Aviation... 
no major changes to previous taf reasoning. Aside from a few 
patches of fog around sunrise at the usual locations (cxo and 
lbx) expect VFR conditions to prevail next 24 hours. 38

Previous discussion... /issued 936 PM CDT Wednesday Jun 19 2013/ 


Update... 
evening forecast update. 


Discussion... 
final thunderstorm activity has come to an end over northwest Harris 
County. Storms today did dump heavy rainfall for an hour or two 
with pulse behaviors. Houston iah picked up nearly an inch of 
rain in an hour this evening. Some other hcfcd gauges showed 1-2 
inch amounts in isolated areas. Nearly 1.5 inches was reported 
near Johnson space center. Main change to the forecast was to 
remove probability of precipitation for the rest of the night. Otherwise the forecast 
looks on track with maximum temperatures in the middle 90s and slight 
thunderstorm chances due to higher moisture levels with lift from 
the sea breeze each afternoon. Convective chances look to fight 
subsidence from upper level ridging so possible that rain chances 
will be less than 20 percent in some cases. Updated forecast will 
be issued shortly.

see aviation for 00z taf discussion 


Aviation... 
isolated convection continues across the region this evening thus 
will keep thunderstorms in the vicinity mention in for a few sites over the first hour or 
so of the taf period. Only concern this evening is mesoscale convective system just to the 
south of the dfw metroplex that continues to move southeastward. 
If this were to hold together it could impact uts and cll by as 
early as 0130-0200z but am not convinced it will persist that 
long. Have left any mention of it out of the tafs for now but may 
have to amend as it approaches. Otherwise expecting VFR conditions 
to prevail for most sites through the forecast with drier 
conditions expected tomorrow afternoon. 38
