High pressure moves further offshore today. A cold front tracks into
the region Friday, with increasing shower and thunderstorm chances.
Secondary high pressure builds back in for the weekend with lower
humidity and slightly cooler temperatures. Hot and humid conditions
return next week as a strong upper ridge impacts the area.

High pressure will continue to slide further offshore later
today. Some scattered cumulus clouds will continue to form early
this afternoon and continue to build throughout the remainder
of the day. Afternoon highs will be in the mid to upper 80s for
most areas with even a few sites reaching 90 degrees. The high
terrain will likely top out in the upper 70s to low 80s.

With some subtle lift in the flow, cannot completely rule
out an isolated shower for the afternoon and evening hours and just
after sunset. While these showers will likely be fairly short-lived,
there is a non-zero chance for an isolated rumble of thunder given
the convective parameters in place. Showers and thunder chances
should fall off just after sunset with overnight lows dropping into
the 60s.

Friday morning, conditions should be mostly dry with clouds
increasing from the northwest as a result of an approaching cold
front moving in from the Great Lakes region. Another above normal
temperature day is expected, with highs in the low 90s across the
lower elevations and mid to upper 70s for the mountains. The cold
front will likely become more negatively tilted as it approaches
areas along and east of the Blue Ridge which may enhance coverage
and intensity of any showers and thunderstorms that spawn. For now,
expecting isolated to scattered thunderstorms to develop Friday
afternoon and evening just ahead of the frontal passage. With
increased CAPE, slightly steep low-level lapse rates, and increased
flow aloft, a few of theses storms may become strong to severe. The
area of best chances for this looks to be across north-central to
northeast MD. The main hazards for these storms will likely be
damaging winds, with increasing DCAPE through the afternoon. Cannot
rule out some hail with these storms as well. Most convection likely
moves east of the area after midnight Friday. Overnight lows will
fall into the low to mid 50s across the mountains and slightly
warmer into the low to mid 60s further east across the lower

Secondary high pressure will build in for the weekend, with
decreasing humidity and slightly cooler temperatures. Highs will
generally be in the low to mid 80s both days, with winds remaining
light. Overnight lows Saturday night will be in the 50s for most
areas, with gradual humidity increase Sunday night with lows in the
low 60s for most areas.

Upper level ridging sets up over the eastern half of
CONUS for the entirety of the long term period. Sunday will be the
coolest day of the long term period with high temperatures in the
80s for most. Those at higher elevations will stay in the mid to
upper 70s. With high pressure at the surface, dry conditions are
expected areawide. Dry conditions are expected overnight Sunday into
Monday with low temperatures 60s for most.

As we head into the workweek and the ridge settles overhead, above
average temperatures will be the main story. While there is a bit of
model discrepancy on exact high temperature forecasts, models agree
on above average temperatures each day. High temperatures each day
will be in the 90s with only those at highest elevations staying in
the 80s. With dew points in the upper 60s, heat indices will rise
into the upper 90s to even exceeding low 100s possible. Overnight
low temperatures will cool into the 60s to low 70s each night with
the metro areas staying in the upper 70s.
