Near record heat and dry weather this memorial day weekend...

Near term Today and tonight...

currently... Under clear skies, temperatures have slowly come down
overnight from the record levels that were reached yesterday
afternoon. High pressure ridge stacked from the upper atmosphere
down to the surface remains over the area, leading to another
mostly clear overnight and early morning with patches of shallow
fog.

Today... High pressure 500 mb ridge strengthens back to 593-594 dm
as yet another reinforcing jet streak rounds the base of the
trough situated over the western conus. With this, expecting
another hot day featuring abundant sunshine and temperatures
quickly rising into the low to mid 90s before noon. The forecast
for MAX temperatures Sunday afternoon has increased 1-2 degrees
when compared to Saturday, especially across SE georgia as 850 mb
temperatures slowly increase to 20-21c. A large swatch of 100-102f
is forecast for SE georgia with mid to upper 90s for NE florida.

An east coast sea-breeze moves inland during the afternoon hours
providing a few degrees of relief for coastal locations. Broad
scale subsidence and deep layer dry air inhibits any chance for
precipitation with scattered cumulus developing during the
afternoon.

Tonight... After another blistering hot day, temperatures once
again decrease slowly into the overnight hours. High pressure and
upper level ridge provide a mostly clear night with low
temperatures dropping into the upper 60s and lower 70s.

Short term Monday through Wednesday ...

hot weather pattern to continue this period, as upper ridge
remains over region. A weak trough of surface low pressure will
stretch down the southeast coast Monday into Tuesday, with surface
high building across from the east Wednesday. As NAM indicates,
there could be enough convergence and increased moisture
associated with the trough for afternoon and evening convection
Monday and Tuesday. Subsidence under the upper ridge, will be a
limiting factor however. So, planning to introduce low chance pops
inland for Monday and Tuesday, but much of area should remain
dry. Dry weather is expected then for Wednesday.

The above normal temperatures will continue through this period,
with highs approaching record levels each afternoon.

Long term Wednesday night through Saturday ...

high pressure at the surface and aloft will continue across the
region into Thursday. The fairly persistent ridge will then slide to
the south late Thursday into Thursday night. A cold front will
approach from the northwest Friday, as the 500mb flow becomes more
zonal. At this time, looks like the front will weaken as it passes
through, but convection can not be ruled out. Fairly weak surface
ridging into Saturday, but diurnal convection will once again be
possible in the afternoon and evening.

Temperatures are expected to continue above normal this period, but
not as hot as during the short term period.

Aviation
PrevailingVFR conditions as winds remain weak under the ridge of
high pressure. Winds increase from the southeast during the
afternoon (18-19z) with the passage of the east coast sea-breeze.

Marine
Ridge of high pressure maintains over the waters throughout the
weekend into early next week. By mid-week, the high pressure
shifts southeast, and a tightening pressure gradient regime along
the coast will introduce the opportunity for increased winds and
higher seas, potentially near caution levels.

Rip currents: low risk of rip currents. Onshore winds increase
during the afternoon as the sea-breeze moves inland.

Fire weather
Hot and mainly dry conditions to persist.

While there are chances for afternoon convection Monday and Tuesday
afternoon, much of the region will remain dry, with temperatures
remaining well above normal. Hot and dry conditions expected again
Wednesday. Not as hot late in the week with chances for afternoon
convection.
