What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
High pressure across our region will gradually shift offshore
Friday. A weak cold front moves southward across at least parts of
our area late Saturday night and Sunday, then stalls in our area
through Monday. A secondary cold front moves through during Tuesday,
followed by high pressure Tuesday night before it moves offshore
during Wednesday. A warm front may approach on Thursday.

Near term until 6 am Friday morning
High pressure centered over the great lakes ohio valley continues to
build east tonight.

Clear skies and light winds on tap for tonight, and this should
result in radiational cooling away from the urban centers. Lows will
range from the mid 50s in most of nj and eastern pa, upper 50s in
the delmarva, and in the lower 60s along the i-95 corridor from
trenton to philly. Patchy radiational fog is possible, mainly in the
sheltered valleys.

Short term 6 am Friday morning through 6 pm Friday
High pressure continues to build east on Friday. Winds shift to more
of a southwest flow and tap into some gulf of mexico moisture.

Surface dewpoints will rise into the 50s and humidity levels along
with temperatures will creep up a bit. Afternoon sea breezes will
likely not make as much westward progression due to the increasing
offshore wind. Most likely areas that could sea breeze will be right
along the nj coast.

Warmer temperatures expected with highs generally in the mid to
upper 80s, except a bit cooler in the mountains and along the
coast.

Long term Friday night through Thursday
Summary... Very warm and more humid over the weekend, although some
cooling should occur Sunday into Monday. Increasing chances of
showers thunder during the holiday weekend, with perhaps some
drying as we go through next week.

Synoptic overview... The flow aloft is forecast to become more blocky
in nature with a closed low in the west and a closed low in the
vicinity of the central gulf coast. Meanwhile, a ridge is near the
plains with some troughing sliding near the great lakes and
northeast. This offers not much change, however the details become
less clear especially with the extent of impacts associated with a
cold front sliding southward from new england later in the weekend
and early next week. In addition, tropical moisture is forecast to
surge northward from the gulf of mexico associated with the
aforementioned trough aloft and surface low development. This all
occurs as a ridge remains situated off the southeast u.S. Coast. The
theme in the guidance continues to show increasing chances for
convection during the holiday weekend. It does not appear to be a
washout, however there looks to be times where it will be
convectively active. The trough in eastern canada and the northeast
may then amplify enough during Monday and Tuesday along with the
passage of a cold front to push the deeper moisture to our south and
east.

For Friday night... High pressure at the surface is forecast to be
centered in the western atlantic. The flow across the mid-atlantic
is more zonal, however a short wave trough is forecast to be
shifting east-southeastward from the midwest and upper great lakes.

A continued southwesterly flow will allow for increasing moisture
advection therefore it will start to become a bit more humid through
the night. A precipitable water surge to around 1.5 inches is
forecast to overspread at least the southern half of the area toward
daybreak Saturday. The gradual increase in surface dew points will
result in a warmer night, and some higher level clouds may cross the
area at times.

For Saturday and Sunday... A ridge remains centered off the southeast
u.S. Coast with a ridge into the plains and closed low out west.

Some northern stream energy however allows for a short wave trough
to slide eastward from the great lakes region while a more
pronounced upper-level trough moves across the canadian maritimes.

The latter has surface low pressure tied to it and a trailing cold
front is forecast to settle southward into our area. The forecast
challenge continues to figure out how far south this front gets
Sunday and how strong the southwestward push from high pressure is
for a time. Prior to this, southwesterly flow will maintain very
warm and humid air across the region. A plume of precipitable water
around 2 inches overspreads the area Saturday. Within this plume,
increasing instability along with some northern stream short wave
energy should initiate some convection especially from late morning
through the afternoon on Saturday. This should be mostly focused
across the western zones to start, potentially tied to a weak lee
side trough and terrain circulations, then shift eastward through
the day. Convection on Saturday could be enhanced some if the short
wave trough from the west ends up providing more support.

There will be additional convection on Sunday especially in the
afternoon and evening as the surface cold front sags southward which
should provide a bit more convergence. While the deeper tropical
moisture plume may reside just to our south, plenty of moisture in
our area combined with possible slower storm motion and training may
result in a local very heavy rain flood threat. The extent of this
is of lower confidence at this time.

For Monday and Tuesday... The overall pattern does not change much,
although there may be more of an influence of an upper-level trough
in the northeast. While a residual frontal zone should be in our
vicinity Monday, low pressure is forecast to track well to our north
with another cold front moving through during Tuesday. Some
convection should occur especially Monday, however the extent of it
is less certain. There will be a tropical moisture plume still just
to our south, and if this is more involved across our area then an
enhancement to daytime convection is possible. Despite another cold
front moving through on Tuesday, showers thunder may end up being
more limited especially if a short wave trough is a little faster
and allows for some drying to occur from the northwest.

For Wednesday and Thursday... A trough aloft may still be across the
gulf coast beneath a ridge to its north. The ridge across parts of
the great lakes should shift eastward some, allowing surface high
pressure to build into our area. A front will be lurking to our
south with tropical moisture residing to its south, therefore the
placement of this will be key regarding any shower thunder chances
for parts of our area. More uncertainty at this time frame as
convective changes will depend on the track of a trough aloft as
well as a plume of tropical moisture as high pressure shifts
offshore.

Aviation 20z Thursday through Tuesday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

This afternoon...VFR and clear skies will continue. With high
pressure building in from the nw, N winds should gradually weaken
and may become light SW by evening. Another factor is the sea breeze
front which is already apparent on radar as of early afternoon. This
will cause a wind shift to the SE at around 10 kt at acy by 19z or
so, and also miv a couple hours later. This sea breeze could reach
phl and nearby terminals around 23z to 00z. High confidence except
for sea breeze timing.

Tonight...VFR with clear skies continues. With high pressure
offshore, winds will be SW around 5 kt or less. High confidence.

Friday... StillVFR and mostly clear skies. High pressure moves
farther offshore and SW winds will increase to 10-15 knots with
possible gusts up to 20 knots. Moderately high confidence.

Outlook...

Friday night...VFR. Southwest winds less than 10 knots.

Saturday and Sunday... Times of sub-vfr conditions with some showers
and thunderstorms, especially each afternoon and evening.

Monday and Tuesday... Sub-vfr conditions possible at times due to a
chance of some showers and thunderstorms.

Marine
Winds shifting to the SE through this evening at less than 10 kt,
and will become SW tonight. Pressure gradient tightens on Friday,
but think there will be a strong enough inversion to keep wind gusts
capped at sub-sca criteria. Best chances for 25 kt wind gusts Friday
afternoon will be in northern nj ocean waters, where the ambrose jet
may result in locally stronger wind gusts. Seas on ocean 2-4
feet.

Outlook...

Friday night and Saturday... Southwesterly winds may gust to near 25
knots at times. The overall mixing should be limited some due to a
much warmer airmass moving over the cooler waters. Seas should be 4
feet or less.

Sunday and Monday... The conditions should be below small craft
advisory criteria, however a cold front from the north sags into our
area and this will have an impact on the wind direction.

Tuesday... The conditions should be below small craft advisory
criteria.

Rip currents...

the risk of rip currents through this evening is low. Despite
an onshore component to the flow with speeds 8-12 kt, wave
heights and swells are forecast to be near 2 ft.

Phi watches warnings advisories
Pa... None.

Nj... None.

De... None.

Md... None.

Marine... None.
