318 am edt Wed may 22 2019

Synopsis
High pressure will build into the area today bringing dry and
pleasant weather. A warm front will pass through the area tonight
with a cold front arriving Thursday night into Friday morning.

High pressure will again be nearby the area Friday and into
Saturday. A cold front will likely cross the region late Saturday
into early Sunday potentially stalling just our south towards the
start of next week.

Near term today
Generally expect a quiet day weather-wise as surface high
pressure shifts overhead and then crests the area this
afternoon. The airmass will be quite dry with light winds an
generally seasonal temperatures. Cloud cover will generally be
limited to cirrus. The flow will become more southerly behind
the high later in the day, and given this weak onshore gradient
expect a sea breeze to develop (despite a somewhat limited
thermal contrast) and push inland by late afternoon. The main
effect this may have is cool maxes along the immediate coast
relative to yesterday.

Short term 6 pm this evening through 6 am Thursday
Deep southwesterly flow tonight will result in warm air advection
aloft along with fairly robust moisture advection (pwats initially
around 0.5 inches Wednesday increasing to around 1.5 inches by
Thursday am). This combined with weak shortwave energy moving into
the flattening ridge will result in a chance of showers and possibly
a few elevated thunderstorms tonight into Thursday morning.

Currently the greatest elevated instability looks to reside over
eastern pa NW nj and consequently currently have highest pops QPF in
these areas. Think that initially dry low lvls and meager
instability will preclude any strong storms heavy rainers in this
time frame but a few locations could receive a few tenths of rain
under any stronger storms.

Long term Thursday through Tuesday
Longer term forecast looks on track and minor adjustments made
using latest guidance.

Thursday morning into mid afternoon looks dry with temperatures
rising into the upper 70s or lower 80s. South to southwest low level
flow will transport mid 60s dewpoints into the region by afternoon,
a noticeable increase from early morning readings around 50.

It looks like Thursday late afternoon into the evening is going to
be an active period. Low pressure currently moving northeastward out
of the plains will make a hard turn to east as it nears the western
great lakes. It then turns southeast as it rounds the top of the
southeast ridge. Guidance is in good agreement on the surface low re-
strengthening as it makes this turn, which will be accompanied by
strengthening wind fields. All in all, what appears to develop over
the mid-atlantic Thursday evening is a rather favorable environment
for severe weather, primarily damaging winds and large hail. As
night falls, a nocturnal inversion will probably start to develop,
cutting off the surface based instability. SPC has placed much of
central and eastern pennsylvania in an enhanced risk for severe
thunderstorms for Thursday with a slight to marginal risk eastward
to the coast.

Behind the front, high pressure will be firmly in control for what
looks like a warm and pleasant day Friday. Dry weather continues for
the overnight.

High pressure should allow dry weather to continue for most of the
day Saturday. A warm frontal passage is likely early on Saturday,
which should set up a warm afternoon away from the coast where a
lingering onshore wind will keep things cooler. By Saturday evening
and overnight, the next cold front will be approaching as the parent
low tracks through ontario. This will bring a renewed threat of
showers and thunderstorms.

The front should get just far enough south on Sunday to put us in a
true post-frontal air mass. It continues to look warm as well with
winds turning westerly. Mid to upper 80s are likely in most areas.

Very low confidence as model timings are drastically different with
the approach of the next frontal system. Best thinking at the moment
is another fairly warm day on Monday with a late day shower or storm
risk as a front approaches. This would yield drier weather for
Tuesday. However, much fine tuning will need to be done here.

Aviation 07z Wednesday through Sunday
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.

Today ...VFR conditions expected through the day. Light winds this
morning will shift to light southerly southwesterly by this
afternoon. These southerly winds may increase, initially at the
coastal sites, in the mid-late afternoon period as a sea breeze
develops and moves inland.

Tonight... MostlyVFR with increasing mid-lvl clouds, although
periods of MVFR rain will be possible particularly at kabe and krdg.

Winds will generally be light favoring a southerly direction.

Outlook...

Thursday-Thursday night... Most of the daytime Thursday should be
vfr. Thunderstorms possible Thursday evening. Southwesterly winds
shifting to northwesterly Thursday night. Gusts to 20 kt possible
during the day Thursday.

Friday-Friday night... VFR. Northwest wind gusting up to 20 kt,
becoming northeasterly and decreasing Friday night.

Saturday-Saturday night... VFR expected most of the day Saturday.

Showers and thunderstorms possible Saturday evening and overnight.

Winds gradually shifting from east to south on Saturday then south
to west on Saturday night.

Sunday... VFR. Light west-northwest wind.

Marine
Today tonight... Sub-sca conditions expected with northerly
winds this morning shifting to easterly and then
southeasterly southerly by the afternoon. Seas will be around
2-3 feet.

Outlook...

Thursday-Sunday... A period of SCA conditions due to southwesterly
winds gusting near to above 25 kt is possible Thursday afternoon and
into the first part of the overnight. Otherwise, winds and seas are
expected to remain below SCA criteria.

Rip currents...

a low risk of rip currents remains on tap for tomorrow, although
a sea breeze with associated onshore flow looks to develop by
tomorrow afternoon.

Equipment
The kdix radar is back online. However, it will be in a test phase
through this afternoon. Intermittent outages are possible.

Phi watches warnings advisories

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.
