Synopsis
Strong high pressure will build in through today, then pass east
tonight. A cold front and wave of low pressure approaches
Wednesday and passes Thursday. Thereafter, a series of weak
fronts pass across the area through the weekend and into next
week.

Near term until 6 pm this evening
Deep-layered ridging for the region today brings sunshine mixed with
afternoon clouds. Winds subside through the day as the surface ridge
axis approaches and moves in during the afternoon. Associated
subsidence will limit the mixing depth, but this will be a moderated
airmass, so it won't be as cold as it was yesterday. It'll still be
below normal, with highs mostly 25-30. Wind chills through mid-
morning will be from around 0 to 10 below.

Short term 6 pm this evening through 6 pm Wednesday
Weak warm advection and partly to mostly cloudy skies will help
prevent tonight's temperatures from falling as low as they have for
the past couple of nights. Low temperatures will still however end
up at least a couple degrees below normal.

For Wednesday, weak low pressure moves through the great lakes
region. Warm advection continues over here during the day with a s-
sw flow. Temperatures and chances of pcpn therefore rise through the
day. Models agree that pcpn chances are mainly in the afternoon, but
can't rule out something reaching the ground late in the morning
mainly west of the hudson river. Thermal profiles support rain from
aloft with a strong enough warm nose, although mixed with sleet
should anything fall in the morning. However at the surface,
temperatures for some areas north and west of nyc could still be
freezing until early afternoon. Temperatures rise into the mid-upper
30s by day's end for these areas, with lower 40s at and near the
coast.

Long term Wednesday night through Monday
Closed upper low remains in the vicinity of hudson bay as a longwave
trough extends across the middle of the country downstream from
pacific ridge.

In time, heights across the east fall as the trough makes some
progress east as the upper low traverses slowly south.

At the surface, a cold front approaches Wednesday night, with a wave
of low pressure developing on the front along the appalachians
Wednesday night, passing in our vicinity Thursday.

Thereafter, a series of frontal boundaries or troughs pass through
the weekend and into next week.

Temps warm Wednesday night into Thursday as southerly flow
increases. Increasing lift due to WAA and increasing moisture
through the column will lead to moderate to at times heavy rain
later at night and into Thursday ahead of the wave of low pressure.

Once this front passes, drier and colder air settles back in on nw
flow Thursday night into Friday.

In fact, after a mild, above normal day Thursday, colder and below
average air moves back in Friday-Saturday, before moderating again
later this weekend and into early next week.

In general, much of the weekend can be characterized as unsettled with
multiple weak disturbances moving through.

Aviation 09z Tuesday through Saturday
Canadian high pressure builds over the area today, then slides
offshore into tonight.

Vfr through the TAF period.

Nw winds diminish this morning. Gusts should abate throughout by
around 07-09z as speeds decrease to around 10-15kt. Speeds continue
to slowly decrease to less than 10 kt, at all terminals, as winds
gradually back to the wnw-w by early-mid afternoon. Winds become
light and variable areawide by late afternoon early evening and
remain so through at least 06z Wednesday.

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.
