Synopsis for the tidal potomac and md portion of the chesapeake bay.. High pressure will remain offshore today while a cold front slowly approaches from the northwest. The remnants of cindy will track along the front tonight, with the front finally pushing through on Saturday. A weak secondary front will cross Sunday before high pressure returns early next week. Small craft advisory conditions are possible Sunday.

Synopsis
High pressure remains centered just offshore of the southeast
coast today... As a surface cold front approaches the region
from the northwest. The remnants of tropical depression cindy
will cross the region with the cold front on Saturday. The front
then stalls farther south off the carolinas Sunday and Monday.

Near term until 8 pm this evening
Latest analysis reflects surface cold front aligned from the
western great lakes back into the mid-mississippi river valley.

Low pressure... The remnants of TD cindy now noted on early
afternoon vis IR satellite imagery lifting across the mid-south
toward the lower ohio river valley. Regional radar mosaic
indicating some isolated light to moderate showers pushing
across the area at 18z. However, latest mesoanalysis indicating
a capping inversion in place across the area. Question for the
balance of the afternoon is how quickly can we can destabilize
that cap enough to tap into convective potential. Time-lagged
hrrr and conshort blend has done well with convective trends so
far, and have leaned in its direction for the afternoon and
early evening.

Overall, expect mainly dry (albeit very warm and humid)
afternoon across the southern half of the area, with no real
discernible trigger and drier air filtering in from the coastal
carolinas. Therefore, will go no higher than a 20% pop for
isolated shower or t-storm. Farther north, cap should keep a lid
on pop, allowing little more than iso to widely scattered
convection through 00z. Well-advertised low- level jet analyzed
over E oh W pa, and should be far enough north to not have too
much of an impact with convective potential locally. Thus, pops
have been tapered down into 20-40% range over far NW zones
(cumberland, va to tappahannock, va to salisbury, md) for the
afternoon, with lower pops back into ric metro. Cams are at
least a little bit more bullish on convective development up
that way. Otherwise, very warm, breezy and moderately humid for
the rest of this afternoon with highs in the u80s to low 90s for
most inland, low to mid 80s along the atlantic coastal zones.

Heat indices ~100 through early evening.

Short term 8 pm this evening through Sunday
Rain chances in the short term mainly confined to late tonight
through Saturday night, as the remnants of cindy get absorbed
and essentially merge into a frontal wave, lifting from the
lower ohio valley toward the southern mid-atlantic late tonight
through Saturday afternoon.

Any scattered showers and storms quickly wane by early evening
with loss of heating. We are then mainly dry until after
midnight, as the surface front approaches from the nw, dragging
the remnants of TD cindy across the local area along with it.

The front will supply enough lift for a narrow area of showers
and an isolated thunderstorm moving across the area after
midnight tonight into early Saturday morning. Short-lived
moderate to heavy showers would be efficient rainfall
producers, but any flooding concerns would be limited, as
showers should be progressive. Partly to mostly cloudy outside
of any showers, and turning breezy overnight as winds increase,
owing to tightening pressure gradient between approaching front
and bermuda ridge offshore. Look for winds out of the SW to
gust to around 20-25 mph overnight. Early morning lows mainly
in the 70s.

Overall trend of 12z suite has been towards a more progressive
solution with the front and frontal wave (remnants of td).

Behind this feature, models are in good agreement with shearing
the precip apart Saturday morning. Meanwhile, an upper trough
over the midwest will slowly dig south and help to push the
front east across the area... As the bermuda high also retreats
to the east. Maintained 40-60% rain chances over the coastal
plain during this period for the afternoon and evening... And
into the overnight hours Sunday morning, as sct convection
develops as the front gets hung up across the SE coast into the
carolinas Sat afternoon and evening. Warm and muggy yet again
with highs Saturday generally in the upper 80s to around 90.

Cooler, drier air filters in from the northwest behind the
front for Sat night and Sunday, bringing a pleasant end to the
weekend wx-wise. Lows Saturday night in the low- mid 60s far
nw, upper 60s inland, lower 70s se. Dewpoints lower 60s NW to
lower 70s se. Lingering spotty convection along the albemarle
sound will come to an end Sunday morning with the rest of the
area remaining dry. A much more comfortable afternoon and
evening Sunday, with highs in the mid 80s (lower 80s beaches),
and dewpoints in the upper 50s NW to mid 60s se. Comfortable
sleeping weather Sunday night with lows in the upper 50s NW to
upper 60s se.

Long term Sunday night through Friday
Long term period will feature generally dry wx with slightly below
normal temps on avg. For Sun night mon, aforementioned cold front
pushes farther offshore leading to light NW flow and decreasing
clouds. After low temps in the 60s Sun night, expect high temps in
the low mid 80s mon. Another cold front crosses the area Mon night,
but the FROPA should be dry due to a lack of moisture. Cooler temps
then for Tue with highs only in the mid upr 70s most areas. Sfc high
pres builds directly over the area Tue night Wed behind a mid-level
trough pushing offshore. Dry again for Thu as the high slides
offshore allowing for S SW to develop across the mid atlc and temps
to MAX out in the mid 80s.

Aviation 20z Friday through Wednesday
Generally am anticipatingVFR conditions to prevail this afternoon
and evening. Brief periods of MVFR ceilings may be possible this
afternoon with a sct-bkn 2500 foot cloud deck. High resolution
models continue to hint at a few showers and potentially a rumble of
thunder impacting northern and western portions of the region later
this afternoon. Any showers that do redevelop will be highly
scattered in nature, but may produce periods of MVFR. All
precipitation is expected to taper off after sunset. A cold front
approaches western portions of the region by 08z bringing the next
chance for showers. The highest chance for rain will once again be
confined to northern and western portions of the region. Winds will
continue to be gusty this afternoon, occasionally gusting in excess
of 25 knots. Gusts to around 30 knots will be possible after
midnight as the cold front approaches the region and the gradient
tightens.

Outlook: scattered showers and thunderstorms may redevelop Saturday
afternoon and evening, bringing the potential for sub-vfr
conditions. Any shower activity comes to an end by early Sunday. A
return toVFR conditions is expected Sunday through early next week
as high pressure builds into the region.

Marine
Sca hazards continue as planned for tngt into Sat as the pres
gradient tightens ahead of an approaching cold front. Expect mainly
15-20 kt winds over all waters tngt, gusting up to 25-30 kt over the
ocean where seas will increase to 5-7 ft out 20 nm. Winds decrease
as the front slides through the area late sat, so all headlines will
end during the day sat, with the last ones being the northern cstl
waters for seas AOA 5 ft. Little in the way of CAA behind the front,
so anticipate winds mainly AOB 10 kt on Sun and mon, with 1-2 ft
waves over the bay and 2-3 ft seas over cstl waters. Another cold
front crosses the region Mon night, but again CAA is weak following
the front so expected sub-sca conditions. Sfc high pres returns for
the middle of 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.
