Synopsis
Very hot and humid conditions will continue over the region
through Sunday. A weakening cold front will gradually push
across the area late Sunday night through Monday and stall
across the carolinas through the middle of the upcoming week.

Temperatures will cool down to near normal levels Monday
through Thursday.

Near term through today
Latest analysis indicates a weak sfc lee trough lingering over
the mid- atlantic region from nj down ssw into the piedmont of
the carolinas. Energetic wnw flow prevails aloft. The initial
batch of strong to severe thunderstorms has now pushed off the
coast of the va ERN shore, with additional development
occurring across central NRN va to the md ERN shore. Damaging
wind gusts will be the primary threat through the early
overnight hours, though steepening mid-level lapse rates could
portend to some strong updrafts and the potential for some hail
across the NRN tier of the area, and frequent lighting is
expected with strong updrafts. Pops should generally be 30-50%
for scattered coverage for the NRN half of the area and AOB 20%
for most other areas overnight. Still very warm and humid for
areas that have not been "cooled" by rain. Lows most areas 75
to 80 f, slightly "cooler" across the north, especially in areas
the do receive rain.

Continued hot and humid with additional heat headlines now
issued for about the southern 2 3 of the CWA (along S of wal to
ric to lunenburg co. Line) where heat indices of 105 to 109 f
expected. Could potentially reach to 110+ along for NE nc but do
anticipate highs a little cooler than today so have held off on
this for now. Sunday remains a bit of a conditional convective
threat. Numerous convective boundaries are likely to be in
place, which would serve as a focusing mechanism for afternoon
and evening convection. However, uncertainty exists regarding
the extent and degree of cloudiness from convective debris which
hangs around into Sunday, thereby serving to dampen
destabilization. Models are still split on extent of cloudiness
through the early afternoon and have therefore elected to keep
pop in chance range (40-50%) for now, highest over the NE cwa.

Should convective debris clear out in a timely way on Sunday,
it's easy to visualize a scenario in which more widespread
convection occurs, given better lift lapse rates courtesy of the
approaching upper trough and the strong heating destabilization
that would result from quicker clearing. Once again, damaging
winds again the primary threat with storms on Sunday.

Short term tonight through Tuesday
Cold front slated to pass through while weakening late sun
night through mon. Will maintain high chc pops all zones sun
night, and favor highest pops Mon shifting south across SE va &
ne nc with 20% pops for the n. Slightly less humid Monday over
the NW cwa. Not quite as hot, with highs Mon 90 to 95 f. Front
stalls in nc tue, with mainly diurnal tstms possible again over
the s, 15-20% n. Seasonable highs upper 80s to lower 90s.

Long term Tuesday night through Saturday
High pressure moves off the coast Wed with any support for pcpn
across southern half of fa closer to a stalled frontal boundary.

Highs in the mid-upr 80s. Lows in the upr 60s-lwr 70s.

This boundary begins to drift north thurs resulting in slight
chc pops across the region. Highs in the upr 80s-lwr 90s. Lows
70-75.

Next boundary approaches from the north, then stalls across the
region Fri and sat. Chc pops each day though pcpn may tend to
concentrate across the southern half of fa Sat depending on how far
south the boundary actually gets. Highs Fri in the upr 80s- lwr 90s.

Lows in the upr 60s-mid 70s. Highs Sat in the mid-upr 80s.

Aviation 06z Sunday through Thursday
Vfr conditions at phf orf ecg... With MVFR ifr conds in shra tsra
at ric sby early this morning. Expect a return toVFR conditions
all terminals within the next few hours as convection wanes, and
expect a relative lull thereafter through early afternoon.

However, expect convection to re-develop ahead of an approaching
upper shortwave by mid-afternoon. In general, expect most
organized activity will be over the northern half of the area,
and have accounted for rain chances after 20z at ric sby.

However, confidence in areal coverage of storms remains quite
low ATTM and have elected to keep any vicinity thunder wording
out for now. Hoping cams will hone in a bit more on convective
chances for the 12z cycle, and will re-access at that time.

Outlook: convection slowly shifts south into south central va
and nc for Monday.VFR should dominate through this period, with
periods of periods of sub-vfr possible in heavier showers tsra.

A weak cold front pushes into the area for the mid week period.

Marine
No headlines expected as a SW wind AOB 15 kt prevails into the early
week. There could be a few gusts to 20 kts Sun aftn, but
duration is not expected to be long enough to justify a sca
headline. Seas 2 feet nearshore to 4 ft out near 20 nm. Sct
tstms possible in the afternoon eve hours.

The next frontal boundary crosses the area tues with a wind shift
into the e-ne. At this point, winds are expected to remain below sca
levels (aob 15 kts). Seas 2 to 4 ft.

Weak onshore flow continues for the rest of the week as a frontal
boundary stalls across the area. This will also act as a trigger for
sct late day convection as well.

Climate
Heat wave is expected to continue through Sunday. The 2nd half
of july is climatologically the hottest few weeks of the year,
so we still may not set any daily records at our main climate
sites. For reference, record highs for today and Sunday are
listed below:

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.
