Area Forecast Discussion
National Weather Service Gray ME
646 AM EDT Tue Sep 18 2018

.SYNOPSIS...
Heavy rainfall will continue across southern New Hampshire and
extreme southwest Maine today due to the remnants of Florence
moving through the region. Over central and northern areas
mainly dry conditions expected. The system will be fast moving
and exit by this evening followed by clearing, cooler and drier
air for the mid to latter part of the week as high pressure
builds into the region. A more substantial cold front arrives
Friday bringing more dry weather and fall like temperatures to
the area.

&&

.NEAR TERM /TODAY/...
645AM UPDATE...
Have made some adjustments to forecast rainfall and rain chances
based on latest radar trends and observations. Lebanon, NH has
already reported an inch of rain, so this activity is dropping
moderate to heavy rain. It is moving fairly quickly, though, and
should be offshore by early afternoon.

ORIGINAL DISCUSSION...
Axis of rainfall has begun orienting itself such that southern
and central portions of New hampshire will likely see the most
persistent rainfall, extending eastward into southern Maine.
This is occurring along and north of a developing frontal
boundary extending eastward from the remnants of tropical system
Florence. With a very humid air mass in place, and tropical
moisture being advected into the frontal boundary, expect a
solid 1 to 3 inches of rainfall within this axis before it moves
offshore this evening. Although flash flooding is possible
especially if some deeper convection can develop, the threat
remains too low for a watch. Temperatures today will be cooler
due to cloud cover and rainfall, but will still make the mid 70s
in most places. Meanwhile, a cold front drops in from the north
later in the day shifting winds to the north and bringing drier
air in.

&&

.SHORT TERM /TONIGHT AND WEDNESDAY/...
After the cold front moves through, expect cool and dry air to
move in from the north. Some showers may linger into Tuesday
night or even Wednesday morning. Temperatures will be 10 to 15
degrees colder for highs on Wednesday in the cooler air mass.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
A high amplitude ridge of high pressure builds across the
eastern U.S. Wed night and Thu with cool and dry conditions. By
Thu night into Fri a return south to southwest flow will
increase after the passage of a warm front and then briefly
bring a return to warmer temps and higher humidity. By Fri night
a strong Canadian cold front associated with a Canadian clipper
will move through the area, a few showers will accompany the
front. Behind the front a large Canadian ridge of high pressure
builds east from the Great Lakes across the northeast with much
cooler and drier air making it feel more like fall. The cool dry
conditions will last into early next week.

&&

.AVIATION /07Z TUESDAY THROUGH SATURDAY/...
Short Term... IFR conditions are likely in the heavier rain
moving through southern New Hampshire and southern Maine today,
but conditions may remain VFR north of this. Should return to
VFR tonight or at latest Wednesday morning.

Long Term...Mainly VFR except MVFR in scattered showers Thu
night through Fri night.

&&

.MARINE...
Short Term...Low pressure tracks across southern New England and
exits through the Gulf of Maine today. Winds may occasionally
gust to 20 or 25 KT but not widespread enough for a Small Craft
Advisory. A cold front drops down from the north tonight with
northeast winds behind it tonight into Wednesday again gusting
to near 25 KT.

Long Term...Winds and seas will remain below SCA levels Thu into
early Fri. By Fri afternoon an increasing south to southwest
flow in advance of an approaching cold front will likely
require a SCA. The cold front moves across the waters Fri night
with SCA conditions possible for a time over the outer waters behind
the cold front as winds become north and then northeast.
