NWS Houston/Galveston, TX wrote its last area forecast discussion before the first event at Jul 5, 11:27 AM CST, 1 hour 38 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 1227 PM CDT SAT JUL 5 2014 .AVIATION... EXPANDING CU FIELD AT 17Z STRETCHES FROM ROUGHLY GLS TO IAH TO CLOSE TO UTS. SOME SHRA/TSRA ARE DEVELOPING IN AND AROUND THE AREA OF DEEPEST MOISTURE NEAR THE COAST...AROUND THE GLS AND LBX AREAS. AN OUTFLOW BOUNDARY FROM OFFSHORE CONVECTION IS MOVING INLAND ALONG THE COAST NEAR THE GLS AREA. AS HEATING CONTINUES...THINK WE WILL SEE MORE DEVELOPMENT AS BOUNDARIES INTERACT WITH EACH OTHER. FOR NOW...WILL CARRY VCTS THIS AFTERNOON AT THE LBX AND HOU AND SGR SITES AND MONITOR HOW THINGS PROGRESS OVER THE NEXT COUPLE OF HOURS. EXPECT ACTIVITY TO EXPAND MORE WESTWARD THAN NORTHWARD...BUT WOULD NOT BE TOTALLY SURPRISED IF SOMETHING DOES DEVELOP LATER THIS AFTERNOON IN AND AROUND THE IAH AND POSSIBLY THE CXO SITES. 42 && .PREV DISCUSSION... /ISSUED 929 AM CDT SAT JUL 5 2014/ UPDATE... SEE DISCUSSION FOR MORNING UPDATE. DISCUSSION... DRIER AIR HAS TRIED TO WORK ITS WAY INTO OUR FAR NORTHEASTERN COUNTIES THIS MORNING WITH VERY MOIST PWAT AIR REMAINING ACROSS THE HOUSTON AREA. HIGH RES HRRR AND TEXAS TECH WRF BOTH SHOW COVERAGE INCREASING DURING THE DAY TODAY WITH BEST CHANCES TOWARDS OUR SOUTHWESTERN AREAS. AT 500 MB VERY WEAK RIDGING REMAINS OVERHEAD WHICH SUPPORTS THE HIGH RES MODELS IN DEVELOPING PRECIP THIS AFTERNOON. CURRENT 12Z SOUNDINGS ALSO REVEAL FAIRLY DEEP MOISTURE AT KCRP (PWAT 1.87"). FORECAST PACKAGE HAS THIS COVERED. NO UPDATE REQUIRED AT THIS TIME. 23 PREV DISCUSSION... /ISSUED 339 AM CDT SAT JUL 5 2014/ DISCUSSION... LATEST MODEL DATA SHOWS DRIER AIR MAKING ITS WAY INTO NE/N PARTS OF THE REGION AND GOES SOUNDER IMAGERY CONFIRMS. STILL HAVE RESPECTABLE MOISTURE LEVELS ACROSS SRN PARTS OF THE AREA AND WILL GEAR HIGHER POPS GENERALLY SOUTH OF I-10 AND WEST OF I-45 TODAY. SEVERAL OUTFLOWS SEEN OFF THE UPPER COAST AND DISTINCT LANDBREEZE IS SETTING UP CONVERGENT ZONE SO WE COULD SEE SOME SCT ACTIVITY DEVELOP IN THE NEXT FEW HOURS. OTHERWISE...WEAK ONSHORE FLOW WILL MAINLY PERSIST FOR THE NEXT WEEK WITH SFC HIGH PRES CENTERED OFF TO THE EAST. FURTHER ALOFT SE TX WILL REMAIN IN A SLIGHT WEAKNESS BETWEEN RIDGES. COMBINATION OF BOTH SHOULD PROVIDE SOMEWHAT NORMAL CONDITIONS ACROSS THE REGION WITH HIGHS IN THE LOW/MID 90S AND LOWS IN THE 70S. SEABREEZE WILL BE PRIMARY FOCUSING MECHANISM FOR ISO/SCT PRECIP EACH DAY WITH OVERALL COVERAGE DEPENDENT ON SLIGHT VARIATIONS ON AVAILABLE MOISTURE. 47 MARINE... NOT A LOT OF CHANGES WITH THIS FCST OF DIURNAL LANDBREEZE/SEABREEZE CIRCULATIONS THE REST OF THE WEEKEND AS THE SFC HIGH LINGERS ACROSS THE CENTRAL U.S.. AS THE HIGH EDGES EAST...WE SHOULD SEE SLOWLY IN- CREASING ONSHORE WINDS FOR THE START OF NEXT WEEK. THESE LIGHT/MOD- ERATE SELY WINDS EXPECTED TO PREVAIL THE REST OF NEXT WEEK. 41 AVIATION... AN ABUNDANCE OF OUTFLOW BOUNDARIES OVER THE NEARSHORE WATERS HELPING TO PRODUCE SOME SCT PCPN THIS MORNING. THE CURRENT TRAJECTORY OF THE ACTIVITY SHOULD KEEP THINGS QUIET FOR MOST OF OUR SITES THIS MORNING (EXCEPT MAYBE GLS). HOWEVER SOME OF THE SHORT-TERM PROGS ARE SHOWING AN ACTIVE SEABREEZE FOR THE SWRN PARTS OF THE REGION (WHERE MOISTURE AND INFLOW ARE A BIT MORE FAVORABLE). AS SUCH MAY HAVE TO RECONSIDER REINTRODUCING VCSH/VCTS FOR LBX/SGR THIS AFTN/EVE. OTHERWISE VFR FOR THE REST OF TODAY. 41 CLIMATE... RAINFALL HAS NOW BEEN RECORDED IN HOUSTON ON JULY 4TH IN 11 OF THE PAST 15 YEARS...AND 59 OF THE PAST 126.
