849 pm edt Thu aug 17 2017
A warm front will approach tonight and move north through Friday
morning. A cold front approaches Friday, moving across the
region late Friday night. A frontal system will slowly pass
offshore on Saturday. High pressure will then build in through
the beginning of next week, followed by a midweek cold frontal
Near term until 6 am Friday morning
Primary update this evening was to lower precipitation chances
through much of tonight based on current observational and hi-
resolution model trends. Best chance of any rainfall looks to be
right around rush hour in the morning as the warm front passes
northward. Previous discussion follows.
An area of low pressure will track east across the northern
great lakes tonight. A warm front associated with the system is
expected to approach this evening and lift north through the
local area overnight and into Friday morning. Showers and
possible thunderstorms will spread across the area overnight and
into Friday morning. Temperatures tonight will be in the upper
60s to lower 70s.
There is a moderate risk for the development of rip currents at
the ocean beaches today.
Short term 6 am Friday morning through Friday night
As a warm front moves north a strong southerly flow will usher
in behind, bringing an influx of moisture across the area.
Dewpoint will rise back into the 70s across the region along
with instability resulting in thunderstorms and heavy rain to
develop. There may be a break in the precipitation for a brief
time once the warm front lifts north, and until the cold front
nears later in the day. Storms will weaken and move into long
island and southern connecticut by Friday night.
Temperatures on Friday will be in the upper 70s to lower 80s
with lows in the upper 60s to lower 70s.
Long term Saturday through Thursday |
The frontal boundary sfc trof will slowly slide offshore on sat.
Trends will need to be monitored for a slowing of this feature, as
the main upr trof which will force it ewd is still progged to be
over oh at 18z sat. The slower the boundary exits, the slower shwrs
and especially clouds will exit. Based on the 12z data, areas along
and W of the hudson dry, with the rest of the area low chances for
pcpn. Dry weather Sat ngt thru Mon ngt with high pres progged to
12z GFS timeheights indicate sunny skies on Mon with perhaps some
fair wx cu, particularly along the sea breeze front.
Chances for shwrs and tstms Tue thru Wed ahead of a cold frontal
passage. Best chances are Wed closest to the front attm, so as the
event draws closer pops may be eliminated for tue.
A blend of the guidance and 2m data was used for temps thru the
period. The numbers will generally be abv average until the fropa

A warm front approaches from the southwest tonight. A cold front
will approach from late Friday.
Vfr early tonight before deteriorating conditions late tonight into

sector after the warm fropa, may be too optimistic in the nyc
Friday will be very unsettled with the threat of showers and
scattered thunderstorms in the morning and then again with the
approaching cold front late in the afternoon. Gusty winds and
MVFR ifr are possible with any heavier shower or thunderstorm.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
