AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DULUTH MN
431 AM CST TUE NOV 28 2006
.DISCUSSION...RADAR SHOWS PRECIPITATION INCREASING THIS MORNING IN
COVERAGE...AND INTENSITY. PRECIPITATION TYPE WILL BE FREEZING
RAIN...RAIN OR SOME SLEET IN OUR SOUTHERN ZONES...AND SNOW OR
FREEZING RAIN NORTH THIS MORNING.
MODELS CONTINUE TO BE IN GENERAL AGREEMENT...BUT DIFFER ON DETAILS
SUCH AS LOW LEVEL THERMAL STRUCTURE. WE ONCE AGAIN USED A
BLEND...BUT LEANED TOWARD THE COOLER GFS.
TEMPERATURES HAVE SLOWLY INCREASED THIS MORNING...AND WERE IN THE
LOWER TO MID 30S ALONG AND SOUTH OF A LINE FROM CASS LAKE TO THE
TWIN PORTS AND IN ALL OF NORTHWEST WISCONSIN. WE WILL CONTINUE THE
FREEZING RAIN ADVISORY FOR ALL AREAS UNTIL NOON...BUT MAY BE ABLE
TO CANCEL IT EARLY SOUTH OF THE CASS LAKE...TO TWIN PORTS AND
NORTHERN WISCONSIN AREA MENTIONED ABOVE. WE WILL CONTINUE TO
CLOSELY WATCH TEMPERATURES...AND SHOULD GET MORE REPORTS FROM
SPOTTERS ETC. OVER THE NEXT COUPLE HOURS. LIGHTING CHARTS SHOW
STRIKES OVER PARTS OF CENTRAL AND NORTHERN MINNESOTA...WITH MORE
WIDESPREAD CONVECTION MOVING UP THROUGH SOUTHWEST MINNESOTA.
PLENTY OF LIFT THIS MORNING INTO EARLY AFTERNOON...WITH CONTINUED WARM AIR
ADVECTION...AND WITH THE UPPER LOW PROGRESSING EAST. GFS IS
FORECASTING 40-50KT 850MB SOUTHERLY WINDS TODAY ACROSS OUR WESTERN
ZONES...AND KDLH VWP SHOWED 35 KT AT 10Z. FORECAST SOUNDINGS
SUGGEST THE PRECIPITATION SHOULD SWITCH OVER TO ALL RAIN FOR MOST
OF OUR CWA BY LATE MORNING OR EARLY AFTERNOON. THE EXCEPTION WILL
BE ACROSS KOOCHICHING COUNTY...OR PARTS OF THE COUNTY. STRONG LIFT
IN OUR WESTERN COUNTIES WILL KEEP TEMPERATURES SLIGHTLY
COOLER...AND THE FORECAST SOUNDINGS AT INL SHOWS MAINLY SNOW
EARLY...WITH WARMING ALOFT SUGGESTING MORE FREEZING RAIN AS THE
MORNING PROGRESSES. A SWITCH OVER TO MAINLY RAIN IS POSSIBLE FOR A
TIME...BUT THINK IT WILL BE MAINLY A FREEZING RAIN/SNOW EVENT FOR
KOOCHICHING COUNTY...AND WE CONTINUED THE WARNING FOR THAT AREA.
THE SURFACE LOW WILL LIFT NORTH TO NORTHEAST TODAY...THE GFS IS
FURTHER EAST WITH IT...AND THE PRECIPITATION WILL DIMINISH LATER
THIS AFTERNOON FROM SOUTH TO NORTH. THE NAM IS SLOWER BRINGING IN
THE COLD AIR TONIGHT...WHICH LENDS MORE SUPPORT TO THE GFS.
PRECIPITATION CHANCES WILL BE LOWER TONIGHT...WITH THE EXCEPTION
OF PARTS OF NORTHWEST WISCONSIN. SNOW WILL BECOME THE PREDOMINANT
PRECIP TYPE FROM WEST TO EAST TONIGHT INTO WEDNESDAY.
WE WILL INCREASE THE CHANCES FOR PRECIP ON WEDNESDAY...MAINLY OVER
NORTHWEST WISCONSIN. AN AREA OF STRONG FRONTOGENESIS WILL AFFECT
PARTS OF NW WISCONSIN DURING THE DAY WEDNESDAY. WE HAVE INCREASED
QPF AMOUNTS OVER NW WI...AND MAY HAVE TO FURTHER ONCE WE SEE WHERE
THE ENHANCED BAND OF PRECIP DEVELOPS. WE ALSO COULD SEE A GRAVITY
WAVE DEVELOP AND ENHANCE PRECIPITATION OVER PARTS OF
BAYFIELD...DOUGLAS AND PINE COUNTIES LATE TONIGHT INTO WEDNESDAY
AS GUSTY LOW LEVEL WINDS DEVELOP AND INVERSION LEVELS DROP. THIS
WILL ALSO BEAR A CLOSE WATCH.
MUCH COLDER TEMPERATURES ARE STILL EXPECTED BEHIND THE LOW. 850MB
TEMPERATURES DROP TO -15 TO -20C BY WEDNESDAY EVENING...AND WILL
REMAIN BELOW NORMAL INTO THE WEEKEND.
