Discussion... 
please see 06z aviation discussion... 


&& 


Aviation... 
several late afternoon thunderstorms were triggered by the 
collision of the sea breeze with remnants of a frontal boundary 
across the southern portions of the Houston metropolitan area. These 
storms provided some additional surface moisture that may improve 
chances for MVFR conditions and khou and ksgr. At this time...I 
left VFR conditions in the khou taf. However...I would not be too 
surprised to see patchy MVFR ceilings there before sunrise. MVFR 
ceilings/visibility are expected at klbx, kcxo, and kcll. 


VFR conditions will return to all terminals by mid-morning. 
Widely scattered showers are possible at the coastal terminals in 
the morning and thunderstorms are possible at Houston metropolitan 
terminals in the late afternoon. I do not anticipate any 
significant precipitation to the north of kiah. 


Prevailing winds should be variable at 5 knots or less through the 
forecast period. 44
