An upper trough will cross the region tonight. Canadian high
pressure will then build across the region Tuesday through
Thursday then slowly settle south over the gulf of maine Friday
and Saturday.

Near term through Tuesday
One last S WV trof will cross msly the NE ptn of the fa late
this aftn and erly eve, with the potential of isold sct lgt
sprinkles shwrs peaking between 6 and 10 pm before movg ese into
nb late tngt. Llvl rh progs and the sc CU tool indicate fairly
solid sc cld deck lasting into the morn hrs Tue across most of
the fa before drier llvl air and increased subsidence associated
with the advcg can sfc hi reaches the rgn Mon aftn, resulting in
at least partial clrg. Given the cld cvr and N breeze,ovrngt
lows will remain well abv fzg even across the n, xcpt the the mt
katahdin summit where there could be flurries or a lgt sn shwr
by erly Mon morn. Hi temps Tue aftn will a be 1 to 3 deg cooler
than tdy despite some aftn sunshine.

Short term Tuesday night through Thursday
Highly amplified upper level ridge over the great lakes and central
ontario will increase mass transport from the north over maine
Tuesday night. Clearing skies will be one ingredient for
potential freeze in the north. Much of the cloud cover will
retreat to the south as center of high pressure approaches the
crown of maine during the evening hours. Mostly clear skies are
expected from the north towards interior downeast overnight.

Next important ingredient is light or calm winds, which will be
most prominent across the north woods and lower terrain after
midnight. Light northerly winds at 925mb continue during the
evening as CAA brings temps at this level down to 3-5c as the
inversion abv surface. The combination of clearing skies and
light winds with cold temps in place will really accelerate the
ventilation and radiational cooling of daytime surface temps
late overnight at ground level. Result will be chance for frost
from a greenville to houlton line north, with possible freeze
conditions across the north. Have issued a freeze watch in the
north as a result.

Dry conditions continue, as focus remains temperatures. Under
center of high pressure Wednesday, temperatures recover into the
lower 60s with plentiful sun. Wednesday night will be another
cold night, with mid to upper 30s plunging deeper south towards
the coast. Currently believe temperatures will be a tad warmer
as high tracks towards coast and gulf of maine. However, another
round of frost will be possible, perhaps further south just
north of the bangor region. Will need to watch surface winds as
they veer wsw after midnight.

Long term Thursday night through Sunday
Dry weather with mostly to partly sunny clear skies continues in
extended period. High pressure will dominate new england as
disturbances ride south and north of the large system. With
return flow setting up later in the week, highs will climb above
normal with some mid-70s likely for much of the forecast area,
with upper 70s near the bangor region. This will be quite the
change from early week lows temperatures. Along with warm temps,
will need to watch the seas as long period swells build into the
gulf of maine this weekend, possibly causing high surf. Much
uncertainty rises with location and strength of wave generation
due to hurricane humberto far off in the open atlantic.

Aviation 19z Monday through Saturday
Near term: tonight through Tue morn: NRN taf sites MVFR sc clgs.

Downeast sites msly lowVFR. Lgt N winds.

Tue aftn: all TAF sitesVFR or improving toVFR. Lgt N winds.

Short term:
Wednesday through Saturday...VFR expected across the region.

Some variable conditions are possible with valley fog in early
morning or late night hours. Winds will be light and from north
Wednesday, becoming predominantly west through Friday.

Near term: no hdlns anticipated ATTM thru this ptn of the fcst,
with fcst WV hts based on a blend of ww3 nwps WV guidance. Wvs
will be comprised of two main spectral groups durg this tm; a
3-6 sec offshore SE propagating short fetch group and a nnw
propagating 10-12 sec open atlc swell group.

Short term: winds and seas will remain below SCA levels through
Friday. Swells may build this weekend due to hurricane humberto
in open atlantic waters, but strength and duration of event
will determine whether high surf is generated in coastal waters.

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.
