Synopsis
A frontal system will approach today into tonight with a wave of low
pressure riding along it to our north Thursday morning. The low will
drag a cold front across the region Thursday afternoon. High pressure
will then build into the region Thursday night and remain
nearby through Saturday. A cold front will approach and move
across the area on Sunday. Another cold front and low pressure
system will move across the area early next week.

Near term until 6 pm this evening
As low pressure moves across the great lakes region, associated waa
rainfall could occur this afternoon. Surface temperatures at this
time across parts of the lower hudson valley and adjacent areas of
nj and ct could still be at or around freezing. Freezing rain could
occur even with temps into the mid 30s due to the extended period of
sub-freezing temperatures leading up to today. However, widespread
rainfall does not look to be likely for any given area until
tonight. Therefore, will not issue a winter weather advisory for the
time being. If spotty freezing rain occurs, a special weather
statement could be issued to address impacts. Temps expected to
increase through the day with mid upper 30s by day's end across the
nw zones, ranging into the lower 40s for coastal zones.

Short term 6 pm this evening through 6 pm Thursday
Light rain spreads across the area tonight, and at the same time,
temperatures continue to rise on a s-sw wind flow. There's still
some concern that parts of the far NW zones could have surface temps
supportive of freezing rain at the time when rain becomes likely, so
will need to keep close watch on this potential.

Rain becomes more moderate early Thursday morning, and could be
heavy at times by mid-morning with strong isentropic lift and an
impressive llj. Approaching shortwave energy should enhance forced
ascent and also create weak destabilization aloft, increasing the
chances of heavier downpours. After collaboration with the
surrounding office, have issued a flash flood watch for Thursday.

Smaller stream and urban poor drainage flooding would be the main
threat. Timing of the greatest flood threat looks like morning to
midday. A cold front passes through during the afternoon with rain
probably coming to an end not too long after the passage, however a
strong upper jet streak shifts in with enhanced lift, continuing at
least chances of additional pcpn. Could be cold enough for a mix of
rain and snow for far NW areas late-day.

It should also become breezy, especially near the coast. Strong
winds with the LLJ will be not too far above the surface, however
with such a strong inversion, thinking is that none of the area
would likely see advisory-level gusts.

Long term Thursday night through Tuesday
High pressure builds into the area behind a departing cold front
Thursday night and remain in place through Saturday. This will
result in dry and cold conditions. Highs on Friday will climb into
the lower and middle 30s, while highs will struggle to get out of the
20s on Saturday.

The high moves offshore Saturday night, allowing a an upper level
shortwave and associated surface cold front to move across the area
on Sunday. This could result in a few snow showers, will keep pops
at chance or slight chance for now. No accumulations at this time are
expected with any of the snow showers.

A stronger shortwave and associated frontal system will move across
the area early next week, bringing yet another chance of
precipitation to the region. There are differences with the exact
track and placement with this next system, so details remain
somewhat sketchy.

Temperatures on Sunday through Tuesday will climb 30s and lower
40s.

Aviation 09z Wednesday through Sunday
High pressure over the area will slide offshore this morning. A
frontal system will slowly approach from the west today into tonight.

Vfr conditions are expected through this morning. Increasing chance
of light rain and MVFR conditions this afternoon into evening for
city and western terminals. There is a low end chance for mix of
sleet and freezing rain near kswf this afternoon. Ifr or lower
conditions likely develop from west to east this evening in steadier
light rain.

S SW winds 10 kt for the morning push will increase to 10-15 kt and
gusts to near 20 kt late this morning and afternoon for south
coastal terminals. S winds 10 to 15 kt for coastal terminals
tonight, increasing to 15 to 20 kt towards Thu morning push. Llws
from SW winds of 50-55kt@2 kft developing for coastal terminals by
evening.

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.
