MESOSCALE DISCUSSION 0007
NWS STORM PREDICTION CENTER NORMAN OK
0239 AM CST SAT JAN 03 2015

AREAS AFFECTED...NRN TX PANHANDLE/OK PANHANDLE/FAR NE NM

CONCERNING...HEAVY SNOW 

VALID 030839Z - 031345Z

SUMMARY...A BAND OF MODERATE TO HEAVY SNOW WILL CONTINUE TO MOVE NWD
ACROSS THE TX PANHANDLE AND NE NM INTO THE OK PANHANDLE THIS
MORNING. SNOWFALL RATES COULD REACH 1 INCH PER HOUR WITHIN THE MCD
AREA.

DISCUSSION...THE LATEST WATER-VAPOR IMAGERY SHOWS AN UPPER-LEVEL LOW
OVER SRN NM WITH A WELL-DEFINED DRY SLOT OVER MUCH OF WEST TX. A
BAND OF MID-LEVEL MOISTURE EXTENDS FROM JUST TO THE NORTH OF THE
UPPER-LEVEL LOW NEWD INTO THE NRN TX PANHANDLE WHERE THE LEFT EXIT
REGION OF A MID-LEVEL JET IS LOCATED. THIS FEATURE WILL HELP ENHANCE
LIFT ACROSS THE SRN HIGH PLAINS OVER THE NEXT FEW HOURS AS THE
UPPER-LEVEL LOW APPROACHES FROM THE SOUTHWEST. THE NAM AND ECMWF
SOLUTIONS SUGGEST THAT ISENTROPIC LIFT WILL INCREASE AFTER 12Z
ACROSS THE OK PANHANDLE. THIS SHOULD HELP SUSTAIN OR INCREASE
SNOWFALL RATES WITHIN THE BANDS ALREADY ONGOING. SNOWFALL RATES OF 1
INCH PER HOUR WILL BE POSSIBLE TO THE NORTH OF A SHARP DEFORMATION
ZONE FORECAST TO SET UP FROM NEAR DALHART EWD TO NEAR CANADIAN IN
THE NRN TX PANHANDLE AROUND DAYBREAK.
