TX AND OK PNHDLS WEATHER IS A CLOSED LOW OFF THE SRN CA COAST. OUR
FCST AREA WILL BE IN SW FLOW ALOFT...WHICH SUGGESTS AN EROSION OF THE

THRU TUESDAY. ALSO...ANY PRECIPITATION THAT FALLS TONIGHT THROUGH
MONDAY MORNING WILL LIKELY BE A WINTRY MIX OF EITHER LIGHT FREEZING
DRIZZLE...LIGHT FREEZING RAIN...OR LIGHT SLEET. BY MONDAY AFTERNOON
ENOUGH WARM AIR WILL BE PRESENT SUCH THAT ANY PRECIPITATION SHOULD BE
ALL LIQUID DURG THAT TIME. IT APPEARS THAT ONLY VERY LIGHT AMOUNTS OF
WINTRY PRECIPITATION ARE EXPECTED TONIGHT THRU MONDAY AFTERNOON. SLGT
CHC POPS WERE UTILIZED TONIGHT THRU MONDAY.

THE LAST IN THE SERIES OF STORM SYSTEMS WILL BE A FAST MOVING UPPER
LEVEL TROF AND ITS ATTENDANT SFC COLD FRONT. THESE TWO FEATURES ARE
PROGGED TO IMPACT THE TX AND OK PNHDLS DURG THE TUESDAY THRU
WEDNESDAY NIGHT TIME FRAME. COLDER TEMPERATURES AND A SMALL THREAT OF
