Synopsis
A warm front will pass through the area this morning, followed
by a cold frontal passage this evening. High pressure then
returns for Tuesday. A cold front will move across the region
on Wednesday, followed by high pressure through Friday. An area
of low pressure will pass north of the region on Saturday,
bringing another cold front across the area on Saturday. High
pressure briefly moves over the area on Sunday and Monday

Near term through tonight
A warm front approaching from the southwest will lift through
the region this morning. Overrunning showers ahead of the
boundary will move into the area from SW to ne, likely in the
metro area around 4am. These showers will continue and expand in
coverage until the front passes later this morning.

Probabilities for rain decrease for a couple of hours this aftn
with the region warm sectored and then will increase again late
in the day and this evening as a cold front moves through. There
could be a few rumbles of thunder as well with the cold frontal
passage. Some of the wind from the 35-45 kt LLJ could mix down
in any heavier showers tstms this eve. Highest rainfall should
be across long island where interaction with the strongest part
of the LLJ will occur.

Temperatures will rise early this morning due to increasing
cloud cover and warm advection. Highs should generally range in
the mid to upper 60s.

Winds will increase to 10 to 20 mph with gusts 25 to 35 mph this
aftn and eve, highest at the coast behind the cold front. This
strong CAA will result in lows generally in the mid to upper 40s
tonight with clearing skies after midnight.

Short term Tuesday
Rain should be clear of the area by Tuesday morning, with winds
gradually diminishing through the day as high pressure builds
in from the west. Mostly sunny with high temperatures around 5
degrees below normal.

Long term Tuesday night through Sunday
The long term period starts off with an upper level trough moving
across the northeastern portion of the us. At the surface, low
pressure moving from west to east across canada will drag a cold
front across the area on Wednesday. There is not much moisture
associated with this front, with the best chance for any
precipitation should remain north of the forecast area. Will
continue to keep the front moving across the area dry. Behind the
front, there will be strong cold air advection as winds increase and
become more nw.

High pressure builds into the region Thursday and moves offshore
Friday. This will allow another upper level trough and surface cold
front to approach and move across the region Friday night through
Saturday night. Unlike the cold front that moves across the area
earlier in the week, this front is expected to bring rain showers to
the region as it moves through. Drier and cooler conditions are
expected to end the weekend.

Temperatures on Wednesday will range from the middle 50s to lower
60s, then fall into the upper 40s and lower 50s on Thursday behind
the cold front. Temperatures then rebound a bit on Friday and
Saturday as highs reach the upper 50s and lower 60s. Temperatures
fall back into the 50s for the end of the weekend and early next
week.

Aviation 07z Monday through Friday
A warm front approaching from southeastern pennsylvania will
move through the terminals this morning into early this
afternoon. A cold front then follows this evening.

Vfr, becoming MVFR as light showers move into the terminals 07z
to 12z, southwest to northeast. Showers end, with MVFR
ceilings, however, conditions may briefly improve toVFR ahead
of the cold front. Showers and possibly isolated thunderstorms
will develop late this afternoon and continue into the evening
with MVFR conditions.VFR develops toward the end of the
forecast period.

S-sw winds under 10 kt increase to 10-15kt. SW gusts 20-25kt
develop late this afternoon.

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.
