What's New / NOTES
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Synopsis
Strong high pressure continues to pull away from the new england
coast. A slow moving frontal system approaches late Monday night,
impacting the region Tuesday into early Wednesday with strong
winds gusts and potentially heavy rain. The frontal system
slowly moves east of the area Wednesday night with brief high
pressure following through the end of the week. A cold front
then merges with a developing coastal low Saturday night into
Monday.

Near term until 6 am Tuesday morning
With upper level ridge passage clouds will dominate beginning
tonight. Complex frontal system over the ohio and tennessee
valleys will draw closer tonight. With well established moist
southerly flow ahead of the front expect areas of patchy fog
along with drizzle in some locations. Lift is shallow and weak
overnight, except after 6z in far western zones when showers
begin to move in.

Temperatures remain well above normal tonight due to clouds and
warm air advection. A model blend was used for temperatures.

Short term 6 am Tuesday morning through Tuesday night
Nwp guidance is in good agreement through Tue night.

A vigorous pac shortwave will continue to dig the longwave
trough and gets to the gulf coast by Tuesday night. The first
feature that will drive surface weather is a low level jet with
high pws for this time of year. This will result in periods of
rain, with embedded heavier showers and gusty winds. Some cape
in model profiles suggest few rumbles of thunder on Tuesday.

The second feature which will drive any convective rain will be
the approaching frontal system for Tuesday night, with models
indicating the best potential for widespread rainfall amounts
above 2 inches to be east of new york city. With amplification
of the longwave trough the frontal system is indicated by nwp
models to slow and track very slowly across the region Tue night
in the longitudinally oriented steering flow. Trend with this
update has been to continue to slow the system's progression
through Tue night which would only serve to increase rainfall
amounts for eastern sections.

The following potential hazards Tue tue night:
heavy rain: the slow movement of the front, deep lift, weak
instability, and interaction with an increasingly moist and
tropical airmass (+3 to 4 std) signal potential for multiple
bands of heavy rain as weak waves lift north along the front.

The higher resolution WRF based models continue to indicate the
potential for a localized swath of 3-5 inches. This looks to be
a credible threat based on synoptic pattern, but location timing
is very much uncertain based on front and frontal wave timing
and location. Would also like to see additional support of this
in some other hi-res models. See hydrology section for
associated flooding threat.

Strong winds: a wind advisory is in effect for most of our ct
zones, along with coastal zones in ny. A 45-55 kt 925 hpa llj
moves overhead Tuesday into Tue night. The GFS bufkit soundings
indicating a 12 hr period of southerly winds gusts of 30 to 40
mph, with potential for any low topped convective line S ahead
of the cold front being able to drag down localized 45-55 mph
wind gusts to the surface. SPC has our area in a slight risk
with damaging wind gusts the main threat. Not seeing the best
low level lapse rates and 0-1 km shear, so not all that bullish
on tornadic activity, with later shifts needing to further
inspect.

Long term Wednesday through Monday
A slow moving upper trough will maintain significant moisture
advection in broad, nearly unidirectional southerly flow into at
least the early portion of Wednesday. Primary update to the
extended forecast was to slow the departure of the surface front
and associated precipitation, mainly across portions of
connecticut and long island. Ensemble forecasts still suggest
some uncertainty with regards to end time of precipitation,
though in general rates should taper off from west to east
through the evening. Depending on how quickly rainfall ends,
adequate mixing in the afternoon and evening with modest west-
northwest flow may support a few gusts.

High pressure then builds through the remainder of the week with a
return to more seasonable temperatures and humidity, though with
some subtle moderation and warming to the air mass as the week
progresses.

Meanwhile, a long wave upper trough will develop and slowly push
eastward, allowing strong moisture advection again into Sunday. The
increasing difluence aloft will aid in the development of a
coastal low, which is then expected to merge with the frontal
system, increasing chances of rain across the area. At the
moment, the exact timing, accumulations and rates of any
precipitation remain uncertain but the system will continue to
be monitored.

Aviation 22z Monday through Saturday
A slow moving cold front will approach the region tonight but
not pass through the region until Tuesday night.

MVFR returns this evening with patchy drizzle developing.

Showers become more widespread from west to east after 06z with
MVFR ifr cigs.

With the approach of a low level jet, showers with embedded
thunder are likely Tuesday. The rain will be heavy at times
accompanied by strong wind gusts, especially near the coast.

Compression and low level wind shear are likely, mainly ssw
45-55kt@2kft for coastal terminals.

Se winds increasing near 15kt with gusts to 25kt possible this
evening, especially near the coast (nyc and LI terminals). Wind
increases tonight with gusts becoming more frequent around 25kt.

Some gusts 30-40kt possible after 12z Tuesday, especially the nyc
terminals.

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.
