The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Birmingham, AL wrote its last area forecast discussion before this special weather statement went out at Jun 23, 4:01 PM CDT, 38 minutes earlier.
Area forecast discussion, Jun 23, 4:01 PM CDT, 38 minutes before
Area Forecast Discussion National Weather Service Birmingham AL 401 PM CDT Fri Jun 23 2017 .DISCUSSION... Through Tonight. The final convective band associated with tropical depression Cindy has pushed to the I-59 corridor this afternoon. The air mass is moderately unstable with decent shear and helicity east of the band to promote a few rotating storms. Because surface winds have veered more to a southwest direction, the wind flow has become more unidirectional and lessened the low level directional shear. This has lessened the tornado threat as the the convective mode becomes more linear. Heavy rainfall and flash flooding is still a big concern with this activity. The convective band should exit east Alabama by 6 pm and any remaining counties still under a tornado watch will likely be cleared. The heavier rainfall should also be east of the current flash flood watch and it will be allowed to expire at 7 pm. Even though there is an upstream MCS over northern Arkansas, this system will likely stay west of Alabama as it tracks towards the Mississippi river. As the remnants of Cindy pulls off to the northeast towards the mid- Atlantic states, a cold front will get pulled southward tonight and into extreme north Alabama by sunrise Saturday. The presence of the cold front will keep scattered showers and a few thunderstorms across north Alabama overnight. 58/rose && .AVIATION... 18Z TAF Discussion. Primary Impacts: A line of shwrs/tstms will spread eastward across north central Alabama thru 00z. Gradient winds ahead of the convective line will be from the SSW at 12-18 knots with gusts to 25 knots, but could gust to 40-50 knots along the leading edge of the line. Cigs outside the convective line should stay above 3000 feet agl. Vsbys will likely lower to less than 1 mile in any showers or thunderstorms due to the tropical nature of the air mass. Little if any aviation concerns at KMGM and KTOI thru 23z, but southern end of the convective line should be reach these airports after 23z. The air mass will stabilize after 01z and tstm activity will diminish greatly as the convective line pushes into Georgia. VCSH expected overnight as a surface front approaches from the northwest. IFR cigs will also likely form after 09z area wide due to weak convergence ahead of the sfc front and very moist conditons. 58/rose && .FIRE WEATHER... High rain chances will continue through Saturday with rain chances decreasing for Sunday and Monday behind a cold front. There are no fire weather concerns. && .PRELIMINARY POINT TEMPS/POPS...
