SEEING AREAS OF DZ/-RA ACROSS THE AREA. THESE HAVE BEEN INCREASING
THIS EVENING. VERY FAVORABLE ISENTROPIC LIFT SETUP FOR INLAND AREAS
INTO SUN AM. HAVE BUMPED POPS UP TO ACCOUNT FOR THE ONGOING
PRECIP TRENDS. MADE A FEW ADJUSTMENTS TO OVERNIGHT TEMPS. WILL SEE
A VERY SLOW RISE LATE TONIGHT. SOME FOG IS POSSIBLE AROUND
MATAGORDA BAY...BUT ELSEWHERE DO NOT EXPECT MUCH FOG...AT LEAST
SIGNIFICANT FOG. MAY SEE SEA FOG BEGIN LATE SUN AFTERNOON ALONG
THE COAST. 33

SEE 00Z AVIATION DISCUSSION.

AVIATION...
MISERABLE FLYING CONDITIONS ARE EXPECTED FOR THE NEXT 24-36 HOURS.
A WARM FRONT DEVELOPING OVER THE WESTERN GULF WILL SERVE AS A
FOCUS FOR FOR LIFR CIGS AND RESTRICTED VISIBILITY. MVFR CIGS WILL
QUICKLY FALL TO LIFT/VLIFR OVERNIGHT WITH PERIODS OF VERY LIGHT
RAIN AND DRIZZLE. MOISTURE DEEPENS TOWARD MORNING WITH PW VALUES
INCREASING TO 1.40 INCHES BY 12Z. INSTABILITY ALSO INCREASES
SUNDAY MORNING AND THE PRECIPITATION COULD BECOME MORE CONVECTIVE
IN NATURE. DID NOT INCLUDE THUNDER IN THE TAFS BUT HAVE SOME MINOR
CONCERNS REGARDING CONVECTION BETWEEN 15-21Z. A STRONG TEMPERATURE
INVERSION WILL LIKELY LIMIT MIXING AND KEEP LOW CIGS IN PLACE
THROUGH MONDAY. SEA FOG WILL ALSO DEVELOP SUNDAY NIGHT AND WILL
LIKELY IMPACT THE KGLS TAF WITH LOW CIGS/VSBYS. 43
