CHALLENGING FORECAST AHEAD. THE SURFACE COLD FRONT WAS LOCATED
ROUGHLY FROM CLOVIS TO DIMMITT TO HAPPY TO JUST SOUTH OF GAGE. THE
FRONT HAS BEEN MOVING SLOWLY SOUTHWARD WITH TEMPERATURES DROPPING 10
DEGREES IN ONE HOUR AT FRIONA. BEGINNING TO SEE MORE BREAKS IN THE
CLOUDS ACROSS THE WESTERN AND SOUTH CENTRAL COUNTIES OF THE FA EARLY
THIS AFTERNOON.

POTENT UPPER LEVEL LOW CONTINUES TO SPIN OVER THE GREAT BASIN
CAUSING SOUTHWEST FLOW ALOFT ACROSS WEST TEXAS. WITH SUCH A STRONG
SYSTEM TO THE WEST...THE COLD FRONT CURRENTLY ACROSS THE NORTHERN FA
SHOULD BEGIN TO LIFT BACK NORTHWARD TONIGHT. HOWEVER...THIS SCENARIO
MAY NOT HAPPEN IF CONVECTION OVER THE NW FA BEGINS AND PUSHES THE
FRONT FURTHER SOUTH RICH LOW LEVEL MOISTURE REMAIN IN PLACE ACROSS
THE REGION WITH LARGE SCALE LIFT ASSOCIATED WITH STRONG UPPER SYSTEM
OUT WEST. EXPECT RAIN CHANCES TO CONTINUE WITH SOME STORMS BECOMING
SEVERE LATE THIS AFTERNOON AND EVENING. SEE SWODY1 AND SWOMCD.

THE UPPER LOW AND ASSOCIATED TROUGH WILL GET KICKED TO THE EAST
TONIGHT AND TRACK ACROSS COLORADO TOMORROW. THIS SHOULD CAUSE THE
SFC TROUGH TO DEEPEN OVER THE PANHANDLES THURSDAY. MID LEVELS OF THE
ATMOSPHERE BEGIN TO DRY RAPIDLY FROM WEST TO EAST LATE THURSDAY
AFTERNOON. LATER THURSDAY EVENING THE PACIFIC FRONT WILL MOVE
RAPIDLY ACROSS THE SOUTH PLAINS. THE RESULT SHOULD BE AN INCREASE IN
WIND SPEEDS MAINLY AFTER MIDNIGHT THURSDAY INTO MID DAY FRIDAY.
PARTS OF THE EASTERN FA COULD SEE SHOWERS AND A FEW THUNDERSTORMS
AHEAD OF THE FRONT.

THE KICKER SYSTEM DIVES DOWN THE WEST COAST THURSDAY NIGHT AND
EVENTUALLY CUTS OFF OVER NORTHERN BAJA/SOUTHERN CALIFORNIA. THE NEXT
COLD FRONT WILL MOVE INTO THE AREA EARLY SUNDAY BRINGING A SLIGHT
CHANCE OF RAIN THROUGH MONDAY. THE ACTUAL SPEED OF THIS SYSTEM IS
STILL IN QUESTION AT THIS TIME.
