Area forecast discussion, Jul 12, 5:47 PM CDT, 3 hours 57 minutes before
Area Forecast Discussion National Weather Service Amarillo TX 547 PM CDT TUE JUL 12 2016 .AVIATION... 00Z TAF Cycle A frontal boundary across the eastern Panhandles and surface trough across the western Panhandles along with surface heating and low level moisture will allow for the possibility of isolated convection this evening. The Amarillo TAF site has the most likely chance for convection and included a TEMPO group from 00Z to 04Z Wednesday. Low confidence at the Dalhart and Guymon TAF sites and left out for now. VFR conditions expected through 00Z Thursday. East and southeast winds will veer around to the south and southwest 5 to 15 knots with some 15 to 25 knots at the Amarillo TAF site after 02Z to 04Z Wednesday with some higher gusts possible. Winds should veer more to the west and northwest after 14Z to 16Z Wednesday after the surface trough move east across the TAF sites. Schneider && .PREV DISCUSSION... /Issued 330 PM CDT TUE JUL 12 2016/ DISCUSSION... Isolated showers and thunderstorms will be possible through this evening along a front which has stalled across the eastern Texas Panhandle. More showers and thunderstorms may be possible across the northern CWA as convection forms over southeast Colorado and northeast New Mexico and heads this way in the westerly flow aloft. A surface trough will set up across the eastern CWA and the southwest winds behind it should help temperatures warm back up into the 98 to 108 range again. This surface trough should be another focus for shower and thunderstorm development Wednesday afternoon and Wednesday night. Shower and thunderstorm chances go up Thursday through Friday night as a cold front moves into the area and then stalls. The weather then starts to dry out for the rest of the forecast as an upper level ridge builds over the region. && .AMA Watches/Warnings/Advisories... TX...None. OK...None. && 11/10
