THIS IN
TURN WILL LEAD TO A STRONG INFLUX OF GULF OF MEXICO MOISTURE INTO
THE GREAT LAKES REGION TONIGHT. IN FACT...BY 09Z MON...MODEL
SOUNDINGS INDICATE PRECIPITABLE WATER VALUES SURGING TO JUST OVER AN
INCH ACROSS SE MI.

SE MI WILL CONTINUE TO BE INFLUENCED BY THE LARGE ANTICYCLONE ACROSS
NEW ENGLAND TODAY...THUS LEAVING CONTINUED SOUTHEASTERLY SFC WINDS
ACROSS THE FORECAST AREA. THIS ALONG WITH THE FRESH SNOW COVER AND
EXPECTED INCREASE IN STRATUS WILL MAINTAIN A SHALLOW YET STABLE
BOUNDARY LAYER. SO DESPITE THE STRONG WARMING IN THE 925-700MB
LAYER...EXPECT ONLY A GRADUAL RISE IN SFC TEMPS INTO THE 30S BY LATE
AFTERNOON/EVENING. A STRENGTHENING LOW LEVEL JET FROM THE TENNESSEE
VALLEY INTO THE GREAT LAKES TONIGHT /925MB WINDS FCST TO RISE TO
50-60 KTS/ WILL BRING A MUCH STRONGER SURGE IN WARM AND MOIST LOW
LEVEL AIR INTO SE MI. THIS WILL LEAD TO A STEADY RISE IN TEMPS
THROUGH THE NIGHT...LIKELY EXCEEDING 40 DEGREES BY DAYBREAK MON.
MODEL SOUNDINGS THROUGH THE EVENING SUGGEST THE MOISTURE DEPTH WILL
REMAIN SHALLOW...SUPPORTING MAINLY SOME DRIZZLE AND FOG. THE PLUME
OF MUCH DEEPER MOISTURE IS NOT FORECAST TO ARRIVE INTO SE MI UNTIL
AFTER 06Z. MID LEVEL HEIGHT FALLS IN ADVANCE OF THIS MOISTURE PLUME
WILL CONTINUE TO WARRANT CATEGORICAL POPS ACROSS THE FORECAST AREA
LATE TONIGHT. THE PRECIP WILL BE OF A CONVECTIVE NATURE GIVEN THE
DEEP ELEVATED CONVECTIVE INSTABILITY SHOWN ON MODEL SOUNDINGS. THE
INSTABILITY MAY ACTUALLY BE SUFFICIENT TO TOUCH OFF SOME ELEVATED
THUNDERSTORMS.

LONG TERM...

THE BASE OF THE TROUGH/STRONG UPPER WAVE CURRENTLY MOVING THROUGH
THE FOUR CORNERS REGION WITH STRENGTHENING DEEP SOUTHWEST FLOW OVER
THE CENTRAL CONUS...ALLOWING FOR THE MILD AIRMASS TO MAKE GOOD
INROADS TO THE NORTH...AS 00Z RAOBS AT OAX INDICATED AN 850 MB TEMP
OF +5C. PREFERENCE WILL BE WITH THE SLOWER/FARTHER WEST SOLUTIONS OF
THE 00Z EUROPEAN/UKMET/CANADIAN MODELS. 850 MB TEMPS FORECASTED TO
RISE TO 6 C MONDAY MORNING BEFORE DROPPING SWIFTLY DURING THE
AFTERNOON. DRY SLOT LOOKS TO BE NARROW AND MOVE THROUGH FAIRLY
RAPIDLY...THUS ANY END TO THE PRECIPITATION LOOKS SHORT LIVED BEFORE
COLD CYCLONIC FLOW AND SECONDARY COLD FRONT ARRIVES...SUPPORTING A
ROUND OF SNOW SHOWERS MONDAY NIGHT. ALTHOUGH...WITH THE SYSTEM
TRACKING NORTH-NORTHEAST AT A GOOD CLIP...THE CHANCES FOR ANY
APPRECIABLE SNOW ACCUMULATIONS APPEAR LOW...AS AMOUNT OF COLD AIR
BEHIND THIS SYSTEM IS LIMITED AS WELL...AROUND -10 C...TEMPERING THE
LAKE MICHIGAN RESPONSE. WITH CLOUDS PERSISTING MONDAY
NIGHT...LOOKING FOR MINS TO ONLY FALL INTO THE MID 20S. TEMPS WILL
THUS BE IN GOOD SHAPE TO CLIMB ABOVE THE FREEZING MARK ON TUESDAY
(ASSUMING THERE IS SOME AFTERNOON SUN)...AND RIGHT THROUGH THE WORK WEEK
FOR THAT MATTER...AS POLAR VORTEX HOLDS NEAR SOUTHERN
ALASKA...SENDING PACIFIC ORIGIN AIRMASS THROUGH THE NORTHERN
CONUS...UNDERNEATH THE ENERGETIC QUASI ZONAL FLOW. BASED ON THE
CONSENSUS OF MEDIUM RANGE MODELS...A SHOT OF ARCTIC AIR WILL
ARRIVE FOR THE WEEKEND...AS UPPER LEVEL LOW OVER TEXAS PHASES WITH
THE NORTHERN STREAM...SPINNING UP A POTENTIAL EAST COAST STORM.

MARINE...

STRONG HIGH PRESSURE PARKED ACROSS NEW ENGLAND COMBINED WITH LOW
PRESSURE TRACKING INTO THE CENTRAL PLAINS TODAY WILL CAUSE AN
INCREASE IN THE SOUTHEASTERLY WINDS. THE RESIDUAL ARCTIC AIR OVER
LAKE HURON WILL LEAD TO UNSTABLE CONDITIONS OVER THE WATER RIGHT
INTO THIS EVENING. THIS MAY ALLOW WIND GUSTS TO APPROACH GALE FORCE
OVER THE OPEN WATERS. A WARM FRONT WILL THEN LIFT INTO GREAT LAKES
TONIGHT...WITH VERY MILD AIR PASSING ACROSS LAKE HURON OVERNIGHT
INTO MONDAY MORNING. THIS INCREASE IN STABILITY WILL SUPPRESS THE
POTENTIAL FOR GALES FORCE WINDS TO MAKE IT TO THE LAKE SURFACE
DESPITE DEEPENING OF THE SURFACE LOW. AREAS OF DENSE FOG WILL
HOWEVER BE OF CONCERN.

THE SURFACE LOW IS FORECAST TO TRACK ACROSS THE NORTHERN GREAT LAKES
ON MONDAY...BRINGING A STRONG COLD FRONT ACROSS LAKE HURON DURING
THE AFTERNOON. COLD AIR WILL ACTUALLY FILTER ACROSS THE LAKE FROM SW
TO NE. THE INCREASED INSTABILITY AS A RESULT OF THIS COLD AIR AND
CONTINUED DEEPENING OF THE SURFACE LOW AS IT LIFTS NORTHEAST WILL
LIKELY LEAD TO A PERIOD OF GALES MON AFTERNOON THROUGH MON NIGHT.
WINDS AND WAVES WILL THEN DEGREASE TUES NIGHT INTO WEDNESDAY AS HIGH
PRESSURE EXPANDS ACROSS THE SOUTHERN GREAT LAKES.
