What forecasters said that day

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 Mobile, AL wrote its last area forecast discussion before this special weather statement went out at Sep 25, 2:17 PM CDT, 1 hour 29 minutes earlier.

Area forecast discussion, Sep 25, 2:17 PM CDT, 1 hour 29 minutes before
Area Forecast Discussion...UPDATED
National Weather Service Mobile AL
217 PM CDT SUN SEP 25 2016

.DISCUSSION...See updated information below.

&&

.UPDATE...Did a quick update to the current zone forecast to reflect
current radar trends which shows scattered showers and thunderstorms
covering most locations in the forecast area. Believe this pattern
will hold through this afternoon and possibly up until sunset due to
slightly better instability compared to yesterday combined with
moderate forcing still present in the mid levels due to a weak upper
low located over much of the florida panhandle stretching north over
lower parts of Al and Ga. Thunderstorms will continue to move south
southwest at 10 to 15 mph. With these conditions gusty straight line
winds...frequent lightning and short periods of very heavy rain can
be expected with most of the stronger storms. Similar to yesterday
some strong to marginal severe thunderstorms will also be possible.
Stay tuned to local media outlets or noaa weather radar if
threatening weather is approaching your area. 32/ee

&&

.AVIATION...
00Z issuance...VFR to MVFR cigs and visibilities through early this
evening then mostly VFR conditions through 26.18z. Could see a some
patchy MVFR fog near sunrise also Mon morning. Winds will be variable
at 5 knots early this afternoon gradually shifting south at 5 to 10
knots late this afternoon thru early this evening then becoming light
and variable late this evening through much of Mon morning. 32/ee

&&

.PREV DISCUSSION... /issued 637 AM CDT SUN SEP 25 2016/

DISCUSSION...Updated for latest aviation discussion below.

AVIATION...
12Z issuance...VFR conditions will prevail through the next 24 hours.
/13

PREV DISCUSSION... /issued 411 AM CDT SUN SEP 25 2016/

NEAR TERM /Now Through Sunday night/...A weak upper level low will
linger across the area today. The combination of the upper low and
better deep layer moisture levels will allow for a slightly better
chance of showers and thunderstorms, especially across eastern zones
under the upper low. A few storms became strong to briefly severe
Saturday afternoon and cannot rule that out again this afternoon. The
primary threat will be gusty winds and quarter size hail. Thickness
values are similar to those on Saturday when we broke records at
Mobile and Pensacola. Therefore, went above guidance values for high
temps today with mid 90s in most areas. Lows tonight will remain
above normal with lows in the upper 70s inland to mid 70s along the
coast. 13/JC

SHORT TERM /Monday Through Tuesday night/...Surface ridging and a
weak upper level low will remain over the area through early
Monday...continuing the above normal daytime temperatures and
diurnally forced isolated showers and thunderstorms. Monday night
into Tuesday...a shortwave propagating east across the Great Lakes
area will help push a cold front into the southeastern states and
through our forecast area. Given the the upper low overhead and
additional forcing from the advancing surface front...have continued
slight to chance POPs through Tuesday night. Daytime highs on Monday
continue in the lower 90s over interior sections and upper 80s at the
coast...but cool to a closer to normal mid and upper 80s Tuesday
with the front moving through. Monday night lows ranging from the mid
60s inland to lower 70s coastal...then behind the front Tuesday night
look for near normal lows ranging from the upper 50s well inland to
the upper 60s and near 70 at the coast. 12/DS

LONG TERM /Wednesday Through Saturday/...On Wednesday and Wednesday
night...cooler and drier surface high pressure will begin to build
into the region from the west in the wake of the front...while well
defined trof in the mid/upper levels maintains deep layer cool/cold
air advection over the region. Thursday through Saturday surface
ridge slides slowly east across the region while high pressure aloft
builds. Daytime high temps will be near normal...in the low to mid
80s each day through the long term period. Overnight lows will be
near or just below normal...ranging from the mid 50s over interior
locations to the mid and upper 60s near the coast. 12/DS

MARINE...High pressure will continue over the marine area through
early this week then build from the north by midweek as a cold front
moves south over the northern Gulf. Easterly winds and seas will
build late in the week as high pressure to the north shifts east to
the Mid Atlantic states. 13/JC
