Area forecast discussion, Jul 19, 2:42 PM CDT, 2 hours 22 minutes before
Area Forecast Discussion National Weather Service Birmingham AL 242 PM CDT TUE JUL 19 2016 .DISCUSSION... Showers and a few thunderstorms will continue into the early evening hours and then dissipate. Lows tonight in the 70s. Hot the next few days as the 500mb ridge over the plains states continues to take control over much of the country. A few locations in the west could touch 100. Heat indices should stay in the 100 to 105 range as dewpoints mix out into the 60s during the afternoon. Rain chances tomorrow through Friday are low with maybe an isolated shower or storm the farther south and east you go away from the upper ridge. As the ridge weakens slightly by the weekend and into early next week, isolated to scattered convection will return during the afternoon hours and daytime highs will back down from the upper 90s to mid 90s. 88 && .AVIATION... 18Z TAF Discussion. Scattered TS developing this afternoon and slowly moving southward.
