Synopsis
A cold front approaches the region tonight, and moves across the
area Monday morning. High pressure then slowly builds from the
north and west before settling over the region on Wednesday. The
high pressure then shifts offshore late in the week ahead of a
slowly approaching frontal system.

Near term until 6 am Monday morning
Only minor updates needed mainly to reflect current temperature
and dew point trends.

A weakening shortwave approaches and moves across the area
tonight. This shortwave will push a cold front across the area
late tonight early Monday morning.

Clouds will lower and thicken late this evening and overnight.

Dry air remains below 5-6 kft, and upstream observations suggest
any mid level precipitation is struggling to reach the ground. In
addition, most model solutions continue to remain mostly dry as
the front trough get sheared out, but cannot rule out a passing
light shower or sprinkle as the front moves through. If precip
occurs, some of 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.

Short term 6 am Monday morning through Monday night
The front should pass south of the area early Monday morning.

Once the front passes through, canadian high pressure builds
across the great lakes region. Temperatures climb to around 50
Monday afternoon as skies clear out across much of the region.

The far southern portion of the CWA may see clouds hang around
for much of the day as low pressure passes well south of the
region. Temperatures fall into the 20s Monday night under clear
skies.

Long term Tuesday through Sunday
Below normal temperatures will settle across the region on Tuesday
as polar high pressure builds from the north and west. Apart from a
few wisps of cirrus, skies will generally be clear, with winds
gradually decreasing through the day, setting the stage for
favorable radiational cooling conditions overnight. Expect highs in
the upper 30s to mid 40s, and lows in the 20s with the exception of
the nyc metro and immediate suburbs, where lower 30s will be more
common.

By Wednesday, increased subsidence as deep layer ridging builds
directly over the region will allow for a continuation of clear
skies, but warmer temperatures closer to climatological normals. The
surface high shifts offshore late in the day, allowing onshore flow
and warm advection to return. Despite calm winds and clear skies,
lows should be a few degrees warmer than the previous nights.

The warming trend then continues into late week with strong warm
advection in southwest flow between the departing high and a slowly
approaching cold front. Although the flow off the cold ocean will
keep coastal areas in the 50s, the interior will likely see high
temperatures in the 60s, possibly even near 70 by late week.

Similarly, low temperatures will be progressively warmer each day.

There remains significant uncertainty with the timing of the cold
front for late week, which will likely struggle to advance eastward
given the strong deep layer ridging to the east. For now, will keep
low end chances of precipitation. Additionally, several days of
onshore flow may allow for the development of marine stratus,
leading to daytime highs a few degrees colder and lows a few degrees
higher than currently forecast for coastal areas. Will continue to
monitor.

Aviation 02z Monday through Friday
A cold front approaching from the NW will pass through the area
late tonight, followed by building high pressure.

Vfr through the TAF period. SW winds less than 10 kt overnight,
becoming light and vrb in spots. Timing of winds shifting to
the w, then NW could be off by an hour or so. Directions
expected to remain right of 310 degrees magnetic aft 11-12z.

Outlook for 18z Monday through Friday
Monday through Friday Vfr. S-sw gusts 20 kt possible thurs.

Marine
A few occasional gusts to 25 kt, especially on the far eastern
ocean waters may be possible this evening. Otherwise, expect
winds to continue to subside. A cold front then approaches
tonight and passes to the south on Monday. Northerly winds
increase behind the front late Monday and Monday night. Winds
may reach SCA conditions Monday night into early Tuesday
morning, however it looks short lived and marginal, so will not
hoist any new headlines at this time.

Conditions then quickly become tranquil, as high pressure settles
over the waters into Wednesday. The high then shifts eastward
into the late week, allowing a return to a breezy s-sw flow and
a developing s-sw swell that will allow seas to continue to
build into the weekend.

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

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

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 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.
