showers possible late Sunday into Monday.

Near term through Friday
As of 139 pm edt Thursday... Wind advisory in effect till
midnight for localized gusts to 50 mph along the central and
southern western slopes of the green mountains.

Rain showers will continue through about 06z then become more
stratiform as a larger slug of moisture moves over our forecast
area from 06z till about 10z. Deeper moisture and stronger lift
aid in spreading the widespread rain across the area. Low
pressure system will move along ny NE coast overnight. Heaviest
qpf will fall during this time, generally around a quarter to a
half an inch of rain overnight. Temperatures will remain mild
overnight with min temps only in the 50s with plenty of clouds
and precip. By Friday morning the low pressure system will be
over CAPE cod and continue to move northeastward into the gulf
of maine by 00z. Rain showers will continue through the day
Friday, though lighter than the overnight. Heaviest
precipitation for our forecast area will be over eastern
vermont, closest to the actual low center. Chances for
precipitation will diminish from west to east during the
afternoon hours. Maximum temperatures will be cool, generally in
the 50s across the area.

Short term Friday night through Saturday night
As of 350 pm edt Thursday...

vertically stacked low pressure system near nova scotia Friday
evening moves east and out to sea overnight Friday night. Some
lingering light rain showers or drizzle early will gradually dry
up from west to east with some gradual clearing by Sat morning.

Lows mainly in the 50s.

Saturday will see weak surface high pressure build in to start
the memorial day weekend. Partly cloudy skies and 850 temps of
8-10c will yield warmer temperatures with highs 70s. Lows in the
mid 40s to mid 50s.

Long term Sunday through Thursday
As of 350 pm edt Thursday...

the long term starts out on Sunday with an upper level ridge over
the east coast with a developing light southwest flow at the surface
as weak high pressure moves out to sea east of new england. 850mb
temps are around 10-11c which should yield high temps in the 70s
perhaps upper 70s in the valleys.

As the ridge shifts east, cloud cover increases in the afternoon and
evening as an upper level low pressure system tracks west of the
great lakes with warm advection during the overnight hours into
early memorial day with a period of showers. A weak cold front
Monday evening trough will swing through with shortwave energy,
bringing with it showers with perhaps a thunderstorm or two
with some marginal instability.

Tuesday through Thursday there will be on and off mainly afternoon
and evening showers as a second cold front and several post
frontal trofs swing through the region. Cold advection will
bring 850mb temps down from 8-10c on Tue to around 6c Wed and 4c
on thu. The cold advection and daytime heating will contribute
to very weak instability and scattered showers. Corresponding
high temperatures will be start out in the 70s on Tue falling
back into the 60s Wed and thu. Lows will in the upper 40s to
lower 50s.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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 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.
