Synopsis
High pressure slides into the atlantic today into tonight.

Meanwhile, strong low pressure moves into southeast canada. A
cold front will approach the region late tonight and move
across the region on Saturday. The cold front moves east of the
region Saturday night. Strong high pressure builds west of the
region for the second half of the weekend, building into the
local area Sunday night into Monday. This high will shift off
the mid atlantic coast on Monday followed by a weak clipper like
system tracking through new england on Tuesday. High pressure
then returns for mid week.

Near term until 6 pm this evening
Minor adjustments were made to temperatures, dewpoints, and
frost coverage. Frost will melt with rising temperatures this
morning. Coldest locations are the more interior places
currently. Frost advisory and freeze warnings expire at 9am.

Quasi-zonal mid level flow with surface flow becoming more
southwesterly today in response to a departing area of high
pressure. The high pressure will be moving more into the
atlantic. The setup here with veering wind profiles and
vertical mixing between 950 and 900mb, will give a mild day
relative to the previous day as warmer air advects into the
region. Highs are forecast to reach the upper 50s to lower 60s,
about a few degrees below normal though.

Weather remains dry today with high pressure still close enough
to provide subsidence to keep clouds minimal.

Short term 6 pm this evening through Sunday night
High pressure will be sliding well into the atlantic tonight
with strong low pressure at the surface moving into southeast
canada. This will be accompanied aloft by a longer wavelength
trough moving southeast into the great lakes. An associated cold
front will be approaching late tonight.

Persistent SW flow continues and will be gusty at times. In
addition the encroaching low pressure will bring an increase in
clouds. This will keep temperatures from decreasing too much.

Lows are forecast in the upper 40s to mid 50s. The more
unsettled pattern developing here with the approaching cold
front will bring an increase in precipitation chances which will
be rain showers, mainly overnight.

For the weekend, the cold front moves across the region
Saturday, which will be followed by strong high pressure
building west of the region Saturday night. A few showers will
be possible Saturday and Saturday night with the very cold pool
aloft and trough moving in. The high pressure area slowly makes
its way closer to the local region through the remainder of the
weekend. Aloft, the large longwave trough moves in Saturday and
Saturday night. The trough exits Sunday into Sunday night.

Colder air arrives starting Saturday night and through the rest
of the weekend on gusty NW flow. Highs forecast on Sunday are
in the mid 40s to near 50. There are below freezing temperatures
in the forecast for Sunday night across much of the interior.

Long term Monday through Thursday
Zonal flow briefly developing Mon ahead of the next shortwave
tue. This is where solutions diverge in the global models. The
gfs is more amplified and more progressive with building heights
for the middle of next week while the ECMWF is broader at h5
with another shortwave diving down from central canada for thu.

Dry and unseasonably cool weather is forecast for the remainder
of the period, although pops on Tue may increase in subsequent
forecast packages if there is a bit more moisture for a clipper
like system to work with in southern new england.

Aviation 12z Friday through Tuesday
High pressure settles to the south and east of the terminals
through this evening. A cold front approaches tonight into
Saturday morning.

MainlyVFR through the TAF period. There is a chance of showers
tonight into Saturday morning that could briefly lower
conditions to MVFR.

Sw winds will increase through the day with gusts 20-25 kt
this afternoon. Gusts may weaken or briefly end this evening,
but a gusty SW flow returns overnight into Saturday morning,
especially at city terminals and the coast.

Ny metro enhanced aviation weather support...

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.
