Synopsis
A low pressure system tracks southeast of long island this
morning with high pressure briefly building in this afternoon
and evening. A slow moving low pressure system affects the area
Thursday into Friday before weak high pressure returns again for
Saturday. Another frontal system will then impact the area for
the latter half of the holiday weekend.

Near term until 6 pm this evening
Areas of light rain falling from a mid level cloud deck will
begin to dissipate in coverage the next couple of hours as low
pressure passes to the south and east.

With a broad upper low to the west, expect cloudy conditions to
continue through the afternoon despite precipitation ending
from west to east. In combination with cloud cover, an onshore
component towards the coast will keep temperatures a few degrees
below climatological normals.

Short term 6 pm this evening through 6 pm Thursday
Continued cloud cover ahead of the broad upper low to the west
will keep temperatures overnight closer to normal. Rainfall will
increase from southwest to northeast by morning as the upper low
and a slowly deepening surface low move into the area. An
extended period of southwest flow will continue to advect gulf
moisture northward, leading to possibly moderate rain at times
through the day. As the warm front lifts through the area by
afternoon, elevated instability may support a slight chance of
thunderstorms, though no severe weather is expected at this
time.

As the surface low deepens, the tightening pressure gradient
will lead to strengthening onshore flow, which will keep
temperatures well below normal and also lead to coastal impacts
with above normal tides. See tides coastal flooding for
associated impacts.

Long term Thursday night through Tuesday
An unsettled weather pattern continues through this period as an
upper low lifts out of the northeast on Friday, while another
another drops into the midwest and great lakes states over the
weekend. Upper level ridging between the two systems briefly
builds across the area for the first half of the weekend.

Models are in good overall agreement in taking surface low
pressure over the mid atlantic states Thursday night south and
east of the area and then into the gulf of maine on Friday.

Showers and isolated thunderstorms Thursday night will taper off
on Friday with lingering clouds and showers through much of the
day as deep-layered cyclonic flow remains across the region
behind the departing low.

Conditions will then briefly dry out Friday night into Saturday
as both ridging aloft and at the surface translates east across
the area. Things get a little more tricky heading in Sunday as
another frontal system approaches the area. There are
differences amongst the global models, in particular with the
ecmwf and ggem, as both more aggressive with a frontal wave
ejecting east out ahead of the main frontal system. However, the
00z ECMWF has trended toward the gfs, with a late day warm
frontal passage on Sunday, followed by a weak cold frontal
passage late Monday. There remains some uncertainty with the
timing of warm advection rainfall Sunday into Sunday night. It
could possibly hold off until late in the day. Scattered
convection is then forecast for memorial day along and ahead of
the cold front. Conditions briefly dry out Monday night into
Tuesday before the upper trough and another cold front approach
Tuesday night.

Temperatures during the period will be near seasonable levels.

Aviation 11z Wednesday through Sunday
Low pressure passes south of long island this morning. Weak
high pressure briefly builds in behind the low this afternoon.

Another, deeper, low pressure system then approaches from the
west late tonight and Thursday.

Vfr conditions are expected through 06z. Some light rain,
falling out of a mid-deck, can be expected through 15-16z.

Ceilings fall belowVFR late after 06z tonight as the next low
pressure system approaches. Conditions fall to ifr or less
in rain towards 12z.

Light and variable winds become northeasterly less than 10 kt
this morning. Winds then become easterly late in the day as the
next low approaches. There may be a brief period of light
northerly winds 17z to 20z.

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.
