MESOSCALE DISCUSSION 2108
 NWS STORM PREDICTION CENTER NORMAN OK
 1211 PM CST SAT NOV 10 2012
 
AREAS AFFECTED...WRN SD...S-CNTRL ND...FAR NWRN NEB
 
CONCERNING...HEAVY SNOW

VALID 101811Z - 102215Z
 
SUMMARY...BAND OF MODERATE TO OCCASIONALLY HEAVY SNOWFALL IS
 EXPECTED TO PERSIST AS IT MOVES EWD ACROSS WRN SD...S-CNTRL ND AND
 FAR NWRN NEB. SNOWFALL RATES IN EXCESS OF 1 INCH/HR ARE LIKELY WITH
 THE POSSIBILITY OF BRIEF PERIODS OF 2 INCHES/HR.
 
DISCUSSION...SURFACE ANALYSIS DEPICTS A BROAD AREA OF LOW PRESSURE
 EXTENDING FROM SWRN CO NEWD INTO ERN SD/FAR WRN MN. TWO SURFACE LOWS
 ARE LOCATED WITHIN THIS BROAD AREA...ONE CENTERED OVER SWRN CO AND
 THE OTHER OVER E-CNTRL SD. RECENT RADAR IMAGERY AND SURFACE
 OBSERVATIONS INDICATE PERIODS OF MODERATE/HEAVY SNOW WITHIN A BAND
 ORIENTED SW TO NE ACROSS WRN SD. ALSO OF NOTE...THE MODEL GUIDANCE
 WAS TOO SLOW WITH THE ONSET OF THIS BAND.

SURFACE THETA-E FIELDS SHOW A WARM AIR ADVECTION NOSE FROM CNTRL IA
 NWWD INTO CNTRL SD. THIS TRAJECTORY FAVORS ADDITIONAL MOIST
 ADVECTION INTO THE REGION. STRONG FRONTOGENESIS IS ONGOING ACROSS
 CNTRL NEB WITH THE FAR NORTHERN PORTION OF THE AGEOSTROPHIC
 CIRCULATION LIKELY PHASING WITH LARGE SCALE LIFT ASSOCIATED WITH THE
 EXIT REGION OF A STRONG JET STREAK /CURRENTLY EXTENDING FROM NWRN NM
 NEWD INTO WRN NEB/. THESE DYNAMICS SHOULD FAVOR THE CONTINUATION OF
 THE SNOW BAND WITH THE POTENTIAL FOR SOME INTENSIFICATION AS IT
 MOVES EWD. SNOWFALL RATES IN EXCESS OF 1 INCH/HOUR WITH BRIEF
 PERIODS OF 2 INCHES/HOUR ARE ANTICIPATED.

These bad girls can be very nasty and bring tornado outbreaks and blizzards at the same time.

Plains and Midwest could get hit hard.

Stay tuned for updates.
