AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN
1145 AM CST FRI DEC 21 2007

.UPDATE...
UPDATED FOR 18Z AVIATION DISCUSSION BELOW.

&&

.DISCUSSION...
IN THE SHORT TERM...ADVECTION OF HIGHER DEW-POINT AIR ACROSS
MELTING SNOW PACK WILL RESULT IN PERSISTENT DENSE FOG OVER ABOUT
THE EASTERN TWO-THIRDS OF OUR CWA. CONSEQUENTLY...SO WE EXPANDED
OUR DENSE FOG ADVISORY IN TIME WHILE CUTTING OFF SOME WESTERN
COUNTIES FROM OUR ORIGINAL ADVISORY AREA.

LOOKING OUT FURTHER...A VERY SHARP SHORT WAVE OVER THE INTERIOR
WEST IS EXPECTED TO PUSH EASTWARD INTO OUR CWA ON SATURDAY AND
SUNDAY...TAKING ON A SHARP NEGATIVE TILT AS IT DOES. A PERIOD OF
VIGOROUS LIFT IS EXPECTED OVER OUR WISCONSIN COUNTIES LATE
SATURDAY THROUGH MIDDAY SUNDAY...WHICH WHEN VIEWED AGAINST
AVAILABLE MOISTURE SUGGESTS A DECENT POTENTIAL FOR A 4 TO 6 INCH
SNOW EVENT WITH CONSIDERABLE BLOWING AND DRIFTING ON SUNDAY AS THE
ASSOCIATED SURFACE LOW DEEPENS TO ABOUT 985 MB AS IT PASSES OVER
LAKE SUPERIOR. WE HAVE POSTED A WINTER STORM WATCH FOR SIX OF OUR
9 WISCONSIN COUNTIES. THE COLDEST DAY OF THE NEXT SEVEN WILL
LIKELY BE SUNDAY WHICH OUR WIND AND TEMPERATURES WILL COMBINE FOR
SUBZERO WIND CHILL READINGS.

&&

.AVIATION.../18Z TAF ISSUANCE/
MAIN CONCERNS CONT TO BE CIGS AND VSBYS UNDER THIS WARM/MOIST
ADVECTION REGIME. APPEARS TO BE STEADY STATE CONDITIONS THROUGH MUCH
OF SOUTHERN MN WITH IFR CONDS CONTINUING THROUGH PERIOD.  SHOULD SEE
VSBYS DECREASE DURING THE AFTERNOON PERIOD AS HIGHER DEWPOINTS
CONTINUE TO LIFT INTO CENTRAL MN.  ONLY REAL IMPROVEMENT WILL BE
WITH FROPA ACROSS THE WESTERN CWA SATURDAY MORNING AS COLDER AIR
ARRIVES...SNOW ENDS...WINDS INCREASE AND CEILINGS RISE TO MVFR.
BELIEVE AIRMASS WILL BE WARM ENOUGH FOR -DZ IN THE DENSE FOG AREAS
THIS EVENING AND OVERNIGHT AHEAD OF THE FRONT.  THEN A BRIEF MIX
POSSIBLE WITH FROPA...WHICH WOULD OCCUR AT MSP AROUND 12Z SAT...AND
KEAU AFTER 18Z SAT. INCREASING WINDS WILL BE NEXT CONCERN DURING THE
DAY SATURDAY INTO SUNDAY AS SURFACE LOW DEEPENS OVER THE GREAT LAKES
REGION.
