AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
355 AM CST MON JAN 26 2015

.SHORT TERM (TODAY THROUGH TUESDAY)...
UNSEASONABLY STRONG UPPER LEVEL RIDGING AND DOWNSLOPING SURFACE
WINDS ALONG WITH SLOWLY INCREASING THICKNESSES AND BOUNDARY LAYER
TEMPERATURES WILL CONTINUE THE WARMING TREND. HIGH TEMPERATURES
WILL BE WELL ABOVE THE AVERAGE FOR LATE JANUARY. LOW TEMPERATURES
WILL ONLY BE SLIGHTLY ABOVE AVERAGE AS DEWPOINTS REMAIN LOW WITH
LIGHT WINDS.

&&

.LONG TERM (TUESDAY NIGHT THROUGH SUNDAY)...
THE SHORT TERM PATTERN CONTINUES INTO WEDNESDAY NIGHT. A PATTERN
CHANGE BEGINS ON THURSDAY WHEN AN UPPER LEVEL TROUGH MOVING ACROSS
THE PLAINS FORCES A COLD FRONT THROUGH SOUTH CENTRAL TEXAS DURING
THE AFTERNOON. HIGHS ON THURSDAY WILL ONLY BE SLIGHTLY COOLER AS
COLD ADVECTION WAITS UNTIL THE EVENING. AN UPPER LEVEL TROUGH
CURRENTLY ALONG 140 WEST LONGITUDE IN THE PACIFIC APPROACHES THE
WEST COAST ON FRIDAY. WEAK OVERRUNNING AND ISENTROPIC LIFT
DEVELOPS AHEAD OF THE TROUGH ON FRIDAY WITH SLIGHT CHANCES OF RAIN
RETURNING TO OUR WESTERN AREAS. THERE IS SOME UNCERTAINTY WITH THE
DETAILS OF THE PATTERN THIS WEEKEND INTO NEXT WEEK. THERE ARE
QUESTIONS ON FRONTAL POSITION...UPPER LEVEL PIECES OF ENERGY...AS
WELL AS WHEN AND IF THE TROUGH DEVELOPS INTO A CLOSED LOW AND
WHEN IT OPENS UP AND MOVES EAST. FOR NOW...WILL MAINTAIN ONGOING
FORECAST WITH RAIN CHANCES INCREASING FRIDAY NIGHT...PEAKING ON
SATURDAY INTO SATURDAY NIGHT AS THE FRONT MOVES BACK NORTH INTO
PARTS OF SOUTH CENTRAL TEXAS...AND THEN DECREASING SUNDAY INTO
SUNDAY NIGHT AS THE FRONT RESUMES IT TRACK SOUTH TO OFF THE COAST.
THERE COULD AGAIN BE SOME HEAVIER RAINS SATURDAY INTO SATURDAY
NIGHT AS UNSEASONABLY HIGH PWS IN THE 1.2 TO 1.6 INCH RANGE ARE
FORECAST. THE GFS HAS TRENDED A LITTLE WARMER. HOWEVER...WILL
CONTINUE THE COOLER TEMPERATURES ALREADY FORECAST DUE TO CLOUDS
AND RAIN. CHANGES MAY BE POSSIBLE TO THE FORECAST AS THE RAINFALL
EVENT GETS CLOSER AND SOUNDING NETWORKS BETTER ABLE TO CAPTURE THE
ATMOSPHERIC FEATURES.
