.SYNOPSIS...
Unsettled weather will continue through the week with daily chances
for showers and thunderstorms. A potent cold front will cross the
area Thursday into Friday, bringing an increased threat for flooding
and severe thunderstorms. Rain chances diminish and cooler
temperatures arrive this weekend with high pressure nearing the
area.
.NEAR TERM /THROUGH TONIGHT/...
Early morning convection and showers have continued to diminish
and moved further to the east. Some brief breaks in the clouds
coupled with light winds will likely allow for areas of patchy
fog with even some localized dense pockets occurring through
sunrise. A fairly quiet start to the day with just a few showers
moving in from the west. By the afternoon, some convection may
pop up around the area with overall coverage being pretty low.
Should any of these thunderstorms become strong, an isolated
severe thunderstorm is possible. The most likely hazard would be
damaging winds. Afternoon highs will be in the upper 70s to low
80s for most areas.
By tonight, a cluster of thunderstorms from the Ohio Valley will
approach our western areas. These storms should be diminishing as
they reach the area so severe chances are non-zero but fairly low.
This convection may actually help suppress further storms during the
day on Wednesday. Overnight lows will drop down into the 60s for
most locations.
.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
Early morning convection as a result of a decaying MCS on Wednesday
should begin to scoot further east of the area by just after
sunrise. A mix of sun and clouds should progress throughout the day
with some afternoon convection potentially forming, especially the
further south across central VA. Given the breaks in the clouds
amplifying the instability, any storms that do form have the
potential to become strong to severe. The main hazards would be
damaging winds and large hail. The overall probabilities looks
fairly low given the latest guidance but we will continue to monitor
this event. Highs on Wednesday will soar into the mid to upper 80s
across many lower elevation locations, with even a few areas
potentially hitting 90 degrees. The mountains will be in the mid to
upper 70s for the afternoon.
Clouds will increase Wednesday night ahead of a potent cold front
poised to cross the Mid-Atlantic on Thursday. Shower chances begin
to increase across the southwest late Wednesday night and by early
Thursday morning most areas will increase the chances of
precipitation greatly. Instability parameters increase by
Thursday afternoon just ahead of the cold front, this will allow
for the potential for strong to severe thunderstorms to
develop. Steep low-level lapse rates support large hail along
with damaging winds with any of these storms. Overall severe
coverage may be limited with the enhanced cloud coverage prior
to initiation but it will be worth monitoring. Additionally,
given the antecedent conditions, cannot rule out isolated
instances of flooding (especially along and west of the Blue
Ridge) Wednesday and Thursday afternoon/evening. Afternoon highs
will climb into the upper 70s to low 80s for most areas.
Northwest flow kicks in behind the cold front Thursday night and
will bring lows in the 40s along the Allegheny Front with 50s
further east.
.LONG TERM /FRIDAY THROUGH MONDAY/...
By Friday morning, we should be situated within a noticeably
cooler and less humid post-cold frontal environment.
Temperatures should only climb into the 60s to lower 70s Friday,
with dewpoints holding in the upper 40s to lower 50s. The day
should start out dry, but chances for showers will be on the
increase during the afternoon as a shortwave trough rapidly
approaches from the Midwest/Ohio Valley. This shortwave trough
will pass to our east Saturday morning. However, longwave
troughing over the Eastern US will be maintained by another
shortwave approaching from the Great Lakes/Ohio Valley. We`ll
start the day off within the zone of subsidence behind the
departing shortwave, which should lead to a mostly sunny start
to the day. Clouds should be on the increase through the
afternoon though as ascent ahead of the next shortwave starts to
approach from the west. Depending on the timing/progression of
the next shortwave, some showers may be possible Saturday
afternoon, especially to the west of the Blue Ridge. Chances for
showers will increase across the entire area Saturday night
into Sunday as the main upper trough axis moves overhead. High
temperatures this weekend are expected to be in the upper 60s to
near 70, with lows in the 40s to lower 50s.
Spread in model guidance starts to increase by Monday, but the
general trend will be for heights to rise aloft as upper troughing
departs off to our east. This will allow high pressure to build
toward the area at the surface, and a warming trend to ensue. High
temperatures are forecast to reach into the low-mid 70s on
Monday.
