ISSUED AT 1144 PM CST FRI JAN 30 2015

MVFR CIGS CONTINUE TO SPREAD ACROSS THE CWA...ALTHOUGH KGFK AND
KTVF HAVE BRIEFLY GONE UP TO VFR. THINK THIS WILL FILL BACK IN AS
THE STRATUS CONTINUES TO MOVE IN FROM THE NORTH. WILL HAVE TO
WATCH SOME CLEARING IN THE WINNIPEG AREA TO SEE HOW FAR SOUTH IT
MOVES BUT FOR NOW THINK WE WILL STAY MVFR THROUGH MID MORNING. WE
SHOULD SEE SOME BREAKING UP OF STRATUS BUT MID LEVEL CLOUDS WILL
BE MOVING IN AS THE NEXT SYSTEM APPROACHES THROUGH WESTERN ND.
WILL KEEP VFR CIGS IN THE 4000-7000 FT RANGE BUT EVENTUALLY
LOWERED CIGS A BIT AT KDVL AND KFAR TOWARDS THE END OF THE PERIOD
AS THEY WILL BE CLOSER TO THE SNOW BAND. NORTHWEST WINDS WILL
CONTINUE TO BE RATHER BREEZY WITH SOME GUSTS NEAR 20 KTS.
