Synopsis
High pressure builds today, and passes to the east tonight. A
warm front moves across the region Friday. The warm front
north of the region Friday night and Saturday will move back
southwestward Saturday night into Sunday as a back door cold
front. A weak low develops along the front and the low and
front eventually move east of the region by Monday night and
Tuesday of next week. Another cold front approaches for next
Wednesday.

Near term /until 6 pm this evening/
The forecast is on track this morning. Only slight adjustments
were made to temperatures and dewpoints to better match observed
trends.

The center of high pressure builds to our west, and passes to the
south this afternoon. Upper trough tracks further to the east.

A dry, chilly day is expected, with lighter NW winds than what was
observed yesterday. A few gusts are possible in the NW flow, but
winds will diminish this afternoon and back to the west as the high
tracks south.

Temperatures, after a cold start to the day, will rebound through
the 30s, but will peak about 10 degrees below normal, upper 30s to
lower 40s.

Plenty of sunshine is expected.

Short term /6 pm this evening through 6 pm Friday/
Upper ridge to the west flattens tonight and Friday as closed low
moves across the mid section of the country. Surface high pressure
passes east of the area.

A warm front then approaches Friday morning, with a weak shortwave
riding along the top of the ridge, passing across the area Friday.

Winds remain light tonight as they become variable or light s/sw.

With cold airmass in place, temperatures will fall into the 20s
and 30s as high clouds increase. Some locations may radiate
into the teens. Still quite cold.

Increasing moisture riding over the top of the flattening ridge will
approach Friday morning. Light precip associated with warm air
advection is anticipated. Expect a brief period of light
precipitation to push through, with higher coverage NW zones, and
less SE zones per model consensus.

As for ptype, this could be problematic. Depending on when precip
moves in, looks like shortly after 12z, a wintry mix is possible.

Snow, sleet and freezing rain is a good bet, especially away from
the coast. Again, depending on precip onset.

Temps near the coast should be warm enough for plain rain. Qpf
should be under a tenth of an inch, so this is not a big event. But,
slick travel is possible as sfc/road temps may be cold enough for
some light icing.

Long term /Friday night through Wednesday/
Upper levels convey polar jet staying north of the region during
the long term.

Mid levels transition from zonal flow Friday night through Saturday
night to ridging Sunday, which will be followed by an approaching
shortwave on the back end of the ridge. The axis of this trough
moves across on Monday. Behind this shortwave, more quasi-zonal flow
will be established. There will be a larger shortwave approaching
from the northwest for the middle of next week.

At the surface, Friday night through Saturday will be when the
region is in the warm sector. The warm front will be north of the
region. Then, the front will start to shift southwestward, coming
back through the region as a back door cold front Sunday. The front
will stay west of the region and high pressure will stay well east
of the region going through Sunday evening setting up easterly
flow. For late Sunday night, the front will slide back east
with weak low pressure developing along it. The weak low and
front stay near the region Monday with more SE flow developing
ahead of the low and finally these move east of the region
Monday night and Tuesday. Another cold front approaches for the
middle of next week.

Overall, an unsettled weather pattern sets up leading to less
diurnal temperature range as the airmass becomes more cool
maritime from an increasing easterly flow with rounds of light
to perhaps moderate rain at times.

Temperatures are warmest on Saturday with area in the warm sector as
highs are forecast to range from the low 50s to low 60s. Sunday
looks to be the coolest day in the long term with a back door cold
front moving in as highs that day range from the low to mid 40s.

Otherwise the rest of the days feature highs in the upper 40s to
low 50s for most locations. Lows at night through the long term
are pretty consistent, in the upper 30s to low 40s for a
majority of the area.

Aviation /14z Thursday through Monday/
High pressure builds in from the west today, then slides
offshore to the southeast into Friday morning.

Vfr through the TAF period.

Nw-wnw flow with gusts of around 15-20kt at all terminals from
late morning into mid afternoon. Wind gusts should abate by late
afternoon, with winds becoming light and variable at all
terminals this evening. Kjfk could see light ssw-s flow (just
above 5 kt) establish itself by late in the TAF period.

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.
