What happened

The episode as NWS FGF wrote it up.

A Colorado Low, located over the central Rockies on the evening of March 9th, tracked northeast to northern Wisconsin by the evening of the 10th. One swath of heavier snow fell on the 9th, mainly from Jamestown (ND) to Mayville (ND) to Red Lake Falls (MN). Snowfall amounts of 6 to 8 inches fell along this narrow band. Outside of this band, about 2 to 4 inches of snow were reported. As the system wrapped up on the 10th, a much wider swath of snow fell, along with increasing north winds. The most snow was reported along the initial snow band, with total amounts ranging from 10 to 13 inches. Outside this area, total snowfall amounts ranged from 4 to 8 inches. Maximum north wind gusts during the height of the blizzard ranged from 40 to 50 mph. Interstate 94 was closed from Moorhead to Fergus Falls, where large drifts were reported. Most schools closed early on Monday (9th), then remained closed on Tuesday and Wednesday.

230 PM CDT MON MAR 9 2009

.DISCUSSION...
FORECAST CHALLENGE CONCERNS VARIOUS HEADLINES REQUIRED NEXT 24-36
HOURS.

MODELS OVERALL CONTINUE TO COME INTO AGREEMENT WITH NEXT SYSTEM. GFS
HAS BEEN MOST CONSISTENT AND WILL USE FOR DETAILS.

SNOW BAND CONTINUES TO BISECT FA FROM SW-NE. THIS IS ORIENTED ALONG
AREA OF ENHANCED FRONTOGENETIC FORCING OVER BAROCLINIC RIBBON. BOTH GFS
AND NAM LIFT MAIN FORCING NE AND WEAKEN IT LATE AFTERNOON INTO THIS
EVENING. AT THIS POINT FEEL VALID TIME STILL LOOKS REASONABLE SO
WILL KEEP ADVISORY GOING. LOOKS TO BE A BREAK FROM MID EVENING ON
BEFORE NEXT WAVE BEGINS TO IMPACT FA TUESDAY. COLD ADVECTION
CONTINUES OVERNIGHT AND AM SEEING SOME PRETTY COLD READINGS UP
STREAM. TIGHT THERMAL GRADIENT WILL CONTINUE OVERNIGHT BUT MIXING
AND CLOUD COVER WILL MINIMIZE DROP. WILL GO COLDEST OVER FAR NW
WHERE SOME CLEARING POSSIBLE. AS FAR AS HEADLINES WILL BEGIN WINTER
WX ADVISORY OVER DVL BASIN INTO NORTHERN VALLEY AT 06Z AS
COMBINATION OF WIND AND TEMPERATURES SHOULD ALLOW WIND CHILL
CRITERIA TO BE MET.

SURFACE LOW OVER CENTRAL HIGH PLAINS WILL LIFT NE TO GREAT LAKES BY
TUESDAY NIGHT. ISENTROPIC LIFT INCREASES AGAIN BY 12Z WITH 3-4GM/KG
MIXING RATIOS LIFTING INTO SE THIRD OF FA DURING DAY. TRACK OF
850-700MB LOW ALSO FOCUSES MAXIMUM SNOW POTENTIAL THIS AREA. LESSER
AMOUNT EXPECTED AS YOU GO NORTH AND WEST WITH DVL BASIN AND NORTHERN
VALLEY LIKELY TO ONLY PICK UP A FEW INCHES. EQUALLY IMPORTANT WILL
BE WIND POTENTIAL. WINDS TO INCREASE TO 30-35KT THROUGH MIXED LAYER
WITH STRONGEST WINDS EXPECTED FROM 18Z ON. ACTUAL WIND SPEED MAY BE
JUST BLO BLIZZARD CRITERIA HOWEVER WITH SNOWFALL TODAY AND EXPECTED
SNOW TOMORROW WILL DEFINITELY HAVE WHITE OUT POTENTIAL IN OPEN AREA.
FOR THIS WILL UPGRADE TO BLIZZARD WARNING FROM CENTRAL VALLEY
SOUTHWARD AND ADJACENT AREAS. FAR EASTERN FA TO SEE LESS WIND SO
WILL GO WINTER STORM WARNING THIS AREA. WILL KEEP ADVISORY GOING
OVER DVL BASIN INTO NORTHERN VALLEY WITH COMBINATION OF HAZARDOUS
WIND CHILLS AND SOME BLOWING AND DRIFTING.

SNOW TO GRADUALLY DIMINISH FROM W-E TUESDAY NIGHT AND WILL ALLOW
BLIZZARD WARNING TO EXPIRE BUT WILL LIKELY NEED TO TRANSITION TO
WIND CHILL HEADLINES. IMPROVING CONDITIONS WEDNESDAY HOWEVER
TEMPERATURES WILL BE VERY COLD CONSIDERING TIME OF YEAR AND WIND
CHILLS WILL CONTINUE TO BE AN ISSUE.

TEMPERATURES WED NIGHT WILL HINGE ON DEGREE OF MIXING/WARM ADVECTION
AND SURFACE HIGH DROPS SOUTH OF FA. NEVER THE LESS TEMPERATURES WILL
BE WELL BLO AVERAGE.

THURSDAY WILL SEE SOME RECOVERY IN TEMPERATURES WITH SURFACE SW
FLOW/WARM ADVECTION AND SOLAR BUT STILL BLO AVERAGE.

.LONG TERM (FRI-TUE)...
LONG RANGE MODELS START OUT PRETTY SIMILAR IN TIMING AND TRACK OF
WEATHER SYSTEMS THROUGH THE N PLAINS...AND THEN START TO DIVERGE
TOWARD THE END OF THE EXTENDED FORECAST...ESPECIALLY IN TIMING.
THEREFORE...ENDED UP KEEPING FORECAST CONTINUITY BY USING A BLEND OF
THE GFS AND ECMWF.

A 500MB RIDGE STARTS BUILDING INTO THE N PLAINS FOR THE WEEKEND...
KEEPING THE AREA DRY...WITH TEMPERATURES RISING TO NEAR NORMAL. THEN
ON SUN NIGHT AND MON...AN AREA OF LOW PRESSURE MOVES OUT OF THE
ROCKIES AND THROUGH S CANADA...DRAGGING A COLD FRONT THROUGH THE N
PLAINS ALONG WITH A 500MB TROF. THUS...INCLUDED A CHANCE FOR SNOW IN
THE FORECAST FOR MON.
