Synopsis
High pressure will prevail through the first half of this week.

Meanwhile, hurricane maria is forecast to track north and pass
east of the carolinas on Wednesday before getting kicked out to
the east by an approaching cold front. The front will move
through Wednesday night into early Thursday. High pressure
builds in for Thursday and Friday. A weak low pressure area
moves through the region Saturday with high pressure returning
for Sunday. Refer to the latest national hurricane center
advisories for the official forecast on maria.

Near term until 6 am Monday morning
Forecast is generally on track, however backed off on the extent
of cloud cover overnight into Mon morning. Expecting similar sky
conditions as last night with perhaps some stratus making into
the east end of long island and portions of new london county
overnight. Hrrr seemed to have a good handle on current cloud
cover so it was used for the majority of the night. Narre
supports this.

Additionally, clear conditions and light to calm winds will be
favorable for fog development late tonight. Thinking extent
should be similar or slightly more widespread than last night
with the same airmass in place.

Short term 6 am Monday morning through Monday night
Another sunny warm day expected on mon, though not quite as
warm as today with onshore flow more prevalent. High temps will
range from the upper 70s lower 80s near the coast, to mid 80s
most elsewhere, to the upper 80s well inland, still above mos
guidance.

With another night of onshore flow, low stratus and fog should
be more prevalent as well, mainly inland NW of nyc, and also
across eastern ct long island. Low temps should be near or
slightly cooler than those expected tonight, in the upper 50s
and 60s.

Swells from distant hurricane maria will continue to produce
a high rip current risk and high surf.

Long term Tuesday through Sunday
A strong upper ridge and surface high will be remaining across
the region Tuesday as hurricane maria moves east of the
carolinas. The ridge slowly weakens Tuesday night into Wednesday
as a shortwave digs into the upper midwest and great lakes
region. The increasing westerly flow with the trough will steer
maria eastward from the carolinas, and into the atlantic,
Wednesday night through the end of the week. There will be
little moisture from the tropical cyclone and the cold front
moving into the region and will have mainly slight chance to low
chance probabilities. With a continuation of the easterly flow
Tuesday into Wednesday, low clouds and fog, with drizzle, will
be possible. Will include for Tuesday morning only at this time.

Refer to the latest advisories from the national hurricane
center for the official forecast on maria.

Anomalous warmth will remain across the region until the cold
frontal passage, when temperatures return to more seasonal
levels.

The forecast becomes more uncertain after Thursday as a re-
enforcing shortwave moves through the longwave trough and sends
another cold front into the region Saturday. At that time
temperatures may fall below seasonal normals.

Due to long period swells from maria, there is likely to be a
high rip current risk through the week.

Aviation 02z Monday through Friday
High pressure remains across the region through the TAF period.

Vfr through around 06z. Expect similar conditions as last
night... Although perhaps MVFR ifr fog is a bit more widespread
outside of nyc terminals. The stratus may also make it into kgon
overnight as opposed to last night.VFR returns 12z to 14z
Monday morning which will remain for all terminals during the
day Monday.

Light and vrb winds overnight through early Monday morning and
then increase to 5-10 kt out of the e-se into Monday afternoon.

Outlook for 00z Tuesday through Friday
Monday night-Tuesday MVFR or lower conditions possible with
areas of fog and or stratus and drizzle outside city terminals.

Tuesday night-Wednesday MVFR or lower conditions possible
with patchy fog and or stratus and a low chance of showers.

Wednesday night-Thursday MVFR or lower possible with
isolated to scattered shower activity.

Thursday night-Friday MainlyVFR.

Marine
Long period swells are producing 5-ft swells on the outer
portion of the coastal waters E of fire island inlet. Expect
5+ ft swells to reach all ocean waters overnight. SCA for
hazardous seas in effect thru tue, and those seas should be with
us into late week.

Long period swells will continue to produce hazardous seas on
the ocean waters at least through the forecast period, Friday.

On the non ocean waters winds and seas will remain below
advisory levels until Thursday. Gusty winds develop behind a
cold frontal passage Wednesday night into early Thursday.

Northwest small craft gusts will be possible late Thursday,
Thursday night and into Friday across all the forecast waters at
that time.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
