..SYNOPSIS
TODAY: COLD FRONT CONTINUES TO MOVE ACROSS THE REGION THIS MORNING,
WITH TEMPERATURES IN LOWER TEENS IN THE DEVILS LAKE BASIN AND IN THE
LOWER 20S IN THE SOUTHERN RED RIVER VALLEY. LIGHT SNOW IS FALLING AT
TIMES, MAINLY EAST OF THE RED RIVER, WITH ONLY ISOLATED SNOW SHOWERS
TO THE WEST. BLOWING AND DRIFTING SNOW WILL BE A CONCERN, ESPECIALLY
IN OPEN AREAS THROUGH MUCH OF THE MORNING AND INTO THE EARLY
AFTERNOON.
SUNDAY ONWARD: FLOW TRANSITIONS FROM NORTHWESTERLY TO ZONAL LATE
SUNDAY AND INTO NEXT WEEK. LOW LEVEL CHINOOK WINDS OUT OF THE WEST
WILL HELP BRING TEMPERATURES TO THE 20S AND 30S FOR DAYTIME HIGHS.
WINDY CONDITIONS ARE EXPECTED BOTH SUNDAY AND MONDAY AS OUR WESTERLY
CHINOOK WINDS PUMP IN WARM AIR TOWARDS EASTERN NORTH DAKOTA AND
NORTHWESTERN MINNESOTA. WIND GUSTS UP TO 35MPH ARE POSSIBLE DURING
BOTH AFTERNOONS. SLICK TRAVEL CONDITIONS ARE POSSIBLE FROM DRIFTING
SNOW BOTH SUNDAY AND MONDAY. IF HEADED OUT MONITOR THE LATEST
CONDITIONS ACROSS THE AREA. OTHERWISE, TEMPERATURES WILL BE WELL
ABOVE NORMAL ACROSS THE AREA, WITH HIGHS PEAKING ON MONDAY IN THE
MID TO UPPER 30S. SOME AREAS NEAR THE SHEYENNE RIVER VALLEY HAVE THE
POTENTIAL TO REACH THE LOWER 40S IF SKIES CAN CLEAR OUT FASTER IN
THE AFTERNOON HOURS.
A QUICK SYSTEM MOVES THROUGH ONTARIO MIDWEEK CLIPPING PORTIONS OF
THE AREA. PRECIPITATION TYPE IS EXPECTED TO BE SNOW, WITH THE MAIN
AREA OF SYNOPTIC FORCING TOWARD THE ARROWHEAD OF MINNESOTA.
TEMPERATURES MODERATE MID WEEK AS THE WESTERLY WINDS SUBSIDE SLOWLY,
WITH HIGHS IN THE 20S TO LOWER 30S. NEAR THE END OF THE WEEK THERE
ARE INDICATIONS OF FURTHER CHINOOK STYLE WESTERLY WINDS HELPING TO
INCREASE TEMPERATURES ONCE AGAIN, WITH THE INTRODUCTION OF FURTHER
UPPER LEVEL WAVES MOVING OUT OF THE ROCKIES.
..BLOWING AND DRIFTING SNOW TODAY
NORTHWEST WINDS HAVE INCREASED, FOLLOWING THIS MORNING'S COLD
FRONT, RANGING FROM 20 TO 25 MPH WITH GUSTS TO NEAR 40 MPH THUS
FAR THIS MORNING. THIS IS LEADING TO VISIBILITY REDUCTIONS AS
LOW AS 1/4 MILE IN OPEN AREAS, WITH SEVERAL OBSERVATION SITES
REPORTING PREVAILING VISIBILITY OF 3/4 MILE TO 1 1/2 MILES. THE
STRONGEST WINDS TODAY ARE EXPECTED TO IMPACT AREAS WEST OF THE
RED RIVER AS WELL AS THE NORTHERN RED RIVER VALLEY, WHERE
PRESSURE RISES ARE GREATEST FOLLOWING THE SHORTWAVE PASSAGE.
TRAVEL IMPACTS ARE POSSIBLE, ESPECIALLY IN OPEN AREAS ACROSS THE
DEVILS LAKE BASIN, NORTHERN RED RIVER VALLEY AND FAR NORTHWEST
MINNESOTA.

LOWERED CEILINGS ARE FORECAST WITHIN THIS TAF PERIOD.
STRONG COLD FRONT MOVES THROUGH TONIGHT SHIFTING WESTERLY WINDS

NORTH DAKOTA INTO THE RED RIVER VALLEY, INCLUDING KDVL, KGFK,
KFAR, AND KTVF. SCATTERED SNOW SHOWERS WILL ACCOMPANY THE FRONT,
