Area forecast discussion, Jul 8, 6:30 PM CDT, 2 hours 23 minutes before
Area Forecast Discussion National Weather Service Houston/Galveston TX 630 PM CDT Sat Jul 8 2017 .AVIATION... Scattered, outflow dominated shra/tstms around the metro area should dissipate in the next couple hours with the loss of heating. Further n/ne toward the UTS/CXO terminals we're watching a slightly more organized cluster of storms sagging into the area. These too should diminish, but may persist and impact those terminals through 2-3Z or so. Localized heavy rain and wind gusts to 40kt possible in the strongest cells. After 3z or so, expect VFR conditions to persist areawide. As with previous days, iso/sct precip development offshore before sunrise, transitioning inland late morning & afternoon. Boundary that is presently generating the east Tx storms moves a bit closer on Sunday, so would anticipate generally more coverage than we saw today - especially east of a CLL-GLS line. 47 && .PRELIMINARY POINT TEMPS/POPS...
