Area forecast discussion, Jun 28, 12:28 PM CDT, 2 hours 10 minutes before
Area Forecast Discussion National Weather Service Houston/Galveston TX 1228 PM CDT TUE JUN 28 2016 .AVIATION... SHRA/TSRA beginning to develop. Will carry VCTS at all TAF sites with a TEMPO from 18-22z. Have added a wind gust group at all TAF sites as well since fcst soundings show an inverted V signature. Fcst soundings continue to advertise PW values in excess of 2.00 inches so vsby may fall below 3 miles in some spots in heavy rain. Precip should end around 02z with additional SHRA possible near the coast toward sunrise. Generally VFR conds expected outside of areas with convection. 43 && .PREV DISCUSSION... /ISSUED / DISCUSSION... GPS-Met data and aircraft soundings indicate atmos over SE Tx more similar to 12Z soundings from LCH which indicate 2-2.2" PWs. Sky remains mclear at 10am...but do anticipate a fairly rapid increase in clouds & storms by early afternoon once readings make it to 89-93F. Atmos should become quite unstable and the possibility of some strong storms exists with winds being the primary threat. Fcst soundings show a fairly distinct inverted-v profile by 21z/4pm. Morning analysis shows diffulent upper flow & will need to keep an eye on eventual position of seabreeze/baybreeze where storm mergers may enhance overall strength and rainfall amounts. Update consisted to mainly minor tweaks to grids to match current obs...the rest is about the same, but did include some iso svr & heavy rain wording for the more susceptible spots. 47 && .PRELIMINARY POINT TEMPS/POPS...
