Synopsis
Low pressure tracks through the tri-state region overnight
and off the new england coast Friday into Friday night. High
pressure builds down from southeastern canada for the weekend.

This high then retreats to the northeast early next week as weak
low pressure tracks to the south. A cold front approaches from
the west on Tuesday, then crosses the area Tuesday night. This
front then stalls out nearby as high pressure builds in from the
southwest, producing potentially unsettled weather for the
middle of next week.

Near term until 6 am this morning
Both the upper and surface lows will move across the area early
this morning with widespread showers and embedded thunderstorms.

Adjustments were made to account for higher rain chances as far
west as the lower hudson valley.

Brief heavy downpours are expected overnight with minor,
nuisance flooding possible. Conditions start to dry out toward
daybreak form SW to NE as the upper low lifts NE of the region.

Surface low pressure will move along or near the long island coast
overnight so winds will not be as strong. The warm front may
even briefly move across portions of eastern long island before
the low lifts to the north and east.

Short term 6 am this morning through 6 pm Saturday
Upper low and surface low become vertically stacked as they move off
the new england coast on Friday. Wrap around showers and possible
thunder linger for a few hours around day break across eastern
connecticut and the forks of long island. Otherwise, clouds
will be slow to clear as moisture lingers below 10 kft. Nw
downsloping flow should help to create some breaks in the
clouds, especially across the western half of the area. These
breaks will help boost temperatures into the 70s, with cooler
readings in the middle to upper 60s further east where clouds
linger longest.

Model soundings indicate some instability between about 5 and 10
kft, so clouds may fill back in with any breaks. There is also the
possibility of a few iso-sct showers. No thunder is forecast since
the instability does not look to get much above -5c with heights
building aloft behind the upper low.

Weak ridging passes Friday night as high pressure moves into the
region from the west. Lingering moisture will keep skies partly to
mostly cloudy with lows near normal values.

Long term Saturday night through Thursday
The region is in between two shortwaves passing to the north and
south Saturday and Saturday night, so with most significant forcing
outside of the area, have at most slight chance pops in this time
frame, with temperatures near to slightly above normal.

Onshore flow will dominate from Sunday through Monday.

The result will be mainly gray sky conditions with spotty light rain
or drizzle mainly over higher elevations mainly to the N W of nyc
from Sunday into Sunday night as a northern stream shortwave ridge
crosses the area. A 700-500 hpa shortwave approaches late Sunday
night and crosses the area on Monday, making for a more widespread
rain over the region then.

With the onshore flow damming high, have undercut guidance by mixing
in NAM and ECMWF 2-meter temperatures. Highs will run 5-10 degrees
below normal Sunday and Monday and lows a few degrees above normal
Sunday night (due to reduced diurnal range).

A broad closed low slow tracks from ontario into western quebec from
Monday night through Thursday, with shortwaves rotating around the
base of the low from time to time. The timing of these shortwaves is
somewhat difficult this far out, but for now it appears that most
energy will be focused mainly to the N of the region. As a result,
there is a chance of isolated to scattered showers - mainly over
northern portions of the tri-state. Also, cannot rule out an
isolated rumble of thunder Tuesday Tuesday night with the passage of
a surface cold front.

Temperatures Tuesday-Thursday should run near to slightly above
normal.

Aviation 06z Friday through Tuesday
Low pres passes thru the region early this mrng, then into the
gulf of me this aftn.

Ifr lifr conds improving to MVFR at times with shra tstms. Tstm
chances drop off thru 08z with a return to prevailing ifr lifr
for the rest of the night.

Flow will be vrb with the passage of the low, then NW flow
develops as the storm tracks away from the area.

Improvement back toVFR by this afternoon. W-nw gusts 20-25 kt.

Winds generally south of 310 magnetic. Shra possible.

Outlook for 06z Saturday through Tuesday
Late tonight Vfr.

Saturday Vfr.

Saturday night-Monday MVFR ifr possible in showers. E se
winds.

Tuesday Improving toVFR. S SE winds.

Marine
Updated weather and probabilities for showers and scattered
thunderstorms early this evening across the far eastern ocean
waters and into the eastern long island sound.

With nearshore wind gusts, and across the waters, below 25 kt
the small craft advisory for the bays and new york harbor and
long island sound was allowed to expire. Easterly winds will
gradually weaken into this evening as the pressure gradient
relaxes. Seas on the ocean will remain at small craft levels
through Friday and the small craft was converted to a hazardous
seas small craft. These seas will gradually subside Friday night
with sub-sca conditions elsewhere.

A light pressure gradient over the region Saturday-Tuesday should
limit winds to 10 kt or less. Given the absence of any significant
swell, in addition, conditions should be below small craft advisory
conditions over the waters around long island Saturday-Tuesday.

Hydrology
An additional 0.50 to 1.0 inches of rain is forecast through
Friday morning. The highest amounts will likely occur across
eastern connecticut and eastern long island. Locally higher
amounts are possible where thunderstorms occur overnight. Minor
urban and poor drainage flooding is possible.

It should then be mainly dry Friday night-Sunday.

Another round of rain is possible from Sunday night into late
Monday. At this time, it is to soon to specify, what, if any,
hydrologic impact will be experienced from this system.

Tides coastal flooding
A coastal flood warning continues for moderate flooding
potential for the south shore back bay locations of nassau
county for tonight, and advisories are in place for minor
flooding potential for areas adjacent to western long island
sound, ny harbor, and the south shore back bays of the western
long island. Minor flood thresholds could briefly be touched
along the eastern bays of LI and SE ct.

How quickly easterly winds begin to weaken this
evening will be key to the potential for seeing widespread
versus localized moderate coastal flooding along the southern
bays of western li. Less than 1 2 ft of surge is needed in many
places to reach minor flood thresholds.

The threat for minor coastal flooding is likely to continue during
the nighttime high tides for the southern bays of western LI nyc
through the memorial day weekend. While along western long island
sound, lower ny harbor, and eastern great south bay... Minor coastal
flooding is possible at those times.

Beach erosion is expected with the prolonged easterly
sweep... But the potential for dune erosion looks to be low and
localized.

Okx watches warnings advisories
Ct... None.

Ny... None.

Nj... None.

Marine... Small craft advisory for hazardous seas until 6 pm edt this
evening for anz350-353-355.

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.
