Area Forecast Discussion
933 FXUS64 KHUN 301932 AFDHUN Area Forecast Discussion National Weather Service Huntsville AL 232 PM CDT SAT JUL 30 2016 .DISCUSSION... One upper disturbance in now moving across the TN valley and another one is now over nw AR. The current batch of shra/tsra were moving east arnd 30 mph and should be out of the cwa before 00z. We did get some reports of a few trees down and a house fire caused by lightning. Thinking that much of the early evening hours will be pcpn free. However the previously mentioned disturbance over nw AR may produce some isolated shra/tsra later tonight across the cwa. Thus will keep a low pop just in case. On Sunday the area will still be affected by an upper trof and once again more sct shra/tsra will be possible. The upper trof will begin to lift back north on Monday as an upper ridge begins to build eastward from the wrn US. Will maintain chc pops for both Sunday and Monday mainly for aftn and evening shra/tsra. For Tuesday thru Thursday the ridge will be over much of the sern US which will allow temps to rise into the mid 90s. These temps along with dewpoints in the lower 70s will produce another round of heat indices between 100 and 105 degrees. Pcpn chances will be on the low side but not zero. For Friday and Saturday the TN valley will transition to more of a nw flow pattern. This will increase the chc of pcpn a little and perhaps bring a little cooler temps as well. Overall expect this summer wx pattern to continue thru this fcst package, with mainly aftn/evening shra and tsra. The svr wx threat will be low but any tsra will be capable of producing gusty winds and heavy rain. Otherwise aftn highs will be in the 90s with mrng lows arnd 70. 007 && .AVIATION...
