Synopsis
A cold front will continue to push to our south overnight, then
high pressure builds to our north Monday and Monday night. This
high builds offshore to or northeast on early Tuesday, while a
frontal boundary lifts across our area. This front may stall
through Wednesday while a couple of low pressure systems move
eastward along the boundary. This front lifts to our north
Wednesday night, before a couple of cold front move across the
area later Thursday into Friday.

Near term until 6 am Monday morning
Convection continues over central pa. So far, the storms
haven't shown a persistent severe threat. Part of this could be
due to the fact that anvils are spreading out in the direction
of travel of the storms, which is causing the air immediately
downstream of the storms to be slightly cooler. Also, it looks
likely that the dry air in the mid levels is still in place, as
evidenced by the surface dewpoints decreasing as the mixing
layer increases. Further, the convective temp on the 12z iad
sounding was above 90, so we still have a few decrees to go to
erode the cap.

None the less, still expect the risk of severe storms to
increase as we head into the late afternoon, especially as the
front approaches our region. Therefore, have kept a mention of
severe storms in the forecast, and will continue to monitor the
radar trends. It still looks like the highest risk is from
philadelphia southward, where MLCAPE values could get close to
1000 j kg. Additionally, bulk shear values (almost entirely
speed shear) will be near 40 kts.

The primary hazard looks to be damaging winds (possible both
due to stronger winds mixing down, and some downburst potential
with mid level dry air entrainment). It looks like the hail
threat may be more limited than previously expected as the cape
profile is mostly below the hail growth region. I still can't
rule it out though, so will continue to mention in the hwo.

Still looks like the tornado threat is negligible as there is
very little shear within the boundary layer.

Storms should shift south through the evening. By midnight,
storms should be mostly confined to delmarva. The severe threat
should also end by midnight as well as the low level inversion
develops behind the cold front.

For the rest of the region, drier air should start to filter in
behind the cold front late this evening, leading to clearing
conditions. Depending on how quickly the front arrives,
temperatures could drop into the 50s, but more likely, low level
moisture will keep temperatures from dropping below 60 for much
of the area.

Short term 6 am Monday morning through 6 pm Monday
Memorial day should be a pleasant day for much of the region.

The only possible exception is portions of delmarva. If the
front stalls over this area, showers and storms could linger in
delmarva through the day. Although there is still some
uncertainty, so I stayed close to the previous forecast, it is
worth noting that some of the 12z models show this front
clearing much further south, leaving the entire region dry.

Temperatures behind the front will be 5 to 10 degrees lower
than Sunday, with highs mostly in the 70s and lower 80s. Despite
the northwesterly flow, a sea breeze could develop later in the
day, cooling coastal areas further.

Long term Monday night through Sunday
An unsettle pattern continues for much of the upcoming week
into the weekend, with several rounds of showers and
thunderstorms.

Monday night will start out fairly quiet as high pressure
builds to our north. Very late in the night, the high pressure
begins to lose any grip it has on our area as a frontal boundary
begins to lift northward, and as a short wave vorticity impulse
moves into the area, scattered showers and thunderstorms may
develop late Monday night into early Tuesday morning.

As we go into Tuesday, the front lifting toward the area is
forecast to slow down and may stall out across the region later
Tuesday, into Tuesday night, and into Wednesday as well as
several waves of low pressure move along the boundary. As
multiple rounds of short waves vorticity impulses aloft move
across the area within the northwest-west flow aloft, showers
and thunderstorms will continue in the forecast Tuesday-
Wednesday, although it will not rain the entire time. The higher
probabilities will be tied to the passages of the short waves.

As we move into Wednesday night, the frontal boundary is
expected to lift to our north, and precipitation chances will
lower through Wednesday night, although not be zero as there
will remain unsettled conditions with an additional short
wave vorticity impulse affect the area.

On Thursday and Friday, a couple of frontal boundaries are
forecast to move across the area. The front on Thursday
currently looks to be the stronger of the two, and has a better
chance of showers and thunderstorms to be associated with it.

Thursday also has higher pw values at 1.5-2.0 for some areas, so
it will have a higher threat for heavy rainfall, although pw
values remain over an inch into Friday.

Dry weather may return for early Saturday as high pressure
briefly builds across the northeast and into our area. However,
showers may begin to develop during the afternoon as return flow
develops and a short wave moves across the area. Also, another
cold front is currently forecast to move toward the area on
Sunday, which could bring another round of showers and
thunderstorms to the area.

Temperatures through most of the extended period are forecast
to be above normal, with Tuesday possibly being the coolest day
and below or near normal.

Aviation 19z Sunday through Friday
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.

Today...VFR conditions are expected to continue through 18z.

After 18z, there is a chance for tsra across the region. Any
storms will be capable of variable and gusty winds, and possibly
some hail. At this point, have a tempo group to include the
threat with the first potential round of storms, but additional
rounds of storms will be possible continuing into the tonight
period. Winds will generally be from the west around 10 kts with
occasional gusts to 15-20kts.

Tonight... Showers thunderstorms will continue to be possible
through 06z. Once storms move south of the TAF sites, expectVFR
conditions for the remainder of the night. Winds shifting more
northerly overnight, but speeds should stay near or below 10 kt.

Monday...VFR conditions are expected with northerly light winds
through the day. The one exception is that a sea breeze could
develop after 18z which could shift winds at kacy and kmiv to
southeasterly.

Outlook...

Monday night... GenerallyVFR condition expected, although
clouds increase and lower late in the night with a chance of
showers. Winds become northeast 5-10 knots overnight.

Tuesday-Tuesday night... MVFR ceilings may develop early Tuesday
as a warm front lifts across the area and continue into the
night. Chance of showers and thunderstorms during the period.

East to northeast winds Tuesday and Tuesday evening, become
southeast Tuesday night.

Wednesday-Wednesday night... MVFR conditions possible early,
then lifting toVFR during the morning. Showers and
thunderstorms remain possible, especially Wednesday afternoon
and evening. Winds shift to southwest early and may gust 15-20
knots during the day.

Thursday-Thursday night... GenerallyVFR, except lower
conditions possible with showers and thunderstorms Thursday
afternoon and night. Southwest winds may gust 15-20 knots during
the day Thursday.

Friday... GenerallyVFR, except lower conditions possible with
showers and thunderstorms during the day. Southwest winds may
gust 20-25 knots during the day.

Marine
Winds and seas are expected to remain below small craft
advisory conditions through memorial day. Thunderstorms with
gusty erratic winds will be possible through this evening.

Outlook...

Monday night-Friday... Conditions expected to remain below
advisory levels through the period, although winds may gust
around 20 knots at times. There is a chance of showers and
thunderstorms each day, which could produce locally higher winds
and waves should they occur.

Rip currents...

the risk for the formation of dangerous rip currents is low
through this evening. An increasing long period swell may
increase the risk to moderate on memorial day.

Phi watches warnings advisories
Pa... None.

Nj... None.

De... None.

Md... None.

Marine... None.

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.
