AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 314 PM CDT TUE JUN 30 2015 .DISCUSSION... RATHER ACTIVE SEABREEZE THIS AFTN GIVEN THE ADDITION OF OUTFLOWS AND SUCH FROM THE STORMS MOVING UP FROM THE LOWER TX COAST (MOST- LY) AND FROM NORTH TX (TO A LESSER DEGREE). ATTM STILL EXPECTING THIS ACTIVITY TO DISSIPATE THIS EVENING WITH THE LOSS OF DAYTIME HEATING. WE SHOULD SEE YET ANOTHER ROUND OF STORMS TOMORROW WITH THE SEABREEZE/HEATING...BUT WILL BE KEEPING AN EYE ON THE CONTIN- UED ACTIVITY OVER THE WRN GULF. AS PER SATELLITE AND RADAR LOOPS THERE IS STILL QUITE A BIT OF MOISTURE/ENERGY IN THAT REGION AND POSSIBLY A FEW WAVES COMING IN FROM THE NORTH AS WELL. MODELS TRYING TO DRY THINGS OUT ACROSS SE TX THURS/FRI AS THE UP- PER RIDGE IS PROGGED TO BRIEFLY EXTEND DOWN FROM THE NW AND PWAT NUMBERS LOWER A BIT. WHILE NOT VERY CONFIDENT WITH THIS PROPOSED SOLUTION WILL GOT AHEAD AND LEAN THAT WAY FOR NOW. OTHERWISE THE RETREAT OF THE UPPER RIDGE AND ANOTHER SURGE OF GULF MOISTURE ON SAT/SUN WILL HELP TO INCREASE POPS ONCE AGAIN. 41 && .MARINE...
