Area forecast discussion, May 12, 4:02 AM CDT, 1 hour 46 minutes before
Area Forecast Discussion National Weather Service SAN ANGELO TX 402 AM CDT THU MAY 12 2016 .SHORT TERM... (Today and Tonight) ...Thunderstorms and Slow Moving Cold Front... A weak cold front will continue to move slowly south across West Central Texas today, and this boundary will serve as a focus for continued showers and thunderstorms. Although the threat of large hail and damaging winds will continue until around sunrise this morning, mainly along and north of our Interstate 20 corridor, another developing concern is high rainfall amounts and associated flash flooding. As the low-level jet, which is currently around 40 knots from the south, weakens over the next several hours, the severe thunderstorm and flash flood threats should also diminish. With this surface frontal boundary lingering over our counties for today, will continue chance PoPs. For tonight...the potential for continued showers and thunderstorms will shift into our southern counties, as this front slowly moves into that area. .LONG TERM... (Friday through Wednesday) ...Rain Potential Continues... The upper pattern will continue to support shower and thunderstorm development through this weekend and into the start of next week. Another cold front will push into West Central Texas this weekend, and that will further enhance the potential for showers and thunderstorms. Given current model timing, will continue with the best rain chances on Sunday. That's when this next cold front and upper support will be best aligned over our counties. && .PRELIMINARY POINT TEMPS/POPS...
