449 am cdt Mon aug 26 2019

Near term now through Monday night Weak surface high
pressure ridging over the area from the northeast will weaken
further through tonight as a mid upper level shortwave axis
centered just west of the area early this morning lifts east-
northeast today and tonight. This mid upper level feature will be
weakening as it lifts across the area today, but will still
provide enough dynamics to support likely showers and
thunderstorms. No real locally noted low level features to focus
on in the near term, but an extremely moist airmass will be in
place with pwats primarily in the 2.2 to 2.4 inch range. All of
this moisture will be pooling up south of a weak stationary
boundary stretching from northwest to southeast across mississippi
and alabama. All of this will provide a continuation of a fairly
unsettled weather pattern across the region in the near term
period. Currently have some areas of rain and showers over the
region, and high-res models indicate a general increase in
precipitation across the region through the morning hours,
especially over the western half of the forecast area. By this
afternoon, expect scattered to locally numerous showers and storms
across the entire area. With the very moist airmass, still
expect periods of heavy rain in some locations today. While heavy
rainfall is possible across the entire area today, it will be
most likely over the western half. After coordination with wpc and
surrounding offices (lix and jan), we have adjusted our slight
risk of excessive rainfall slightly to the west. It is over that
area where rainfall totals of over 2 inches, locally 3 inches,
will be possible today. Further east rainfall totals of 1 to 2
inches possible. We will not be issuing any flash flood
advisories, but it should be noted that rainfall rates will at
times be supportive of localized flash flooding, especially over
the western half of our forecast area. Severe potential in this
environment remains low as the wind profile will be lacking in the
needed shear, however MLCAPE values ranging from 1500-2500 j kg
will provided enough energy for some strong thunderstorms embedded
within the widespread rain and showers. With the widespread
clouds and precipitation expected today, highs will generally be
in the low to mid 80s across most of the area, although a few
upper 80s will be possible in some locations. Lows tonight will be
in the lower 70s for most areas except along the coast, where mid
to upper 70s are expected. 12 ds

Short term Tuesday through Wednesday night Lead upper level
trof axis aligned from the appalachians, southwest across the ms
sound Tuesday morning de-amplifies a bit going thru the course of
the day. Embedded in the trof axis, a stream of deep layer
moisture characterized by pwats between 2.0 and 2.2 inches
remains in place. Main contributor to forcing ascent for
convective development will come from the passage of mid-level
impulses thru the base of the upper trof position. The only
surface contribution to lift looks to be weak mesoscale boundaries
and perhaps a slow northeastward advance of a coastal sea-breeze.

The more substantive surface boundaries will be to our northeast
and northwest, with a warm front lifting northeast and weakening
over the southeast and a front moving out of the southern plains
to thru the mid-south late in the day Tuesday. Enough upper level
support and high amounts of deep moisture suggests that showers
and storms will be likely into Tuesday.

To our north and west, long-wave upper trof amplifies as it
ejects eastward out of the northern high plains Tuesday night to
across the great lakes Wednesday. Surface front makes steady
progress approaching the northern zones Wednesday morning
southeastward to near the coast by evening. Chance of
showers storms along the us highway 84 corridor and more likely
elsewhere Wednesday as the front approaches. Front moves off the
coast Wednesday night with drier air in its wake bringing a
reduction in rain chances.

Gridded daily highs range 87 to around 91 Tuesday with similar
numbers for Wednesday. Lows in the 70s Tuesday night trend lower
Wednesday night due to frontal passage. May see several locations
in the interior seeing lows settling into the mid to upper 60s.

10

Long term Thursday through Sunday With front into the gulf
Thursday, a sunny and drier day expected. Medium range weather
models show a narrow mid level ridge setting up from the
southwest atlantic into ms Friday and Saturday. In the evolving
deeper level easterlies on the southern periphery of the ridge
feature, a tap of atlantic moisture is driven westward over the
local area into the weekend. This in combination with a westward
moving inverted trof axis over the gulf brings a return to rain
chances for the weekend.

Highs range from the upper 80s to lower half of the 90s. Coolest
night Thursday night with overnight lows sinking into the 60s for
much of the area north of i-10. The lowest near 63 over the
northwest zones north of a line from grove hill al to waynesboro
ms. The cool down will be brief as overnight lows warm the
remainder of the period.

A look at the tropics, tropical storm dorian is forecast by the
national hurricane center (nhc) to impact the greater antille's
island of hispaniola as a hurricane early Thursday morning. The
mountainous terrain will likely cause a disruption weakening of
dorian's inner-core as it moves over the island. NHC forecasters
keep enough of the inner-core intact though, forecasting a
depression moving northwest through the southern bahamas into the
weekend. Will continue to keep a close eye on dorian in the coming
days. 10

Marine A light to moderate south to southwest flow is expected
today through late Tuesday night or early Wednesday. Low pressure
developing off the eastern seaboard will lift northeast through the
week, allowing a cool front currently over the plains states to drop
down toward the gulf coast and then offshore into the northeastern
gulf by late Wednesday. With this frontal passage, a light to
moderate northwest to northerly flow is expected late in the week.

Seas build slightly around midweek, up to 2 to 3 feet well offshore
but in general will be 2 feet or less through the period. Periods of
showers and thunderstorms can be expected over the coastal waters
through the period as well. 12 ds

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
