AREAS AFFECTED...WEST TEXAS INTO NORTH CENTRAL TEXAS AND SOUTHERN
OKLAHOMA.
CONCERNING...WINTER MIXED PRECIPITATION
VALID 091242Z - 091515Z
SUMMARY...A MIX OF SNOW, FREEZING RAIN AND OCCASIONAL SLEET IS
EXPANDING FROM WEST TEXAS TO THE RED RIVER.
DISCUSSION...A PRECIPITATION SHIELD HAS EXPANDED ACROSS WEST TEXAS,
THE TEXAS PANHANDLE, AND SOUTHERN OKLAHOMA AS ISENTROPIC ASCENT
STRENGTHENS AHEAD OF AN APPROACHING MID-LEVEL TROUGH. MANY
OBSERVATION SITES ACROSS WEST TEXAS HAVE OBSERVED FREEZING RAIN THIS
MORNING WITH RELATIVELY LIGHT ACCUMULATION. HOWEVER, AS
PRECIPITATION INTENSIFIES, ISOLATED GREATER ACCUMULATION AMOUNTS
HAVE BEEN OBSERVED (KABI REPORTED 0.14 INCHES OF ICE ACCRETION
BETWEEN 11Z AND 12Z), WITH THIS LIKELY CONTINUING THROUGH THE
MORNING. WHILE SOME MIXED PHASE PRECIPITATION MAY OCCUR THIS MORNING
WHILE THE BOUNDARY LAYER IS MOISTENING ACROSS OKLAHOMA AND NORTH
TEXAS, EXPECT MOSTLY SNOW ACROSS THIS REGION BY MID-MORNING GIVEN
THE THERMAL PROFILE FROM THE KOUN 12Z RAOB. FARTHER SOUTH, EXPECT
FREEZING RAIN TO PERSIST THIS MORNING BEFORE TEMPERATURES SHOULD
RISE ABOVE FREEZING BY LATE MORNING AS LOW-LEVEL FLOW/WARM AIR
ADVECTION STRENGTHENS.
