CONCERNING...PRECIPITATION TRENDS...WINTER PRECIPITATION 

VALID 020553Z - 021200Z

A BURST OF MODERATE SNOW IS EXPECTED WITHIN THE THREAT AREA OVER
EXTREME NERN OK/EXTREME NWRN AR/EXTREME SWRN MO BEGINNING FROM SW TO
NE NEAR 09Z.  

INTENSIFYING ASCENT ASSOCIATED WITH APPROACHING JET STREAK AND SHORT
WAVE TROUGH WILL COMBINE WITH COOLER EARLY MORNING TEMPERATURES AND
SOME LOCAL TRAPPED COOLER AIR WITHIN HIGHER TERRAIN TO SUPPORT LOCAL
MODERATE SNOW. AREAS EXPERIENCING MIXED PRECIPITATION MAY SWITCH TO
ALL SNOW WITHIN MORE INTENSE PRECIPITATION BANDS.  NAM AND RUC
FORECASTS BOTH SUGGEST MOST INTENSE UPPER LEVEL FORCING WILL
OVERSPREAD THE THREAT AREA AFTER 09Z.  ETA MICROPHYSICS SUGGEST
PRECIPITATION IS LIKELY TO BE ALL SNOW WITHIN THIS AREA OF MORE
INTENSE FORCING.
