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. 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 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/
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. 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 and
finally 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 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.

Lows at night through the long term are pretty consistent, in the
upper 30s to low 30s for a majority of the area.

Aviation /08z Thursday through Monday/
Vfr through the TAF period with a mainly clear sky.

Nw winds 15-20kt with gusts 25kt will slowly diminish overnight.

Gusts may die off for a short period for most terminals, with
the exception of the nyc terminals. Winds will pick up again
for a few hours late morning and early afternoon Thursday, then
likely drop off in the evening as high pressure settles across
the area.

Clouds increase late in the TAF period as low pressure passes north
of the region.

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.
