High pressure builds to the north before drifting east during
the first half of the work week. A cold front approaches
Wednesday and passes through the region Thursday. Another cold
front passes through late Friday into Saturday. High pressure
returns late Saturday.

Near term until 6 pm this evening
Clouds have been slow to develop and advect into the area so far
this morning. Still thinking that skies will become mostly
cloudy for a period across coastal areas this afternoon, but may
have several hours of partly to mostly sunny skies first this

In addition to the clouds, persistent east to northeast flow
will result in a chance of light rain or drizzle today,
primarily across coastal areas. Precipitation amounts are
expected to remain light, with only a few hundredths of an inch
of rain at most. Across the interior, conditions are expected to
remain dry despite an increase in clouds. Afternoon highs will
remain several degrees below normal, in the mid 70s.

There is a high risk of rip current development at atlantic ocean
beaches today.

Short term 6 pm this evening through 6 pm Monday
While any lingering light rain drizzle comes to an end tonight,
low level moisture will linger into at least Monday morning as
easterly flow continues with high pressure remaining north of
the region. This will lead to continued mostly cloudy conditions
along the coast before more sunshine returns by Monday
afternoon. Temperatures on Monday will remain below normal,
with highs once again only topping out in the mid 70s.

There is a high risk of rip current development at atlantic ocean
beaches on Monday.

Long term Monday night through Saturday
Ridging along the east coast of the united states to start the
period will drift into the western atlantic by Tuesday as a longwave
trough from near alaska digs into the northern plains and upper
midwest. This longwave trough will send a couple of cold fronts
through the region Thursday and Friday. The strongest front will be
late Wednesday night into Thursday. The upper trough weakens
Thursday with the flow becoming more zonal during Friday when
another, and weaker, cold front crosses the region.

The area will remain dry on Tuesday as high pressure remains in
control, with only an increase in high clouds ahead of the cold
front traversing the great lakes.

With the front Wednesday into Thursday both CAPE and
instability will be limited, so will have showers with only
isolated thunder possible. There are some timing differences in
the timing of the frontal passage, but sided with the faster
guidance. Another weak cold front passes through Friday into
early Saturday with just a slight chance of showers as there
will be little moisture or forcing with the front. With the
upper trough weakening have slowed the timing of this second

After temperatures a few degrees below normal on Tuesday, near
normal temperatures are expected through the remainder of the long
term period, with highs generally in the low to mid 80s and
overnight lows falling into the 60s.

Aviation 12z Sunday through Thursday
High pressure builds over new england through Monday.

Ne winds 10-15 kt today. Gusts up to 20 kt are likely for all
terminals except kswf. Gusts end this evening with NE winds
around 10 kt overnight into Monday morning.

MainlyVFR through this evening. There could be brief MVFR
ceilings, mainly across eastern long island and southeast
connecticut this morning or early afternoon. There is also a
chance of some sprinkles or pockets of light rain near the coast.

MVFR ceilings likely develop early Monday morning.

Outlook for 12z Monday through Thursday
Mon MVFR possible early, thenVFR.

Tue Vfr.

Wed MVFR or lower possible in showers and isolated

Thu MainlyVFR. Morning showers possible.

A small craft advisory is in effect for the ocean waters through
Monday as strong northeasterly flow will result in winds gusting to
25 to 30 kt and seas building to 4 to 6 feet. While winds will
gradually diminish during the day on Monday, seas will likely remain
elevated into Monday night.

The flow the weakens into midweek as high pressure retreats off the
new england coast and a cold front approaches. With the approach of
the front winds also gradually shift to the southeast and south. Sub
sca conditions are expected by Tuesday and continuing into

No hydrologic impacts are anticipated through the end of the

Tides coastal flooding
A prolonged period of easterly flow will gradually increase tide
levels into mid week. Localized minor coastal flooding is possible
with Monday evening high tides along the south shore back bays of
queens and nassau counties, with the threat of at least isolated
minor coastal flooding continuing during the evening high tide
cycles through the mid week period.

Nyc NOAA weather radio station kwo35 (162.55 mhz) remains off
the air.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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 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.
