National Weather Service Jacksonville FL
154 PM EDT Mon Aug 3 2020

.Near Term.../through Tonight/...

Isaias will continue to track to the north northeast of the
forecast area this afternoon. Bands will continue to move onshore
around the system. With diurnal heating over land, especially
inland, convection will strengthen as these bands move through.
With loss of day time heating, convection will dissipate into the
overnight.

Low temperatures will run a little above normal Tonight.

&&

.Short Term.../Tuesday through Friday/...

A trough of low pressure will extend across the southeastern US
Tuesday, as high pressure builds well to the east. The resultant
surface flow will be from the south which will increase moisture
across the region. The combination of the trough, sea breeze
boundary convergence, along with the a moist airmass will provide
for scattered to numerous convection Tuesday, mainly in the
afternoon hours. With loss of day time heating activity will
dissipate into Tuesday night. A similar pattern is expected for
Wednesday, but the trough will be weaker. The region will be
between high pressure to the east northeast and a trough to the
northwest Thursday into Friday. The continued south flow will keep
moisture across the region late in the week with mainly diurnally
driven scattered to numerous storms expected.

Temperatures will trend a little above normal this period.

&&

.Long Term.../Friday night through Monday/...

A fairly persistent pattern with high pressure to the east and a
trough of low pressure to the northwest. This will lead to a
continued moist flow, with above normal precipitation chances.

Temperatures will trend near to a little above normal this period.

&&

.Marine...

Isaias will continue to track to the north northeast of the
region this evening, with conditions improving through the night.

trough across the southeastern US for the rest of the week.
