Intermittent showers will persist during the overnight hours. A
developing coastal low near long island will bring an additional
period of steady rainfall during Friday morning. Friday will be
cloudy and cool overall with high temperatures remaining in the
50s. The upcoming weekend will feature a dry Saturday with some
scattered showers possible Sunday night into Monday.

Near term until 6 pm Friday evening
As of 1011 pm edt Thursday... Southeasterly wind gusts continue
to decrease along the western slopes of the green mountains late
this evening. Still a couple of isold gusts 35-39mph at wells
and mendon, vt... But overall trend is downward and we've chosen
to cancel the wind advisory a couple of hours early (at 02z).

Please see our public information statement from earlier this
evening for peak wind gust information along the western slopes.

Center of slow-moving closed 500mb low is located across WRN pa
and far swrn ny at 02z. Mid-level dry slot on ERN periphery of
the low center had shifted nwd into our region, but is no
disappearing from WV imagery as new cyclogenesis takes hold
south of long island. Seeing some fast moving showers moving
nnwwd across central vt and the ERN slopes of the adirondacks.

However, there will be another round of more significant rain
toward daybreak (09-10z) as activity south of long island wraps
nnwwd in newly forming cold conveyor belt around coastal low.

This will set up a rather raw cloudy rainy Friday with high
temperatures generally in the 50s. Afternoon high temperatures
will be about 15 deg below normal for late may. Light NE winds
will back into the north toward dawn with winds generally n-ne
10-15 mph during the daylight hours on Friday.

Short term 6 pm Friday evening 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.

Aviation 02z Friday through Tuesday
Through 00z Saturday... Mainly MVFR ifr conditions expected over
the next 24 hours as coastal low moves through the region. Some
easterly llws to 40 kts possible through 06z but should be
confined to areas generally east of primary forecast terminals.

Cigs a mix ofVFR MVFR at 00z, trending bodily MVFR by 06z and
ifr lifr after 12z Friday. CIGS may lift slightly at valley
terminals such as kpbg and kbtv after 18z Friday but confidence
only moderate of this actually occurring. Easterly flow,
occasionally gusty to 25 kt early will back to northeast
overnight while slowly abating, then prevailing
north northeasterly at 06-12 kts with moderate gusts after 12z
Friday. Scattered to numerous showers will continue overnight
before becoming more widespread after 12z Friday as deeper
moisture pivots around departing coastal system.

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.
