THE BIG CONCERN THIS FORECAST PERIOD IS ANOTHER FLASH FLOOD SCENARIO SETTING UP. THE UPPER LOW IS PROGGED TO DRIFT SOUTHWEST BACK ACROSS THE HILL COUNTRY AND SOUTH CENTRAL TEXAS TUESDAY AND WEDNESDAY. WITH A TROPICAL AIRMASS IN PLACE, THE LOW WILL PRODUCE PERSISTENT RAINS TUESDAY NIGHT THROUGH WEDNESDAY MORNING. RAINFALL AMOUNTS AROUND THE UPPER LOW COULD EASILY REACH 4 INCHES TUESDAY NIGHT. CURRENT THINKING IS THIS AMOUNTS IS PROBABLY WEST OF A LINE FROM AUSTIN TO SAN ANTONIO, BUT COULD CHANGE AS SUBSEQUENT MODEL RUNS WILL BETTER PINPOINT THE FINAL TRACK OF THE UPPER LOW. UNTIL THIS HAPPENS, AND EVEN AFTER IT HAPPENS, A MID AND UPPER LEVEL TROF AXIS WILL RESIDE OVER SOUTH CENTRAL TEXAS THROUGH FRIDAY. THE AXIS STARTS OUT ORIENTED NORTHEAST-SOUTHWEST, SLICING THE HILL COUNTRY AND SOUTH CENTRAL TEXAS IN HALF. THEN AS THE LOW CENTER SLIDES SOUTHWEST OUT OF OKLAHOMA TO THE RIO GRANDE, THE UPPER HIGH NOSES EAST ACROSS THE CENTRAL U.S., CAUSING THE TROF AXIS TO BECOME EAST-WEST ORIENTED BY FRIDAY. DAY TO DAY RAIN COVERAGE WILL BE GREATER EAST AND SOUTH OF THIS AXIS. MAX TEMPERATURES WILL BE RAIN AND SOIL MOISTURE DEPENDENT THROUGH FRIDAY. AFTERWARD, THE AFTERNOON SHOWERS WILL BE MORE ISOLATED, ALLOWING TEMPS TO RISE BACK TO SEASONAL NORMALS AS THE SOIL SLOWLY LOSES MOISTURE. && .PRELIMINARY POINT TEMPS/POPS...
