Area forecast discussion National Weather Service Austin/San Antonio Texas 242 PM CDT Friday may 24 2013 Short term (tonight through Saturday night)... this afternoon the mesoscale convective vortex was centered over Real County drifting northward. An associated line of showers and thunderstorms extended from Burnet southward to New Braunfels and Campbellton. The line was moving slowly east while the individual cells were moving northward. This is leading to cell training resulting in localized flooding. The threat for locally heavy rainfall and flash flooding associated with the line of convection will continue through the rest of the afternoon as heating interacts with precipitable waters of 1.5 to 1.75 inches. Strong outflow winds of 30 to 40 miles per hour were also occurring in advance of the line. The slow moving line will continue to move eastward for the remainder of this afternoon. The areal coverage of convection will diminish overnight with the loss of daytime heating. Another round of showers and thunderstorms is possible on Saturday as another upper level impulse moves across south central Texas. Highs on Saturday will be close to seasonal normals. && Long term (sunday through friday)... the upper level ridge is expected to strengthen across south central Texas on Sunday bringing an end to our rain chances. The upper level ridge axis will shift eastward Tuesday and Wednesday with the approach of a western U.S. Upper level trough. Rain chances will be on the increase Wednesday and Thursday as the upper level trough moves eastward across the Central Plains. Temperatures Sunday through Monday will be at or slightly above normal. && Preliminary point temps/pops...
