Updated for the 18Z TAF issuance. 



VFR conditions will continue for the rest of today and tonight. A
few isolated showers have been developing over the southern half
of the CWA but with minimal impacts to the TAF sites. These
showers are expected to dissipate in the evening. Short periods 
of MVFR to IFR cigs are possible due to patchy fog developing 
during the early morning hours Thursday, most probable over
CLL/CXO/UTS. Light southerly winds are expected tonight,
increasing to around 10 KTS by Thursday morning. 


.PREV DISCUSSION... /ISSUED 1023 AM CDT Wed Jul 17 2019/ 

Made just a few slight adjustments to forecast grids. Satellite 
and radar showing a few showers moving in off the Gulf. Will 
likely see some isolated showers and possibly a few thunderstorms 
this afternoon over land as we heat up. Model soundings show a 
weak cap...if parcel were to break the cap well see thunder...for 
convection that stays below just showers. The zone of this 
isolated activity will progress farther inland as we go through 
the afternoon...typical summer time progression. Coverage no more 
than 15 percent...with most locations rain free. Will be hot as 
well. After freshening the temp and dewpt grids...still looks like
well peak out just blow heat advisory criteria...but still 
important for those outside to take precautions. Typically Houston
summer time heat and humidity.
