Synopsis
High pressure builds in from the north today, however a weak low
pressure trough will be passing to the south at the same time. High
pressure then weakens on Friday as it moves offshore and another
weak area of low pressure shifts through near us. A cold front moves
through Friday night as high pressure builds to the north. A
warm front approaches Sunday, and a cold front passes late
Sunday. High pressure builds early next week.

Near term until 6 pm this evening
High pressure center shifts through southern quebec today with
ridging into the tri-state area today. At the same time, a weak
trough of low pressure will be shifting east along a stalled
boundary to our south. Additionally, 850-700 mb shortwave energy
will provide some lift, and with rh values in this layer remaining
high on a SW flow, it'll be a cloudy day with some light to moderate
pcpn. Higher overall pops will be this afternoon, coinciding with
the deepest moisture and lift.

Pcpn types across the area will be tricky across most of the area.

Nam rap hrrr rgem continue to be on the warmer side regarding
temperatures in a warm-nose aloft at 800-700 mb while the global
models are colder. The strength of this warm nose in combination of
lower-level sub-freezing temperatures, including some freezing
surface temps late today, will have implications on pcpn types.

Prefer warmer temps aloft with the SW flow, and will lean towards
nam in this regard, but it might be too warm aloft. High pressure to
the north and nne surface winds will help low-level cold air
drainage damming across ct and the lower hudson valley. Will
therefore lean towards NAM for lower-level temps and use its 2-meter
temps for the surface at it tends to perform better with thermal
profiles in this type of setup, especially within 24 hours.

No winter weather headlines will be issued at this time. Thinking is
that there is a limited opportunity for freezing rain today. The
chances for this would be north of the city this afternoon, however
thermal profiles would more likely be supporting sleet for these
areas during this period. Sleet accumulations expected to be limited
to under an inch. Will address the freezing rain and sleet
potential with an sps across the northern zones. Rain is
otherwise expected elsewhere, but even a chance of sleet exists
as far south as the city, long island and NE nj by late.

High temperatures for the calendar day will be from the pre-dawn
hours. Expect temperatures to fall into the 30s everywhere by early
afternoon.

Short term 6 pm this evening through 6 pm Friday
Models from 24 hours ago have trended drier along with stronger
ridging into the region tonight. Pcpn ends early this evening with
dry weather most of the night. Another wave of low pressure passes
nearby. Pcpn then spreads east to west Friday morning, with all
areas seeing pcpn during the afternoon. Thermal profiles support
rain for the most part, however western orange county can pick up a
couple hours of freezing rain. Right now do not have the confidence
and coverage to go with an advisory, and will let subsequent shifts
assess trends and issue any as needed.

Long term Friday night through Wednesday
Aloft, fast westerly flow, with embedded weak shortwaves ride over
the top of the southern ridge initially. Downstream trough out west
tracks across the mid section of the country Saturday moving
southwest to northeast across the great lakes region. Ahead of this,
heights rise along the eastern seaboard. Trough passes early next
week with ridging Tuesday and Wednesday ahead of next trough out
west.

At the surface, models agree in a cold front sagging just south
Friday night into Saturday as high pressure builds to the north.

This will result in a brief period of dry weather later Friday night
into Saturday.

Then the front begins to move back to the north as a warm front
Saturday night into Sunday. It appears that a triple point low
tracks across the area, with occluded front to the north extending
from the parent low that tracks to the north of the great lakes
region. The cold front passes Sunday night.

High pressure then builds Monday through Wednesday, with perhaps a
weak trough passing late Tuesday.

Any lingering rain Friday evening ends briefly, then next round of
rain moves back in late Saturday from southwest to northeast. The
bulk of the rain occurs Saturday night through Sunday morning. Rain
tapers off later Sunday behind the triple point low and front. Warm
enough for plain rain everywhere.

Dry weather is expected thereafter.

Temperatures remain above normal, but not as warm as the past couple
of days.

Aviation 10z Thursday through Monday
A weak wave of low pressure tracks south of the terminals today
along a stalled cold front.

Vfr conditions this morning will gradually fall to MVFR and then
likely ifr this afternoon. A few, brief showers cannot be ruled out
through sunrise before more widespread precipitation develops from
west to east through the rest of the morning and into the afternoon.

Precipitation type will be mostly rain at new york city and long
island terminals. There is a chance the rain could mix with some
sleet late this afternoon early evening.

For the lower hudson valley and southern connecticut terminals, rain
will mix with sleet late this morning and early afternoon. There is
also a chance of freezing rain late this afternoon. Less than an
inch of sleet accumulation is possible.

Ne winds will gust 15-20 kt today. NE winds will gradually diminish
this evening and tonight.

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.
