Area Forecast Discussion
National Weather Service Birmingham AL
1229 PM CDT Thu Jun 15 2017

.UPDATE...
For 18Z Aviation.

&&

.SHORT TERM...
Today and tonight.

The forecast for today is a little complicated as several factors
must come into alignment during the day in order for the coverage
and intensity of the activity to be realized across the board. So
let's get down into the specifics. First off it's is almost
Summer, so there will be plenty of cape this afternoon to tap into
if any storm can develop. Like yesterday's discussion the
downdraft cape is also substantial, so any downburst would have
the potential for strong winds. Looking at the microburst
potential across the area models indicate that there is a moderate
to even high chance at seeing microburst with isolated damaging
winds in the southern half and a low to moderate chance in the
north. That along with expected convection would be enough to
continue with the threat for severe thunderstorms this afternoon
across the area, but why do we see a slight risk across the north
and only a marginal in the south.

Looking at radar this morning there are some showers and storms
now working through KY and headed south/southeast to TN.
Synoptically we are in a northwest flow, so this boundary and or
complex if it gets going should move into the area by late
morning/early afternoon. This boundary combined with daytime
heating and any cold pool that has developed would be a potential
scenario for development of stronger activity in the north and
more scattered damaging winds. Also there is a trough right along
the I-20 corridor that could provide additional lift for any
storms. In fact a rouge shower has just developed on the southern
edge of the trough so that will also need to be monitor through
the day. Activity should dissipate by or just after midnight once
again. So overall confidence is high that we will see storms
during the day, but there are some limiting factors as well that
causes some uncertainties and will need to monitored through the
day.

16

.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.

&&

.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.

.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.
