Synopsis for the tidal potomac and md portion of the chesapeake bay.. A weak boundary will remain stalled out near the waters through Monday. The front will then lift back north by Tuesday as high pressure off the southeastern united states coast regains control through the middle of the week. A weak cold front will stall out near the waters late in the week.

Synopsis
A cold front will cross our region overnight, then high pressure
builds to our north Monday and Monday night. This high builds
offshore early Tuesday, while a warm front lifts across our area.

This front may stall through Wednesday while a couple of low
pressure systems move eastward along it. This front then 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
As of 830 pm, an update has been sent to include severe
thunderstorm watch #258 for our maryland and delaware zones
which GOES until 1 am. Main threat is locally damaging winds and
some hail. Some initial training may result in locally very
heavy rain.

A mid level impulse is moving across central pennsylvania as of this
writing near a surface cold front. It is this feature that is aiding
in large scale forcing and therefore an increase in showers and some
thunderstorms has occurred. This looks to move across portions of
the northern zones, therefore the pops were increased quite a bit
for awhile this evening. In addition, a convectively generated
boundary looks to be draped across far southern new jersey westward
and new convection has rapidly developed along it as some better
ascent has arrived. While convective coverage has been rather sparse
overall, some increase in deeper convection is expected especially
across the far southern areas given the instability and shear
parameters.

Any stronger convective cores that are sustained will have the
potential to produce locally strong to damaging winds especially
given some dry air aloft leading to a downburst potential. Some hail
is possible, however severe hail would be limited to any isolated
robust sustained core. The severe threat looks to be mostly for
maryland and delaware and perhaps into far southern new jersey. It
is here where some enhancement could take place by late evening from
the convective complex now in the eastern ohio and west virginia
areas.

Once the cold front clears the area overnight, some drier air will
begin to advect in from the northwest. Plenty of mid to high level
clouds streaming across the area this evening, some of which is
convective cloud debris, will thin out late tonight behind the cold
front.

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 01z Monday through Friday
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.

Tonight... Some showers and thunderstorms around through about
midnight, with greatest coverage possible near abe and rdg then near
and south from about ilg to acy. Local and brief MVFR ifr conditions
(especially visibility) will occur with any heavier shower or
thunderstorm. Otherwise,VFR. Westerly winds mainly 5-10 knots,
becoming all light northerly overnight.

Monday...VFR. North winds 5-10 knots, becoming locally west and
southwest later in the afternoon. A sea breeze at acy and miv will
result in a wind shift to east to southeast.

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
criteria through memorial day. Some thunderstorms with gusty winds
will be possible this evening mainly south of atlantic city.

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 increases to
moderate on Monday. A long period swell (around 10 seconds) combined
with some increase in the wind as it turns onshore, enhancing a sea
breeze some, is expected to result in an elevated rip current risk
on memorial day especially in the afternoon.

Phi watches warnings advisories
Pa... None.

Nj... None.

De... None.

Md... None.

Marine... None.
