.AVIATION...
A SHORTWAVE TROUGH MOVING ALONG THE NORTHWESTERLY FLOW ALOFT WILL
HELP GENERATE SHOWERS AND THUNDERSTORMS ACROSS SE TX THIS
AFTERNOON. THE 17Z SURACE SHOWED A WEAK BOUNDARY FROM NEAR KCLL TO
KIAH TO THE COAST. RADAR ALSO SHOWED SHOWERS AND THUNDERSTORMS
DEVELOPING ALONG THE BOUNDARY.

THE MODELS DIFFERED A BIT ON CONVECTION TODAY. HOWEVER...A
CONSENSUS IS FOR THE STORMS TO DISSIPATE BY AROUND 01Z. VFR IS
THEN EXPECTED THROUGH THE NIGHT...ALTHOUGH THERE IS AN OUTSIDE
CHANCE FOR MVFR OR IFR AT THE SITES OUTSIDE OF METRO HOUSTON.

THERE IS ALSO ANOTHER CHANCE FOR THUNDERSTORMS WEDNESDAY AFTERNOON
AT KIAH.

EASTERN FORECAST AREA SHOWERS WITH A NW GULF MCV (FROM OLD
CONVECTIVE OUTFLOW) GENERATING FAR SE`ERN MARINE ZONE
THUNDERSTORMS. NEAR 90F CONVECTIVE TEMPERATURES WILL LIKELY BE
MET SHORTLY AFTER NOON SO EXPECTING MORE WIDESPREAD PRECIPITATION
DEVELOPMENT THIS AFTERNOON ..RANDOM IN COVERAGE. EARLY DAY CLOUD
COVER MAY END UP KEEPING MANY SITES IN THE LOWER TO MIDDLE
90S...VERSUS YESTERDAY WHERE MANY TOPPED OUT IN THE UPPER 90S. THE
