809 FXUS62 KTAE 231850 AFDTAE AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 250 PM EDT Wed Jul 23 2014 .Near Term [Through Today]...
-- Changed Discussion --
Scattered showers and thunderstorms have developed this afternoon along and ahead of the sea breeze over the panhandle and western Big Bend. The diurnally driven convection will dissipate shortly after sunset yielding to party cloudy skies and patchy fog overnight. Lows will once again be around 70 degrees. .Short Term [Tonight Through Friday]... The large scale period commences aloft with dissipating cutoff low to our west, however remnants become increasingly absorbed by Nrn stream trough Thurs and deepening into full latitude trough over SE states thru the period. At surface, Mid-South cold front drops Swd, albeit with limited moisture, to Srn AL/GA by end of period shunting Ern ridge progressively SEWD into Atlc. All this results in strengthening deep layer WSW flow with PWATs hovering around 1.9 inches. Expect 30-50% POP gradient, S-N on Thurs and W-E on Fri focused across east half of CWA and in aftn. With increased dynamics, steeper lapse rates and higher dew points, strong storms with ample lightning and gusty winds are possible each day and we cant discount isold pulse severe with damaging winds and locally heavy rain especially with seabreeze/boundary clashes. High temps will reach the low to mid 90s, a little higher on Thurs with heat indices from 90 to 103 highest Thursday and east. .Long Term [Friday Night Through Wednesday]... The region will be dominated by a typical summer pattern through Sunday. As a result, expect isolated afternoon/evening rain and thunderstorms. Monday an upper level trough moves in and increases afternoon/evening precip chances. A stationary boundary is expected to linger over the area Tuesday and Wednesday bringing increased rain chances in the Big Bend Region. In addition to the increased rain chance expect abundant cloud cover. It will be slightly cooler and less humid Tuesday and Wednesday...particularly in the Alabama and Georgia counties.
