NWS STORM PREDICTION CENTER NORMAN OK
1227 PM CST THU JAN 09 2025
AREAS AFFECTED...PORTIONS OF THE TEXAS PANHANDLE INTO NORTHWEST
OKLAHOMA
CONCERNING...HEAVY SNOW
VALID 091827Z - 092230Z
SUMMARY...A NEARLY STATIONARY BAND OF HEAVY SNOW WITH RATES AROUND
0.5-1 INCH PER HOUR (LOCALLY 1.5 INCH) SHOULD PERSIST ACROSS
PORTIONS OF THE TX PANHANDLE INTO NORTHWEST OK FOR MUCH OF THE
AFTERNOON.
DISCUSSION...THE LATEST RADAR DATA FROM KAMA DEPICTS AN INCREASINGLY
ORGANIZED BAND OF MODERATE TO LOCALLY HEAVY SNOW EXTENDING FROM THE
TX PANHANDLE INTO NORTHWEST OK. THIS ORGANIZED BAND IS LIKELY BEING
AIDED BY A STRENGTHENING LOW/MID-LEVEL FRONTOGENETIC CIRCULATION
AHEAD OF THE PRIMARY LARGE-SCALE TROUGH. GIVEN THE SLOW MOTION OF
THE TROUGH, AND AN EMBEDDED IMPULSE TRACKING EAST-NORTHEASTWARD
ACROSS THE TX SOUTH PLAINS (EVIDENT IN WV IMAGERY), THIS BAND SHOULD
REMAIN PERSISTENT AND NEARLY STATIONARY THROUGH MUCH OF THE
AFTERNOON. STEEP MIDLEVEL LAPSE RATES (SAMPLED BY EARLIER OBSERVED
SOUNDINGS) ARE LIKELY SUPPORTING A CONVECTIVE ENHANCEMENT TO
SNOWFALL RATES, AND RECENT VISIBLE SATELLITE IMAGERY CORROBORATES
THIS AS WELL. AS A RESULT, 0.5-1 INCH PER HOUR RATES (LOCALLY 1.5
INCH) SHOULD PERSIST UNDER THE CORE OF THE SNOW BAND BEFORE IT
BECOMES LESS ORGANIZED.
