Synopsis
A warm front will cross through portions of new hampshire today.

This will transport increasingly warm and humid air into the
area with summerlike temperatures and humidity likely south of
the mountains on Monday. A cold front moving into the region
late Monday will bring showers and thunderstorms to the area
before much cooler and drier air works back into new hampshire
and western maine for midweek. A weather disturbance will cross
the region Thursday night, followed by fair weather on Friday.

Another warm front will approach the region on Saturday.

Near term until 6 pm this evening
High pressure is drifting offshore to the southeast early this
morning as a warm front approaches from the southwest. Some
light shower activity showing up north of this boundary across
eastern ontario and southern quebec and expect this activity to
begin spilling into northwest zones around daybreak.

Farther back to the southwest convection is firing across
western new york and some of this activity may make it into the
connecticut valley and southern new hampshire later this
afternoon. Elsewhere mostly cloudy skies and scattered showers
will prevail for most of the day with the best chance of precip
in northern zones. Will be a sharp difference in temperatures
across the region with central and northern maine and far
northern new hampshire only reaching the 50s. Southern new
hampshire and adjacent southwest maine will range from the mid
60s to the mid 70s.

Short term 6 pm this evening through 6 pm Monday
Warm front will lift north of the region overnight. Showers will
be likely through the night with the best chance of precip in
northern and eastern zones. Lows will range from the mid 40s to
lower 50s in northeastern zones and mid 50s to mid 60s in the
southwest.

Cold font will approch the region from the west on Monday and
this will set the stage for possible severe weather in the
aftenoon. Hard to say exactly how much Sun will be seen across
the region Monday morning but southwesterly boundary layer winds
should help push low level clouds eastward so should just be
dealing with variable clouds through early afternoon. Heating
should be sufficient to push temperatures into the mid 70s to
lower 80s over a good portion of new hampshire and western
maine. Respectable capes along with strong uni-directional
shear will raise the potential for bowing line segments and wind
damage with these storms. SPC has the entire forecast area in a
margianl risk for severe thunderstorms.

Long term Monday night through Saturday
00z model guidance in relatively good agreement this morning
with the timing and location of a cold front Monday evening.

This strong boundary should move off the coast around 00z,
pushing showers and thunderstorms offshore during the evening.

Instability is sufficient early for thunderstorms to contain
strong gusty winds and the unidirectional flow remains rather
strong from the west.

Strong cold air advection continues on Tuesday underneath a
strong upper level low pressure system. There will be quite a
temperature range with highs only in the 40s north to the 60s
along the coast. This relative warmth over southern sections
will be aided by significant downsloping. Steep low level lapse
rates will allow for CU to form, especially in the mountains
where showers can be expected.

There will be more Sun and less wind on Wednesday as the cold
pool aloft begins to shift east. A northerly flow should prevent
a sea breeze from forming during the afternoon with 60s expected
along the coast once again.

High pressure will crest over the region Wednesday night
allowing for radiational cooling and chilly temperatures in the
30s in the north and mountains.

Cyclonic flow aloft sharpens late Thursday and thurday night
enough to quickly bring a short wave across the region from the
northwest. Showers can be expected as a weak area of low
pressure crosses southern new england embedded in a fast
northwesterly flow aloft.

A warm front will then move into western sections early next
weekend. This will increase our chances for showers and
thunderstorms once again.

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