Area Forecast Discussion...UPDATED
National Weather Service Mobile AL
1229 PM CDT Fri Jun 7 2019

.DISCUSSION...Updated for latest aviation discussion below.

&&

.AVIATION...
18Z issuance...Line of convection approaching the I-65 corridor
early this afternoon. Main hazards to approaches and departures
will be brief strong/variable wind gusts and reduced vsby to LIFR
categories with passage of +TSRA thru 07.19Z for MOB and BFM and
for PNS thru mid afternoon. Once convection moves out, cig bases
lift to mid to high levels and vsby improves. /10

.PREV DISCUSSION... /issued 1032 AM CDT Fri Jun 7 2019/

DISCUSSION...See updated information for land areas below.

UPDATE...Morning upper air map analysis shows a southern stream
upper level low spinning over Arkansas. Surface low pressure was
centered over extreme northwest MS. A frontal boundary intersects
the low and extends across central LA into eastern TX. A lead mid
level impulse was ejecting east northeast out of the base of this
system and has aided in the initiation of scattered showers and
storms within a very moist and unstable environment over the
central Gulf coast. PWATs range from 1.7 to 2 inches and latest
surface based CAPE values range from 2000 to 4000 J/KG. The
highest in this range aligned over the coastal counties.
Forecasters have been watching the strongest storms moving over
the interior this morning. An assessment of the convective wet
microburst potential today suggests a better potential for strong
to perhaps briefly severe, damaging wind gusts in excess of 60 MPH
with some of the storms. Considering the presence of strong
instability, deep Gulf moisture, the position of the upper trof
and surface frontal boundary over the Mid-South all favors an
increased coverage of showers and storms today. This is advertised
in the latest forecast and will not change. The heavy rain threat
also continues and remains elevated over the southern zones. With
efficient warm rain processes, heavy rain rates in a short period
of time could lead to instances of flooding over lower lying and
urban areas subject to poor drainage. With pre-cursor heavier
rains having fallen over the past couple days (upwards of 3 to 6
inches) the moist antecedent soil conditions favor more of an
elevated flooding risk over the coastal zones. Thus, flash flood
watches remain in effect from portions of Mobile Co. AL, eastward
to Okaloosa Co. FL.

Along the beaches, rip current risk remains high. Minor coastal
flooding is possible this afternoon and into early this evening
due to moderate to occasionally strong onshore flow coincident
with onset of high tide. /10

PREV DISCUSSION... /issued 648 AM CDT Fri Jun 7 2019/

DISCUSSION...Updated for latest aviation discussion below.

AVIATION...
12Z issuance...VFR cigs and vsbys will persist this morning at
KMOB and KBFM, with temporary reductions in cigs to MVFR along
with showers at KPNS. Coverage in showers and thunderstorms will
increase by early this afternoon and continue through early
evening before diminishing in coverage. Once again, temporary
MVFR reductions will be possible with any convection. Southwest
winds will increase across the area later today and become gusty
at times.

VFR cigs will return this evening but there could be some lower
cigs late tonight under continued moist southerly flow. A few
showers and potentially an isolated storm will be possible again
overnight tonight. /JLH

PREV DISCUSSION... /issued 509 AM CDT Fri Jun 7 2019/

NEAR TERM /Now Through Friday night/...Early morning water vapor
imagery shows an upper level low spinning near the ArkLaTex
vicinity, while a southwest flow aloft prevailed across the north
central Gulf Coast region well in advance of this feature. An
associated area of surface low pressure was located from the
ArkLaTex to northern portions of MS, while a warm front extended
southeastward from this feature across northern and central AL. A
very warm and moist surface airmass is in place across our CWA to
the south of the boundary early this morning with temperatures and
dewpoints ranging in the mid 70s to around 80 degrees. Radar has
been fairly quiet the past few hours, though narrow bands of
showers have been recently forming along discrete boundaries
across coastal portions of southwest AL and the northwest FL
panhandle.

The forecast challenge today and tonight, and really through the
weekend will continue to focus on the potential for heavy
rainfall and perhaps a few strong to severe storms. Looking back
at regional dual polarization storm total rainfall accumulations
from the past 24-48 hours, the heaviest swath of rain has impacted
locations from southern Mobile/Baldwin counties in AL, to much of
the western FL panhandle, where widespread 3 to 5 inches of rain
has fallen, with localized totals over 6 inches. Despite the heavy
rainfall, recent dry antecedent conditions have so far precluded
flooding reports, but these recent heavy rains may have acted as
a primer to support an increased flooding threat today through the
weekend.

Deep layer moisture will gradually increase across our forecast
area within the southwest flow today and tonight ahead of the
slow approaching upper low pressure system and trough axis to our
west. Showers may initially be rather scattered in coverage early
this morning, before becoming more numerous to widespread later
this morning into this afternoon. We will continue to show an
uptick in POPs today, with 70-80% coverage returning by this
afternoon. The high dewpoint airmass will allow for plentiful
instability today, with MLCAPE values looking to average between
1500-2500 J/KG. This unstable airmass, along with some drier air
returning aloft today may be supportive of damaging wind gusts
with the stronger storm cells that develop today. The SPC Day 1
outlook places our entire area in a Marginal severe risk, which
looks reasonable. Another couple of rounds of showers and
thunderstorms may spread across the region this evening into the
overnight hours tonight, with indication in some of the high
resolution guidance of more heavy rainfall near the coast. Given
the recent heavy rains along the coast, with potential for more
training showers and storms through tonight, we have opted to
extend the Flash Flood Watch for the western Florida panhandle and
central and southern portions of Mobile county through tonight
(and also into Sunday, see additional details below), as heavy
rains within a short period of time could result in localized
flash flooding over these areas.

Finally, a HIGH rip current risk continues today and tonight (and
through the weekend) given persistent moderate to occasionally
strong onshore flow, high tidal ranges, and 3-4 ft, 6 s period
swell. The high tidal ranges and onshore flow may result in
another bout of minor coastal flooding along portions of Mobile
Bay around the time of high tide late this morning into early this
evening. A Coastal Flood Advisory will be in effect. /21

SHORT TERM /Saturday Through Sunday night/...The wet weather
pattern will continue into the weekend as the moist southwest flow
aloft persists ahead of and along the base of the approaching
upper level trough. Several shortwave impulses advancing over the
region will result in additional rounds of showers and storms
Saturday through Sunday night, and will keep POPs high through
this time frame. Short range and high resolution/convection
allowing models all point that coastal portions of Mobile and
Baldwin counties, as well as much of the western Florida panhandle
could receive an additional 3 to 6 inches of rain, with localized
totals over 8 inches through Sunday afternoon. The Flash Flood
Watch has been extended for this portion of our CWA through early
Sunday evening. Seasonably warm and humid conditions are otherwise
expected through the weekend. /21

LONG TERM /Monday Through Thursday/...The slow moving upper
level low that brought heavy rain to the Deep South over the
weekend will continue to slowly move east and begin to gradually
fill. Broad mid and upper level troughing will persist over the
region through Tuesday. A stronger northern stream shortwave
should dive southeast across the Middle Mississippi Valley by
Tuesday and into the Southeast by Wednesday.

At the surface, a cold front will advance through the Deep South
Tuesday through Wednesday. The deep moisture axis that will be in
place at the start of the long term forecast period will be
shunted southeast of the region by mid week. Chances for showers
and thunderstorms will remain in the forecast until the frontal
boundary moves southeast of the region. Surface high pressure will
finally build in from the northwest by the end of the forecast
period with a return to dry weather. Temperatures should remain
near seasonal normals through the extended forecast period.

JLH

MARINE...A moderate to occasionally strong onshore flow will
continue through the weekend in response to an approaching low
pressure system. An offshore flow develops late Monday in the wake of
a cold front moving southward across the marine area. Periods of
scattered to numerous storms will occur through Sunday, with some
storms producing heavy rainfall, frequent lightning, gusty winds and
waterspouts.
