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.
