ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS WILL OCCUR THIS AFTERNOON AND TONIGHT. PERIODS OF MODERATE TO HEAVY RAINFALL WITH LOCALIZED FLOODING WILL BE POSSIBLE. DRIER CONDITIONS ARE EXPECTED TUESDAY THROUGH THURSDAY AS THE MOISTURE PLUME SHIFTS TO THE WEST. MOISTURE WILL RETURN TO THE REGION BY THE END OF THE WEEK FOR ISOLATED TO SCATTERED THUNDERSTORMS NEXT WEEKEND. TEMPERATURES WILL REMAIN NEAR OR SLIGHTLY ABOVE SEASONAL AVERAGES THROUGH THE WEEK. && .DISCUSSION... ABUNDANT MOISTURE WILL FUEL SCATTERED SHOWERS AND THUNDERSTORMS THE REST OF THIS AFTERNOON AND TONIGHT. THUNDERSTORMS WILL BECOME MORE ISOLATED OVER EASTERN PORTIONS OF THE FORECAST AREA AS DEEPER MOISTURE SHIFTS TO THE WEST. PERIODS OF MODERATE TO HEAVY RAINFALL WILL WITH LOCALIZED FLOODING ALONG DRAINAGES...ARROYOS AND LOW WATER CROSSINGS NEAR STRONGER STORMS. WIND GUSTS UP TO 45 MPH AND SMALL HAIL WILL ALSO BE POSSIBLE THROUGH TONIGHT. STARTING TOMORROW...HIGH PRESSURE LOCATED TO OUR EAST WILL SHIFT CLOSER TO THE AREA. THIS WILL FORCE THE MOISTURE PLUME TO FURTHER TO THE WEST INTO ARIZONA. THE COMBINATION OF REDUCED MOISTURE AND INCREASED SUBSIDENCE FROM THE HIGH WILL SUPPRESS MOST THUNDERSTORM ACTIVITY ACROSS THE AREA FOR TUESDAY THROUGH THURSDAY. THE LOCAL AREA WILL BE UNDER A STEADY SOUTHEAST FLOW...WHICH WILL BE A DRY FLOW FOR A CHANGE. RESIDUAL MOISTURE AND MOUNTAIN TERRAIN EFFECTS WILL STILL RESULT IN ISOLATED THUNDERSTORM DEVELOPMENT OVER THE MOUNTAINS IN THE AFTERNOON EACH DAY. TEMPERATURES WILL REMAIN CONSISTENT THROUGH THE PERIOD WITH AFTERNOON HIGHS RUNNING A FEW DEGREES ABOVE NORMAL...BUT 100 DEGREE DAYS ARE NOT EXPECTED. MOISTURE WILL GRADUALLY BECOME MORE ENTRAINED WITHIN THE HIGH CIRCULATION BY THE END OF THE WEEK. THIS WILL RESULT IN A RISE IN THUNDERSTORM ACTIVITY TO A MORE ISOLATED LOWLAND AND SCATTERED MOUNTAIN COVERAGE PATTERN FOR FRIDAY THROUGH NEXT SUNDAY. TEMPERATURES WILL REMAIN CONSISTENT. && .AVIATION...VALID 11/00Z-12/00Z...HIGH PRESSURE SITUATED OVER CENTRAL TEXAS MONDAY AFTERNOON...WILL CONTINUE TO SLOWLY MIGRATE WESTWARD TOWARDS SOUTHERN NEW MEXICO. THIS WILL RE-DIRECT CIRCULATION OF SUB TROPICAL MOISTURE AND ATTENDANT STORM MOVEMENT FROM SOUTHEAST TO NORTHWEST OVER OUR AREA. STORMS SHOULD CONCENTRATE WEST OF THE RIO GRANDE AGAIN TONIGHT...WHERE ISOLD MTN TSRA/WND VRB20G35KT/CIGS 040- 060/LCL VIS 1-3SM ARE EXPECTED THROUGH 03Z. LOOK FOR SCATTERED LOWLAND TSRA/WND VRB30G45KT/CIGS 080-100/LCL VIS 1-3SM THRU 06Z OVER THIS AREA. ISOLATED MTN AND LOWLAND ACTIVITY IS EXPECTED GENERALLY EAST OF THE RIVER THROUGH 06Z. SKY OUTSIDE STORMS FEW-SCT060-100 SCT 140-180 LYRD SCT-BKN 300-350. && .FIRE WEATHER...HEALTHY PLUME OF MONSOON DRIVEN MOISTURE WILL CONTINUE TO FLOW NORTH-NORTHEAST OVER THE REGION. HOWEVER THE UPPER LEVEL HIGH WILL RECENTER WESTWARD OVER THE FOUR CORNERS OVER THE NEXT COUPLE OF DAYS. THIS WILL CAUSE THE SUB TROPICAL STREAM TO CORRESPONDINGLY SHIFT WEST OF OUR AREA BY MID WEEK...BRINGING DRIER AND HOTTER WEATHER BACK INTO THE PICTURE. REDUCED STORM CHANCES FOR ALL AREAS...WITH INCREASING MIXING HEIGHTS AND FREQUENCY OF CLOUD TO GROUND STRIKES...ARE THE SIGNIFICANT CHANGES WE CAN EXPECT AS A RESULT. LOOK FOR LOWLAND MAX TEMPS UN THE UPPER 90S AND MOUNTAIN HIGHS TO THE MIDDLE 70S FOR MOST OF THIS WEEK. MIN RH TUESDAY WILL DROP AS MUCH AS 10 PERCENT IN THE BOOTHEEL, FROM TODAYS READINGS THERE. UP TO A 5% DROP IS EXPECTED FOR AREAS EAST OF THE RIO GRANDE TUESDAY. READINGS WILL REACH THE MIDDLE TEENS WEDNESDAY IN A FEW LOWLAND SPOTS. && .PRELIMINARY POINT TEMPS/POPS...
