Synopsis
Low pressure approaches tonight and passes to the north Tuesday.

This intensifying low pressure system will move into the canadian
maritimes Tuesday night into Wednesday night. A weak alberta
clipper passes to the south on Thursday, followed by a low
pressure system passing off the coast Friday night into Saturday.

Near term until 6 am Tuesday morning
Shortwave tracks across il and oh toward the region just ahead
of vigorous shortwave diving out of canada toward the western
great lakes region. At the sfc, two low pressure centers
approach, passing across the great lakes region toward western
ny state by Tuesday morning. A warm front WAA out ahead of the
lows upper shortwaves will result in an increase in clouds, and
precipitation chances increase after midnight.

Cold air initially across the northeast will warm as the night
progresses. Sfc temperatures may initially fall this evening,
then hold steady before rising overnight as south flow begins to
pick up.

At this time, precip looks to hold off until late at night per
most operational models solutions, and many GEFS members. Across
the interior, a few hours of snow is possible, with very low
chances toward the coast for either a wintry mix or plain rain.

Timing and placement will be the key as low levels warm ahead of
the lows.

Short term 6 am Tuesday morning through Tuesday night
Upper trough closes off, as sfc low deepens across ny state and
into new england during this time frame.

Qpf looks light, with lower amounts or even trace amounts near
the coast, and higher totals as you head north across the
interior. Would expect interior portions of southern ct, and the
lower hudson valley of southeast ny to observe higher QPF up to
a 1 4 of an inch liquid equivalent.

Early in the morning, a snow or rain snow mix will quickly give
way to plain rain as WAA continues, and the lower levels of the
atmosphere warm. With increasing southerly flow, temperatures
warm through the 40s, and coastal locations should warm to
around 50. Will lean toward the warmer guidance, and would not
be surprised to see some temps slightly higher than guidance.

Any precip tapers off as the day progresses, and drier air moves
in behind the low front by evening thanks to NW flow. With the
upper low in the vicinity, a few snow showers are possible
overnight, but this should be isolated. Gusty NW flow and caa
will commence.

Temps fall to the upper teens 20s across the region. Quite cold.

Long term Wednesday through Sunday
Wednesday begins with an upper low over the northeast and a
deepening surface low entering SE canada. There could be some snow
showers over eastern LI and SE ct in the morning before the upper
low shifts east and overall lift diminishes. Dry, cold and windy
otherwise. 850mb temperatures will fall to around 15c, but partial
sunshine and a strong downsloping wind should somewhat temper the
cold air mixing down from aloft. Highs expected to range from the
upper 20s well inland to mid 30s for coastal sections. Wind chills
start in the single digits in the morning and average around 20 in
the afternoon. For now it appears that wind gusts should fall short
of advisory levels, but probably not by much, so it's possible that
an advisory would be needed as the event draws closer. Some coastal
spots might even meet criteria based on sustained winds.

Winds subside Wednesday night and low temperatures will average 5-10
degrees below normal. A clipper low is progged to pass south of us
on Thursday. Models show some track and timing differences as well
as available moisture. Snow from this system may however stretch
north into our region, so will introduce low chances for this into
the forecast for southern sections. Like most clippers, this has the
potential for only light accumulations.

The active weather pattern continues on Friday with an upper trough
axis digging into the ohio valley and models showing low pressure
strengthening off the mid-atlantic coast. The trough becomes
negatively tilted Friday night, but not before the low is pushed se
of the 40n 70w benchmark. Upper jet winds streaks are not currently
progged in a position to help expand the pcpn shield NW towards us
as they did with the storm this past weekend. Shortwaves embedded
within the longwave upper trough however may help spread pcpn closer
to us. Looks like this would be an all-snow event with best chances
of snow Friday afternoon and night. Too early to go with anything
higher than chance pops for this potential event.

A high pressure ridge follows for Saturday with dry weather, then
another low moves through the vicinity of the southern great
lakes ohio valley regions on Sunday. Global models disagree on its
evolution and track, but will go with a dry forecast through Sunday.

A better chance of pcpn across the entire region appears to be
Sunday night or Monday as the low shifts east.

Aviation 20z Monday through Saturday
Vfr tonight. A complex area of low pressure passes to the northwest
of the terminals Tuesday.

Cigs fall to MVFR late tonight, mainly after 09z Tuesday in
response to a warm front which pushes north of the area.

With models trending slightly warmer and drier, little if any
snow is expected. However, if precipitation starts a bit
earlier, some wet snow is certainly possible. By 12z any
precipitation should be mainly in the form rain for most
terminals, except kswf, where precipitation could still be snow
or a mix of rain and snow.

Generally westerly winds today becoming light and southerly this
evening. Wind increases Tuesday morning and gusts become more
frequent with speeds around 20 kt.

A cold frontal passage is expected around 16-19z Tuesday and
winds increase dramatically during the afternoon. Potential
gusts of 25-30 kt+ by evening.

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.
