Area Forecast Discussion National Weather Service Jacksonville FL 451 PM EDT Tue Jul 14 2020

NEAR TERM [Through Tonight].

A hot and humid afternoon continues across the region as scattered storms have formed due to sea breeze interactions in the hot and moist airmass south of a weak area of low pressure just north of the region. Maximum heat indices have peaked in the 100-106 degree range early this afternoon under light west southwest flow in the low and mid levels.

Dry air aloft was observed in the mid levels on water vapor imagery and on this morning's sounding and current GOES satellite Precipitable water estimates of 1.50 to 1.75 inches should keep the coverage of storms in the scattered range with warm mid level temperatures near -5 degrees Celsius helping to suppress storm coverage as well. However, storms that do form will have the potential for strong to marginally severe downburst winds of 40-60 mph due to high levels of DCAPE in the environment ranging between 1,200 and 1,500 J/kg. Slow storm motions aloft could also keep a threat for locally heavy rains, but drier air and lower storm coverage should keep this threat on the low side. Storm activity will continue until a few hours after sunset when storm activity should wind down. Some mid and high level clouds leftover from this afternoon and evening convection will linger overnight and this along with light winds from the west southwest should prevent any significant fog development.

Hi temperatures peaking in the mid to upper 90s over interior SE GA and NE FL and topping out in the low 90s along the coast will cool down this evening into the upper 70s along the coast and the mid 70s inland overnight.

SHORT TERM [Wednesday Through Thursday Night].

Wednesday, the period will begin with a weak troughing over SE GA into the western FL panhandle with a weak upper low moving westward along the Gulf coast towards LA and TX as surface high pressure situates over the NE Gulf of Mexico. Mid/upper level ridging will be over TX with additional with ridging aloft forming over the NE US that will nudge southward over the east coast Wednesday afternoon into Thursday. This will bring drier air over the region in the low and mid levels as the low level flow shifts easterly off of the Atlantic with Precipitable water levels falling to below normal levels with values ranging 1.30 to 1.50 inches.

Some initial showers will move onshore on wednesday as the easterly winds come onshore in the midday hours with the easterly winds colliding with the Gulf coast sea breeze in the early to mid afternoon hours between the I-75 and highway 301 corridors. Scattered showers and more isolated coverage of storms will be expected.

High temperatures will lower to more near normal levels along the coast on Wednesday and Thursday with above normal temperatures inland. Highs both Wednesday and thursday will be in the low 90s from I-95 eastward and near 90 at the beaches with mid 90s along and west of Highway 301. Lows on Thursday will stay warm at the coast with readings in the mid to upper 70s while inland areas cool into the low 70s in the drier airmass.

LONG TERM [Friday Through Tuesday].

East to southeasterly flow will predominate during the long term period with mid/upper level ridging north of the region. An upper level wave will move over the Fl Peninsula from the Bahamas Friday into Saturday with an axis of high pressure moving over NE FL on Sunday and then positioning northward over SE GA Monday into Tuesday. Moisture levels on Friday will increase into Saturday as the upper level wave moves over central FL with scattered to numerous storms over NE FL and less coverage over SE GA. As the wave moves into the Gulf of Mexico, low level flow will become southeasterly on Sunday and persist through Tuesday allowing scattered to numerous showers and storms coverage to shift into SE GA while shower coverage increases over NE FL with increased moisture off the Atlantic. Hi temperatures will be near normal through the end of the period across the area with highs in the low 90s inland and near 90 at the beaches. Low temperatures will be near normal with low 70s inland and the mid to upper 70s at the coast.

AVIATION. [Through 18Z Wednesday]

Widely scattered thunderstorms already beginning to develop this afternoon along the Gulf coast seabreeze, spreading from GNV northeastward towards VQQ/SGJ/CRG/JAX. Brief MVFR or lower conditions possible with these storms, but otherwise VFR should prevail with light winds generally from the southwest.

MARINE.

Scattered showers and thunderstorms will occur over the waters through this evening as weak troughing stays positioned just north of the Georgia waters this evening. High pressure will build from the northeast on Wednesday through Friday with light winds becoming easterly and drier conditions offshore. An easterly wave will pass south our local waters late Friday into Saturday, with increasing shower and thunderstorm coverage expected this weekend.
