Synopsis
High pressure will dominate through the weekend. A cold front
approaches on Monday and moves through Monday night. High
pressure follows for the midweek period, then a weakening cold
front approaches late in the week.

Near term until 6 am Saturday morning
Ridge remains in place tonight. Few cirrus (mainly clear skies), and
lightening winds will allow temperatures to fall into the 50s and
60s, as radiational cooling will be ideal. Will lean toward cooler
guidance.

However, lows will still average a degree or two above normal.

As for sensible weather, valley fog is possible once again late at
night.

There is a high risk of rip currents at the atlantic ocean beaches
into this evening due to long period easterly swells.

Short term 6 am Saturday morning through Saturday night
Large ridge remains in place. With westerly flow around sfc high
that is centered to our south, and expected temps at the top of the
mixed layer around 16-17c, forecast high temperatures should rise
into the 80s under a good deal of sunshine.

Temperatures Saturday night will once again average above normal,
with a range from the lower 50s interior to mid 60s in nyc,
quite a spread between radiational cooling locations, and urban
heat island effect.

There is a high risk of rip currents at the atlantic ocean beaches
on Saturday. Long period swells lessen as the day progresses, so
conditions may improve late in the day.

Long term Sunday through Friday
High pressure will be centered to our south over the western
atlantic on Sunday. A return SW flow and 850mb temps at around 15c
will allow for highs above normal across the forecast area. Highs
generally in the 80s except for eastern LI and SE ct, particularly
along the coasts.

A longwave trough shifts through the great lakes on Monday and moves
into the northeast Tuesday. This will send a cold front through the
area Monday evening. There will be a chance of showers in the
afternoon into the evening ahead of the front, then chances drop off
during the overnight hours. Have added a slight chance of thunder
for some areas as capes of a few hundred j kg are forecast by some
models, combined with some shortwave and jet streak lift. High
temperatures on Monday will once again reach the 80s for most areas.

High pressure then keeps us dry Tuesday and Wednesday along with
high temperatures closer to normal. A cold front associated with low
pressure tracking through southern canada then approaches on
Thursday. The upper flow is progged to be more zonal than cyclonic,
so the front therefore weakens as it approaches us. Will still go
with a slight chance of showers with this front for Thursday. High
pressure builds back in on Friday with dry weather.

Aviation 20z Friday through Wednesday
High pressure remains across the region through the TAF period.

Vfr.

Winds will be under 10 kts for much of the TAF period. Winds w-sw
this evening near 10 kts but isolated gusts to 15-18kt possible
until sunset for coastal terminals. Winds return to more west to
northwest flow tonight and decrease under 10 kts. Coastal sea
breezes are likely to develop Saturday after 15z, otherwise SW wind
is expected around 10kt.

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.
