.UPDATE...
ISSUED AT 551 PM CST TUE DEC 16 2014

HIGH PRESSURE WILL DROP SLOWLY SOUTH ACROSS THE EASTERN DAKOTAS
AND MINNESOTA TONIGHT. LATEST NAM AND MESOSCALE MODELS INDICATE
LOW STRATUS WILL REMAIN ACROSS WESTERN NORTH DAKOTA THROUGH A GOOD
PORTION OF THE NIGHT AND MAYBE THROUGH WEDNESDAY ALSO. EASTERN
DAKOTAS INCLUDING JAMESTOWN WILL REMAIN MAINLY CLEAR. THUS
ADJUSTED TEMPERATURES A LITTLE HIGHER OVER WESTERN NORTH DAKOTA AS
THEY SHOULD REMAIN INSULATED TONIGHT. DROPPED LOWS A LITTLE OVER
EASTERN PORTIONS OF CENTRAL NORTH DAKOTA...CLOSEST TO THE COLD
HIGH. THE REMAINDER OF CENTRAL NORTH DAKOTA LOOKED REASONABLE FOR
NOW WITH LOWS IN THE SINGLE DIGITS ABOVE ZERO.

&&

.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY)
ISSUED AT 256 PM CST TUE DEC 16 2014

CURRENT SURFACE ANALYSIS PLACES HIGH STRETCHING THROUGH THE
EASTERN AND CENTRAL DAKOTAS WITH LOW OVER THE GREAT LAKES. UPPER
LEVEL ANALYSIS PLACES COMPACT LOW OVER NORTHERN MINNESOTA...WITH
RIDGE STRETCHING FROM THE SOUTHERN PLAINS INTO THE BIGHORNS. OVER
OUR AREA...BROAD SWATH OF LOW CLOUD COVER REMAINS OVER THE WESTERN
HALF OF NORTH DAKOTA WITH A FEW FLURRIES...WHILE CLEAR SKIES REMAIN
TO THE EAST.

FOR TONIGHT...EXPECT CLOUD COVER TO SLOWLY ERODE OVERNIGHT WITH
EXCEPTION OF SOUTHWEST NORTH DAKOTA WHERE LATEST GUIDANCE KEEPS
MOISTURE IN PLACE THROUGH THE NIGHT. A FEW FLURRIES WILL CONTINUE.

ON WEDNESDAY...A MAINLY QUIET DAY IS EXPECTED WITH CLOUDS
LINGERING OVER THE SOUTHWEST. A WEAK WAVE MOVING THROUGH THE FLOW
MAY SKIRT FAR SOUTHWEST NORTH DAKOTA SO HAVE CONTINUE SOME LOW
CHANCES FOR SNOW IN THE AFTERNOON...BUT EXPECT LITTLE IF ANY
ACCUMULATION IF ANYTHING DEVELOPS.

.LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY)
ISSUED AT 256 PM CST TUE DEC 16 2014

QUIET WEATHER THROUGH THE WEEKEND...ACTIVE WEATHER MAY RETURN
EARLY NEXT WEEK.

AFTER A COOL START TO THE WEEK...TEMPERATURES ARE EXPECTED TO
MODERATE ACROSS THE REGION BY THE WEEKEND WITH WIDESPREAD HIGHS IN
THE MID 20S TO UPPER 30S. THEREAFTER...NORTHWEST FLOW IS EXPECTED
TO SETUP AS THE PATTERN BECOMES MORE AMPLIFIED WITH A SIGNIFICANT
RIDGE ACROSS THE EASTERN PACIFIC. THIS COULD BRING A SERIES OF
SHORT WAVE TROUGHS THROUGH THE REGION EARLY NEXT WEEK. IF THIS
PATTERN VERIFIES THE CHRISTMAS HOLIDAY WEEK MAY BECOME RATHER
ACTIVE AND COLD.
