BUILDING INTO THE REGION FROM THE WEST.  THIS HIGH WILL SLIDE EAST

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
1239 PM EST THU JAN 20 2011

.AVIATION...

CONDITIONS OVER THE NEXT 24-36 HOURS WILL BE PRIMARILY
MVFR...HOWEVER THERE WILL BE TWO WINDOWS OF OPPORTUNITY TO SEE
VISIBILITIES FALL TO IFR IN SNOWFALL. THE FIRST WILL BE THIS
AFTERNOON AND EARLY EVENING (19-01Z) FROM PTK SOUTH AS A LOW
PRESSURE SYSTEM TRACKING ACROSS THE TENNESSEE VALLEY SPREADS LIGHT
SNOWFALL INTO FAR SOUTHEAST MICHIGAN. THE SECOND WILL BE ALONG THE
LEADING EDGE OF ARCTIC COLD FRONT THAT WILL SWEEP EASTWARD ACROSS
THE AREA THIS EVENING. EACH TERMINAL SITE SHOULD SEE A 2-4 HOUR
BURST OF SNOW ASSOCIATED WITH THE FRONTAL PASSAGE...WHICH WILL
POTENTIALLY DROP VISIBILITIES TO BETWEEN 1 AND 2 MILES. WINDS WILL
ALSO BACK TO THE WEST AND BECOME GUSTY BEHIND THE FRONT. BKN MVFR
CEILINGS AND GUSTY WINDS WILL THEN CONTINUE ON FRIDAY. TOTAL
ACCUMULATIONS TODAY AND TONIGHT SHOULD BE AROUND ONE INCH OR LESS.

&&

.PREV DISCUSSION...ISSUED 402 AM EST THU JAN 20 2011

SHORT TERM...TODAY

SCATTERED FLURRIES WILL DOT THE REGION...MAINLY FROM I 69 OR SO
SOUTH AS REMNANT LAKE EFFECT ACTIVITY DRIFTS EAST AS LOW LEVEL FLOW
BECOMES LIGHT WESTERLY. THIS WILL BE REPLACED BY THE NORTHERN EDGE
OF A STEADIER AREA OF LIGHT SNOW...WHICH WILL SPREAD NORTH TO AROUND
I 94 DURING THE AFTERNOON AS A SHORTWAVES PUSHES INTO THE CENTRAL
GREAT LAKES AND OHIO VALLEY. ACCUMULATIONS BEFORE 00Z WILL BE VERY
LIGHT...GENERALLY LESS THAN HALF AN INCH. TEMPERATURES WILL CLIMB
INTO THE LOWER/MID 20S AGAIN TODAY WITHIN BAND OF VERY WEAK WARM AIR
ADVECTION WITHIN SOUTHWEST FLOW IN ADVANCE OF APPROACHING ARCTIC
COLD FRONT.

LONG TERM...TONIGHT THROUGH WEDNESDAY

AN INTERESTING SETUP TONIGHT...FROM THE STANDPOINT THAT WE DON/T SEE
IT VERY OFTEN. THAT IS...A MATURE COLD FRONT COLLOCATED WITH A
TROUGH AXIS THAT IS CHANGING ORIENTATION TO A NEGATIVE TILT.
SO...WILL SEE A REASONABLY SHARP THERMAL DISCONTINUITY IN THE
PRESENCE OF A HEALTHY FRONTOGENETIC RESPONSE. PRECIPITATION TONIGHT
WILL BE LIMITED BY THE LACK OF DEPTH FOR ASCENT AND THE VERY SHORT
DURATION (2 TO 3 HRS) OF FGEN/POSTFRONTAL ISENTROPIC LIFT. FRONTAL
TIMING IS SET BETWEEN 3-7Z TONIGHT. BEST CONVERGENCE AHEAD OF
FRONTAL BULGE SHOULD TAKE PLACE ACROSS THE NORTHEASTERN CWA. MOST
AREAS TONIGHT WILL SEE A HALF INCH OF SNOWFALL WHILE THE THUMB
REGION MAY SQUEEZE OUT AN INCH. TEMPERATURE RESPONSE IMMEDIATELY
BEHIND THE FRONT WILL BE NOTEWORTHY...WITH RAW MODEL OUTPUT
SUGGESTING THAT TEMPERATURES MAY FALL SOME 7 OR 8 DEGREES INTO THE
THE LOWER TEENS ABOVE ZERO. POSTFRONTAL WESTERLIES BEHIND THE FRONT
WILL GET GUSTY...RANGING BETWEEN 25 AND 30 MPH...WHICH SHOULD SEND
WIND CHILLS DOWN TO 5 AND 10 DEGREES BELOW ZERO.

DESPITE STEEPENING LOW LEVEL LAPSE RATES FRIDAY...STOUT ISENTROPIC
DOWNGLIDE IS ANTICIPATED. THIS WILL LIKELY SQUASH PRECIPITATION
POTENTIAL OUTSIDE OF CENTRAL LOWER MICHIGAN AND THE TIP OF THE
THUMB. SOLID COLD AIR ADVECTION DURING THE DAY WILL LIMIT HIGHS IN
THE LOWER TEENS ALL AREAS...WIND CHILLS REMAINING BELOW ZERO.

A WEAKENED SURFACE RIDGE IS FORECASTED TO PIVOT THROUGH LOWER MICHIGAN
FRIDAY NIGHT. THIS WILL MAKE THE LOW FORECAST EXTREMELY
TRICKY...ESPECIALLY CONSIDERING THAT VERY LIGHT WAA WILL BE UNDERWAY
AMIDST THE THREAT OF LAKE CLOUDS. OUT OF RESPECT FOR THE GENERAL
AIRMASS...DID LOWER THE MINIMUM TEMPERATURE FORECAST FOR MUCH OF THE
SOUTHERN CWA. THE FORECAST IS LIKELY TOO STRONG WITH WINDS FRIDAY
NIGHT...NOCTURNAL RESPONSE WILL BE QUICKER IN DIMINISHING WINDS.
THUS...WIND CHILLS ARE A LITTLE TOO AGGRESSIVE...BUT READINGS WILL
LIKELY TOUCH 10 DEGREES BELOW ZERO FOR A TIME DURING THE EVENING.

THE NEXT CLIPPER SYSTEM IS EXPECTED TO DROP INTO LOWER MICHIGAN
SATURDAY/SATURDAY NIGHT. THE MODELS ARE ALL OVER BOARD WITH REGARDS
TO PLACEMENT AND TIMING. NAM IS TOO DEVELOPED OVER THE LAKES REGION
WHILE THE GFS APPEARS TO WEAK WITH THE SURFACE REFLECTION HERE.
THERMODYNAMICS DO NOT LOOK FAVORABLE WITH A STABLE COLUMN BETWEEN
900-500MB...ANY SNOWFALL ACCUMULATIONS WOULD BE MEASURED AT A FEW
TENTHS OR LESS.

IN FAMILIAR FASHION...A SURFACE ANTICYCLONE IS EXPECTED TO QUICKLY
SWING THROUGH LOWER MICHIGAN FOR SUNDAY AND MONDAY. THIS ALL BUT
ENSURES BELOW NORMAL TEMPERATURES BOTH SUNDAY AND MONDAY WITH LITTLE
IN THE WAY OF PRECIPITATION POTENTIAL.

MARINE...

WEST/SOUTHWEST WINDS WILL REMAIN RELATIVELY WEAK TODAY WITH WAVES
EBBING INTO THIS EVENING. HOWEVER...THE NEXT SURGE OF ARCTIC AIR
WILL RACE THROUGH THE AREA THURSDAY NIGHT INTO FRIDAY...BRINGING
MUCH STRONGER WINDS WHICH WILL VEER FROM WEST TO NORTHWEST WITH
TIME. WILL BE ISSUING A GALE WARNING FROM LATE THURSDAY NIGHT INTO
FRIDAY FOR NORTHERN LAKE HURON AS THE MAIN SURGE OF COLD AIR IN THE
WAKE OF THE FRONT PUSHES THROUGH THE REGION. HIGH PRESSURE RETURNS
ON FRIDAY NIGHT AND BRINGS A RETURN TO MORE TRANQUIL CONDITIONS.
