National Weather Service Mobile AL
1228 PM CDT WED AUG 10 2016
.DISCUSSION...Updated for latest aviation discussion below.
&&

&&
.PREV DISCUSSION... /issued 1131 AM CDT WED AUG 10 2016/
DISCUSSION...See updated information for land areas below.
UPDATE...We have updated the forecast to increase the rip current
risk to high for today based on slightly higher than expected winds
and a check of local beach flags. Otherwise the current forecast is
on track and no updates are needed at this time. /13
PREV DISCUSSION... /issued 840 AM CDT WED AUG 10 2016/
DISCUSSION...See updated information for land areas below.
UPDATE...Updated the morning forecast package to lower the rip
current risk for the day to moderate. A stronger southwesterly wind
flow is projected for Thursday into Friday so have postponed the high
risk until Thursday at this time.
PREV DISCUSSION... /issued 631 AM CDT WED AUG 10 2016/
DISCUSSION...See updated information below.
UPDATE...Did a quick update to the current zone forecast to
include patchy fog for all areas through 9 am this morning. 32/ee
MARINE...Did a quick update to the current marine forecast to
adjust the locations under a small craft advisory...removing most of
the inland bays and sounds...excluding the lower end of mobile and
the Mississippi Sound east of Pascagoula. A small craft advisory is
in effect for the lower end of Mobile bay and the Mississippi Sound
from thu morning through early thu evening. 32/ee
AVIATION...
12Z issuance...MVFR to IFR conditions mostly in and around showers
and thunderstorms through 11.12z. Better coverage of showers and
thunderstorms beginning later this morning continuing into the
evening hours. Winds will be light and variable early today becoming
southwest 5 to 10 knots later this morning continuing through early
this evening...then becoming southeast later this evening continuing
through early thu morning. 32/ee
PREV DISCUSSION... /issued 506 AM CDT WED AUG 10 2016/
NEAR TERM /Now Through Wednesday night/...Little change from
previous package expected as mid to upper low near and just off the
central Fl panhandle coast will continue to track east through
tonight reaching the lower Ms river valley and adjacent gulf waters
of Louisiana by 12z thu. As this system nears from the east today
slightly better forcing in the mid levels is noted rotating around
the upper low combined with very deep moisture in the boundary
layer...pwats around 2.4 inches...and marginal sfc based capes
generally ranging from 1000 to 1600 j/kg leading to much better
coverage of showers and thunderstorms for most areas through
tonight...initially along the immediate coast and offshore early this
morning then spreading inland by late morning and afternoon...then
continuing along the immediate coast of NWFL and Al and offshore late
this evening through 12z thu. As mentioned throughout the week
significant rainfall amounts will come mostly from individual cells
dumping up to 2.5 inches or slightly better in an hour or so with
some training of cells also possible...generally moving from east to
west. As a result a flash flood watch will continue for lower
sections of the forecast area today and tonight...issued for all
areas in NWFL...all areas in Mobile and Baldwin counties in Al and
Stone and George counties in inland southeast Ms. With slightly
better forcing also noted a few stronger thunderstorms will also be
possible today occurring mostly during the afternoon and early
evening hours or during max heating. Gusty straight line
winds...frequent cloud to ground lightning and torrential rainfall
will be the main threats. As for temps with better clouds and rain
coverage expected today's highs will be a bit below seasonal averages
ranging from the mid to upper 80s over much of the eastern half of
forecast area including all areas along the coast...and the upper 80s
to near 90 to the west. Lows tonight will continue to range from the
mid 70s inland and the upper 70s to near 80 along the immediate
coast. 32/ee
SHORT TERM /Thursday Through Friday night/...The GFS/ECMWF and NAM
models all have the stacked 925-700mb low pressure system over
southern Mississippi Thursday morning, with the NAM closest to the
forecast area. The models then diverge in their solutions thereafter
with the ECMWF moving the system west-northwestward toward northeast
Louisiana, followed by the low filling and evolving into an open
wave after reaching the Mississippi River. The GFS moves the system
northwestward toward southeast Arkansas, followed by the low filling
and evolving into an open wave before reaching the Mississippi
River. And lastly the NAM is very aggressive deepening a pair of
925-700mb low pressure systems over the extreme northwest portion of
the forecast area, along with a pair of closed lows reflected at the
surface. Precipitable water values will also remain very high,
ranging from 2.3 to 2.6 inches on Thursday. Slightly drier air will
move into the region from the east Thursday night and Friday will
lower the precipitable water values across the eastern portion of the
forecast area to around 2 inches.
As upper level disturbances rotate around the upper level low to our
west along with decreasing stability during the daytime hours,
maintained definite rain shower and thunderstorm activity across the
southern and western portions of the forecast area throughout the
day Thursday with likely coverage elsewhere. Likely to definite rain
shower and thunderstorm activity will also occur on Friday, with the
best occurring across our western zones closest to the exiting upper
low. Additional rainfall totals through the short term should range
from 2.5 to 5 inches southwest of a line from Waynesboro MS to
Pensacola FL, and from 1 to 2.5 inches northeast of this line.
Localized higher rainfall amounts in a short period of time are
certainly likley near areas of strong convection.
High temperatures both Thursday and Friday range from 84 to 89
degrees. Low temperatures each night will be in the mid 70s inland
areas with upper 70s along the immediate coastal sections. /22
LONG TERM /Saturday Through Tuesday/...With the weak surface trough
exiting the region before the weekend, a surface ridge extending from
the western Atlantic across the northeast Gulf of Mexico and southeast
states will occur over the weekend into early next week. Likely rain
shower and thunderstorm activity is still forecast northwest of I-65
on Saturday with scattered coverage elsewhere. A continuing downward
trend in rain chances will occur throughout the long term as drier
air moves into the region. Expect a return to a more diurnal
convective pattern with scattered coverage during the daytime hours
Sunday through Tuesday and isolated to scattered coverage overnight.
Additional widespread rainfall totals on Saturday should only range
from 0.25 to 0.5 inches. Little change in the overall temperature
pattern is expected. /22
MARINE...Scattered to numerous showers and thunderstorms will
continue to form over much of the marine area today and continue
through Fri as a broad upper low near the Fl panhandle coast and
offshore continues to track eastward. Showers and thunderstorms will
generally move from east to west with gusty straight line
winds...dangerous lightning and torrential rainfall being the main
threats. Waterspouts will also be possible. A moderate to strong
southwest to westerly flow will slowly build over the marine area
today...and continue through friday morning. Seas up to 6 feet well
offshore can be expected with choppy to rough conditions on area
bays and sounds. As a result a small craft advisory is in effect for
the offshore waters of Al and NWFL through early Fri morning...also
including some inland bays and sounds thu into early fri. 32/ee
