AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
607 AM EST SUN DEC 27 2009

.AVIATION...

SOUTHWEST FLOW IN ADVANCE OF LARGE UPPER LOW WILL CONTINUE TO FEED
LOW LEVEL MOISTURE AND OCCASIONAL SNOW SHOWERS INTO THE AREA TODAY
AS IT WOBBLES INTO THE CENTRAL GREAT LAKES. EXPECT PREVAILING VFR
WITH CIGS AOA 4000 FEET MUCH OF THE TIME TODAY...WITH BANDS OF SNOW
SHOWERS PRODUCING MVFR CIGS/VSBYS AT TIMES THIS MORNING AND AGAIN
LATE IN THE DAY. LOWER CEILINGS WILL BE POSSIBLE AFTER 00Z-03Z AS
WEST/SOUTHWEST FLOW ALLOWS FOR MORE ENHANCEMENT FROM LAKE MICHIGAN
AND BY THE END OF THIS FORECAST PERIOD...WOULD EXPECT WIDESPREAD
SNOW SHOWERS IN THIS FLOW JUST IN ADVANCE OF AN ARCTIC FRONT THAT
WILL SWEEP THROUGH THE AREA AFTER THE UPPER LOW PROGRESSES OFF TO
THE EAST/NORTHEAST.

&&

.PREV DISCUSSION...ISSUED 345 AM EST SUN DEC 27 2009

SHORT TERM...TODAY

AN LARGE ELONGATED UPPER LOW COMPRISED OF TWO DISTINCT VORTICITY
CENTERS WILL WOBBLE INTO THE REGION TODAY PRODUCING SNOW SHOWERS
FROM TIME TO TIME. LIFT FROM ONE OF THESE LOBES WILL LIFT NORTH OF
THE REGION EARLY THIS MORNING...BRINGING A PERIOD OF ONLY FLURRIES
OR SCATTERED LIGHT SNOW SHOWERS...BUT THE EFFECTS OF THE SECOND
CENTER WILL BEGIN TO SPREAD INTO THE REGION LATER THIS MORNING ON
INTO THE AFTERNOON...AND WILL GO WITH OCCASIONAL SNOW SHOWERS AS
MOST AREAS WILL RECEIVE AT LEAST A DUSTING DURING THE NEXT 12 HRS
WITH TOP ACCUMULATIONS UP TO AN INCH IN SOME AREAS. TEMPERATURES
WILL TOP OUT AROUND 30 DEGREES TODAY...WHICH IS ONLY A FEW DEGREES
BELOW NORMAL HIGH TEMPERATURES FOR LATE DECEMBER.

LONG TERM...

MODEL TRENDS TONIGHT SUPPORT A MORE DIRECT BLOW FROM THE ARCTIC
FRONT/UPPER WAVE/SHORTWAVE TROUGH SLIDING THROUGH THE CENTRAL GREAT
LAKES ON MONDAY. HAVE THUS RAMPED UP POPS TO NUMEROUS TO
CATEGORICAL...WITH FAIRLY HEALTHY LIFT INDICATED WITHIN THE
DENDRITIC SNOW GROWTH REGION...GOOD BURST OF 275-280 K ISENTROPIC
ASCENT...LOW STATIC STABILITY IN THE LOW LEVELS...AND 2 G/KG OF
SPECIFIC HUMIDITY NOTED AT 850 MB. THINKING MOST LOCATIONS WILL GET
A QUICK INCH OF SNOW...WITH TWO INCHES IN A FEW LOCATIONS (LIKELY
THUMB REGION).

MODEL CONSENSUS IS FOR 850 MB TEMPS TO FALL INTO THE NEGATIVE UPPER
TEENS MONDAY NIGHT...WITH 925 MB TEMPS FALLING TO -13 C OR SLIGHTLY
COLDER. WIND AND CLOUDS THROUGH MONDAY NIGHT ARE EXPECTED TO HOLD
MINS IN THE LOW/MID TEENS....WITH HIGH TEMPERATURES ONLY MAKING IT
INTO THE MID 20S ON TUESDAY WITH LIMITED MIXING AS SURFACE RIDGE
AXIS (EXTENDING FROM HIGH OVER THE OHIO VALLEY) MOVES IN FOR TUESDAY
NIGHT. AT THIS POINT...WILL CALL FOR MINS TO HOLD IN THE LOW TO MID
TEENS...AS LOW LEVEL WARM ADVECTION KICKS IN AFTER MIDNIGHT.

PER 00Z EUROPEAN/GFS...
INITIAL SPLIT FLOW PATTERN OVER THE CONUS DURING THE MID WEEK PERIOD
IS STILL FORECASTED TO UNDERGOING SOME AMPLIFICATION/PHASING BY THE
END OF THE WORK WEEK...WITH LONGWAVE TROUGH AXIS OVER THE EASTERN
CONUS RESULTING IN NORMAL TO BELOW NORMAL TEMPERATURES AND AT LEAST
SCATTERED SNOW SHOWERS.

MARINE...

AN ARCTIC FRONT DROPPING SOUTH THROUGH THE CENTRAL GREAT LAKES ON
MONDAY IS EXPECTED TO LEAD TO NORTHWEST GALES OVER THE OPEN WATERS
OF LAKE HURON...AS VERY COLD TEMPERATURES COMING OVER THE RELATIVELY
WARM WATERS LEAD TO EXCELLENT LOW LEVEL INSTABILITY AND SUBSEQUENT
GOOD WAVE GROWTH IN EXCESS OF 12 FEET. A FEW GUSTS TO GALE FORCE
WINDS ARE ALSO EXPECTED ALONG THE NEARSHORE WATERS OF LAKE
HURON...INCLUDING OUTER SAGINAW BAY. COLDER WATER AND ICE COVER OVER
INNER SAGINAW BAY...LAKE ST CLAIR AND LAKE ERIE ARE EXPECTED TO LEAD
TO A MORE STABLE ENVIRONMENT/LESS MIXING...AND FORECASTING WINDS TO
HOLD AROUND 25 KNOTS. IN ANY EVENT...WIND AND WAVES WILL SLOWLY BE
DECREASING AS WE HEAD INTO TUESDAY...AS A RIDGE OF HIGH PRESSURE
BUILDS IN FOR TUESDAY NIGHT.
