1056 pm edt Sat aug 18 2018

Synopsis
High pressure will remain well off the southeast u.S. Coast
through tonight. A cold front will approach from the northwest
tonight, then drops across the area late tonight into Monday
morning. The front will stall over north carolina Monday into
Monday night, before lifting back north as a warm front on
Tuesday. A cold front crosses the area on Wednesday.

Near term through Sunday
As of 1045 pm edt Saturday...

convection this evening is shifting more to the south over NE nc
and should persist for several more hours, but the impacts are
mainly just brief heavy rain with wind gust near 20 - 25 mph.

This convection should diminish as shortwave energy slides off
the coast. Meanwhile, the atmosphere remains very moisture
laden this evening as the surface front remains near the mason
dixon line. So have kept a mention of a low chance for a shower
across northern portions of the CWA due to the amount of
moisture and the introduction of the front into the area toward
morning. Lastly, have tweaked overnight lows down across much of
va as the rain had caused temps to drop more quickly.

Prev discussion...

shortwave trough approaching from the west beginning to trigger
showers tstms across southern portions of the region this
afternoon. Airmass remains very humid and moderately unstable,
so a few storms may produce strong wind gusts, along with
frequent lightning and heavy rainfall. Limiting factors for
severe weather are moderate instability and weak shear. Best
thunderstorm chances will be across the southern half of the
area, where best heating has occurred thus far today. Elsewhere,
have maintained high chance likely pops, but with a slight
chance of tstms.

Most widespread shower TSTM activity will continue east toward
the coast through 06z, before weakening moving offshore.

Lingering showers, albeit with limited coverage, will remain
possible in moist airmass through the night. Temps will only
fall into the lower and mid 70s again.

Another threat for showers tstms will develop on Sunday, as
surface cold front gradually drops into the region from the nw.

Coverage will again be greatest across the southern half of the
area, with NW sections probably drying out during the afternoon.

Skies will be partly to mostly cloudy, with MAX temps lower to
mid 80s in our DELMARVA region, and mid to upper 80s elsewhere,
with continued high dewpts.

Short term Sunday night through Tuesday
As of 315 pm edt Saturday...

cold front will stall just south of the area by Monday, with
lingering chances for showers isolated tstms southern swrn
areas Sunday night through Monday. Low temps Sunday night 70-75.

Surface winds turn E NE for much of the area on Monday, which
will limit temperature rise in many areas. On the lower md
eastern shore, temps could remain in the upper 70s, if the ne
flow is strong enough. Have currently forecast around 80.

Otherwise, expect MAX temps to mainly be in the lower to mid 80s
across the north, and mid to upper 80s southern portions.

Cold front begins to lift back northward as a warm front Monday
night Tuesday, as stronger surface low organizes in the midwest,
and begins moving newd into sern canada by Tuesday evening.

Scattered showers tstms again expected as the front lifts
northward. Although warmer than Monday, clouds and precipitation
should keep temperatures in the middle to upper 80s across the
region.

Long term Tuesday night through Saturday
As of 315 pm edt Saturday...

a cold front will approach the CWA Wednesday morning, quickly moving
east through the region Wednesday afternoon. Chance pops were drawn
in for the potential of pre-frontal showers tstms... However, a
morning or mid-day FROPA will not allow convection to take advantage
of diurnal heating. The 12z GFS is most impressed with rain chances,
followed by a modest euro and canadian solution. Drier weather
settles in Thursday, with only slight chance pops remaining across
nc. 1024 mb high moves east over the mid-atlantic Thu pm thru sun
next weekend, keeping a majority of the area dry. The only portion
of our area with marginal rain chances will be in nc, where ridging
will be weaker. Most outdoor plans should fare well late next week
into the weekend.

Temperatures will remain warm Wednesday but cool down noticably,
starting Thursday, into the low-middle 80s. Dew points will also
drop into the low-middle 60s, helping to make conditions feel quite
comfortable for mid august. Overnight lows will range from the low-
mid 60s inland to near 70 degf along the coast.

Aviation 03z Sunday through Thursday
As of 745 pm edt Saturday...

mostlyVFR conditions across the region and at the TAF sites
except where strong precipitation is occurring. A wide area of
showers and thunderstorms is occurring from west of richmond to
ne nc and across the marine waters. Heavy rain and wind gusts to
30-35 kt are the most significant hazards with the strongest
storms. A cold front lies well west of the forecast region.

Warm humid air east of the front will continue to produce widely
scattered showers and or thunderstorms through the overnight.

MVFR ifr conditions may occur with any precipitation but
overall expect mostlyVFR conditions.

There is a chance for some patchy areas of fog especially in
areas with good rainfall but confidence is not high enough to
add to TAF locations at this time. Guidance does show a brief
period of ifr ceilings for ric in the morning so decided to go
with 400 ft ceilings in the morning between 10-14z.

Outlook... A cold front will move into the region on sun, with
the chance of showers tstms continuing, especially from kric
southward. The front drops south of the region mon, with a
chance of showers tstms mainly across SRN va and NE nc.

Unsettled conditions potentially continue into tue, as the front
lifts back northward as a warm front. A stronger cold front
moves across the area on Wednesday.

Marine
As of 315 pm edt Saturday...

no headlines necessary with this forecast package. Sfc high pressure
resides offshore tonight as a trough of low pressure remains over
the mid atlantic. SW winds up to ~15 kt over the bay and 15-20 kt
over coastal wtrs with 2-3 ft seas. A cold front then drops into the
area during the day Sun leading to unsettled conditions with sw
winds shifting to N NE by Sun night mon. Sub-sca conditions expected
to continue into early next week.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
