ISOLATED TO SCATTERED SHOWERS WILL CONTINUE TO DEVELOP AND STREAM NORTHEASTWARD ACROSS THE REGION. GENERALLY EXPECT THIS ACTIVITY TO CONTINUE OVERNIGHT...BUT WILL BE VERY LIMITED IN AREAL COVERAGE. ANOTHER WARM DAY IS ON TAP FOR MONDAY AS WARM SOUTHERLY FLOW INCREASES AHEAD OF THE APPROACHING COLD FRONT. COULD SEE SOME PATCHY FOG TOMORROW MORNING AS MOISTURE ADVECTION WILL BE SUFFICIENT...BUT ANY FOG WHICH DEVELOPS SHOULD NOT BE MUCH OF AN IMPACT SO HAVE LEFT IT OUT OF THE GRIDS. WITH THE MOIST SOUTHERLY FLOW COULD SEE SOME MAINLY AFTERNOON SHOWERS AND THUNDERSTORMS ACROSS THE EASTERN HALF OF THE CWA...BUT AGAIN WILL BE ISOLATED IN NATURE. RAIN CHANCES WILL BEGIN TO INCREASE AREA-WIDE MONDAY NIGHT AND PEAK ON TUESDAY AS THE FROPA PUSHES TOWARD THE COAST. PRECIPITABLE WATER VALUES WILL BE CLOSE TO OR ABOVE 2 INCHES ACROSS SOUTH CENTRAL TEXAS ON TUESDAY. HEAVY RAINFALL WITH ISOLATED TOTALS OF 2 TO 4 INCHES (POSSIBLY HIGHER IF THE FRONTAL BOUNDARY STALLS AND ALLOWS REDEVELOPMENT OF STORMS) CAN THUS BE EXPECTED TUESDAY AND INTO WEDNESDAY.

THE FRONT IS EXPECTED TO GET HUNG UP ALONG THE COAST MID-WEEK AS THE UPPER LOW REMAINS ALMOST STATIONARY ACROSS THE GREAT PLAINS. THIS WILL LEAD TO RENEWED CHANCES FOR SHOWERS AND THUNDERSTORMS THROUGH THURSDAY AFTERNOON. THE BEST CHANCES FOR RAIN WILL BE PREDOMINANTLY ACROSS THE SOUTHERN HALF OF THE CWA DUE TO THE BETTER TAP OF GULF MOISTURE AND PROXIMITY TO THE FRONTAL BOUNDARY. TEMPERATURES WEDNESDAY MORNING WILL BE NOTICEABLY COOLER WITH AFTERNOON HIGHS BEING KEPT TO THE LOWER 80S MAINLY BECAUSE OF LIMITED SUNSHINE AND AREAS OF RAIN AND WEAK CAA.
