Synopsis
Low pressure moves offshore today as high pressure builds from
southeast canada. A cold front approaches Tuesday and moves across
the region Tuesday night. High pressure will follow for Wednesday
and Thursday, then another cold front will pass through on
Friday. High pressure on Saturday and early Sunday should give
way to another low pressure system later Sunday.

Near term until 6 pm this evening
Deeper moisture continues to work its way to the east early this
morning as low pressure passes to our south. While the middle and
upper levels are drying out, the low levels remain saturated. Some
patchy fog is possible, especially across the interior through
around day break.

Otherwise, surface high pressure builds from southeast canada along
with ridging aloft. Lingering low clouds will clear this morning
with mostly sunny skies expected for the remainder of the day. High
temperatures will be a few degrees above normal in the lower to
middle 60s.

Short term 6 pm this evening through Tuesday night
Ridging at the surface will remain in place tonight, but the upper
level ridge axis slides offshore by daybreak Tuesday. SW flow aloft
along with some low level warm advection should help increase
clouds, especially after midnight. Low temperatures fall into the
lower and middle 40s inland to the upper 40s and low 50s near the
coast. It appears temperatures may fall quickest early in the night
and then may fall slower or level off as clouds increase after
midnight.

An approaching middle and upper level trough on Tuesday will send a
cold front towards the area. The trend in the model guidance has
been to slow the timing of the front and associated rain until
Tuesday night. The daytime hours on Tuesday should remain mostly dry
with just a chance of light rain due to weak lift from low level
warm advection. Forecast soundings indicate saturation in the
lowest 5 kft with a fairly large layer of middle level dry air.

This middle level dry layer does not saturate until the actual
frontal system and stronger middle level dynamics near Tuesday
night.

The consensus of the latest guidance has the front entering western
zones after 00z Wednesday and then slowly working its way east
through the rest of the night. The GFS appears to be struggling with
the placement of the dynamics and where a wave of low pressure may
exist along the front. Have sided with the better consistency of the
nam and ecmwf. While the strongest dynamics may pass just to our n,
there should be a band of rain along and ahead of the front that
lifts through the region. The front and rain should be moving
offshore by early Wednesday morning. Rainfall amounts of 0.50 to
0.75 inches are possible across the interior with 0.25 to 0.50
inches elsewhere. Locally higher amounts are possible if any heavier
downpours develop. Instability is weak and have opted to leave
mention of thunder out of the forecast.

Long term Wednesday through Sunday
High pressure builds into the region on Wednesday behind a departing
cold front, and is expected to dominate through most of Friday. A
cold front then approaches daytime Friday and passes across the area
Friday night that could bring a chance of showers mainly inland.

Another area of low pressure approaches late in the weekend or early
next week. There are some timing issues with respect to the 00z gfs
and ECMWF models. For now, will limit pops to just chance with an
increasing chance of rain chances on Sunday into Sunday night.

Temperatures should be at or slightly above normal Wednesday
through Friday. Slightly cooler than normal temperatures are
then likely for next weekend, behind the cold front.

Aviation 07z Monday through Friday
High pressure builds into the region today.

Mostly MVFR to start, then improving toVFR across the
terminals as the morning push progresses. RemainingVFR into the
evening.

Ne-n winds averaging around 10kt. Some gusts 15-20kt will be
possible mainly for klga kjfk kisp kbdr kgon and mainly during
the morning hours. Winds veer more ene late aftn early eve.

Outlook for 06z Tuesday through Friday
Monday night MVFR towards daybreak.

Tuesday MVFR ifr. Sct -shra daytime then rain at night.

Wednesday-Thursday Vfr. Chc W gusts 20-25kt on weds.

Friday Chc MVFR and rain pm.

Marine
Low pressure will move offshore today. The pressure gradient on the
backside of the low will bring gusts up to 25 kt on the ocean waters
with the best chance through early afternoon. Ocean seas will
remain elevated between 5 and 7 feet through tonight. The small
craft advisory has been extended through 10z Tuesday. A cold
front approaches on Tuesday and then moves across the Tuesday
night. Ocean seas should remain elevated, but winds on the
waters will likely be 20 kt or less.

Elevated ocean seas are likely to persist into Wednesday and
possibly even into Wednesday evening before subsiding as high
pressure builds over the waters. There may also be some wind
gusts over 25 kt on the ocean on Wednesday in the wake of a cold
front. Sub-sca conditions are then expected through Friday.

Another chance of SCA conditions will be on Friday night, behind
another cold frontal passage.

Hydrology
No hydrologic impacts are expected through Tuesday afternoon.

There are currently no hydrologic impacts anticipated with
rainfall of 1 3 to 3 4 inches Tuesday evening and Tuesday night.

Locally higher amounts are possible.

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.
