.DISCUSSION...


KEY MESSAGE 1...A period of well-above normal temperatures begins next week,
followed by a potential cold front towards the end of the forecast
period.

KEY MESSAGE 1 DESCRIPTION...

Other than some showers across the Alleghenies tonight and early
Saturday, a dry frontal passage is expected east of the
Appalachians.

Surface high pressure starts to move offshore on Monday. A
pressure gradient to the east brings a slight chance of rain in
the morning hours on Monday and Tuesday, primarily over the
Alleghenies. Upper-level ridging is expected to persist in the
region through midweek. This will allow for a significant
extended warming period to occur, allowing for the region to reach
potentially record highs by next Wednesday. Highs are currently
forecasted to reach the upper 80s for much of the forecast area next
Tuesday, with highs in the lower 90s currently forecasted for next
Wednesday. Ensemble guidance continues to be well aligned on the
progression of this warm-up, but the GFS remains somewhat on the low
end of the deterministic spectrum regarding the exact maximum
temperatures that could be reached.

Looking ahead, a broad area of low pressure could start to
develop over the Great Lakes and make its way over towards the East
Coast by late next week. This would bring a cold front through the
region in the Thursday-Friday timeframe, potentially bringing a
slight cooldown to the region.

&&

.AVIATION /07Z FRIDAY THROUGH TUESDAY/...

S winds around 10 kt this afternoon, shifting to N Saturday with
gusts up to 20 kt behind a frontal passage. Winds subside Sat
night.

Southwest winds will blow around 10 knots on Monday, with wind
gusts up to 20 knots possible. Winds should decrease throughout
the day on Tuesday. VFR conditions expected across terminals
during this period, as any rain chances will remain off to the
west.

&&

.MARINE...

SCA has been issued for Saturday for northerly winds behind a
frontal passage.

Small Craft Advisories are likely on Monday through Tuesday morning
as 15-20 knot winds blow from the south. Gusts up to 30 knots
possible on Monday, with stronger gusts towards the central
Chesapeake Bay. SCAs may still be needed on Tuesday morning
before winds gradually decrease to 5-10 knots south by Tuesday
night.

&&

.FIRE WEATHER...

Gradual warming and continued dry conditions are expected through
this afternoon as high pressure departs offshore. Winds will be
a touch stronger today out of the south, and could gust to
20-25 mph, particularly on the higher ridges. Conditions will
be dry once again, with min RH values in the 20s to the west of
the Blue Ridge, and upper 20s and 30s to the east of the Blue
Ridge.

Other than a small chance for a shower in the Alleghenies
tonight as a cold front moves through, no precipitation is
expected over the next several days. Gusty northerly winds will
develop behind the front Saturday morning, but may not overlap
as humidity values drop by afternoon. An SPS for elevated fire
danger may be needed.

Even warmer conditions are likely early next week as another area of
high pressure builds across the Mid Atlantic coast with minimal rain
chances. Expecting fuels to further dry out in this pattern,
particularly given the high amounts of solar insolation reaching
the ground over the past several days.
