Synopsis
A warm front moves through the area by early afternoon,
followed by a cold front tonight. High pressure builds late this
week, followed by a cold front Saturday. A cold front will pass
through on Saturday. High pressure builds behind the front.

Near term until 6 pm this evening
Rain showers have been heaviest along the south shore of long
island and offshore which is also where there has been
occasional embedded thunderstorms. The convection has not
become too organized without much of any gusty winds with this
activity. The convection moves across eastern long island and
southeast connecticut mainly before 2pm this afternoon. Other
showers are possible as a cold front approaches later this
afternoon, with coverage isolated to scattered.

No concerns for severe weather at this time due to lack of surface
instability and shear.

Temperatures today will reach the low to mid 80s in the nyc nj
metro and the combination of the higher humidity may make it
feel closer to 90. Elsewhere the temperatures will be in the mid
to upper 70s.

There is a moderate risk of rip current development at the atlantic
ocean beaches today.

Short term 6 pm this evening through 6 pm Wednesday
Forecast soundings indicate significant drying aloft in the
afternoon, so any convective development will be isolated at best.

This chance is further reduced with loss of heating in the evening.

The cold front passage tonight should be dry with no precipitation
forecast. Lows will be in the 60s for much of the region. High
pressure builds toward the area on Wednesday.

There is a moderate risk of rip current development at the
atlantic ocean beaches on Wednesday.

Long term Wednesday night through Monday
With the exception of an upper level disturbance moving across and
possibly sparking an isold TSTM well NW of nyc Wed eve, high
pressure will dominate through the end of the week, with a very warm
but dry air mass remaining in place. Daytime high temps should reach
the upper 80s and lower 90s away from south facing shorelines, a
little above composite gfs ECMWF mos and consistent with both h8
temps +16c and h5-10 thicknesses around 570 dm. With dewpoints in
the lower 60s, apparent temperatures will run very close to air
temperatures.

A closed low dropping SE into eastern canada should drive a cold
front through on sat, with sct showers tstms. With temps still
running on the very warm side, dewpoints increasing to the mid 60s,
and NW flow aloft, would anticipate some of these to be on the
strong side. After fropa, Sat could still be very warm via downslope
nw flow but dry. A return to near seasonable temps not expected
until mon, with highs from the upper 70s to mid 80s.

Aviation 15z Tuesday through Saturday
A low pressure trough shifts through the terminals today with a
cold front moving through this evening into tonight.

Improving to mostly MVFR early this afternoon. An isolated tstm
still possible during the first half of the afternoon. Conds improving
toVFR later in the afternoon.

Light se-s flow at around 10 kt or less bcmg s-sw this
afternoon. Evening winds become NW with the passage of a cold
front.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
