EARLY THIS MORNING A FAST MOVING UPPER LEVEL SHORT WAVE TROUGH
CONTINUED TO PUSH SOUTHEAST ACROSS NORTH DAKOTA. SCATTERED LIGHT

SOUTHEASTERN NORTH DAKOTA. LIGHT SNOW AND FLURRIES WILL QUICKLY
TAPPER OFF SHORTLY AFTER SUNRISE. ONLY A LIGHT DUSTING IS
EXPECTED.

TONIGHT...ANOTHER WAVE IS EXPECTED TO MOVE ACROSS NORTH DAKOTA.
THIS WAVE LOOKS TO BE ACCOMPANIED BY A MORE ROBUST SURFACE LOW.
ALL OF THE MAJOR MODELS INDICATE THE CENTER OF THE SURFACE LOW
WILL TRACK ACROSS CENTRAL NORTH DAKOTA. THEREFORE...IT APPEARS
THERE IS A PRETTY GOOD CHANCE THAT MOST LOCATIONS WILL SEE AN
ADDITIONAL LIGHT DUSTING TO AS MUCH AS ONE INCH OF SNOW THROUGH
TONIGHT.

THE MAIN CONCERNS IN THE EXTENDED PERIOD INVOLVE THE STRONG WIND

DIMINISHING POPS IN THE RELATIVE WARM SECTOR OF THE LOW.

TO NORTHWEST WINDS WILL DEVELOP. GFS BUFKIT SOUNDINGS FOR DICKINSON

OVER 40 MPH. UPPED THE WINDS WEST OVER THE SUPERBLEND ON SATURDAY
