Area forecast discussion, Jun 15, 3:14 PM CDT, 1 hour 47 minutes before

Area Forecast Discussion
National Weather Service Birmingham AL
314 PM CDT Thu Jun 15 2017

.SHORT TERM...
Through Tonight.

An active outflow boundary has pushed into north Alabama this
afternoon. Very unstable air ahead of the boundary has triggered
strong to severe thunderstorms along the leading edge of the
boundary. This outflow boundary will continue to track southeast
with widespread showers and thunderstorms through the early
evening hours. A large area of light to moderate rain extends well
north of the main convective line, so rain will continue well
into the evening across north central Alabama. Expect most of the
rain will dissipate by midnight.

58/rose

.LONG TERM...
Friday through Wednesday.

A weak 500 mb trough is expected to persist across much of the
Southeast CONUS through the weekend. This pattern will favor
scattered to perhaps numerous showers and storms each day mainly
driven by daytime heating. A front should approach from the north
on Monday as a strong upper trough takes shape over Southeast
Canada and the Great Lakes. The front is expected to lose its
upper-level support and move slowly across the forecast area,
serving as a focus for convection on Monday and Tuesday. Rain
chances across our northern areas may decrease for Tuesday into
Wednesday as drier air and weak high pressure moves into the
Tennessee Valley behind the front.

87/Grantham

&&

.AVIATION...
18Z TAF Discussion.

A very moist and unstable air mass will result in sct-nmrs showers
and tstms across central Alabama this afternoon and early
evening. The most organized activity will be along and north of
I-20. An outflow boundary currently across northeast Mississippi
will track southeast and into northwest Alabama early this
afternoon, likely reaching the I-20 corridor by 20-21z. The storms
will produce frequent lightning, vsbys blo 3 miles, and wind
gusts of 30-40 mph. South of I-20, the activity will be less
organized, but still capable of producing the same hazards as
listed above. The convective activity should weaken and mostly
dissipate by 01z. Low clouds and fog could impact KMGM and KTOI
between 10z and 14z.

58/rose

&&

.FIRE WEATHER...

Scattered showers and storms are expected through the next
several days with a moist airmass in place. The best chance of
rain will occur during the afternoon and early evening hours.
There are no fire weather concerns.
