Area forecast discussion, May 6, 2:25 PM CDT, 4 hours 20 minutes before
COASTAL BEND FORECAST DISCUSSION NATIONAL WEATHER SERVICE CORPUS CHRISTI TX 225 PM CDT SUN MAY 6 2001 MAIN QUESTION IS WHETHER TO KEEP FFA GOING WHERE HEAVIEST RAIN OCCURRED YESTERDAY. CURRENT VISIBILE SATELLITE AND RADAR SHOWING RELATIVELY BENIGN CONDITIONS OVER CWFA WITH RESPECT TO YESTERDAY. STORMS ARE FIRING UP WELL TO THE NORTH IN BIG COUNTRY...AND WEST OVER MEXICO WHERE INSTABILITY AND THETA-E AXIS RESIDE. AT THIS TIME...FEEL POTENTIAL FOR RAIN OVER THE SATURATED AREAS WILL HAVE TO COME FROM THE STORMS WHICH FORM NORTH AND WEST OF AREA...THEN ADVECT INTO AREA LATER TONIGHT AS ALL FOCUS AND ENERGY IS TO THE NORTH. WITH LOW LEVEL WIND FIELD RELATIVELY WEAK AND CONFLUENT FLOW ALOFT...THIS MAY BE HARD TO DO THIS FAR EAST AS 850MG-300MB THICKNESS GENERALLY SHOW WEST TO EAST MOTION. THUS...CONFIDENCE FOR RAIN OVER AREA CHANCE AT THIS TIME. WILL WRITE AN SPS TO HIGHLIGHT POTENTIAL...BUT WITH POPS AOB 30% WILL NOT ISSUE FFA AT THIS TIME. SINCE CONVECTION IF IT GETS THAT FAR...WILL BE OVERNIGHT WITH LIMITED WIND FIELD...WILL ALSO DO THE SAME WITH THE MENTION OF SEVERE. HOWEVER...IF RADAR LIGHTS UP IN THE NEXT HOUR...THEN WILL GO THE OTHER WAY AS SEVERAL HOURS OF HEATING TO GO AND CAPES HIGH. SPS WILL HANDLE BOTH. ELSEWHERE...WILL KEEP THE POPS THE HIGHEST OVER WEST AND NORTH... WHERE BEST POTENTIAL IS BASED ON INSTABILITY AXIS AND THETA-E RIDGE...AND DECREASE OVER THE EAST. INSTABLITY REMAINS HIGH FOR TOMORROW BUT ONLY FOCUS WILL BE SEA-BREEZE INTERACTION AND THUS...POPS HIGHEST NORTH AND WEST AGAIN. WEAK FRONT MAY TOUCH OUR NORTHERN ZONES TUESDAY BUT WILL GENERALLY BE TOO WEAK TO BE A PLAYER IN ANY ADDITIONAL CONVECTION. RIDGE BUILDS IN AFTER TUESDAY SO NO RAIN EXPECTED. POSSIBLE FRONT APPROACHING FRIDAY MAY BRING A CHANCE OF RAIN. SATURDAY AND SUNDAY LOOK DRY. PRELIMS...1ST PERIOD CHANGES POSSIBLE BASED ON LAST MINUTE TRENDS...

UPPER RIDGE BUILDS OVER THE AREA BY MID WEEK...SO WILL KEEP MAR FORECAST DRY AFTER MONDAY. .CRP...NONE. 86/GW...84/JMC

TXZ229>234-239-247-070400- THUNDERSTORM OUTLOOK NATIONAL WEATHER SERVICE CORPUS CHRISTI TX 401 PM CDT SUN MAY 6 2001 ...A CHANCE OF SHOWERS AND THUNDERSTORMS LATER TONIGHT MAINLY OVER THE RIO GRANDE PLAINS AND NORTHERN COASTAL BEND... ISOLATED SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP LATE THIS AFTERNOON AND EARLY THIS EVENING...MAINLY OVER THE RIO GRANDE PLAINS. HOWEVER...THESE STORMS SHOULD DISSIPATE AN HOUR OR TWO AFTER SUNSET. ADDITIONALLY...SHOWERS AND THUNDERSTORMS...DEVELOPING OVER CENTRAL TEXAS AND NORTHEASTERN NEW MEXICO LATE THIS AFTERNOON...WILL CONTINUE TO DEVELOP THROUGH THE EVENING HOURS. SOME OF THESE SHOWERS AND THUNDERSTORMS COULD MOVE INTO THE RIO GRANDE PLAINS LATER THIS EVENING. IF THE SHOWERS AND THUNDERSTORMS MAINTAIN THEMSELVES...THEY WILL MOVE INTO THE NORTHERN COASTAL BEND AND VICTORIA CROSSROADS AFTER MIDNIGHT. SINCE THESE SHOWERS AND THUNDERSTORMS WILL MOVE INTO THE AREA MAINLY AFTER MIDNIGHT...WITH THE LOSS OF DAYTIME HEATING AND AN UNFAVORABLE WIND FIELD...THE POTENTIAL FOR SEVERE THUNDERSTORMS WILL BE LIMITED. HOWEVER...AN ISOLATED STORM COULD APPROACH SEVERE LIMITS...PRODUCING WINDS NEAR 55 MPH AND HAIL AROUND THE SIZE OF DIMES. FURTHER EAST OVER THE VICTORIA CROSSROADS...THERE IS A SLIGHT CHANCE OF SHOWERS OR THUNDERSTORMS...MAINLY AFTER MIDNIGHT. AGAIN...WITH THE LACK OF DAYTIME HEATING SEVERE WEATHER IS NOT LIKELY...ALTHOUGH AN ISOLATED STORM COULD APPROACH SEVERE LIMITS.
