Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
241 PM EDT Tue Jul 30 2019
.SYNOPSIS...
A cold front and upper level trough will approach the region
from the west today and reach the area Wednesday. The front
will then stall in our vicinity for several days.
&&
.NEAR TERM /THROUGH TONIGHT/...
A cold front and upper level trough will continue approaching
the region from the west through the remainder of today and
tonight. Southerly flow has increased out ahead of the system as
surface high pressure shifted offshore. Temperatures have soared
into the low to mid 90s, and even some upper 90s along the I-95
corridor. Dew points are generally in the mid to upper 60s, but
have noted some lower dew point air beginning to mix out across
northern and central Virginia where dew point readings have
dropped to near 60F. MLCAPE of roughly 1000-1500 J/KG has
developed near/west of the Blue Ridge and across
central/northern Maryland, with lesser amounts (500 J/KG) where
dew points have lowered. Have seen robust shower/thunderstorm
development across the higher terrain with some slow eastward
progression early this afternoon. Expect this general trend to
continue for the next several hours and this is captured well
by various CAMs. Some isolated severe activity is possible with
gusty and locally damaging winds the main threat. Localized
heavy rain is also expected, but overall flood threat should
remain low given recent dry weather. As the convection moves
eastward, it is expected to generally weaken as it moves east of
the Blue Ridge and especially towards the I-95 corridor as it
moves into less unstable air and an area of weaker forcing. That
being said, some isolated activity remains possible there into
the evening, and a few isolated popup showers/thunderstorms are
also possible along any sea-breeze boundaries.
Most of the shower/thunderstorm activity will wane during the
evening hours but some isolated showers may linger through the
night as forcing from the trough remains. Lows generally in the
high 60s and 70s.
&&
.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
The surface front will move closer on Wednesday with the upper
trough passing overhead. A very warm and humid day is expected,
although highs will be lower than today, generally in the 80s to
around 90F. Expecting MLCAPE values of up to about 1500 J/KG to
develop again, and with effective wind shear values of around
25 knots, some isolated severe activity is possible again. The
coverage of showers/thunderstorms will likely be greater than
today and across the entire region given the closer proximity of
the front/trough. An isolated flooding incident is also
possible. Convection will again wane overnight. Lows in the 60s
to low 70s.
The front will then stall near the area on Thursday and
therefore the region will continue to see chances for scattered
showers/thunderstorms. Highs generally in the mid to upper 80s.
Lows Thursday night in the 60s to low 70s.
&&
.LONG TERM /FRIDAY THROUGH TUESDAY/...
On Friday a mid to upper level trough will be embedded over the
eastern CONUS as a surface front remain stalled over our area
through the weekend. Location of the frontal boundary will determine
local impacts through Monday, but for now it seems that each day in
the long term forecast we could see some kind of shower/
thunderstorm activity.
A mid-level shortwave aloft will move across our region on Friday
and this will enhance the development of showers and thunderstorms
throughout our region. On Saturday the scenario is similar to Friday
but without any forcing aloft, therefore showers and thunderstorms
will be mostly enhanced by diurnal heating.
On Sunday a weak surface boundary will be approaching from the north
as the stalled boundary remains south of our area. Showers and
thunderstorms are still possible mainly along/near the boundaries.
At the same time a high pressure will try to build behind this weak
boundary into our region on Sunday night into Monday. Therefore the
highest chance for precipitation will be towards the southeastern
portion of our CWA on Sunday night.
On Monday/Tuesday there is some discrepancy on the guidance. Some
guidance have a high pressure building into our region from the
north while mid-level shortwave energy moves aloft, as the stalled
front lifts as a warm front on Tuesday. This could allow for
additional afternoon/evening shower and thunderstorm development.
There is also a drier scenario where the front moves away from us as
weak high pressure builds into our region from the north.
&&
.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
Mainly VFR is expected through at least Thursday night although
brief periods of sub-VFR conditions are likely. The main
concern through this evening is scattered showers/thunderstorms
with CHO/MRB having the highest risk. Some isolated
showers/thunderstorms are also possible at other terminals but
the risk is lower. After midnight, locations which receive rain
later today may see patchy fog. After that, more scattered
showers and thunderstorms are expected Wednesday
afternoon/evening and again Thursday afternoon/evening, with
patchy fog possible wherever it rains the following early
morning.
Periods of sub-VFR conditions are expected especially with the
shower and thunderstorm activity over our area while a boundary
stalls near our area Friday into Sunday.
&&
.MARINE...
Sub-SCA winds at present but a re-strengthening is expected
later this afternoon and through much of tonight. Winds will
lessen on Wednesday as a front moves into the region and then
stalls through Thursday, resulting in lighter and more variable
wind speeds. Isolated thunderstorms could produce gusty winds
this afternoon, but much more likely to be a concern Wednesday
and Thursday, mainly during the afternoon and evening hours and
Special Marine Warnings may become necessary.
Showers and thunderstorms are possible in the afternoon/evening
hours over the waters between Friday and Sunday. Periods of SCA
conditions are possible each day as well.
&&
.TIDES/COASTAL FLOODING...
Southerly flow will continue into Wednesday before a front
moves into the region and winds become more variable. The
consistent southerly flow may cause water levels to touch minor
flood stage, but uncertain at this time. Will continue to
monitor.
