Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
909 PM EDT Tue Jul 12 2022
.SYNOPSIS...
A cold front will drift into the area tonight before stalling
nearby through the remainder of the work week. High pressure
will build in from the west by Friday and into portions of the
weekend.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
Severe threat should be winding down quickly as collective
outflow is pushing south of the area with surface based
stability increasing. However, the actual cold front remains
across western Pennsylvania into the Ohio Valley. Lift in the
mid levels and elevated instability are resulting in some
regeneration of storms on the cool side of the outflow. Due to
potential training, some localized flood/flash flood issues
could arise. Extended the Flood Watch to the west with an
earlier update since there were pockets of lower flash flood
guidance across this area. This is a short lived threat though,
as any lingering showers and storms should taper off between
midnight and 2 AM. Overnight lows will be in the 60s to lower
70s.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH THURSDAY NIGHT/...
A cold front will move to the south of our CWA Wednesday. Its
close proximity to our southern waters, southern MD and eastern
VA could pose a threat for additional showers and a thunderstorm
or two. High temperatures should reach the 90 degree mark, but
with less humidity as winds turn westerly. Nighttime conditions
stay mild with lows slightly above climatology.
The front will remain just off to the south and east Thursday
into Thursday night. A slight chance for showers and
thunderstorms exists over areas of central Virginia into the
Shenandoah Valley. Otherwise, a mix of clouds and sun are in the
forecast. Highs will be a few degrees cooler than the previous
day. Winds northwest will ensure a bit less humidity for areas
farther removed from the stalled front. Seasonably mild
conditions continue overnight.
&&
.LONG TERM /FRIDAY THROUGH TUESDAY/...
A frontal boundary is expected to linger to the south of the LWX CWA
area into this weekend. Locally, showers and thunderstorms are
possible with any given shortwaves that cross the area throughout
the long term period. If the front were to stall further north then
precipitation totals will likely increase but the likelihood for
this to occur at this time is lower. As the front shifts further
south late in the weekend, a cold front will approach the area by
Monday and may bring the chance for some strong to severe
thunderstorms for the afternoon and evening hours. An isolated flood
threat is also possible with PW anomalies 1 to 1.5 SD above normal.
Warm, moist air will continue throughout the period as no real
airmass changes occur through early next week before the cold front
passage.
&&
.AVIATION /01Z WEDNESDAY THROUGH SUNDAY/...
Heaviest storms are south of most of the TAF sites with the
exception of CHO, which could be impacted by storms through 10
or 11 PM. However, there have been plenty of lightning strikes
in the trailing anvil, but this threat should depart by 10 PM or
so in the metro areas. Cold front and drier is is lagging, so
some fog could form later tonight, with the greatest chance at
MRB.
South-southwesterly flow shifts to westerly on Wednesday as a
front sags to the south. Winds will turn more northwest Thursday.
Mainly VFR conditions are expected both days although a few
lingering storms are possible around KCHO.
A few showers and thunderstorms will be possible through the long
term period each afternoon and evening with the southern terminals
having the higher likelihood for this. CIGs and Vis may be
affected during this time frame. Winds are expected to remain
calm into the weekend.
&&
.MARINE...
Threat for thunderstorms with strong to damaging winds will
remain through late evening across the waters bordering
southern Maryland. Otherwise winds should be fairly light
through the night. Light winds are expected Wednesday and
Thursday with the flow turning more west to northwesterly. A few
isolated storms may fire over the southern waters given a
nearby frontal boundary.
No marine hazards are expected for the weekend other than if a stray
thunderstorm were to make it to the waters.
&&
.TIDES/COASTAL FLOODING...
A south to southwesterly flow will lead to elevated anomalies
over the next few days. Some coastal sites may reach minor flood
stage over the next three to four tide cycles.
&&
