Area forecast discussion, Mar 1, 3:51 AM CST, 2 hours 19 minutes before
SOUTH CENTRAL TEXAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 351 AM CST THU MAR 1 2001 RAIN CHANCES CONTINUE TO INCREASE ALONG WITH RADAR ECHOES. A STRONG STORM IS MOVING THROUGH THE COASTAL BEND TO REMIND US NOT TO LET OUR GUARD DOWN, BUT MOST OF THE OVERRUNNING SHOWERS ARE HARDLY SIGNIFICANT SHOWERS. MOST AREAS SHOULD EXPECT TO SEE LIGHT TO MODERATE RAINFALL AMOUNTS OF 1/2 OR LESS TODAY AND THIS TYPE OF RAIN WILL LOOK TO CONTINUE THROUGH FRIDAY AFTERNOON. MODELS HAVE HAD A TOUGH GO OF PREDICTING SPECIFIC RAINFALL AREAS, BUT PATTERN OF UPPER LOW PASSING THROUGH SOUTH TX SUGGESTS BEST CHANCE FOR THUNDERSTORMS AND HEAVY RAIN TO BE FRIDAY NIGHT. WILL MENTION LOCALLY HEAVY RAINFALL IN THIS 4TH PERIOD BUT CONFIDENCE IS TOO LOW FOR MENTIONING IN PREVIOUS PERIODS COSIDERING THE LACK OF A MESOSCALE FOCUSING FEATURE. IN ANY EVENT WILL GO LIKELY TO CATEGORICAL ON POPS TODAY THROUGH FRIDAY NIGHT. TEMPERATURES OVER THE HILL COUNTRY APPEAR TO HAVE STABILIZED BETWEEN 33 AND 37 DEGREES OVER THE HILL COUNTRY EARLY THIS MORNING. COLD AIR WILL MODIFY THROUGH PRECIPITATION, BUT THE PROCESS WILL BE SLOW, SO WILL STAY BELOW GUIDANCE THROUGH TONIGHT IN THE EXTENDED, MRF/NOGAPS/CANADIAN ALL SPEED UP THE NEXT PACIFIC TROUGH TO SUGGEST MORE CLOUDS IN DAYS 6 AND 7. REST OF THE EXTENDED WILL LOOK SIMILAR TO THE PREVIOUS ISSUANCE. PRELIMS... AUS 044/042/052/046 8888 SA T 047/045/055/049 8888 DRT 048/045/055/047 7788 .EWX...NONE. 18/2
