1015 am edt Mon sep 24 2018
High pressure will build to the north over new
england today and move offshore tonight. A warm front will lift
through the area Wednesday morning followed by a strong cold
front late Wednesday. High pressure will build over the region
again at the end of the week.
Near term through tonight
Minimal changes are needed to the overall theme of the forecast
other than adjusting for hourly trends. Areas of light rain and
drizzle abound across the area this morning. Some steadier rain
will gradually lift north across the area this afternoon and
evening, with the highest QPF still expected to be in western
maryland and eastern west virginia. The best forcing is
expected west and north of the area, so am still thinking any
flooding is a low probability. Temperatures will be holding
fairly steady or only rise a few degrees through the day.
surface wedge is expected to strengthen today as strong high
pressure builds across southern quebec and northern new england
today. Meanwhile, isentropic lift is expected to increase later
today into tonight along with rrq jet dynamics. This is expected
to result in another period of steady light to moderate rain
today into Tue morning. Heaviest amounts are expected across
wrn md and ERN wv. However, the latest guidance has trended
lower with QPF amnts than 24 hrs and the overall amounts should
be lower than yesterday. Given stratiform nature of precip and
downward trend in QPF from models will hold off of any flood
watches attm. Marfc has some fcst points on the potomac and
northern shenandoah getting close to minor flooding Tue night.
These were run with higher QPF from 24 hrs ago.
Short term Tuesday through Wednesday night
Steady rain will probably linger into Tue morning across
northern md into SRN pa. Otherwise, expect steady rain to end
by afternoon as h850 warm front lifts north of the area with
drizzle or mist possible due to drying aloft and upslope flow.
Then, attention turns to next cold front fcst to cross the area
late wed. Area should get into the warm sector Wed with modest
destabilization expected. SPC has area under slight risk of
severe wx wed. Brief heavy rainfall is also possible as front
crosses the area.
Long term Thursday through Sunday
After a pretty wet majority of the week, improving weather is
forecast by the end of the week and over the weekend.
The frontal boundary that moves across the area Wednesday will
likely stall out offshore and southwestward into southern va and
north carolina for Thursday and Thursday night, as a weak surface
wave moves along it. At the same time, a ~1025mb surface high will
build into southeastern canada and wedge down the northeastern us
coastline, helping to induce northeast surface flow. Aloft,
southwest flow will persist, and a return of warm moist air
advection will likely occur. The region is also progged to be in the
right entrance region of an upper jet. This all spells out a day
that will likely end up on the cool cloudy side with increasing
chances for showers by Thursday afternoon and Thursday night,
especially south. The extent location of which will be determined by
the eventual location of the boundary and how much dry air can push
southward. Highs in the 60s to around 70f.
The frontal boundary will begin to clear eastward by Friday as a
secondary front passes by to the north. High pressure will begin to
build into the region by late in the day. This should lead to drier
weather although a few lingering showers will still be possible.
Highs should rebound back to near or above normal, in the 70s to
A baroclinic zone is then expected to set up from the midwest
eastward into new england which will serve as the focus for frontal
systems into the following week, with the mid-atlantic on the warm
side. High pressure will generally build overhead on Saturday and
Sunday, with a system passing north Saturday night into Sunday along
that zone. Temperatures should generally run above climatology, with
highs in the 70s to near 80f and lows in the 50s to near 60f.
Aviation 14z Monday through Friday
Ifr (perhaps lifr at times) conditions are expected today into
tonight. CIGS may improve to MVFR briefly (currently this window
is around bwi mtn), but duration of such improvement is
uncertain. Rain and drizzle will also reduce visibility at
times. Improvement to MVFR category is not likely until tue
when sfc wedge begins to weaken. Showers and sct t-storms are
anticipated Wed afternoon with gusty winds and temporary
reductions in CIGS and vsby.
Potential exists for sub-vfr conditions Thursday as a stalled front
may will likely lead to areas of low clouds showers.VFR will return
Friday under building high pressure.
Easterly flow is taking some time to increase, but is still
projected to reach SCA criteria this afternoon. SCA conditions
are then expected into tue. Winds should begin to diminish
tonight as onshore flow weakens, but likely won't drop off below
sca until sometime tue. Smws may be required on Wed with
thunderstorms associated with a cold frontal passage.
Sca conditions are possible Thursday as northeast winds increase
behind a frontal boundary. Sub-sca conditions should return Friday
as the system departs.
Tides coastal flooding
Anomalies are increasing again on easterly flow. The potomac is
first to see these effects, with advisories for straits point,
dahlgren, and dc. More widespread advisories will likely be
needed tonight into Tuesday. Straits point has the highest
chance of reaching moderate stage, and thus a coastal flood
watch is in effect for several tide cycles.

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.
