   MESOSCALE DISCUSSION 0100   NWS STORM PREDICTION CENTER NORMAN OK   0655 PM CST WED FEB 25 2015   AREAS AFFECTED...PORTIONS OF NRN SC AND CNTRL NC   CONCERNING...HEAVY SNOW    VALID 260055Z - 260700Z   SUMMARY...A RAIN/SNOW MIX ACROSS NRN SC SHOULD TRANSITION TO ALL   SNOW AND SHIFT NORTHEAST INTO CNTRL NC THROUGH 07Z. SNOWFALL RATES   OF 1 IN/HR WILL BE LIKELY...WITH LOCALLY HIGHER RATES POSSIBLE.   DISCUSSION...00Z SFC ANALYSIS INDICATES A LOW PRESSURE AREA OVER THE   NRN GULF OF MEXICO...AND A WEAKENING AREA OF HIGH PRESSURE ACROSS   ERN NC/VA. A SHORTWAVE TROUGH OVER THE LOWER MS RIVER VALLEY   EMBEDDED WITHIN BROADER TROUGHING ACROSS THE ERN TWO-THIRDS OF THE   CONUS WILL CONTINUE MOVING NEWD THROUGH THE OVERNIGHT HOURS. A BROAD   AREA OF PRECIPITATION ASSOCIATED WITH THE SHORTWAVE TROUGH AND SFC   LOW EXTENDS FROM MUCH OF THE DEEP SOUTH INTO NC/SC.   OBSERVATIONS ACROSS NRN SC AS OF 00Z INDICATE NEAR-FREEZING SFC   TEMPERATURES...AND RECENT NSSL MPING REPORTS INDICATE A RAIN/SNOW   MIX IS BEGINNING TO TRANSITION TO ALL SNOW AS DYNAMIC COOLING OF THE   LOW/MID-LEVELS CONTINUES. AS THIS PRECIPITATION MOVES NEWD INTO   CNTRL NC WHERE SFC TEMPERATURES REMAIN ABOVE FREEZING...   COOLING AND MOISTENING OF THE DRY SFC-700 MB LAYER EVIDENT IN THE   00Z GSO SOUNDING WILL OCCUR. THIS WILL SUPPORT A TRANSITION FROM A   RAIN/SNOW MIX TO ALL SNOW ACROSS CNTRL NC THROUGH 07Z. STRONG   LOW-LEVEL WAA AND FRONTOGENETICAL FORCING WILL SUPPORT HEAVY SNOW   WITH RATES OF 1 IN/HR LIKELY. BASED ON UPSTREAM OBSERVATIONS FROM   NRN MS/AL/GA...AND SREF PROBABILITIES...LOCALLY HIGHER SNOWFALL   RATES OF 2+ IN/HR WILL BE POSSIBLE.   ..GLEASON.. 02/26/2015   ATTN...WFO...RAH...RNK...CAE...GSP...
