AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
336 PM CDT WED APR 16 2014

.SHORT TERM (TONIGHT THROUGH THURSDAY NIGHT)...
SOUTH TO SOUTHEASTERLY FLOW REMAINS INTACT ACROSS SOUTH CENTRAL
TEXAS THROUGH THE SHORT TERM PORTION OF THE FORECAST. THIS WILL LEAD
TO AN INCREASE IN MOISTURE AND CLOUD COVER THROUGH TONIGHT. UPSLOPE
SOUTHEASTERLY FLOW COULD PRODUCE SOME LIGHT DRIZZLE ACROSS THE HILL
COUNTRY...BUT WE HAVE LOW CONFIDENCE AND WILL NOT MENTION IN THE
FORECAST AT THIS TIME. SOME LIGHT SHOWERS MAY DEVELOP ON THURSDAY
FOR AREAS GENERALLY ALONG AND EAST OF I-35 GIVEN CONTINUED MOIST AIR
ADVECTION AND DAYTIME HEATING. IN ADDITION... A WEAK UPPER LEVEL
TROUGH TRANSLATING EASTWARD ACROSS NORTH TEXAS COULD AID IN THE
DEVELOPMENT OF LIGHT SHOWERS. A WEAK COLD FRONT WILL ALSO APPROACH
FROM THE NORTH LATE THURSDAY NIGHT AS THE ABOVE MENTIONED TROUGH
AXIS SHIFTS EAST OF TEXAS.

&&

.LONG TERM (FRIDAY THROUGH WEDNESDAY)...
THE ABOVE MENTIONED COLD FRONT WILL BRING A NORTHEAST TO EASTERLY
WIND SHIFT...BUT NO SIGNIFICANT COOLING DUE TO WEAK COLD AIR
ADVECTION BEHIND THE BOUNDARY. MID-LEVEL SHORTWAVE RIDGING WILL
BRIEFLY DEVELOP OVER TEXAS ON FRIDAY AS SURFACE WINDS TRANSITION TO
A MORE SOUTHEASTERLY DIRECTION. PRECIPITATION CHANCES BRIEFLY SHIFT
OUT WEST ALONG THE RIO GRANDE ON FRIDAY GIVEN THE PRESENCE OF A
LOW-LEVEL THERMAL RIDGE AXIS AND THE MID-LEVEL THETA-E RIDGE AXIS.
THE WEATHER PATTERN APPEARS TO BECOME INCREASINGLY ACTIVE ACROSS
TEXAS FOR THE UPCOMING WEEKEND. THE MEDIUM RANGE MODELS ARE NOW
SHOWING A DEEPER TROUGH APPROACHING FROM THE WEST WITH A FAIRLY
ACTIVE SOUTHWEST FLOW ALOFT PATTERN EXPECTED. THE PREVIOUS FORECAST
INCREASED RAIN CHANCES FOR MOST OF THE REGION AND BASED ON THE
LATEST MODEL GUIDANCE...WE SEE NO REASON TO ALTER AT THIS TIME.
THERE ARE SOME MODEL DIFFERENCES WITH REGARDS TO HOW QUICKLY THE
UPPER TROUGH MOVES EAST OF THE REGION. BASED ON THE LATEST GUIDANCE
SHOWING A SLOWER EASTWARD MOVEMENT OF THE TROUGH...WE DID EXTEND THE
MENTION OF SHOWERS AND THUNDERSTORMS INTO MONDAY FOR MOST AREAS.
WE/LL GO WITH A DRY AND WARM FORECAST FOR TUESDAY AND WEDNESDAY OF
NEXT WEEK...BUT WE/LL NEED TO MONITOR THE FAR NORTHWESTERN PORTION
OF THE CWA (VAL VERDE COUNTY) DUE TO POSSIBLE CONVECTION ALONG THE
DRYLINE.

&&

.FIRE WEATHER...
ELEVATED TO NEAR CRITICAL FIRE WEATHER CONDITIONS EXPECTED THIS
AFTERNOON ACROSS VAL VERDE COUNTY DUE TO GUSTY SOUTH WINDS AND LOW
HUMIDITIES. INCREASING MOISTURE IS EXPECTED ACROSS THE MENTIONED
REGION THIS EVENING...BUT WINDS WILL BE SLOW TO DECREASE.
