Area Forecast Discussion...UPDATED
National Weather Service Mobile AL
627 PM CDT Tue Jun 6 2017
.DISCUSSION...Updated for latest aviation discussion below.
&&
.AVIATION...
00Z issuance...An upper low spinning around off the Ms Gulf coast
will meander eastward tonight through Wednesday. This system,
working with a surface boundary along the northern Gulf coast with
bring a slowly eastward shifting area of MVFR/local upper LFR
CIGS to the area overnight into Wednesday. An overall decrease in
precip coverage is expected Wednesday.

.PREV DISCUSSION... /issued 320 PM CDT Tue Jun 6 2017/
NEAR TERM /Now Through Wednesday/...Weather maps show low
pressure, surface and aloft over southeast Louisiana with abundant
cloud cover in place. Radar has been unusually tranquil thus far
given the presence of the low nearby and high amounts of deep
moisture, but forecasters are beginning to see a resurgence in
development over the central Gulf coast, which should expand in
coverage thru the remainder of the afternoon. The overall movement
of the synoptic scale low has been slow, which could contribute
to localized flooding in lower lying areas that experience poor
drainage of storm water. Weak wave of frontal low pressure is
progged to move very little tonight, positioned from the MS Sound
to the AL/northwest FL coastal waters. Given the very slow
movement, if any at all, of the low into tonight and the
availability of high amounts of deep moisture, there are concerns
that some areas could see localized flooding problems from slow
moving storms which could potentially become fixed in place for
several hours. Given the low confidence in timing and placement of
these areas, will refrain from issuance of a flash flood watch at
this time and will let later shifts assess convective trends.
However, feel it prudent to mention locally heavy rain possible in
gridded forecasts this evening over the southern zones given that
these areas will be closer to the low position and best forcing.
Overnight lows in the mid to upper 60s interior to lower to mid
70s coast.
Frontal zone, attendant waves of low pressure along it, shifts
southeast of the local area Wednesday. As this system departs,
rain chances trend lower from northwest to southeast thru the day
as drier air filters into the deep south. Daytime highs on
Wednesday, 83 to 87. /10
High risk of dangerous to potentially deadly rip currents continues
along area shores thru Wednesday morning due to increased tidal
ranges and modest swell. /10
SHORT TERM /Wednesday night Through Friday night/...An upper trof
over the eastern states slowly weakens through Friday night as an
embedded upper low over the interior eastern states moves into
the New England area then ejects well off to the northeast. A
surface low located initially over the extreme northeast Gulf
Wednesday evening moves to just off the New England coast through
Thursday night, with a surface ridge meanwhile building into the
region which persists through Friday night. Drier deep layer air
will have already shifted into much of the forecast area at the
beginning of the period, except for generally around the western
Florida panhandle, but drier air shifts into this remaining
portion during Wednesday evening. Have gone with slight chance
pops for a portion of the western Florida panhandle, but dry
conditions otherwise follow through the period. Highs will be in
the mid to upper 80s each day while lows generally range from the
lower 60s inland (except a bit cooler Thursday night) to the mid
to upper 60s near the coast. /29
LONG TERM /Saturday Through Tuesday/...An upper ridge over the
Plains amplifies while shifting into the eastern states through
Sunday, then moves off into the western Atlantic through Tuesday
as an upper trof advances across the western states into the
Plains. A surface ridge over the Gulf coast states shifts slightly
southward to be oriented along the northern Gulf coast but
otherwise maintains a light southerly flow over the forecast area. Deep
layer moisture over the region improves significantly on Sunday
with the departure of the upper ridge, with elevated values
persisting through the remainder of the period. Another dry day
is expected for Saturday, then chance pops follow each day with
daytime heating and a series of generally modest shortwaves
resulting in isolated to scattered convection. Highs will be in
the mid to upper 80s each day. Lows Saturday night will be mostly
in the mid 60s inland ranging to lower 70s at the coast then each
remaining night will be near 70 inland with mid 70s at the coast.
/29
MARINE...Wave of frontal low pressure moves little over the
coastal waters tonight and brings potential of numerous showers
and scattered storms. Winds, waves and seas will be locally higher
in and near storms. Locally heavy, visibility reducing rain is
also possible. Front moves well to the southeast during the day
Wednesday, bringing a lowering trend in rain chances while
maintaining an offshore component of flow. Offshore flow continues
Thursday and into early Friday with high pressure over the Lower MS
River Valley. A light onshore flow sets up over the weekend with a
chance of showers and storms returning to the forecast by Sunday.
