783 FXUS64 KHUN 301533 AAB AFDHUN Area Forecast Discussion...UPDATED National Weather Service Huntsville AL 1033 AM CDT THU JUN 30 2016 .UPDATE...To Lower High Temperatures...raise gusts...and tweak dewpoints. && .DISCUSSION... A cool start to the day this morning, as lows were in the mid 50s to lower 60s. Even under clear skies this has only allowed temperatures to climb into the 73 to 78 degree range (about 5 degrees cooler than the past few weeks at this time) in most locations. Clear skies will continue through much of the day, the exception being in our southeast counties, where some partly cloudy conditions could develop this afternoon. Fairly strong cold air advection can be seen in 12Z sounding data from surrounding offices at 850 mb and 925 mb. This should temper insolation effects today, keeping highs much more comfortable in the 84 to 89 degree range. Warmest temperatures will be near and south of the Tennessee River. Fairly low dewpoints in the mid to upper 50s will drop relative humidity values below 40 percent this afternoon, so be careful if conducting any outdoor burning. Raised wind gusts to between 10 and 15 mph this afternoon, due to some mixing of around 20 kt winds around 850 mb. Otherwise, forecast looks good. KTW && .AVIATION... (Issued 553 AM CDT THU JUN 30 2016) For 12Z TAFs: A large area of high pressure over the region will keep vfr conditions at both KMSL and KHSV thru the fcst period. 007 && .HUN Watches/Warnings/Advisories...
