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 Jul 31, 3:57 PM CDT, 58 minutes earlier.

Area forecast discussion, Jul 31, 3:57 PM CDT, 58 minutes before

Area Forecast Discussion
National Weather Service Mobile AL
357 PM CDT SUN JUL 31 2016

.NEAR TERM /Now Through Monday/...Convection will taper off this
evening as instability decreases across the area. The absent of
vertical shear and elevated Wet Bulb Zero (WBZ) heights will limit
the potential for severe storms. Although high precipitable water
amounts and MU capes of 2000 to 3500 J/Kg will create for some
explosive updrafts and heavy water loading potentially leading to
some gusts in the 40 mph range...so and cannot completely rule out
isolated severe gusts. Showers and thunderstorms will decrease in
coverage and intensity as we move into the evening hours with all
activity ending by midnight and then forming over the Gulf.

Little change expected in the diurnally driven convective cycle
tomorrow except more convection is expected over our Southeast MS
counties where convection was hindered today by the limited low
level instability...that won't be the case Monday. Overnight lows in
the 70s and near 80 along the coast and daytime highs in the low to
mid 90s are anticipated. /08

.SHORT TERM /Monday night Through Wednesday night/...A moist humid
pattern continues with precipitable water amounts hovering around 2
inches..deep layer ridging over the area with shortwave energy
occasionally rippling through it. All of this results in a
continuation of the current weather pattern with diurnally driven
convective activity...muggy mornings and hot and humid afternoons.
Overnight lows in the upper 70s to near 80 along the coast and mid
70s inland. Daytime highs will climb into the low to mid 90s with
heat indices reaching the low to mid 100s. /08

.LONG TERM /Thursday Through Sunday/...Model guidance continues to
project deep layer ridging over the region and ample moisture pooling
to keep precipitable water amounts in the 2 inch arena. Little change
expected in sensible weather with the diurnal convective pattern
continuing through Sunday. Temperatures will trend near to above
climatological norms.

Note: We continue to monitor the evolution of the fast moving tropical
disturbance over the Eastern Caribbean Sea this afternoon. Current
guidance from the National Hurricane Center as well as global
forecast models keep any  possible development with this system well
to the southwest of us...Southern Mexico...Yucatan Peninsula area so
little impact expected at this time. But things could change as the
system evolves...please refer to the National Hurricane Center for
the latest updates. /08

&&

.MARINE...High pressure continues across the North Central Gulf
through the week. Generally a light south to southwest wind flow is
expected to prevail through early next week. Winds and seas will be
higher in and around isolated to scattered showers and thunderstorms
through the forecast period. /08
