Synopsis
High pressure passes to the south today, and a cold front
approaches tonight. The cold front moves through Monday
morning, followed by high pressure building in from the north.

The high pressure settles over the region Wednesday into
Thursday, then slowly retreats offshore late in the week. A
frontal system will approach during next weekend.

Near term until 6 pm this evening
Mid upper level closed low over the central plains opens weakens
as it traverses toward the ohio valley. Weak shortwave ridging
builds over the area behind exiting trough, and sfc high
pressure builds to the south.

Winds will back to the W SW as the day progresses. With a
pressure gradient remaining in place, these winds will provide a
slight breeze, but remain much weaker than what was observed
yesterday.

Waa will allow for temperatures to rise into the 50s, especially
away from south facing shores. A few locations where the wind
fetch remains over land could approach 60 degrees.

Plenty of sunshine this morning will give way to high clouds in
the afternoon, filtering the Sun a bit.

Short term 6 pm this evening through Tuesday
Weakened shortwave over the lower ohio valley moves southeast
toward the carolinas by Monday night. Meanwhile, upper trough
extending across southeast canada results in a slight lowering
of heights across new england. This will push a cold front
south of the area late tonight early Monday morning.

Clouds will lower tonight, but 00z model suite still suggests
plenty of dry air below 6 kft. Most model solutions remain dry
as front, trough get sheared out, but cannot rule out a passing
light shower, sprinkle as the front moves through. If precip
occurs, the higher elevations over the interior could see a few
snow flakes.

With the clouds, and a light west southwest wind, temperatures
will fall only into the mid 30s to lower 40s.

Once the front passes, canadian high pressure builds across the
great lakes region. CAA ensues, and temps rise to around 50
Monday afternoon as skies clear out, then fall into the 20s
Monday night under clear skies. On Tuesday, high temperatures
remain in the 40s, several degrees below normal.

Long term Tuesday night through Saturday
A polar high will settle over the region Tuesday night into
Wednesday. This will provide an early spring chill for Tuesday night
into Wednesday morning with low temperatures falling into the 20s
widespread across the more rural areas, to around freezing in urban
locations. The core of this cold airmass begins ejecting northeast
out over the northern atlantic during Wednesday as temperatures
start to moderate with upper level ridging working in from the
plains and midwest. After a chilly start to Thursday due to light
winds and ideal radiational cooling conditions, temperatures really
start to move up during the day on Thursday. This is when locations
away from the ocean begin to flirt with 60, or at least upper 50s.

By late Thursday into Friday 500 dm heights begin to climb above 570
dm with a deeper SW flow starting to get established. Therefore, by
Friday as long as there is some westerly component to the low level
winds surface temperatures should climb into the 60s inland, with
perhaps some locations getting near 70. Will have to keep an eye out
for some afternoon stratus coming in off the ocean for late in the
week with ocean temperatures still well down into the 40s.

Towards late Friday and into the weekend most of the global model
suites are showing the ridging hanging tough along the eastern
seaboard, with the ECMWF being more of an outlier. The ecmwf
attempts to bring a frontal system closer to the region by late
Friday and Friday night, with the gfs, icon, navgem, and gem not
budging as of yet. Decided to put less weight into the ecmwf, but
not discount it entirely. Therefore looking for dry conditions
through Friday, and then start to introduce slight chance pops
during Saturday.

Aviation 07z Sunday through Thursday
High pressure builds in from the west overnight and then passes
to the south later today.

Vfr. Gusty NW winds have diminished with the winds lighter going
into the early morning. The winds also become more westerly
into the early morning. Later today the winds will become
southwesterly and increase to 10 to 15 kt, with a few gusts to
around 20 kt possible by the early afternoon. The winds will
then diminish again during Sunday evening.

Outlook for 00z Monday through Thursday
Sunday night Vfr.

Monday MVFR possible in the morning with the chance of light
rain with a cold frontal passage.VFR conditions expected for
the afternoon. Winds becoming N around 10 kt.

Tuesday through Thursday Vfr.

Marine
Sca will remain in effect for the ocean waters east of fire
island inlet. Winds have diminished, but should increase again
later today as they back to the west southwest. A westerly fetch
will also allow seas to build to 5 ft again for these eastern
waters.

Otherwise, sub SCA conditions are expected today and tonight for
the non ocean waters, and western ocean waters west of fire
island inlet.

A cold front approaches tonight, and passes to the south Monday.

Northerly winds increase behind the front late Monday and Monday
night, then diminish as high pressure builds toward the waters
Tuesday.

With high pressure settling over the coastal waters during Tuesday
night and into Wednesday conditions will be relatively tranquil with
the winds on either side of 10 kts and low seas. By later Thursday
and into Friday the high will push further offshore resulting in a
light east to southeast wind with sub SCA conditions continuing.

Hydrology
No hydrologic impacts are anticipated for the next 7 days.

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.
