..SYNOPSIS
H5 UPPER LOW SLOWLY MOVES TO THE EAST SOUTHEAST THIS AFTERNOON AND
EVENING, THUS REMOVING SYNOPTIC SUPPORT FOR ONGOING SNOW. THERE IS A
LOW CHANCE FOR SCATTERED MESOSCALE BANDS OF MODERATE SNOW HEADING
THROUGH THE EVENING HOURS, WITH CAMS SHOWING DEVELOPMENT IN AND
AROUND THE NORTHERN AND CENTRAL RED RIVER VALLEY. ADDITIONAL
ACCUMULATION POTENTIAL IS SOMEWHAT LOW; HOWEVER, VISIBILITY COULD BE
ADVERSELY IMPACTED BRIEFLY. WINDS GUSTS ARE EXPECTED TO SUBSIDE
LATE THIS AFTERNOON INTO THE EARLY EVENING HOURS; HOWEVER,
SUSTAINED NORTHWEST WINDS ARE EXPECTED TO CONTINUE OVERNIGHT IN
THE RANGE OF 10 TO 20 MPH.
HEADING INTO THE OVERNIGHT PERIOD, LIGHT SNOW SHOWERS AND FLURRIES
WILL SLOWLY AS THE LOW CONTINUES EASTWARD. ANY POTENTIAL CLEARING
FROM WEST TO EAST WILL BE SLOW, BUT GRADUALLY WE SHOULD SEE PARTLY
SUNNY SKIES THURSDAY AFTERNOON, MAINLY WEST OF THE RED RIVER VALLEY.
COLDER AIR IS EXPECTED TO CONTINUE SETTLING INTO THE AREA IN THE
COMING DAYS AS ANOTHER SYSTEM TRAVERSES THE AREA THIS WEEKEND. THIS
WILL BRING A CHANCE FOR ACCUMULATING SNOW TO PARTS OF THE REGION,
MAINLY ALONG AND NORTH OF HIGHWAY 200. THERE REMAINS SOME
UNCERTAINTY STILL, BUT THERE IS DECENT AGREEMENT AMONG ENSEMBLES
REGARDING THE DEVELOPMENT OF AN UPPER LOW THAT WILL MOVE ACROSS THE
SOUTHERN CANADIAN PLAINS AND INTO THE NORTHERN PLAINS. ACCUMULATION
POTENTIAL IS LIKELY TO CHANGE AS WE GET CLOSER, WITH CURRENT
PROBABILITIES SHOWING ABOUT A 70 PERCENT CHANCE FOR 1 INCH OR MORE
SNOW FROM HIGHWAY 2, NORTHWARD TO THE INTERNATIONAL BORDER.
FOLLOWING THIS SYSTEM, MUCH COLDER TEMPERATURES ARE SUPPORTED, WITH
HIGHS IN THE TEENS TO LOW 20S ON MONDAY AND LOWS IN THE SINGLE
DIGITS.

WHERE LIGHT SNOW IS LINGERING, AND THERE HAVE BEEN BRIEF REPORTS

MEASURABLE PRECIPITATION SHOULD COME TO AN END BY 03Z. WEST-
NORTHWEST WINDS CONTINUE TO DIMINISH AS STRONGER GRADIENT AND
WINDS ALOFT TRANSITION TO THE SOUTH AND SOUTHEAST OF THE REGION,
ENDING ANY LINGER BLOWING SNOW IMPACTS TO VISIBILITY AFTER 03Z.
A FEW FLURRIES (NON MEASURABLE SNOW SHOWERS) MAY LINGERING INTO
