GMZ600 Synopsis For Pascagoula Ms To Okaloosa Walton County Line Fl Out 60 Nm Including Major Area Bays And Sounds- 403 Pm Cdt Sat Jul 21 2018
Synopsis..A broad surface ridge of high pressure will continue over the central and northern gulf through early next week, combined with a weakening frontal boundary shifting southward towards the northern gulf coast. With this pattern a moderate to strong westerly flow will continue over the marine area through Sunday evening shifting northwest late Sunday night as the week front moves offshore. Winds and seas will be locally higher with isolated to scattered Thunderstorms through early next week with best coverage generally east of pensacola through early next week.

national weather service mobile al
759 pm cdt Sat jul 21 2018

Discussion See updated information for land areas below.

Update Weather maps this evening shows a highly amplified
pressure trof at high levels from the ohio river valley to the
southeast while a deep layer ridge was centered over tx. Between
these two systems has been a conveyor belt allowing for the
southeastward movement of mid level impulses to help bring an
enhancement in lift within a very unstable and moist deep layer
airmass over the southeast. The bulk of evening convection
remains northeast of the local area where clusters of storms, with
a history of producing severe weather, were tracking southeast
out of the east central al and into west central ga. These storms
have also fired due to a region of pronounced mid level dry air
crossing southeast atop a frontal zone which has eased across the
tn river valley. There currently is no convective activity over
the local area due in large part to the presence of a weak capping
inversion in the lower levels as mentioned from previous shift.

This may erode some tonight and there are some indications in the
latest convection-allowing models (cam's) of some isolated to
scattered development over the eastern half of the local area. If
the cap is overcome, abundant mixed layer CAPE on the order of
3000 to 4000 j kg will be more than sufficient for updraft growth;
as a result there remains some potential for a few storms to
become severe. Main impacts would be severe convective wind gusts
in excess of 60 mph. Forecasters maintain a marginal risk of
severe weather mainly over the eastern zones. Will continue to
monitor. 10

near term now through Sunday ... Limited coverage of showers
and thunderstorms will continue through this afternoon and evening
mostly due to an elevated mixed layer above a shallow warm layer
that is advecting east generally around 2kft or less. This pattern
is a result of a deep layer ridge of high pressure to the west
shifting slightly east across the north central gulf states
through sun. Aloft very impressive CAPE values, lapse rates and
moisture content continues across the region possibly leading to a
few isolated to scattered thunderstorms developing later this
afternoon and this evening if the weak warm nose is overcome or
mixed. Although most of the convection will be somewhat elevated
if it does form enough mixing near the surface could result in
isolated cases of strong gusty winds with the larger
thunderstorms. Model soundings support this reasoning and continue
to show this warm nose through Sun afternoon which continues to
limit the coverage of showers and thunderstorms in the near term
period. Due to the current conditions mentioned above we will
continue with the limited threat graphic for severe weather
through this afternoon. With this pattern the best chance for any
measurable rain will be over the eastern half of the forecast area
generally east of the mobile tensaw delta for the next 24 hours.

Otherwise, the biggest concern in the near term period will be
dangerous heat index values across the region this afternoon and
during the day on sun. The higher values of 108 to 112 still look to
occur generally south of a line stretching from crestview fl to
hattiesburg ms during the late morning and afternoon hours through
sun. As a result a heat advisory will continue in these areas
through Sun afternoon. 32 ee
short term Sunday night through Tuesday night ... An elongated
north-south oriented upper low over the eastern states weakens to
an similarly oriented upper trof on Monday while a large and
strong upper ridge dominates the southwestern states. An
associated surface low will be located over the carolinas at the
beginning of the period, with a cold front extending southwestward
across the southern portion of the forecast area. The surface low
shifts slowly southward across georgia through Monday, and in the
process brings the cold front through the remainder of the
forecast area Sunday evening and into the extreme northeastern
gulf. Have gone with mostly dry conditions Sunday night except for
slight chance pops over a portion of the western florida
panhandle and south central alabama where some storms may linger
from the daytime into the evening hours and or develop on the
frontal boundary. While the frontal boundary will be located just
offshore on Monday, a series of shortwaves moves across the area
through the northerly flow aloft. Coverage of convection looks to
be limited by the strength of a warm nose located near 725 mb
with an elevated mixed layer (eml) otherwise present aloft. The
eastern portion of the area will be less affected by the warm nose
(close to the axis of the upper trof) while the western portion
will be more under the influence of the eastern periphery of the
albeit distant, but intense upper ridge. As such, have gone with
chance pops over the eastern portion tapering to slight chance
pops over the western portion. Some strong to possibly severe
storms can occur on Monday, mainly over the eastern portion of the
area.

The upper trof continues to weaken slightly during the remainder
of the period while the surface low likewise weakens and shifts
into the extreme northeast gulf, near or over the marine area. The
associated frontal boundary weakens during the period as well
while lingering over the extreme northeastern gulf. With the
weakening of the upper trof, warmer temperatures aloft spread into
the region and significantly decrease the EML over the area.

While this results in a lower potential for strong storm
development, mainly scattered convective development is still
expected as a series of shortwaves continue over the area within a
northerly flow aloft along with the close proximity of the
weakening surface low. 29
long term Wednesday through Saturday ... The upper trof continues
to weaken over the eastern states on Wednesday, then is replaced
by a broad, longwave trof which evolves over the eastern states
Thursday into Friday. The surface low located near or over the
marine area drifts northward into the forecast area on Wednesday
and weakens to a surface trof which in turn lingers through
Thursday. Have gone with chance to good chance pops for much of
the area on Wednesday and Thursday, except for likely pops over
the easternmost portion where a better convective environment
will be present (left over from the weakening upper trof). A
surface ridge builds gradually over the northern gulf through the
period, and will promote an onshore flow over the forecast area
for Friday into Saturday with scattered convective develop
expected each day. 29
marine... Hazardous conditions for small craft can be expected
through Sun evening in response to a moderate to strong westerly
flow mainly from a strong pressure gradient setting up over the
northern gulf waters over the weekend. As a result a small craft
advisory is now in effect for the open gulf waters of al and nwfl
from 0 to 60 nm out including the lower end of mobile bay and the
mississippi sound east of pascagoula, beginning at midnight tonight
continuing through 10 pm cdt Sun evening. Winds ranging from 18 to
23 knots with seas up to 7 ft can be expected over the open gulf
waters during the day on sun. Over most inshore waters waves will
range from 1 to 2 feet. 32 ee
