AREA FORECAST DISCUSSION
National Weather Service Wakefield VA
854 PM EDT Fri Jun 14 2024

.SYNOPSIS...
A cold front will push through the region tonight with a few
showers and storms possible. Dry with seasonable temperatures
over the weekend, followed by a very warm to hot and mainly dry
pattern next week.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
As of 220 PM EDT Friday...

Key Messages:

- A few showers and storms will be possible this evening and
  tonight.

A cold front will gradually approach late this afternoon and
then crosses the area this evening into the overnight hours.
CAMS show scattered showers and storms developing ahead of and
with the front as it passes with the greatest coverage expected
to be N-NE of Richmond over to the Eastern Shore. Cannot rule
out an isolated strong to severe storm later this evening and
tonight from Caroline County and the Northern Neck across to the
lower MD Eastern Shore where SPC has us highlighted for a MRGL
risk of severe. Isolated damaging wind gusts will be the
primary threat. Any lingering showers/storms near the coast
should move offshore after midnight. Overnight low temps range
from the mid 60s to low 70s.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/...
As of 220 PM EDT Friday...

Key Messages:

- Dry weather and lower temperatures (seasonable) return for
  Saturday into Sunday.

Cooler on Saturday with pleasant/tolerable humidity values
behind the front. Highs rise into the mid to upper 80s but dew
points mix out into the 50s to low 60s during the afternoon.
A mostly sunny sky will prevail with northerly winds continuing
through the afternoon. Could be a bit breezy, especially near
the coast in the morning. Continued dry and pleasant Saturday
night with lows dropping into the upper 50s to low 60s.

Surface high pressure to the north will move offshore on Sunday as
an upper ridge builds NE. High temps will be a degree or two above
what we will see on Saturday with highs in the upper 80s inland with
low to mid 80s near the coast. Dew points remain comfortable in the
upper 50s to low 60s. Low temps Sunday night in the low/mid 60s
inland with upper 60s likely for coastal locations.

For Monday, a 595dm upper ridge centers itself over the mid-
Atlantic region while sfc high pressure offshore brings SW flow
to the area. This will allow for temperatures to rise above
normal with continued dry conditions. Highs will be in low 90s
inland with 80s along the coast.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
As of 220 PM EDT Friday...

Key Messages:

- Hot and dry weather returns next week, likely persisting through
  the end of the forecast period.

Models continue to depict an upper level ridge building across
the eastern 1/3 of the CONUS next week. Global models have come
into decent agreement showing the center of the upper ridge
orienting just N and NW of the local area by the middle of next
week. The ECMWF continues to be the most bullish with upper
heights but the GFS/GEM and their ensembles generally agree that
a period of hot temperatures will occur across the area next
week. With the core of the upper ridge displaced to the N, will
maintain some degree of onshore flow across the area. Highs
should be into the low-mid 90s well inland, but will tend to
stay in the upper 80s to lower 90s closer to the coast. The
continental origin of the ridge will likely mitigate heat
indices. The current forecast has heat indices through midweek
right around the actual air temperatures, generally in the low
to mid 90s. An inverted upper trough moves westward underneath
the upper ridge late week which could trigger a few storms over
our southern CWA. Overnight lows slowly creep up through the
week and range from the upper 60s to lower 70s.

&&

.AVIATION /01Z SATURDAY THROUGH WEDNESDAY/...
As of 745 PM EDT Friday...

A weak front will be advancing southward across the area through
this evening into the early overnight hours. This front will
touch off isolated to widely scattered showers and storms,
especially from just north of KRIC over to KSBY from now through
~06z. Included VCTS at SBY where confidence is highest.
Primarily VFR CIGs at all sites, but cannot rule out a brief
period of MVFR (mainly at SBY, ORF, PHF) after 06z until ~12z as
hinted at by a few high-res models. Overall confidence in sub-
VFR CIGs is low. Mainly SKC skies/VFR conditions are then
expected through the remainder of the forecast period. Winds
will be light from the S-SE through this evening before the
frontal passage causes winds to shift around out of the N early
Saturday morning.

Outlook: Winds will average 10 kt or less with VFR conditions
and mostly clear skies Sunday into early next week as high
pressure gradually shifts off the coast.

.MARINE...
-- Changed Discussion --
As of 855 PM EDT Friday...

Key Messages:

- A cold front will cross the waters tonight. Northerly winds
  behind the front are expected to gust to around 20 kt (some
  brief gusts close to 25 kt are possible on the Bay) for a few
  hours Saturday morning.

- Sub-advisory conditions are expected through the remainder of the
  weekend into early next week.

There was a brief jump in winds this evening over the lower Bay
to around 15 to 20 kt, but winds are slowly decreasing and will
remain around 10 to 15 kt ahead of the cold front. The cold
front is forecast to cross the waters early Saturday morning,
allowing winds to turn northerly. There will be a brief surge
behind this front with the strongest of the winds expected to
occur from between sunrise Saturday through early afternoon with
gusts to around 20 kt for a few hours (a few gusts to near 25
kt are possible based on some of the high res guidance.

Sub- SCA conditions are expected Sat aftn- Sun with NE to E
winds around 10 kt as high pressure builds southward into the
Mid-Atlantic states. Southwest winds late Sunday and Sunday
night could approach 15 kt as the pressure gradient tightens
with the high remaining to our north. Winds remain S-SE at 10 -
15 kt for the early part of next week with the ridge of high
pressure anchored in place.

Seas generally 2-3 ft over the ocean with 1-3 ft waves on the
bay through the period, although seas will briefly build to 4 ft
by mid to late Saturday morning behind the cold front.
