Synopsis
A weak cold front will drop south of the region early this
morning, then return back north of the area on Tuesday,
followed by a big warm up for the remainder of the week.

Near term until 6 pm this evening
As of 415 am edt Monday...

early this morning, a weak cold front was dropping down acrs
srn va with sctd showers finally about to exit off the lower md
ern shore. Otherwise, it was partly to mostly cloudy over the
region with temps ranging from the upper 60s to mid 70s.

The front will drop farther south of the area during today, with
weak high pressure providing nne winds and not as warm temps.

Mainly just a slight to sml chance for late aftn early evening
showers tstms. Highs will range thru the 80s to near 90, cooler
near the water.

Short term 6 pm this evening through Wednesday night
As of 430 am edt Monday...

the front will lift back north acrs the area as a warm front
tonight thru Tue morning. Upper ridging will build from the
gulf coast states nwrd toward the oh valley. That boundary could
help produce isolated to sctd showers or tstms, mainly acrs nrn
portions of the region. Lows tonight ranging thru the 60s.

The warm front will lift well nne of the area Tue aftn, but there
still could be slight to sml chance for diurnally-driven showers
or tstms over the ERN third of the region into the early evening.

Warmer and moderately humid on Tue under a partly sunny sky.

Highs will range from the upper 70s to mid 80s over the lower md
and va ERN shore, to the upper 80s to lower 90s elsewhere.

Mostly clear and mild Tue night with lows in the upper 60s to
lower 70s.

Upper ridging slides eastward and nwrd into the region for wed,
resulting in even warmer temps. Under a partly to mostly sunny
sky, highs will range from 85-90 over the lower md and va ern
shore, to the lower to mid 90s elsewhere. Later Wed aftn into
wed night, isolated to sctd showers tstms will be possible over
the NRN third of the cwa.

Long term Thursday through Sunday
As of 430 am edt Monday...

by Thursday, the upper level ridge axis begins to break
down push east of the local area as a more potent shortwave
develops and moves across the midwest and great lakes. Thursday
will likely be another very hot day with temperatures making it
up into the mid 90s across much of the area. Shower and
thunderstorm chances will be on the increase as the shortwave
and associated cold front approach and cross the region late
Thursday into early Friday. This boundary then stalls lingers
near to just south of the region into the weekend bringing the
potential for more unsettled conditions. Temperatures cool down
slightly Friday into the weekend, but are still expected to
remain above average as highs in the mid to upper 80s are
anticipated.

Aviation 09z Monday through Friday
As of 300 am edt Monday...

a cold front was dropping down acrs SRN va early this morning,
with sctd showers finally about to exit off the lower md ern
shore. Otherwise, mainlyVFR conditions were prevailing at the
taf sites, with just isolated sct stratus at sby. SW winds
around 5 kt were shifting to the nw-ne behind the front.

The front will drop south of the entire area early this morning,
with nne winds 5-10 kt during the remainder of the day, then
light E becoming SE this evening into Tue morning.VFR conditions
will prevail thru the period, with only isolated to sctd
convection possible at ric phf orf ecg late this aftn into early
this evening.

Outlook:
mainlyVFR conditions will continue Tue thru wed, with isolated
to sctd pcpn possible mainly at sby and ric.

Marine
As of 330 am edt Monday...

outside of convection, a rather quiet marine forecast for the
next several days. A weak frontal boundary is pushing south
through the waters early this morning and will stall wash out s
of the local area this aftn evening. A N wind will avg around
10 kt through midday with some gusts to ~15 kt. The winds become
ne then E during the aftn at 5-10 kt, and continue to veer to
the sse tonight into Tue morning at ~10 kt. Waves 1 to 2 ft in
the bay and seas 2-3 ft offshore.

S winds 10-15 knots are expected by Tuesday afternoon as high
pressure aloft remains anchored over northern gulf coast and the
frontal boundary lifts back N of the area as a weak warm front. Waves
in the bay will generally run 1-2 ft while seas offshore will
stay in the 2-4 ft range through mid week. There are some model
discrepancies regarding the winds on wed, the NAM tries to push
the front back S into the local waters (which would lead to ne
winds). The other models are in a general agreement that the
front will be weak and mostly stay N of the local area. Will
follow the consensus for now as it also retains continuity with
the forecast. This will have mostly SW winds Wed into Thu and
sub-sca conditions.

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.
