AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DULUTH MN
930 PM CST FRI FEB 2 2007

.DISCUSSION...ZONES/GRIDS HAVE JUST BEEN UPDATED TO ACCOUNT FOR
ONLY SOME MINOR CHANGES. REGARDING TEMPS...HAVE DROPPED TEMPS A
FEW DEGREES IN SPOTS. SOME OF THE ROAD WEATHER/RAWS SITES HAVE
MIDDLE TEENS BELOW ZERO ALREADY UP NORTH. WINDS HAVE STARTED TO
PICK UP IN TEH WESTERN CWA AND THEY SHOULD CONTINUE TO PICK UP AS
THE NIGHT WEARS ON...GENERALLY 10 TO 15 MPH BUT SOME HIGHER GUSTS.
WIND CHILLS SHOULD RESPOND ACCORDINGLY...AND ARE ALREADY IN THE 20
TO 30 BELOW RANGE IN SPOTS.

A VERY INTERESTING CONVERGENCE BAND OF SNOW NOW SNAKING ACROSS
NORTHERN BAYFIELD COUNTY...FROM NEAR PORT WING TO JUST NORTH OF
BAYFIELD. SOME 23 DBZ REFLECTIVITIES IN THIS AND...WHICH HAS BEEN
FAIRLY STATIONARY DURING THE EVENING. HAVE ADDED 1-3 INCH
ACCUMULATIONS IN THIS AREA TONIGHT...BUT WILL HAVE TO WATCH
CLOSELY IN CASE THE BAND CONTINUES TO STRENGTHEN. INITIAL THOUGHT
IS THAT THE BAND SHOULD BREAK UP SOMEWHAT AND BECOME MORE
DISORGANIZED AS OVERALL WINDS SHIFT TO THE NORTHWEST AND LOW-MID
LEVEL SHEAR INCREASES.

OTHERWISE...EVERYTHING ELSE LOOKS GOOD. DID DROP CLOUD COVER A BIT
TOO AS THERE ARE QUITE A FEW HOLES IN BETWEEN SNOW SHOWERS/BANDS.
