Synopsis
Looks like an exceedingly quiet period of weather over the next
few days in northern new england. Expect temperatures to drop a
bit behind a cold front that moved through today. High pressure
over the central united states will start to migrate east,
keeping sunny skies in place through at least Thursday. High
pressure will finally move offshore over the weekend, allowing
for a chance of precipitation as we exit the month.

Near term through tonight
A weak cold front moved through the area today, bringing some
gusty winds and cooler temperatures to the region. The
relatively cold air that has filtered in behind the front will
especially make itself known tonight. Drier air and good
radiational cooling will allow temperatures tonight to drop into
the single digits above zero over the mountains, with overnight
lows near 20 at the coast.

Short term Tuesday through Tuesday night
High pressure will continue to push into the region from the
west. This will result in sunny skies and seasonable
temperatures. With dry air in place near the surface, do not
even expect to see anything in the way of fog Tuesday night.

Long term Wednesday through Monday
Global models are in fairly good agreement for the long-term
portion of the forecast through Friday as a large surface high
will be centered of new england at the start of the long term
forecast period. The high will drift off the east coast by
Thursday morning allowing for moderating temperatures in the
southerly return flow. A weak cold front tries to cross the
region early Friday. The GFS has more moisture with this feature
than the ecmwf. A few showers may accompany this
front... Especially over northern mountain areas. The front will
stall and then push back north as a warm front Friday night as
low pressure over the midwest moves northeast. This front again
may result in showers over northern and mountain areas. Behind
the front a push of relatively mild air for Saturday into
Sunday. As the low moves through quebec late on Sunday a
trailing cold front will result in showers Sunday afternoon and
night... Followed by a cool down for Monday. It should be noted
that the GFS is 12 to 18 hours faster with the passage of the
cold front. If it is correct then the showers would arrive
Saturday night into Sunday. For now have leaned toward the ecmwf
timing.

Aviation 18z Monday through Saturday
Short term...VFR conditions should dominate throughout the
entire short term.

Long term...VFR conditions Wed and thu. Areas of ifr possible
Thursday night and again Friday night over central and northern
areas as a couple of fronts cross the area.

Marine
Short term... Expect to see some gusts this evening to around
20kts over the waters, but conditions should stay below sca
criteria.

Long term... Winds waves below SCA levels Wednesday. Increasing
sw winds will result in a prolonged period of SCA waves late
Wednesday night... Continuing into Friday. Another round of sca
waves will likely occur on Saturday. SCA level winds will
develop on Thursday and last into Friday. Have shaved wind
speeds a little due to warm advection winds over the cold
waters potentially restricting how much of the winds above the
boundary layer mix down to the surface.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... None.

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.
