High pressure will build into maine this morning and shift east
of the area later today. A warm front will cross the region
Friday. A cold front crosses the region Saturday and stalls
across the gulf of maine Sunday into Monday.

Near term through tonight
1159 am update: pleasant temperatures and humidity continue this
afternoon. Had previously increased today's hi temps towards
the coast slightly with offshore flow. Not too confident about
fog along the coast later tonight and will keep it offshore
until late fri, but there will be a sea breeze along the coast
Friday that will keep highs in the lower 70s vs low 80s inland.

The warm front on Friday doesn't present a strong case for
afternoon convection at this point. The better elevated
instability arrives in the evening, but without much moisture or
a good trigger. Humidity will be on the rise in conjunction
with the southerly flow on Friday as dew points rise from the
current readings in the 40s and 50s back into the mid to upper
60s by later Friday.

Previous discussion:
high pressure in quebec is centered just northwest of quebec
city early this morning. The high center will move over maine
later this morning before beginning to slide east of nova scotia
by this evening. Today will be sunny with comfortably low
humidity as dew points will be in the 40s across the crown of
maine and 50s down east. High temperatures will mostly be in the
upper 70s to around 80 degrees, but cooler along the coast. As
the high continues to shift east weak onshore flow develops
tonight with the dew points beginning to slowly creep up. Patchy
fog may develop along and near the coast after midnight along
with the possibility of some lower stratus, especially along
coastal hancock county. Lows will still be relatively
comfortable and mostly in the 50s.&&

Short term Friday through Saturday
Warm front moves through early Friday paving way for a warmer
and muggier airmass. Highs Friday will mainly be in the low 80s
with dewpoints rising into the low 60s. Enough instability for
perhaps some afternoon storms with the best chance being in
western portions of the area.

Friday night, marine layer strengthens thanks to nice onshore
flow ahead of a weak approaching cold front. With the marine
layer, expect areas of fog especially for downeast, though
marine stratus and low clouds could stretch as far north as
northeast aroostook. Will be a very mild night with lows in the

Saturday is setting up to be a dangerously hot day with highs in
the mid to upper 80s north and low 90s much of downeast. The
problem will be the muggy airmass, with high confidence in
dewpoints around 70 downeast and mid 60s north. Good shot at
heat advisory criteria being reached south of millinocket
(criteria is 95 or greater heat index for >= 2 hours).

High uncertainty in thunderstorm chances for Saturday. Models
seem to be backing off some on storm chances. One inhibiting
factor is a potential mid-level warm layer capping convection.

Also, the surface cold front moving through is quite weak and
there is little in the way of an upper level shortwave... Just
zonal flow. If the cap can break, there could be some pretty
good storms, but odds seem to be favoring it not breaking.

Long term Saturday night through Wednesday
Weak cold front stalls near or just offshore Saturday night. Not
as hot and a touch less muggy on Sunday. Upper level trough
moves through on Sunday bringing a shot at showers and storms,
though confidence not high on this feature and went with chance

Heading into Monday through Wednesday, fairly dry NW flow sets
up over the area with near average temperatures and fairly low
humidity. Can't rule out some showers especially in the
afternoon hours, but overall looking dry.

Aviation 16z Thursday through Monday
Near term:VFR at the aroostook county terminals through tonight.

Vfr at kbgr, with low confidence of patchy fog toward daybreak
Friday with local MVFR.VFR at bhb through this evening, with
moderate confidence that there will be some lower clouds and
patchy fog after midnight with ifr conditions possible after

Short term:
Friday... Ifr MVFR coastal downeast early, otherwiseVFR outside
any afternoon scattered showers and storms. South wind 10 to 15

Friday night and Saturday... Ifr likely downeast and perhaps
north to aroostook county Friday night and early Saturday.

MostlyVFR Saturday afternoon. West wind 10 to 15 mph Saturday

Saturday night and Sunday... GenerallyVFR, except ifr possible
coastal downeast, and lower conditions possible in any showers
or storms. Fairly light winds.

Monday...VFR. Fairly light winds.

Near term: the wind and seas will remain below small craft advisory
levels through tonight. Patchy late night fog is possible

Short term: conditions remaining below small craft. However, fog
and low clouds will be an issue through Saturday night.

Near record high temperatures possible Saturday. The record
high temperature in bangor on Saturday, 7 20 is 96f set in 1991,
and we are forecasting 93f. In millinocket, the record high on
7 20 is 93f set in 1991, and we are forecasting 93f. The
records in caribou and houlton appear to be out of reach at this

Near record warm low temperatures are possible Saturday

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.
