Near term now through Saturday An upper trough visible in water
vapor satellite imagery currently extends roughly from post-tropical
cyclone jose off the new england coast southwest into the
northeastern gulf. Ongoing scattered thunderstorms over the
southeastern states are being supported by strong daytime heating,
weakened static stability across the region, and upper level
divergence associated with a jet streak rotating around the western
side of the trough. Despite the dynamic support aloft, storms should
remain largely driven by heating and are thus expected to gradually
dissipate after sunset this evening. Until then, coverage will
increase into the late afternoon hours as storms drift from
northeast to southwest, with frequent cloud-to-ground lightning and
brief heavy downpours being the primary threats in the stronger
cells. Skies then clear out and light patchy fog will be possible
late tonight through sunrise Saturday. Low temps will range from the
upper 60's to around 70 inland and the low to mid 70's along the
immediate coast.

The aforementioned upper trough is bisected by a narrow ridge
building ahead of a very deep longwave trough over the western
conus. The northern half of the former trough, including the
remnants of jose, are caught up and swept east over the atlantic by
an embedded shortwave in the mid-latitude jet (currently situated
over southern canada). The southern half is pinched off, forming a
cutoff low which then begins to push south over the southeastern
u.S. Late tonight into Saturday morning. Our local area remains on
the "dry" side of this upper low Saturday afternoon and evening as
it retrogrades over southeastern alabama and the florida panhandle,
with only a slight chance for some isolated showers and storms
during that time. High temps reach the low 90's over southeast
mississippi and far southwest alabama, where less cloud cover will
allow for plenty of daytime heating. Over south central alabama and
the western florida panhandle, expect highs to stay a couple degrees
cooler (upper 80's to around 90) due to greater cloud cover
associated with the retrograding upper low. Look for convective
activity to increase over our area later in the weekend as the low
continues to drift to our west. 49

Short term Saturday night through Monday night Period begins
with the aforementioned fl panhandle mid-level upper low moving
westward. Clouds and the chance of rain both increase Saturday
night and into Sunday as the feature moves further west to be
located over coastal ms by dark on Sunday. On the east side of the
upper system is where our greatest rain chances will be. So,
Sunday expect a fairly good coverage of showers with scattered
thunderstorms from late morning on (and spreading in from the
southeast). Some of the most intense storms may produce localized
heavy rainfall given both higher absolute values of low level
moisture and moisture flux convergence (especially south of
highway 84 and closer to the coast and also across interior se
ms)convergence. Relatively higher rain chances continue into
Monday afternoon as regional static stabilities remain low due to
the presence of that feature. Shower and thunderstorm coverage
decreases Monday night as the upper low moved further westward.

Temperatures will average a few degrees cooler than normal on
Sunday afternoon, but it will be muggy.

The rip current risk may climb on Sunday, as the day begins with an
increasing easterly wind. It becomes more southeasterly as the upper
low moves further west. Eventually slightly longer period swell
will begin and there is a pronounced spring tide early next week.

The risk will remain elevated into early next week. The surf zone
forecast will likely be updated later today for Sunday. 23 jmm

Long term Tuesday through Friday On Tuesday, the upper low
fills and is advected back to the east, away from the region, in the
deep-layer mean flow as the pronounced deep-layer u.S. Western
trough advances slightly eastward into the plains. Scattered
showers and thunderstorms linger, but coverage should be a little
less each day this period. For the remainder of the period, back
to drier conditions as ridge builds over the gulf of mexico
through Friday. Will have to watch exactly how the western u.S.

Trough advances, forecast could change slightly for Friday. 23

Marine Winds and seas build slightly over the weekend as the
local pressure gradient tightens between a building ridge to the
north and hurricane maria east of the bahamas. Expect east to
southeast winds of 10 to 15 knots with gusts to around 20 knots
Saturday through Sunday night. Seas build to around 2 to 3 feet over
the weekend. The gradient relaxes again heading into next week, with
easterly winds around 5 to 10 knots and seas returning to around 1
to 2 feet Monday through midweek. Showers and thunderstorms will
remain possible through the forecast period, with the greatest
coverage currently expected Saturday night through Sunday. 49

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
