/ISSUED 348 PM CDT FRI SEP 25 2020/  
 
SHORT TERM (TONIGHT THROUGH SATURDAY NIGHT)...  
 
SHORT TERM PERIOD REMAINS GENERALLY QUIET ACROSS SOUTH TEXAS WITH  
VERY DRY AIR IN PLACE. A FEW SHOWERS AND STORMS ARE NOTED SOUTH OF  
THE CWA ASSOCIATED WITH SOME MID LEVEL ENERGY AND SLIGHTLY HIGHER  
PWAT, BUT EXPECT THESE TO REMAIN SOUTH. PWAT VALUES FOR OUR AREA  
ARE BELOW 1 INCH WHICH IS WELL BELOW NORMAL VALUES AND SHOULD  
REMAIN THERE THROUGH THE SHORT TERM. FOG WILL BE POSSIBLE FOR  
INLAND AREAS ONCE AGAIN TONIGHT AS SOME VERY LOW LEVEL MOISTURE  
RETURNS WITH ONSHORE FLOW AND COINCIDE WITH VERY LIGHT OVERNIGHT  
WINDS. TEMPS SHOULD BE FAIRLY COOL AGAIN TONIGHT INTO THE 60S IN  
THE NORTHEAST AND LOWER 70S ELSEWHERE. WILL INCREASE A FEW DEGREES  
FOR SATURDAY NIGHT WITH INCREASED MOISTURE. HIGH TEMPERATURES WILL  
BE SIMILAR TO TODAY, BUT A DEGREE OR TWO WARMER. HAVE ISSUED A  
COASTAL FLOOD ADVISORY FOR TONIGHT WITH WATER LEVELS EXPECTED TO  
BE RIGHT AROUND 2 FEET MSL ONCE AGAIN.  
 
LONG TERM (SUNDAY THROUGH FRIDAY)...  
 
THE EXTENDED PERIOD STARTS OUT DRY AND CALM WITH DRIER THAN NORMAL  
CONDITIONS. A MID-LEVEL LOW SITUATED ACROSS THE TX/LA BORDER WILL  
KICK OUT A SHORTWAVE SUNDAY, WHICH DUE TO THE LOW PWATS IS NOT GOING  
TO GIVE US ANYTHING PRECIP WISE. IN THE MEANTIME, A TROUGH MOVING  
ACROSS THE NORTHERN PLAINS SATURDAY WILL STRENGTHEN AS IT BEGINS TO  
LIFT TO THE NORTHEAST. THE EXTENT TO WHICH IT DIGS DOWN INTO TEXAS  
WILL IMPACT THE STRENGTH OF A PROMISING COLD FRONT. MODELS SHOW THE  
FRONT IMPACTING OUR AREA SOMETIME ON MONDAY BUT THE EXACT TIMING AND  
STRENGTH IS UNCERTAIN. HOPEFULLY, OVER THE NEXT FEW MODEL RUNS THEY  
WILL COME INTO BETTER AGREEMENT AS THIS LONG AWAITED FRONT WILL  
BRING SEASONABLY COOLER TEMPERATURES AND A SLIGHT CHANCE FOR  
SHOWERS. DEPENDING ON THE TIMING OF THE FRONT, HIGHS ON MONDAY COULD  
BE NEAR NORMAL OR QUITE A BIT COOLER. IN ANY CASE, OVERNIGHT LOWS  
FOR MONDAY INTO TUESDAY ARE LOOKING VERY NICE WITH INLAND LOCALES  
EXPECTED TO DIP DOWN INTO THE 50S. MUCH DRIER AIR IS GOING TO FILTER  
IN BEHIND THE FRONT AND THIS SHOULD HELP TO KEEP TEMPS ON THE NICER  
SIDE FOR THE REST OF THE PERIOD.  
 
MARINE...  
 
A WEAK TO MODERATE ONSHORE FLOW WILL PERSIST THROUGH THE WEEKEND  
WITH BRIEF SCEC CONDITIONS SUNDAY IN ADVANCE OF AN APPROACHING  
COLD FRONT. THE FRONT IS EXPECTED TO PUSH OFFSHORE SOMETIME ON  
MONDAY WITH A STRONG OFFSHORE FLOW DEVELOPING IN ITS WAKE. SCA  
CONDITIONS ARE EXPECTED MONDAY AFTERNOON THROUGH TUESDAY MORNING  
WITH GUSTS APPROACHING GALE FORCE. WINDS WILL WEAKEN THROUGHOUT  
THE DAY TUESDAY WITH A LIGHT OFFSHORE FLOW CONTINUING THROUGH MID  
WEEK BEFORE ONSHORE FLOW RETURNS BY LATE IN THE WORK WEEK.
