954 pm edt Thu aug 22 2019

Synopsis
A cold front will cross the area late tonight into Friday, then
move into the carolinas over the weekend. Canadian high
pressure will build north of the region over the weekend as low
pressure forms off the southeast coast and slides by near or
east of the area Monday into Tuesday.

Near term until 6 am Friday morning
There is currently ongoing convection over portions of
maryland... Mainly near the baltimore metro area and over the
northern portion of the chesapeake bay. This main area will
continue to move east-southeast away from us with some
lingering showers thunderstorms continuing over the next hours.

A cold front sits to our north and is expected to continue to
move southeastward and into our cwa. This will continue the
chance of scattered showers overnight across portions of the
region. Lows will range through the 60s to low 70s.

Short term 6 am Friday morning through Saturday night
The front will continue its track southward through the day
Friday and likely be nearing the nc va border by the evening.

However strong southwest flow will remain aloft with upper
level energy traversing the region, so rain showers are likely,
especially across central western va, into the mid afternoon
hours. A few thunderstorms with locally heavy rain are possible
as well. Otherwise, mostly cloudy skies and cooler temperatures
are expected. Highs from the upper 70s to around 80f.

Cool and dry air will continue its progression southward into
the region Friday night. Lows will drop into the upper 50s to
mid 60s.

A ridge of high pressure will be in control on Saturday with
mostly sunny skies and highs in the upper 70s to low 80s. Lows
Saturday night will once again be in the upper 50s to mid 60s.

Long term Sunday through Thursday
High pressure will be set up across the northeast on Sunday,
resulting in relatively dry and cooler than average temperatures.

Highs will only reach the upper 70s low 80s. With a departing upper
low, and onshore low-level flow, can't rule out a shower or some
drizzle on Sunday.

On Monday and Tuesday, the forecast is a bit murky at this point.

Ridging along the eastern seaboard will lead to the formation of a
stationary front along the east coast. Meanwhile, a weak wave of low
pressure will be moving out of the caribbean and up the southeastern
coast Sunday into Monday, resulting in the formation of a surface
low pressure system somewhere along the southeast coast. This is
actually the disturbance that the national hurricane center has
outlooked for potential development along the east coast. Then, it
is all a matter of where this low tracks, and what form the low
takes. The GFS brings the low relatively close the delmarva
peninsula, meaning more rain for our eastern zones. Meanwhile, the
euro keeps the low farther offshore, but still brings a chance for
showers to eastern areas due to onshore surface flow. To sum this
up, there is a lot of uncertainty in this portion of the forecast
until we start to see the pieces fall into place, which just hasn't
happened yet. But depending on how this coastal low develops (still
some uncertainty if it will become tropical subtropical in nature),
and which direction it moves, the forecast could change drastically
in the coming days. For now, will keep chance pops in the forecast,
with a slight potential for some embedded thunderstorms. Monday and
Tuesday should remain near to slightly below average in terms of
temperatures, with highs in the low 80s.

On Wednesday, showers and thunderstorm chances increase due to an
approaching cold front. This should also push the coastal low off to
the north and east (if it does indeed track up our way). Regardless,
yet another afternoon with showers and storms across the region.

Aviation 02z Friday through Tuesday
MainlyVFR conditions are expected through tonight. Isolated to
scattered showers and thunderstorms may cause restrictions the
next hours. A cold front will then cross the area late tonight
into early Friday with additional chances for showers and
possibly some MVFR stratus. High pressure builds for the weekend
withVFR returning.

Vfr conditions expected on Monday. A passing shower or light drizzle
may pass over a terminal, primarily in the vicinity of bwi mtn dca,
but shouldn't cause any real issues.

Monday is a bit more tricky, with the potential for a coastal low
riding up the east coast. For now, thinking it is more likely that
we see primarilyVFR conditions. However, if some of the guidance is
correct, we could see a prolonged period of sub-vfr conditions late
Monday into Tuesday. For now, leaning with the drier side of
guidance.

Marine
Gusty showers and thunderstorms are moving across portions of
the waters this evening -some with smws at this moment-.

Otherwise sub-sca conditions are expected through tonight and
Friday. Winds will increase out of the north late Friday and
Friday night and SCA conditions are possible late Friday and
Saturday.

A stiff easterly to northeasterly flow along the chesapeake bay will
bring us close to SCA criteria on both Sunday and Monday afternoon.

Monday is a little more uncertain, as a coastal low may pass nearby,
which could result in stronger winds. Right now, keeping things
close to SCA criteria.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
