COLD FRONT HAS PUSHED INTO THE GULF THIS MORNING WITH MUCH DRIER
AIR FILTERING INTO THE REGION. EXPECT DEWPOINT TEMPS TO DROP INTO
THE 40S WITH RH IN THE AFTERNOON NEAR 25-30 PERCENT. WINDS WILL BE
GUSTY TO AROUND 20KTS SO THERE WILL BE AN ELEVATED FIRE DANGER FOR
THE AREA MAINLY W AND SW OF HOUSTON. MAIN FORECAST UPDATE DID
ADJUST CLOUD COVER FOR ONGOING TRENDS AS WELL AS TEMPS. MAX TEMPS
MAY BE A DEGREE OR TWO COOLER ACROSS THE AREA THAN PREVIOUS
FORECAST GIVEN COLD ADVECTION AND GUSTY WINDS.
