Synopsis
Even warmer temperatures arrive in the area today on a
southwesterly wind. A cold front moves through from the
northwest tonight, but temperatures behind it on Friday will
only be a few degrees cooler than today, still above normal. As
high pressure slides east this weekend a large ridge of high
pressure will build over the east coast while a deep trough
develops in the center of the country. This will keep warm,
humid conditions in new england into the first half of next week
with an increasing chance of rain toward the middle of the week.

Near term until 6 pm this evening
A weak front will approach from the west today. Ahead of this
moisture starved system, a southwest gradient will increase.

Mixing values will deepen as well this afternoon. Bufkit and
mesoscale models suggest that many areas will receive winds in
the 10 to 20 mph range with gusts as high as 30 mph. A strong
gradient will continue across the higher terrain as well.

Mainly sunny skies will yield afternoon and h8 temperatures
approaching at or above +10c will allow for highs in the lower
to mid 70s across most of our forecast area this afternoon. This
is a good 10 to 15 degrees above normal highs for this time of
the year. The record high temperature for the forest city is 81
degrees set back in 1963. We will fall short of that record.

Short term 6 pm this evening through 6 pm Friday
A few clouds may cross the region tonight with the passage of
the moisture starved front during the early evening hours. A
shower is possible across the far north as upslope winds kick in
initially from the west, then northwest.

Temperatures will settle down into the 40s in most areas tonight
despite some gradient winds and a few clouds. This is well below
maxi-min records for the region.

A sharpening upper level trough in the canadian maritimes will
allow for cold air advection to continue, mainly over eastern
areas on Friday. Very dry downslope conditions expected over
southern areas (see fire weather section for elevated conditions
both today and Friday below).

It will be slightly cooler on Friday. However, readings will
still be well above normal with highs well into the 60s in many
southern areas, with chillier 50s in the far north. Some CU may
hold in the mountains and foothills.

Long term Friday night through Wednesday
Surface high pressure slides east into the appalachians and the
mid atlantic states Friday night into Saturday morning. This
will bring good radiational cooling conditions overnight, but
especially to southwestern areas closer to the center of the
high. How low temperatures go will be dependent on low level
moisture which will be driest in the north. Expect lows in the
valleys to reach the low to mid 30s. Warm advection begins again
in earnest on Saturday with temperatures warming into the 60s in
the north and mid 70s in the south.

While surface high pressure shifts east into the atlantic, an
upper level ridge of high pressure will grow in amplitude over
the east coast in response to deep troughing over the center of
the country. This will keep a warm and increasingly humid flow
of air into new england, with temperatures generally in the 70s
during the day and dewpoints rising into the 50s, buoying
nighttime lows by the beginning of next week.

Eventually the upper trough over the center of the country will
make its way eastward, and it seems likely that a more organized
pressure system will develop and move north northeast along the
eastern side of the trough generally in the direction of new
england. This will provide a good chance of rain sometime in the
Tuesday Wednesday time period before the cooler air in the
trough arrives. Models still showing a wide range of solutions
on when and how this trough will move through, with the
potential existing for the trough to take the rest of the week
to make its way through. Thus rain chances will continue through
the week until a clearer picture can emerge from the mess.

Aviation 07z Thursday through Monday
Short term... MainlyVFR conditions this morning after isolated
inland valley fog. Winds will be rather gusty from the
southwest. MainlyVFR conditions continuing tonight into Friday.

Long term...VFR conditions expected through Saturday. Could see
morning fog in the valleys each morning beginning on Sunday.

Marine
Short term... Have raised scas for this afternoon and tonight for
all of the waters as a southwesterly gradient increases across
the region and seas build. The scas will continue into Friday
for the outer waters as winds shift to the west to northwest and
remain rather gusty. This update was to add casco bay to the
sca.

Long term... High pressure builds east across southern new
england on Saturday and into the atlantic on Sunday. A broad
southerly flow is expected to gradually increase in intensity
early next week as a frontal system approaches from the west.

Fire weather
A weak cold front will approach the region today.

Winds will increase from the southwest out ahead of this system
with most areas increasing to 15 to 20 mph with gusts as high
as 30 mph. At the same time, relative humidity values will fall
to 30 to 40 percent across new hampshire and adjacent areas
along the border in westernmost maine. The combination of the
gusty winds, low relative humidity values and our recent dry
conditions will allow for elevated fire weather conditions
today.

Elevated fire weather potential is expected today over western
portions of our forecast area. Will issue a special weather
statement to bring attention to this threat.

The front will cross the region tonight. Although the winds
will not be quite as gusty tomorrow, dry northwest winds will
allow for relative humidity values to be in the 30 to 35 percent
range across much of western maine and new hampshire.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
