What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
High pressure will dominate the weather through Saturday. A
cold front pushes south of the area and remains nearly
stationary through memorial day. Another cold front follows on
Tuesday with high pressure building in behind.

Near term until 6 am Thursday morning
An upper level trough moves further offshore tonight. Heights
rise as ridging approaches and surface high pressure builds
towards the region tonight. Expect mostly clear skies and light
winds tonight. Overnight lows will fall into the 50s and lower
60s. A mav met ecs blend for overnight low were used.

Short term 6 am Thursday morning through Friday
Surface high pressure builds into the region on Thursday, then
remains in place through Friday. Expect mostly sunny skies both
Thursday and Friday, with mostly clear skies Thursday night.

Temperatures on Thursday will climb into the 70s and lower 80s,
temperatures on Friday will be warmer with highs in the upper 70s
and 80s. The only exception will be right along the immediate
coastline, where temperatures will hold in the lower 70s. Thursday
night, lows fall into the 50s and lower 60s.

Long term Friday night through Wednesday
Anchored high pressure off the mid-atlantic coast will lead to a
continued southwest flow ushering in a more humid airmass on
Saturday. Temperatures are expected to be in the upper 80s under a
mostly sunny sky. Temperatures in and around nyc may even hit the 90
degree mark. South facing shores of long island and ct will be about
5-10 degrees cooler due to the southerly flow off the water.

Sunday becomes more complex as a cold front gets pushed to the south
as northern stream high pressure moves into eastern canada. The
front may remain south of the area into memorial day which will keep
an unsettled pattern in place. However, it should be noted there is
still a large amount of uncertainty on whether the front retreats
back into the area or remains to the south. The placement of the
front will ultimately determine temperatures and the rain threat
Sunday into memorial day. Have kept chance pops in the forecast
through Monday afternoon. Easterly flow will keep clouds and cooler
temperatures in the forecast with highs on Sunday and Monday only in
the upper 60s to mid 70s.

Another cold front is expected to swing through on Tuesday with
canadian high pressure following behind it. Temperatures return to
near seasonable to a few degrees above.

Aviation 00z Thursday through Monday
High pressure builds tonight and Thursday.

Vfr conditions are expected through the TAF period with few
clouds to contend with.

Light NW winds are forecast tonight. NW winds Thursday morning
will shift around to local seabreezes in the afternoon, except
kswf.

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.
