SHRA/TSRA CONTINUE IN AND AROUND MOST OF THE SE TX TAF SITES. HEAVIEST IMPACTED SITES CURRENTLY ARE SGR AND HOU. WITH ACTIVITY GRADUALLY SAGGING SOUTHWARD...LBX AND GLS SHOULD BE IMPACTED SOON. SHRA/TSRA ARE STILL POSSIBLE AT UTS AND CXO WITH THE LEAST IMPACTED LOCATION PROBABLY CLL. NOT REALLY SURE WHAT IS GOING TO HAPPEN LATER THIS AFTERNOON AND TONIGHT SINCE A LOT WILL DEPEND ON HOW LONG THE CURRENT ACTIVITY LASTS. GENERALLY EXPECTING MVFR CEILINGS AND VISIBILITIES WITH IFR/LIFR CONDITIONS LIKELY IN AND AROUND THE STRONGER STORMS. 42 && .PREV DISCUSSION... /ISSUED 356 AM CDT MON APR 18 2016/ DISCUSSION... SEVERE...HISTORIC FLOOD EVENT ONGOING. SEVERAL FLASH FLOOD WARNINGS AND FLASH FLOOD EMERGENCIES IN EFFECT FROM SLOW MOVING BAND OF THUNDERSTORMS. MULTIPLE HIGH WATER RESCUES REPORTED AND STRUCTURES BEING FLOODED. UNFORTUNATELY BAND OF THUNDERSTORMS TO IMPACT AREAS ALREADY HAVING RECEIVED HEAVY RAIN FOR POTENTIALLY SEVERAL MORE HOURS. WORST CASE SCENARIO AS DEEP MOISTURE ADVECTING IN OFF THE GULF AND BEING FOCUSED ALONG E TO W BAND OF THUNDERSTORMS WITH VERY LITTLE MOVEMENT. MODELS HAVE STRUGGLED TO CAPTURE PLACEMENT AND TIMING OF CONVECTION AND DIFFICULT GOING FORWARD AS WELL. NOT MUCH CHANGE IN THE PATTERN IS EXPECTED THROUGH TUESDAY. THROUGH TUESDAY EXPECT ADDITIONAL ROUNDS OF HEAVY RAIN WHICH WILL ONLY EXACERBATE FLOODING ALREADY ONGOING. DIFFICULT TO TIME THINGS BUT THUNDERSTORM COMPLEXES WILL GENERALLY BE SLOW MOVING. CONCERN IS THEY WILL OCCUR IN SIMILAR AREAS. HAVE HAD TO RAISE POPS WEDNESDAY AS WELL AS MODELS SHOWING ANOTHER VORT LOBE PIVOTING AROUND UPPER LOW LIKELY BRINGING MORE SHOWERS AND THUNDERSTORMS. REALLY DONT DRY OUT UNTIL POSSIBLY FRIDAY AS MODELS SUGGEST RIDGING AT SURFACE AND ALOFT. 46 MARINE...
