Synopsis
Canadian high pressure will build into the region through
Sunday night, then slowly retreat to the northeast through
Wednesday. Meanwhile, a frontal boundary remains stalled well
south of long island for the early to middle part of next week
with waves of low pressure riding along it.

Near term until 6 pm this evening
With canadian high pressure building into the region, clear skies
and light winds have resulted ideal radiational cooling conditions
early this morning with lows falling into the 50s across outlying
areas. Temperatures will rise quickly after sunrise, with afternoon
highs topping out around 80 across the region, which is near normal
for this time of year.

Short term 6 pm this evening through 6 pm Friday
A shortwave rounding the base of the upper trough will cross the
area tonight, resulting in an increase in cloud cover but
little if anything in the way of precipitation. The clouds will
also help limit radiational cooling, resulting in lows ranging
from the mid 50s across outlying areas to the mid 60s in the new
york city metro area.

Clouds will dissipate in the wake of the shortwave, resulting in
another mostly sunny day on Friday. With continued cold air
advection, highs on Friday will be a few degrees cooler than today,
generally in the mid to upper 70s.

Long term Friday night through Wednesday
A mean trough remains over the northeastern and mid-atlantic states
Friday night through Saturday night. While a stray shower with the
region near the base of the trough cannot be completely ruled out
during this time frame, it is far more likely that any given point
in the forecast area remains dry, so have gone with a dry forecast.

Lows Friday night should be 5-10 degrees below normal,
with normally cooler locations falling into the mid 40s to around
50 in response to decent radiational cooling. Highs Saturday should
be around 5 degrees below normal. Lows Saturday night should be a
few degrees warmer than those of Friday night, as passing of the low-
mid level trough axis should cause just enough mixing in the low
levels to limit the low level inversion depth.

Northern stream ridging builds in Sunday-Monday night keeping things
dry.

The forecast is somewhat uncertain Tuesday-Wednesday as there are
varying model solutions in the handling the interactions between
the aforementioned northern stream ridge, an approaching northern
stream shortwave trough coming in behind the ridge, and the remains
of tropical cyclone harvey over the lower mississippi valley. For
now it appears most likely that any coastal low that forms along a
frontal boundary stalled out near the gulf coast sates to off the se
coast will stay far enough south that we should remain dry. However,
it is not outside the realm of reasonable possibilities for the
coastal low to end up farther north than currently forecast. This
bears monitoring as time progresses.

Aviation 09z Thursday through Monday
A weak cold frontal passage will occur late today. High pres
will then build in thru sat.

Vfr thru the TAF period. Light nly flow will back to the SW ahead
of the front today, then veer again to the N in the eve. The
nly flow will continue thru 12z fri.

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.
