Synopsis
Unsettled conditions will continue through this evening as an
upper level trough crosses the local area from the west.

Conditions improve on Friday. Warmer temperatures and chance
for showers and thunderstorms will return over the weekend. A
cold front will approach from the west on memorial day.

Near term until 6 am Friday morning
Dry slot continuing to fill up W bkn CU and developing (sct)
tstms as an upper level trough enters the region... Steepening
lapse rates. Fa remains under marginal risk svr from spc... Main
threats from any stms will be gusty winds hail. Otherwise... Vrb
clouds partly sunny into this evening. For the
overnight... Becoming partly cloudy S W any lingering shras
waning... Mostly cloudy N W possible additional isold-sct shras.

Lows from the m50s W to l60s at the immediate coast.

Short term 6 am Friday morning through Sunday
Other than possible isold shras and vrb clouds far nne locations
early Fri as upper level low is slow to reach new england... Drying
out W deep layered wnw flow. Expecting a return of temperatures
back to or above normal W partly-mostly sunny conditions. Highs
mainly 80 to 85f... Except u70s at (most of) the beaches.

Weak ridge aloft nudges into the region from the wsw Fri night
into sat. Models in a bit better consensus W the arrival of
weak S W tracking into the fa by Sat afternoon. Combination of
daytime heating and that S W in wnw flow aloft will likely result
in at least sct convective development. Will have pops
increasing to 30-50% over most of the fa. SPC has outlooked
wrn central areas of fa slgt risk svr... Other areas marginal
svr. Otherwise... Partly cloudy Fri night- Sat morning... Then
becoming mostly cloudy Sat afternoon. Lows from the u50s NW to
the low 60s se. Highs Sat from the m-u70s- around 80f on the
eastern shore to the m-u80s inland.

Nearly zonal flow aloft remains Sat night into sun. Another S w
aloft expected to arrive during sun... Which again combined w
daytime heating likely results in sct convective development.

Lows Sat night ranging through the 60s. Partly sunny Sun w
highs mainly in the l-m80s (70s at the beaches).

Will highlight possible strong to severe tstms in hwo for the
weekend.

Long term Sunday night through Thursday
The somewhat unsettled weather will continue into Monday with the
baroclinic zone nearby and a strong upper jet just north of the
area. Expect additional showers and thunderstorms once again on
Monday in the cyclonic flow. It will be a warm day with highs in the
mid-upper 80s. The front will stall out over north carolina on
Tuesday and may allow for additional showers and storms Tuesday
across NE nc and south va. High pressure builds across the
region for Tue night-Thursday with dry and seasonable conditions
expected.

Aviation 20z Thursday through Tuesday
A line of showers and thunderstorms over the piedmont will move
eastward late this afternoon, affecting ric btwn 20-22z. The storms
may affect phf and orf after 21z, and sby around 22z. Some gusty
winds and small hail are possible with these storms, as well as
brief ifr conditions. Otherwise,VFR conditions should dominate as
the associated cold front passes through this evening allowing for
drying conditions under westerly flow.

Friday should be dry withVFR conditions, then sct showers and
storms return for Saturday into early next week as the pattern
remains somewhat unsettled.

Marine
Latest sfc analysis shows a broad area of low pres across the
mid atlc - oh valley with its main cold front already pushing
offshore. SW flow continues tonight behind the front, and still
looks to be enough of a gradient for 15-20 kt winds over most
waters... So headlines over the bay sound lwr james extend
through at least Fri morning. The SCA over the ocean is for seas
up to 5 ft out 20 nm. Weak high pres then builds in for late
fri Fri night leading to improving marine conditions. Sub-sca
conditions expected to continue into the weekend.

Tides coastal flooding
The continued onshore flow combined with high astro tides will
result in elevated water levels through Friday. The sse winds
continue to pile up the water across the middle ches bay so
based off the latest data, went ahead and extended the coastal
flood advisory for the bay side of the lower md eastern shore
for the next high tide cycle. Also issued coastal flood statements
for the va northern neck and atlantic coastal waters from oxb-cape
charles for levels approaching minor flood levels. See cfwakq
for more details.

Akq watches warnings advisories
Md... Coastal flood advisory until 4 pm edt this afternoon for
mdz021>023.

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.
