Area forecast discussion, Jun 8, 6:39 PM CDT, 2 hours 59 minutes before
Area Forecast Discussion...UPDATED National Weather Service Amarillo TX 639 PM CDT Thu Jun 8 2017 .AVIATION... For the 00Z TAFs, isolated to perhaps scattered thunderstorms are expected this evening across parts of the OK and TX Panhandles. Storm movement will generally be to the southeast. Have omitted mention of tstms at all TAF sites due to low confidence in any one site being impacted and expected mainly sparse coverage. Thunderstorm potential is forecast to diminish late tonight. Some cumulus clouds should redevelop Friday afternoon. However, thunderstorm formation is not anticipated at this time at any of the terminal sites. Andrade && .PREV DISCUSSION... /Issued 424 PM CDT Thu Jun 8 2017/ DISCUSSION... Potential exists for severe thunderstorms this evening. Moderately unstable airmass remains in place, and shear will be increasing as mid-level jet streak arrives from the northwest and low-level jet develops, setting up across eastern sections. A few thunderstorms may continue past midnight in eastern sections. Dry weather will prevail beginning Saturday, as mid-level ridge sets up over West Texas. Dry southwest flow aloft resumes Sunday, with Gulf remaining closed through at least Monday. Models and ensembles in good agreement through Tuesday, featuring dry air overhead and lee trof helping to support higher than normal 850 mb temperatures. This leads us to maintain forecast of maximum temperatures above those offered by blend through Tuesday, with potential for Heat Advisory criteria being reached in Palo Duro Canyon. Model divergence increases Tuesday and beyond, although there is good support for a brief cold frontal intrusion Tuesday night into Wednesday. Have accepted blend's idea of precipitation resuming Tuesday across eastern sections, but have limited pops to only slight chance. Cockrell && .AMA Watches/Warnings/Advisories... TX...None. OK...None. &&
