AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
325 AM CST FRI FEB 27 2009

FORECAST FOCUS ON COLDER TEMPERATURES THROUGH THE WEEKEND...FAIRLY
DRY FORECAST INTO NEXT WEEK.

LATEST WATER VAPOR IMAGERY INDICATED A POTENT SHORTWAVE TROUGH
MOVING THROUGH SOUTHEAST MINNESOTA INTO SOUTHWEST WISCONSIN.
ANOTHER SHORTWAVE TROUGH WAS LOCATED OVER THE NORTHERN ROCKIES.
REGION WAS BETWEEN NORTHERN UPPER LEVEL JET STREAM OVER
CANADA...AND SOUTHERN JET OVER MAINLY THE SOUTHERN HALF OF THE
COUNTRY. AT THE SURFACE...STRONG SURFACE LOW PRESSURE SYSTEM WAS
MOVING NORTHEAST THROUGH LOWER MICHIGAN INTO LAKE HURON.

.TODAY THROUGH SATURDAY NIGHT...

WINTER WEATHER ADVISORY WILL BE CANCELLED...AS PRECIPITATION HAS
TURNED TO ALL SNOW...AND HAS DIMINISHED IN INTENSITY TO MAINLY
LIGHT SNOW AND FLURRIES.

SURFACE HIGH PRESSURE FROM SOUTH CENTRAL CANADA WILL MOVE
SOUTHEAST AND WEAKEN THROUGH THE REGION THROUGH SATURDAY NIGHT.
THIS FEATURE SHOULD BRING QUIET WEATHER TO MOST OF THE AREA.

ISOLATED LAKE EFFECT FLURRIES MAY OCCUR NEAR THE LAKESHORE
COUNTIES TONIGHT AND SATURDAY MORNING...AS NORTHEAST WINDS OCCUR
OVER THIS AREA. HOWEVER...DELTA T VALUES IN THE SURFACE TO 850MB
LAYER ARE AROUND 8 DEGREES CELSIUS...AND BOUNDARY LAYER WINDS ARE
BRISK. DRY AIRMASS ABOVE INVERSION AT 2000 FEET ALSO A
NEGATIVE...THUS JUST A FLURRY MENTION.

COLD AIR ADVECTION BEHIND DEPARTING LOW SHOULD BRING 1000/500MB
THICKNESS VALUES MAINLY IN THE MID 520S DKM RANGE. THIS SHOULD
RESULT IN BELOW NORMAL TEMPERATURES THROUGH THIS PERIOD. BRISK
WINDS EARLY TODAY SHOULD SLOWLY WEAKEN AS THE LOW MOVES AWAY.

ANOTHER HIGH MOVES SOUTHEAST THROUGH THE REGION SUNDAY AND SUNDAY
NIGHT. THIS SHOULD CONTINUE THE QUIET BUT COOL WEATHER ACROSS

LAKE EFFECT SNOW SHOWERS ARE POSSIBLE SUNDAY AFTERNOON AND
EVENING NEAR THE LAKE...WITH ONSHORE BOUNDARY LAYER WINDS AND
MODEST SURFACE TO 850MB DELTA T VALUES AROUND 12 DEGREES CELSIUS.
BOUNDARY LAYER MOISTURE IS QUESTIONABLE...SO WENT WITH A SLIGHT
CHANCE FOR NOW.

ADVECTION BRINGS MORE SEASONABLE TEMPERATURES INTO THE REGION. DRY
FORECAST UNTIL LATER IN THE WEEK...WITH SYSTEM MOVING NORTHEAST
THROUGH THE NORTHERN PLAINS AND UPPER MIDWEST.
