AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN
404 AM CST MON JAN 17 2011

.DISCUSSION...

COMPACT SHORT WAVE MOVING ESE THROUGH FAR SOUTHERN MN AND NORTHERN
IOWA...BUT WITH GOOD MOISTURE TRANSPORT/THETA E ADVECTION INTO
EAST CENTRAL MN AND WEST CENTRAL WISCONSIN WILL KEEP SNOW GOING
INTO MID MORNING INTO WI...BUT BRIEFLY ENDING FOR EAST CENTRAL AND
SOUTH CENTRAL MN. SPEED OF SYSTEM AND INCREASING SNOW RATIOS
LIMITING SNOW AMOUNTS, CURRENT FORECASTS SEEM OK WITH UP TO 3
INCHES OVER WEST CENTRAL WI. FORECAST SOUNDINGS OVER SW MN
CONTINUE TO SUGGEST A SLEET AND SNOW MIX AND POSSIBLY FREEZING
DRIZZLE YET THIS MORNING OR EARLY AFTERNOON SECOND WAVE DRIVING SE
FROM ND WILL NOT HAVE THE MOISTURE TO WORK WITH BUT A FEW AREAS OF
SOUTHERN MN COULD PICK UP ANOTHER INCH. THERE IS A CONCERN OF
BLOWING SNOW DEVELOPING OVER WEST CENTRAL AND SW MN AS THE COLD
ADVECTION AND PRES RISES DEVELOP LATE THIS AFTERNOON AND EVENING.
850 MB WINDS NOT THAT IMPRESSIVE THOUGH.

CERTAINLY SOME UNCERTAINTIES WITH THE THE REST OF THE
FORECAST...ESPECIALLY TEMPERATURES. THE STILL VERY ACTIVE NW FLOW
WILL AT LEAST BRING SOME CLOUDS THROUGH PARTS OF THE AREA WEDNESDAY
OR WEDNESDAY NIGHT. THE GFS AND NAM HAD BEEN BACK AND FORTH WITH
THIS SYSTEM AT LEAST BRUSHING FAR SOUTHERN MN. WILL KEEP THE
SLIGHT CHANCE GOING THE FAR SOUTH WED NIGHT. WITH THE SOMEWHAT
MODIFIED  ARCTIC HIGH AND DRY AIR IN PLACE...MIGHT BE HARD TO GET ANY
MEASURABLE. THERE DOES SEEM TO BE SOME AGREEMENT ON AN ARCTIC FRONT
DROPPING SOUTH ON THURSDAY AFTER THESE WAVES PASS THROUGH...SETTING
UP FOR A COLD MORNING ON FRIDAY. FOR POINTS IN THE EASTERN
CWA...THE LOWEST AND HIGHEST ENSEMBLE MEMBERS ARE SHOWING SUB ZERO
MIN TEMPERATURES FOR FRIDAY...ALTHOUGH A WIDE SPREAD. SAID SPREAD
IN TEMPS REMAINS HUGE FOR NEXT WEEKEND. THE EC/GFS/NAEFS DO SHOW
SOME WARM ADVECTION DEVELOPING FRIDAY NIGHT. WILL INTRODUCE A
SMALL CHANCE AT THIS POINT. SEEMS REASONABLE IF THERE IS GOING TO
BE MODERATION AT SOME POINT.

&&

.AVIATION.../06Z TAF ISSUANCE/

INCOMING SNOW CONTINUES TO BE THE PRIMARY CONCERN FOR THE TAFS ON
THIS MARTIN LUTHER KING JR. HOLIDAY. LIGHT TO MODERATE SNOW
CONTINUES TO EXPAND TO THE NORTHEAST FROM SOUTHWEST MN. VISIBILITY
HAS BEEN BRIEFLY IFR...BUT EXPECT TO SEE THAT EXPAND AS THE
MOISTURE ADVECTION INCREASES INTO SOUTH CENTRAL AND EAST CENTRAL
MN AND WEST CENTRAL WI BY AFTER 10Z. CEILINGS SHOULD REMAIN 1K TO
2K FT...ASIDE FROM SOME MORE ROBUST POCKETS OF SNOW...WHICH MAY
GET TO EAU. THE WAVE GENERATING THIS SNOW WILL MOVE TO THE EAST BY
LATE MORNING BEFORE ANOTHER WAVE MOVES IN BY AFTERNOON. IN
BETWEEN...DECREASING WINDS MAY ALLOW FOR SOME MVFR TO EVEN IFR FOG
AND CEILINGS TO FORM DUE TO INCREASED LOW-LEVEL MOISTURE. THERE
ALSO MAY BE SOME LIGHTER SNOW...COMBINING FOR VISIBILITY
RESTRICTIONS AT TIMES TO BE IFR. THE SNOW DURING THE AFTERNOON
WILL MAINLY FAVOR WESTERN AND SOUTHERN MN WITH SLIGHTLY MORE
MODERATE INTENSITY. AS THE SURFACE COLD FRONT MOVES THROUGH DURING
THE AFTERNOON AND INTO THE EARLY EVENING...THE NORTHWEST WINDS
WILL INCREASE LEADING TO SOME BLOWING SNOW...MOST FAVORABLE AT AXN
AND RWF. THIS COMBINED WITH FALLING SNOW MAY RESTRICT THE
VISIBILITY TO LIFR.

MSP...CONFIDENCE ON SNOW START TIME IS INCREASING...BUT MAY NEED
TO BE PUSHED BACK ANOTHER HOUR TO 09Z. THE GREATEST RATES ARE
FAVORED WITHIN THE TEMPO TIME WITH MODERATE CONFIDENCE.
CONFIDENCE THEN DECREASES FOR THE MID TO LATE MORNING INTO THE
AFTERNOON...DUE TO THE POSSIBILITY OF FOG. CLOUDS BELOW 1700 FT
LOOK LIKE A GIVEN BY 18Z. THE SNOW INTENSITY SHOULD DECREASE FOR A
WHILE...BEFORE INCREASING AGAIN IN THE LATER AFTERNOON. TOTAL
ACCUMULATION BY 15Z OF AROUND ONE INCH IS EXPECTED...AND THEN
ANOTHER HALF INCH DURING THE AFTERNOON.

RWF...THERE IS A CHANCE FOR FREEZING DRIZZLE FROM 09Z THROUGH 16Z.
IF IT TRANSPIRES...IT WILL BE LIGHT...BUT COULD STILL HAVE IMPACTS.
