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
Canadian high pressure will build southward into the region through
this weekend before progressing offshore around the middle of
next week. This high will bring a period of dry and seasonably cool
weather to the mid-atlantic through at least the beginning of
next week. A tropical or subtropical low is expected to develop
east of the florida coast this weekend and lift slowly
northeastward off the east coast next week. At this time, the
system is expected to remain well southeast of the area.

Near term until 6 pm this evening
The cold front is now well off shore. In its wake, a surface high
will be slowly building towards our region. With some continued weak
cold air advection, expect highs today to be near or slightly lower
than yesterdays highs, ranging from the lower 70s to mid 80s across
the region.

Short term 6 pm this evening through 6 am Friday
There is a small chance that showers could move into western
portions of the region as a mid and upper level short wave trough
approaches from the west. However, dew points are already quite low,
and expect them to drop even more before tonight. The drier air,
combined with the climatologically unfavorable timing, favors a dry
forecast at this time.

Lows are expected to be slightly below normal with radiative cooling
slightly tempered by cloud cover.

Long term Friday through Wednesday
The main concerns for the long-term forecast are a prolonged
period of mostly dry and seasonably cool weather through early
next week followed by large uncertainty regarding the evolution
of two tropical systems.

The forecast for Friday through Monday is fairly
straightforward. A large-scale trough will progress through the
great lakes and the northeast through the period, with smaller-
scale vorticity maxima progressing around the larger-scale
trough. One of these perturbations should be advancing through
new england at 12z Friday, and cold air advection on the
upstream side of the shortwave trough should reinforce the
cooling trend already commencing in the region. Forecast highs
should be around five degrees or so below seasonal averages, and
forecast lows Friday night may be 5-10 degrees below average.

Latest mex ece numbers are well below 50 in the poconos, and it
is not out of the question philly may dip below 60. Similarly
cool conditions are expected on Saturday.

Another shortwave trough digs southeastward Saturday night,
which should make for another cool dry day Sunday. The timing of
this trough is unfavorable for development of diurnal showers in
our area, and given the strong model agreement on timing, kept
pops unmentionable during this period. Overall, a banner
weekend is anticipated.

The large-scale trough progresses off the coast Monday, and an
omega block sets up in its wake. This places the region in
upper-level ridging, with the attendant surface high progressing
eastward to new england and adjacent portions of far southeast
canada. This will set up a prolonged period of easterly flow in
the region. Meanwhile, a tropical wave over florida late this
week is projected to drift into the adjacent atlantic waters
this weekend. With little steering flow, weak shear, and very
warm waters, global models are suggesting somewhere between slow
and rapid development of this wave into a tropical subtropical
cyclone. In general, the 00z gfs ECMWF are similar in the
development of this low and its eventual track northeastward
well away from the mid-atlantic. However, given the blocky
nature of the flow to the north, there is fairly large
uncertainty with this system. The 00z cmc paints a much more
ominous picture, for example (a tropical system moving into
chesapeake bay by midweek). Though this solution is low-
probability (quite the outlier), it does suggest that this
period of the forecast is subject to considerable
change uncertainty.

Nevertheless, the presence of this developing system indicates
that (1) surface onshore flow will persist strengthen during the
early to midweek period as the surface pressure gradient
increases, (2) conditions may deteriorate (i.E., increased
cloud cover and potential for showers rain with time, mainly for
southern eastern portions of the cwa), and (3) coastal flooding
concerns may be present next week.

Then there is TC harvey. Although its effects for our region
appear to be outside of the next seven days, it will remain a
player in the forecast for a long while. With an upper low in
the central u.S. Midwest likely to be present during this
period, harvey will eventually lift northeastward.

When where how remain question marks, but it necessitates close
monitoring for the next several days.

Aviation 10z Thursday through Monday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Vfr conditions are expected through the TAF period. Increasing
mid level clouds are expected later today, but any ceilings will
easily beVFR.

Wind speeds will be light (less than 10kt) throughout the TAF period.

Wind direction, though starting out variable, will eventually
settle in out of the northwest.

Outlook...

Friday through Monday:VFR. Winds slowly veering from N or NW on
Friday to N or NE on Saturday to E or NE Sunday and Monday, with
speeds generally at or below 10 kts through Sunday but slowly
increasing Monday. The strongest winds should be near the coast.

Marine
Winds and seas are expected to remain below small craft advisory
conditions today and tonight.

Outlook...

Friday through Saturday night: winds and seas below advisory
criteria. Fair weather.

Sunday and Monday: northeast to east winds will be increasing
during this period, with gusts potentially exceeding advisory
criteria by Sunday night. Seas will also build and will likely
exceed 5 feet by Sunday afternoon or evening.

Rip currents...

there is low risk for the development of dangerous rip currents
today. The low risk is forecast to continue through Saturday.

Early next week... The risk for the formation of dangerous rip
currents may increase depending on the the actual development-
building of 8 second easterly swells.

Climate
Kabe monthly rainfall is now 8.34 inches... Still ranked #12 for
the month of august. The record is 13.47 inches in 2011.
