IMMEDIATE ISSUE IS CURRENT SNOW SYSTEM MOVING THRU NORTH DAKOTA
INTO SOUTH DAKOTA AND MINNESOTA. SYSTEM BEHAVING ABOUT HAS PROGGED
FROM 24 HOURS AGO WITH MAIN SNOW BAND WILLISTON-MINOT TO
JAMESTOWN-VALLEY CITY TO WAHPETON-FERGUS FALLS. THE SHARP EASTERN
EDGE IS NOW VERY APPARENT AND LOOKS LIKE SNOW WILL STAY JUST WEST
OF DEVILS LAKE AND THE CITY OF FARGO...SO DID POP/WX GRIDDS TO
ACCOUNT FOR THIS SHARP NO SNOW TO SNOW LINE. REMOVED ANY POPS/WX
EAST OF SNOW BAND AS VERY DRY AIR SUB 700 MB WILL REMAIN OVER NE
ND INTO MOST OF NW MN THRU THE DAY. DID TRIM THE EASTERN COUNTIES
OF THE ADVISORY AREA IN AREAS WHERE NO SNOW IS EXPECTED...BUT KEPT
THE COUNTIES OF BENSON AND EDDY THROUGH BARNES AND CASS INTO
RICHLAND...WILKIN...WEST OTTER TAIL AND GRANT AND POINTS WEST IN
ADVISORY THRU 6 PM FRI. THIS ENDING TIME LIKELY TOO LONG BUT
WANTED DAYSHIFT TO LOOK OVER TRENDS AND WIND POTENTIAL BEFORE
CANCELLING EARLY. REGARDING WIND POTENTIAL MSAS SHOWS WEAKENING
SFC LOW BTWN DIK-BIS WITH MAIN LOW DOWN IN NRN NEBRASKA. GRADIENT
IS TIGHT OVER ERN MT AND FAR WRN ND INTO WRN SD BUT OVER ERN ND IN
SNOW BAND AREA WINDS NOT LIKELY TO GET GOING MUCH AS MAIN PRESSURE
RISES AND COLD ADVECTION WAY WEST OF THE LOCAL AREA. DID CONTINUE
PATCHY BLSN IDEA THIS AFTN AS CHC OF WIND GUSTS OVER 20 KTS...BUT
DONT EXPECT BLSN TO BE MUCH OF AN ISSUE AT ALL.

WEAK HIGH TO MOVE THRU THE AREA TONIGHT...BUT DEGREE OF CLEARING
IN QUESTION AS VORT LOBE TROUGH NOW OVER SASK WILL MOVE THRU WITH
A BAND OF CLOUDS LIKELY. A BIT MILDER SFC-850 MB AIRMASS OVER AREA
SATURDAY WITH LIGHT SOUTHWEST FLOW AND MIXED CLOUDS AND SUN. MOST
AREAS SHOULD SEE DOUBLE DIGITS WHICH HASNT BEEN TOO COMMON IN THE
LAST 45 DAYS. WEAK SHORT WAVE WILL DROP INTO NRN MN SAT
NIGHT...THEN SUNDAY SEE ANOTHER MILD DAY WITH TEMPS AGAIN
APPROACHING 20F IN MANY AREAS.  

MODELS ARE A BIT SLOWER AND WEAKER WITH SHORT WAVE THAT WILL DROP
SOUTH ON LEADING EDGE OF ARCTIC AIRMASS SUN NIGHT. MOST NOW DELAY
REAL COOLING TIL LATE SUNDAY NIGHT AND MONDAY MORNING AND SFC LOW
AND 850 MB WIND FIELDS ARE WEAKER TOO THUS MAKING THE THREAT FOR
BLOWING SNOW LESS.
