.UPDATE...
EVENING FORECAST UPDATE.

.DISCUSSION...
OVERALL SHOWER/THUNDERSTORM ACTIVITY HAS WEAKENED AS IT PUSHED
INLAND TODAY. THERE ARE STILL SOME SHOWERS OVER THE BRAZOS VALLEY
THAT SHOULD BE DISSIPATING OVER THE NEXT HOUR OR TWO. SHOWERS AND
THUNDERSTORMS REMAIN IN THE UPPER TX COASTAL WATERS BUT ARE NOT
MAKING ANY PROGRESS TOWARDS THE COAST. TWEAKED POPS TO MATCH
LATEST OBS AND FORECAST TRENDS. WITH TROPICAL AIRMASS IN PLACE
OVER THE AREA...EXPECT ANOTHER ROUND OF SHOWERS/THUNDERSTORMS
TOMORROW AND THUR. LOCALLY HEAVY RAINFALL WILL BE THE MAIN THREAT
AS RAIN RATES COULD REACH 2 INCHES AN HOUR. THOSE KINDS OF RAIN
RATES WERE OBSERVED TODAY OVER HARRIS COUNTY WHERE FLOOD
ADVISORIES WERE ISSUED FOR STREET FLOODING. TEMPS WERE ALSO
ADJUSTED SOME FOR CLOUD COVER AND RAIN CHANCES. LOOKS LIKE
RESPECTABLE RAIN CHANCES WILL CONTINUE INTO THE WEEKEND WHICH
SHOULD KEEP MAX TEMPS IN THE 80S/LOW 90S.
