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 cold front has moved offshore this morning. High pressure
will build in from the midwest tonight. This high will move
overhead Sunday and then progress offshore Monday into Tuesday.

An area of low pressure is expected to pass well to our north
for midweek but not before its cold front moves through the
region on Wednesday. Canadian high pressure building into the
mid atlantic on Thursday will likely influence our weather
through early next weekend.

Near term until 6 pm this evening
The cold front has moved offshore this morning, and a west-
northwest flow has developed. Winds will become more west-
southwest later today as a surface trough approaches from the
west. Some daytime cumulus has begun to develop across the area
and will continue to build through the day, although there
should still be plenty of sunshine through the day. As the surface
trough moves across the area today, a short wave vorticity
impulse approaches later in the afternoon as well. A few
showers thunderstorms are expected to approach the area later in
the afternoon, but probably won't move across the area until
this evening.

Dewpoints today will be lower for most places than Friday, but
still in the mid to upper 60s with some 70s mixed in.

Temperatures will be well above normal again today, but with the
expected dewpoints, heat index values will remain in the 90s so
not expecting to reach heat advisory levels.

Short term 6 pm this evening through 6 am Sunday
The axis of the upper trough will cross the region tonight with a
shortwave rotating through the area with it. The models continue to
show some moisture crossing the region with the shortwave upper
trough. It appears that the moisture peters out before reaching the
majority of our area and only a few showers, possibly an isolated
thunderstorm, may reach the lehigh valley, poconos and northwest
new jersey.

Overnight lows will generally be in the 60s across the region,
closer to 70 in philadelphia and along the coast.

Long term Sunday through Friday
High pressure centered over the ohio valley Sunday morning will move
overhead by Sunday night. The high will gradually shift off the
coast on Monday, but not before it provides us with consecutive days
of dry weather and seasonably warm temperatures (highs in the mid to
upper 80s both days). An uptick in humidity will occur on Monday in
response to the light southerly return flow that develops on the
western periphery of the surface high.

Due to popular demand, spent a little extra time than usual
analyzing moisture fields from various models before constructing
cloud cover forecast for Monday afternoon. We are advertising a
mostly sunny sky during the 1-4 pm timeframe when the solar
eclipse will be viewable in our area. However, there are a couple
of things to watch out for that could provide a source of clouds:
1) there will likely be high-level cirrus streaming in from the
west with a subtle upper-level jet streak passing by but it should
generally be scattered and or thin enough to not impede viewing of
the eclipse. 2) daytime heating will result in the development of
cumulus (cu). Based on the newest 00z guidance, expect these
lower-based clouds to be scattered across a majority of the area,
allowing most sky gazers to have a unobstructed view of the
eclipse. However, with increasing moisture in boundary layer, it
is still too soon to rule out a broken CU deck that could impact
viewing, especially south and west of philadelphia where mixing
ratios and rh values are higher at the top of the boundary layer
between at 18z and 21z. It will also be interesting to see how the
temporary lull in insolation during the solar eclipse will affect
cloud cover- one would expect the diurnally-driven CU to decrease
around and just after totality in a similar manner to what happens
near sunset on a normal day.

Our next chance for precip looks to be Monday night when a weak
shortwave trough embedded within a corridor of stronger westerlies
residing to the north of the southern CONUS upper ridge is
predicted to pass through the region. This disturbance could
provide enough lift to support elevated convection into the night,
especially across DELMARVA and southern nj where the airmass will
be more moist and less stable compared to more northern locations.

Low pressure is expected to deepen midweek as it tracks
northeastward across the great lakes and into the st. Lawrence
valley. Meanwhile, shortwave energy digging around the backside
of the synoptic trough will lead to amplification of this
upstream trough. In this pattern, chances for showers and storms
will increase going into Tuesday and Wednesday. The focus for
convective development Tuesday afternoon will be along a pre-
frontal trough that is forecast to sharpen to the lee of the
mountains. Tuesday looks to be the hottest day of the period
(lower 90s along and south of the urban i-95 corridor) with the
warm sector becoming established over the area in advance of the
cold front. The best opportunity for rain looks to be Tuesday
night and Wednesday in concert with the arrival of the cold
front. Note, models are in remarkably good agreement
(considering its still five days out) with the position and
timing of the surface low and attendant cold front.

Expansive high pressure builds in from the great lakes late in the
week and into the start of next weekend. The Thursday-Saturday
period is currently forecast to be dry with slightly below normal
temperatures,. However, we will have to monitor the potential for
the front that moves through midweek to stall nearby, which
frequently occurs in summer.

Aviation 16z Saturday through Wednesday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Rest of today and tonight...VFR conditions are expected. West
to northwest winds around 5 to 10 knots with a few gusts around
15 knots this afternoon. Winds will become light and variable
overnight tonight. An isolated shower or thunderstorm possible
late this afternoon and evening near krdg kabe.

Outlook...

Sunday through Monday night...VFR. NW 5-10 kt on Sunday, becoming
calm after sunset, then s-sw 5-10 kt on Monday.

Tuesday... MainlyVFR. Low chance for showers and storms with the
potential for convective development being slightly more favorable
over western-most terminals. S-sw winds 5-10 kt with gusts 15-20 kt
during the afternoon.

Tuesday night and Wednesday... Increasing chances for showers and
storms with the approach of a cold front. This activity will bring a
risk for temporary localized restrictions belowVFR. Expect a wind
shift from s-sw to NW to occur on Wednesday with fropa.

Wednesday night... Improving conditions from NW to SE behind the
front.

Marine
Tranquil conditions will continue across the area waters through
tonight. Northwest winds becoming southwest later today around
10 to 15 knots with a few gusts around 20 knots through tonight.

Outlook...

Sunday through Tuesday... Winds and seas will be well below sca
criteria.

Tuesday night... SCA possible with sly flow strengthening ahead of
cold front. Seas may also build to near 5 ft in our coastal waters.

Wednesday... Winds veer from s-sw to W with the arrival of a cold
front. Wind speeds should be below 20 kt but it may take time for
seas in the coastal waters to drop below 5 ft during the morning.

Wednesday night... Nw winds could briefly approach 25 kt in post-
frontal pressure surge.

Rip currents...

the rip current risk for today is low at the new jersey shore and
delaware beaches.

Phi watches warnings advisories
Pa... None.

Nj... None.

De... None.

Md... None.

Marine... None.
