...HEAVY RAINFALL POSSIBLE ACROSS THE SOUTH PLAINS AND SOUTHERN TEXAS PANHANDLE SATURDAY THROUGH TUESDAY... THE COMBINATION OF A STRONG UPPER LEVEL STORM SYSTEM OVER THE WESTERN UNITED STATES AND TROPICAL MOISTURE ASSOCIATED WITH A DECAYING EASTERN PACIFIC HURRICANE WILL RESULT IN PERIODS OF HEAVY RAINFALL FOR THE AREA THROUGH THE WEEKEND. IN ADDITION...A COLD FRONT IS EXPECTED TO MOVE SOUTH ACROSS THE REGION MONDAY BRINGING AN ADDITIONAL FOCUS FOR HEAVY RAINFALL INTO EARLY NEXT WEEK. ALTHOUGH IT IS TOO EARLY TO PINPOINT EXACTLY WHERE THE HEAVIEST RAINFALL MAY OCCUR...WIDESPREAD RAINFALL AMOUNTS OF 1 TO 3 INCHES WILL BE POSSIBLE ACROSS MOST OF THE SOUTH PLAINS AND SOUTHERN PANHANDLE BY LATE TUESDAY. SOME LOCATIONS COULD EASILY SEE RAIN TOTALS IN EXCESS OF 4 INCHES GIVEN THE PROLONGED NATURE OF THIS EVENT. LOCATIONS OFF THE CAPROCK ARE EXPECTED TO GENERALLY SEE LESSER AMOUNTS BUT THIS COULD CHANGE IF THE SYSTEM WERE TO SPEED UP OR THE AXIS OF MOISTURE SHIFT EAST. ALTHOUGH WIDESPREAD FLOODING IS NOT EXPECTED AT THIS TIME THE LIKELIHOOD OF EXCESSIVE RUNOFF WILL INCREASE AS THUNDERSTORMS REDEVELOP AND MOVE OVER THE SAME AREA. AS FORECASTS BECOME MORE CLEAR AS TO WHERE AND WHEN THIS MAY HAPPEN...A FLOOD WATCH WILL BE CONSIDERED. LISTEN TO NOAA WEATHER RADIO OR YOUR LOCAL MEDIA FOR THE LATEST UPDATES ON THIS DEVELOPING SITUATION.
