.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z SATURDAY EVENING)
ISSUED AT 645 PM CST FRI JAN 30 2015

DRY AIR UNDER THE SFC TROUGH AXIS HAS KEPT KFAR AND KGFK VFR...BUT
SAT LOOP SHOWS THE LOWER CIGS COMING IN QUICKLY FROM THE
NORTHWEST. THE MVFR STRATUS IMPACTING KDVL CURRENTLY WAS LAGGING
BEHIND THE WIND SHIFT TO THE NORTHWEST A BIT. THINK THAT ALL TAF
SITES SHOULD BE MVFR BY 03Z THIS EVENING AS THE STRATUS COMES INTO
THE REGION. THE KTVF AND POSSIBLY KBJI COULD SEE A BRIEF BREAK
BETWEEN WARM AIR ADVECTION STRATUS AND THE CLOUDS BEHIND THE COLD
FRONT...BUT IT WILL BE SHORT LIVED. THE MVFR CIGS WILL CONTINUE
THROUGH TOMORROW MORNING BEFORE COMING UP TO THE 4000-10000 FT
RANGE. ANOTHER WEAK SHORTWAVE COULD BRING SOME SNOW TO CENTRAL ND.
NOT SURE IF IT WILL BE FAR ENOUGH NORTH AND EAST TO IMPACT THE TAF
SITES...SO KEPT EVERYWHERE DRY FOR NOW. BUT DID DROP KDVL BACK
DOWN TO MVFR TOMORROW AFTERNOON AS THE PRECIP COMES CLOSE TO THAT
AREA. WINDS WILL SHIFT AROUND THE NORTHWEST AT 10 TO 20 KTS.
