Near record heat and dry weather memorial day and Tuesday...

Near term this late afternoon through through memorial day ...

this afternoon... Main headline for the rest of this afternoon is
the heat with highs in the mid 90s to around 100 degrees. Hottest
max temps will be in SE ga at about 100 to 103. Though scorching
temps, dewpoints will bottom out this aftn in the lower to mid 60s
most areas which will keep heat indices below local heat advisory
criteria. Sea breeze relief expected for the coastal areas, but
unfortunately the sea breeze will be moving relatively slow given
weak synoptic winds. We expect some records to be broken or tied
this afternoon. A few pop up showers with an isolated thunderstorm
continues to be shown by the hrrr over interior southeast georgia
south of highway 32 and over interior northeast florida mainly north'
of i-10 this late afternoon and early evening.

Tonight... A slow decline in temperatures again into the overnight
hours. High pressure and upper level ridge provide a mostly clear
night with low temperatures dropping into the upper 60s inland
to mid 70s coast.

Memorial day Temperatures will continue to be well above average
with near record or record MAX temperatures. Dry conditions across
the majority of the region. Surface ridge will dip slightly southward
with one main high pressure area east of the florida peninsula with a
second high pressure center over the northeast gom. The upper ridge will
remain intact over the region. Light southwest to west winds anticipated
across the region. Seabreeze merger possible between i-75 and highway
301 south of i-10 for the slim possibility of very limited popup
showers during the afternoon.

Short term Tuesday through Wednesday night ...

upper ridge remain anchored over the region during this period with
hot weather pattern persisting. A weak trough of surface low pressure
will stretch down the southeast coast Tuesday, into the interior
sections near the fl ga border. The NAM indicates, there could be
just enough convergence and increased moisture associated with the
trough for afternoon and evening convection Tuesday south of ga
highway 84 and along and north of i-10. Subsidence under the upper
ridge, will be a limiting factor however. So, much of area should
remain dry. Dry weather is expected then for Wednesday as surface
high building across from the east. The well- above normal temperatures
will continue through this period, with highs approaching record
levels each afternoon.

Long term Thursday through Saturday ...

high pressure at the surface and aloft will persist over the
region into Thursday. Pretty steady state on the temperatures
Thursday with low 90s beaches, mid to upper 90s most other
locations with altamaha river basin region near 100. The fairly
persistent ridge will then slide to the south over florida late
Thursday through Saturday with zonal flow aloft over georgia. A
cold front will approach northern georgia from the northwest
Friday, as the 500mb flow remains zonal. At this time, looks like
the front will weaken as it passes into the region Friday night
and remains near the coast Saturday. There looks to be enough
convergence, boundary layer moisture and instabilty east of
highway 301 to the coast with diurnal convection possible Saturday
as residual and hardly discernible frontal boundary resides near
the coast. Have opted to only have 20 to 30 pops Saturday. But
early indications are that rainfall amounts won't put much of a
dent in our precipitation deficits. Temperatures will trend very
slightly downwards Friday and Saturday. However, they are still
forecasted to remain above normal, but not as hot as during the
near and short term period.

Aviation
Atlantic sea breeze taking its time moving into the coastal areas
today given southwest to west flow impeding inland progress. Wind
shift to the southeast at about 10 kt will start by 18z-20z, for
coastal tafs. As the sea breeze weakens again tonight, winds will
lessen and shift to south-southwest toward early morning. Another
mid to late day sea breeze on memorial day. Sunny skies at this
time, but some sct clouds around 6000-10000 ft expected into late
evening based on satellite trends and rap guidance. No vsby issues
expected late tonight, outside of some shallow fog and local
smoke from wildfires.

Marine
Ridge of high pressure maintains over the waters throughout the
weekend into early next week. By mid-week, the high pressure
shifts south and east, 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. Slight dip very late in the week with slight chances for afternoon
convection.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
