Synopsis
High pressure will maintain dry weather today. An approaching
front will return shower and thunderstorm chances to the area
late this week.

Near term until 6 pm this evening
Dry weather and mostly sunny skies today as high pressure
slides across the region. High temperatures are expected to be
around 5 degrees below the seasonal average.

Short term 6 pm this evening through Friday night
Some increase in cloud cover is expected tonight in warm
advection ahead of an approaching shortwave as the high exits
the mid atlantic coast. This wave is progged to track across srn
ontario and NW pa thu, with shower and thunderstorm chances
increasing mainly near and N of I 80. Shear is progged to
increase, though unfavorable lapse rates and instability should
limit any significant severe weather potential.

Another, weaker shortwave is progged to take a similar track
early Friday, maintaining precip chances. Shortwave ridging
behind the second wave should result in limited shower and
thunderstorm coverage during the afternoon despite building
instability. Warm mid levels should also help limit convection.

Maintained low chc pops Friday night with another weak shortwave
ahead of an approaching midwestern upper trough. A return to
above average temperatures is expected by Thursday.

Long term Saturday through Wednesday
The midwestern upper trough is progged to advance E Saturday
driving a cold front across the area. Dry weather is expected to
return Sun Mon as surface ridging builds underneath the upper
trough. Another trough is progged to advance E from the midwest
and plains regions tue, though with uncertainty in timing and
location limited pops to the chance category for now on the 4th
of july.

Vfr through the forecast period. Surface flow will remain out

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.
