The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

Area forecast discussion, May 16, 3:15 PM CDT, 3 hours 21 minutes before

Area Forecast Discussion
National Weather Service Birmingham AL
315 PM CDT Thu May 16 2019

.SHORT TERM...
Through Tonight.

Isolated storms have developed across the northeast counties of
central Alabama along the back side of an upper trof over the
eastern United States. With plenty of dry aloft for evaporative
cooling, expect some of the storms to contain wind gusts 40-45
mph and small hail. Stronger ridge over west Alabama should keep
activity for areas mainly east of I-65. The activity will linger
into the evening hours, and continued isolated storms.

58/rose

.LONG TERM...
/Issued at 330 AM CT/

Friday through Wednesday.

The upper level disturbance will slowly exit the region
Friday. With this in place and another warm day expected, look
for at least isolated showers or afternoon thunderstorm in the
east. Highs will be in the upper 80s with lows in the mid 60s.

Surface high pressure continues eastward on Saturday increasing
southerly flow and moisture back into the region. An upper level
trough slides through the Central Plains as a surface low lifts
northeastward Saturday through Sunday. A southward extending cold
front associated with the surface low will begin to move towards the
area on Sunday increasing rain chances. There still remains some
uncertainty regarding coverage Sunday through Monday. However, the
best chances look to be in our northern and western counties so I
have increased PoPs in these areas. Have kept the chance for
thunderstorms during this time frame given daytime instability and
frontal lifting.

This boundary will lift northeast Monday night/Tuesday, clipping our
far northern counties. Upper level riding begins to become more
amplified across the southeastern US as another upper level trough
and surface low dig through the Plains. Therefore, minimal rain
chances are expected through at least the middle of next week.
Temperatures in the extended look to be slightly above average with
most area reaching the upper 80's during the day.

07

&&

.AVIATION...
18Z TAF Discussion.

VFR conditions will continue through this forecast period with
high pressure and subsidence limiting organized thunderstorm
activity this afternoon. A cumulus deck has begun developing
across the area and daytime heating should be sufficient to
develop a couple isolated thunderstorms this afternoon, but the
lack of an organized lifting mechanism and region wide sinking
motion should limit widespread activity. Left thunder out for now
but will amend if necessary.

86

&&

.FIRE WEATHER...

A slow moving upper level disturbance will help provide isolated
to scattered showers/storms to the area today and tomorrow. Min RH
values will be in the 40 to 50 percent range. Dry weather returns
Saturday, with a front approaching the area on Sunday
night/Monday. There are no fire weather concerns at this time.
