Synopsis
Warm, high pressure both at the surface and aloft will remain
overhead through the weekend and into next week. Hurricane maria
is expected to remain over the atlantic and well to our
southeast through at least early next week.

Near term through Friday
Tropical storm jose remains off the coast of new england. It is
expected to remain there and weaken over the next few days.

High pressure ridge extends along the appalachians with its
influence over the eastern u.S. Lows tonight in the 50s and 60s.

Winds will be light.

Short term Friday night through Saturday night
High pressure ridge at the surface will remain more or less
stationary over the appalachians through Saturday night. Aloft,
ridge of high pressure centered over the midwest will continue
to extend its influence across our region, while jose will
continue to meander over the northwest atlantic near new
england. The end result will be continued warm and dry weather,
with the only real weather concern being extent and coverage of
patchy fog each morning. Highs will be well into the 80s Friday
and Saturday with lows in the 50s and 60s. Winds will be light.

Long term Sunday through Thursday
High pressure will control the weather pattern Sunday... Bringing
more dry and warm conditions.

The remnants of jose may push closer toward the east coast Monday
and Tuesday... But latest guidance suggests that this remains far
enough out to sea so that it will have little impact on our weather.

The vast majority of the GEFS members keep it out to sea.

Therefore... The most likely scenario is that high pressure will
continue to control the weather pattern... Bringing more dry
conditions along with above normal temperatures.

Hurricane maria may approach the east coast of the united states
during the middle portion of next week. Latest guidance suggests
that there is a better chance for this system to remain
offshore. Please consult the national hurricane center for the
latest information regarding the forecast for hurricane maria.

Aviation 01z Friday through Tuesday
Main concern through the next several days is patchy late night
fog, mainly at mrb and cho. Vis could drop briefly to ifr at
either or both sites each of the next three mornings. An MVFR
restriction is not out of the question at the other terminals
(except dca). Otherwise,VFR with light winds should prevail
through Saturday night thanks to high pressure.

More of the same into next week. High pressure will control the
weather pattern Sunday through Tuesday. Areas of low clouds and
fog are possible during the overnight and early morning hours
each day.

Marine
High pressure will provide dry weather with sub-sca winds
through the weekend into early next week.

Global models show winds strengthening on Tue as pressure
gradient tightens as hurricane maria gets closer to the mid-atlc
coast middle of next week. For now, it appears small craft
advisories are possible.

Tides coastal flooding
Minor coastal flooding will continue along sensitive tidal shores
over the next several days.

Lwx watches warnings advisories
Dc... Coastal flood advisory until midnight edt tonight for dcz001.

Md... Coastal flood advisory until 11 am edt Friday for mdz014.

Coastal flood advisory until 6 am edt Friday for mdz017.

Va... Coastal flood advisory until midnight edt tonight for vaz054.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
