AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
326 PM CDT THU JUN 24 2004

.DISCUSSION...
WET PATTERN TO CONTINUE THROUGH MUCH OF THE FORECAST CYCLE. SOLAR
HEATING AND SURFACE BOUNDARIES HAVE ALLOWED SCATTERED CONVECTION TO
DEVELOP WITH SOME LOCALLY HEAVY DOWNPOURS. THIS CONVECTION SHOULD
SLOWLY DISSIPATE WITH SUNSET. MEANWHILE, SHORT-WAVE TROUGH AND SPEED
MAX NEAR THE BIG BEND WILL ALLOW CONVECTION OVER THE HIGHER TERRAIN
TO DEVELOP INTO AN MCS AND PROPAGATE TO THE SOUTHEAST INTO THE CWA
DURING THE LATE EVENING AND OVERNIGHT HOURS. EXPECT HEAVIER RAINS
WITH THIS. HOWEVER, FOR NOW, WILL HOLD OFF ON ISSUING FLOOD WATCH AS
STILL SOME DISPUTE ON IF MCS WILL DEVELOP AND/OR MOVE INTO CWA, PLUS
FORWARD SPEED MAY PRECLUDE SIGNIFICANT ACCUMULATIONS.

REMAINDER OF THE FORECAST CYCLE, A MID AND UPPER LEVEL TROUGH WILL
PERSIST OVER OR JUST WEST OF TEXAS. WITH SHORT-WAVES AND SPEED MAXES
MOVING THROUGH MEAN TROUGH POSITION AND NEAR TROPICAL PWS, CONVECTION
COULD DEVELOP JUST ABOUT ANY TIME, ALTHOUGH GREATEST CHANCES WILL BE
DURING THE DAY DUE TO SOLAR HEATING. ANY SURFACE BOUNDARIES WILL
ENHANCE RAINFALL. A FLOOD WATCH MAY HAVE TO BE ISSUED DURING THE NEXT
FEW DAYS, AS FEATURES BECOME BETTER DEFINED. BY THE MIDDLE TO LATE
NEXT, MODELS SUGGEST SUBTROPICAL RIDGE WILL BUILD WEST INTO TEXAS AND
NORTHEASTERN MEXICO, SLOWLY DECREASING RAIN CHANCES. DAYTIME
TEMPERATURES TO BE BELOW AVERAGE DUE TO CLOUDS, RAIN, AND SOIL
MOISTURE.
