.NEAR TERM /THROUGH TONIGHT/...
Main Highlights Today and Tonight:
- High Risk of Rip Currents continues at NE FL/SE GA beaches
- Locally dense fog possible late tonight/early Monday morning
High pressure ridging continues today, which is starting to orient
more northeast to southwest across the region, and therefore more of
a east-southeast to southeast wind direction is being observed
today. PWATs are below 0.75 inches and therefore rain chances are
near zero despite the continuing onshore flow, with just a few
diurnal clouds through this evening, mainly towards the I-95
corridor. The main concern today continues to be a higher risk of
rip currents, especially at northeast FL beaches. Highs in the 80s
will be common again today, except near the immediate coast where
upper 70s are expected.
Tonight, just enough low level moisture will be in place for some
patchy to areas of fog expected across the interior, with most high
res guidance suggesting interior GA having the highest potential,
especially for locally dense fog. Otherwise, mostly clear besides a
some higher clouds starting to fill in from the west overnight, with
lows in the 50s inland and upper 50s to low 60s near the coast.
&&
.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
Main Highlights This Period:
- Patchy fog each morning, which may become locally dense.
- Dry weather persists
Ridging aloft will dominate Monday through Tuesday night, with only
a weak passing upper level shortwave on Monday and Monday night
bringing some occasional high clouds. Otherwise, moisture
remains very limited (PWATs below 0.75 inches) and will continue
the dry weather pattern with additional subsidence due to the
ridge aloft. At nighttime, the light to calm winds and mostly
clear skies will support late night and early morning fog, but
should be fairly shallow and transient given the lack of low
level moisture. Atlantic sea breezes expected each afternoon
with speeds up to 10-15G20mph. High temperatures will run above
normal, with inland temps in the upper 80s, with potential for
about 90 on Tuesday. Coastal highs will be limited to upper 70s
to around 80 both days due to onshore flow. Low temps moderate
only slightly with mid 50s inland and closer to 60 at the coast.
&&
.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
Main Highlights This Period:
- Dry weather
- Record highs likely
- Fire weather concerns remain
Mid to upper level ridging dominates Wednesday into early Thursday,
promoting continued dry conditions. By Thursday into Thursday night,
a dampening shortwave trough moving through the Appalachians and the
southeast CONUS briefly suppresses the ridge southeastward, though
limited moisture and weak forcing will keep things dry. The ridge
quickly rebuilds overhead Friday in the wake of the shortwave,
bringing back large scale subsidence and above normal highs.
By the weekend, increasing height falls to the west associated with
an approaching mid/upper level trough begin to flatten the ridge and
push it southward. This results in increasing southwest flow
through the column and some weak warm advection. A weakening cold
front may move into our area Sunday afternoon or Sunday night, but
with limited upper support and moisture, precip chances remain low.
At the surface, high pressure anchored to the east will maintain a
general southeast and south flow. The Atlantic sea breeze should be
moderate to strong each afternoon, though probably a bit weaker
Sunday as the flow begins to change ahead of the front. The higher
than normal heights will support highs near or exceeding record
highs each day during this period, with lower to mid 90s probable.
A check on ensemble data shows 20-30 percent of max temps exceeding
95 degrees on Friday and Saturday. Lows trend a little warmer than
they have been, with upper 50s to lower 60s transitioning to lower
to mid 60s by Sunday morning.
&&
.AVIATION /18Z SUNDAY THROUGH 18Z MONDAY/...
VFR is expected to prevail for most if not all of the forecast
period at this time. Southeasterly breezes around 10 kts will higher
gusts at times will ease later this evening. The only other
operational concern through the forecast period will be some FG/BR
potential early Monday morning. Confidence remains too low at this
time with probabilities currently under 10 percent at all terminals
except at VQQ, which have included MVFR vsbys accordingly.
&&
.MARINE...
High pressure ridging will be the prevailing feature through mid to
late this week, with flow gradually shifting more southeasterly over
the next several days. Elevated seas today over the area waters,
mostly from east swells, will gradually subside through this
week as well.
Rip Currents and Surf:
East swells and onshore flow will persist high risk of rip currents
at area beaches today with surf heights around 2-4 ft on
average. The risk will likely drop to moderate for at least
southeast GA beaches Monday.
&&
.FIRE WEATHER...
- Minrh Values Below 30 Percent Common Inland Se Ga This Period
- High Dispersions Inland Rest Of Today
- Patchy High Dispersions Possible Ne Fl Tuesday
High pressure will prevail through the upcoming week, with dry
weather continuing. Min RH values from the mid 20s to lower 30s
percent range the next few days inland areas through Tuesday. In
these areas, sustained winds will likely be below 15 mph. Closer to
the coast, RH values will be higher but easterly winds may be breezy
at times up to 15 mph due to the Atlantic sea breeze.
FOG POTENTIAL AND OTHER REMARKS: Patchy fog late tonight and early
Monday, and again early Tuesday morning.
