What's New / NOTES
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Synopsis
A weak backdoor frontal boundary will hover near the area today,
lifting northward as a warm front tonight into Monday. An upper
level disturbance will approach the area from the southwest
later this afternoon and evening. A cold front is slated to
cross the region Tuesday evening with high pressure building
overhead for the remainder of the work week.

Near term through tonight
Mostly clear skies prevailing early this morning under calm
winds across the region. The clear skies have allowed
temperatures to radiate nicely with temperatures generally in
the 20s, and near the freezing mark in the city centers. A weak
frontal boundary resides across pa, bringing an increase in
cloud coverage over that region. This frontal boundary will
sneak slowly southward today, before lifting northward as a warm
front by this evening as a shortwave approaches the region from
the southwest.

High pressure off the southeast coast today will continue to
slowly drift eastward over the western atlantic, maintaining
generally light southerly winds across the area and near normal
temperatures in the mid to upper 40s. The aforementioned
shortwave that will approach from the southwest today will bring
an increase in cloud coverage by this afternoon, as well as an
increase in low level moisture. Model guidance in good agreement
with some showers developing across the area by this evening,
but they will remain light. Expecting liquid precipitation with
these showers as temperatures at the surface and aloft will
generally be above freezing. A few ice pellets could mix in over
our northern zones near the mason dixon and the allegheny
front, resulting in little to no impacts. Temperatures
overnight will fall in to the low to mid 30s.

Short term Monday through Tuesday night
Weak high pressure will build over the area on Monday with some
light showers possible along the allegheny front with minimal
accumulations expected. Overall dry conditions and moderating
temperatures expected for the region Monday and Monday night.

Highs on Monday will top out in the low to middle 50s and settle
down to in the upper 30s to near 40 degrees Monday night.

Another mild day on tap on Tuesday with highs approaching 60
degrees with a southwest flow. A surface trough and associated
cold front will cross the region overnight Tuesday, trending a
little later than previous guidance. Not much fanfare in the way
of precipitation as this front approaches, mainly upslope
rain snow shower across our far western mountains as winds turn
northwesterly in its wake. Temperatures Tuesday night will
remain above average from the middle 30s to near 40 degrees in
the cities.

Long term Wednesday through Saturday
Southern stream shortwave energy will be undercutting the forecast
area Wednesday into Wednesday night. Some timing and placement
discrepancies linger with respect to this wave, but the consensus
seems to be converging on a solution that keeps most of the forcing
south of the area... Which precludes the need to identify specific
precipitation type(s). A consensus approach suggests that lows will
be below freezing, but thermally that should occur after any precip
falls (if there were any). Will allow for a slight freezing chance
in the database to maintain a pinch of consistency, but latest
trends suggest this won't be a factor.

In the wake of this disturbance, believe that there will be a dry
period, as a ridge of high pressure builds from the north. That
should encompass at least Thursday and Thu night. Beyond that, the
problem becomes timing. A fairly well defined frontal system,
attendant to a relatively strong northern stream low, will arrive
by around Saturday. Potentially a warm front will be crossing first,
somewhere in the late Friday Friday night time frame. Temperatures
will be key in determining precip type... Particularly at night. Will
lean toward the warm side... Not just to simplify the weather
forecast, but also that is in line with the latest blended guidance.

Anticipate future runs will vary as guidance seeks a solution that
can be locked in.

Aviation 07z Sunday through Thursday
PredominateVFR conditions are expected across the terminals
through Monday night under a light wind flow regime. A weak
upper level disturbance may spark a few showers late Sunday
afternoon and evening, but at worse, only brief reductions in
vis CIGS expected along and north of mrb bwi mtn.VFR conditions
continue on Tuesday with a mostly dry cold front expected to
cross the terminals overnight Tuesday.

Vfr flight conditions anticipated wed-thu.

Marine
With high pressure in control over the southeastern u.S., light
winds will prevail across the waters through Monday night. A
cold front will approach from the west on Tuesday, increasing
winds out of the southwest, but expected to remain below sca
criteria. A cold front will push through the area overnight
Tuesday, increasing winds out of the northwest. SCA conditions
likely in the wake of the frontal passage.

Winds should remain below critical thresholds wed-thu. Northwest
flow will be decreasing wed. While the deterministic gust
forecast will be no higher than 15 kt, some guidance sources
suggest small craft advisories may extend into wed. As high
pressure builds thu, flow should become light.

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.
