1041 am edt Mon aug 21 2017

Near term [through today]
Weak tropical wave will cross the region today in the wake of the
upper low exiting westward across the gulf. Deep layer moisture
has increased, with 12z pwat back above 2 inches in deep
southeasterly flow. This should lead to better coverage of
afternoon showers and storms, especially across the big bend and
panhandle.

As for local eclipse viewing, the chances for clearer skies
increase as you move northward. Current trends don't look all that
good for western big bend and eastern panhandle coasts, as morning
clouds and offshore convection are widespread attm. Farther
inland, it will be a bit hit and miss as the afternoon cumulus
field develops and scattered showers kick off. However, for many
areas, there should be enough breaks in the clouds to see the
~80-90 obscuration this afternoon.

Prev discussion [642 am edt]
Short term [tonight through Wednesday]
The upper low across the central gulf will continue moving
westward and away from the area. Western atlantic ridging will be
draped across the southeast with the axis just north of our area.

However, the ridge axis will shift southward in response to a
deepening trough across the southern plains moving into the
southeast us. Tropical moisture increases in earnest this period
with pwats approaching 2.3 inches with moisture distributed
throughout the column. What this means is a return to the normal
rain chances for this time of the year, roughly 40-50% chance each
day especially in the afternoon and early evening hours. Highs
will be in the lower 90s.

Long term [Wednesday night through Monday]
Frontal boundary associated with the eastern us trough will move
southeast and push through our area Friday. Low pressure is
progged to develop on the front Saturday off the florida east
coast in response to a trailing shortwave trough, deepen through
Monday then slowly move northeast. Rain chances will continue in
the 40-50% chance range Thursday through Sunday. Drier air on the
backside of the low off florida plus drier air moving south off
the appalachians will put a halt to the higher rain chances
Monday. Highs this period will be in the upper 80s to lower 90s.

Aviation [through 12z Tuesday]
A brief period of MVFR to ifr vsbys remains possible at vld over
the next 1 to 2 hours before conditions quickly improve.

Otherwise,VFR conditions are expected outside of any tsra this
afternoon. Southeasterly winds below 10 kts will prevail at all
sites outside of any TS activity.

Marine
Generally light winds and low seas are expected through the next
several days.

Fire weather
Outside of marginally low dispersions across the florida panhandle
late this afternoon and again on Tuesday, hazardous fire weather
conditions are not expected through the next week.

Hydrology
Localized flooding is possible with stronger storms as rain
chances return to normal. There are no widespread flooding
concerns this period.

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.
