previous discussion
Tonight, front becomes stationary to our northwest, and rain
showers move off from northwest to southeast. Overnight lows in
the 60s. Potential for some fog development along the coast and
northwestern Maine.

Tomorrow, low pressure system moves in behind this previous low,
bringing another surface low with an associated cold front
through the region. Aloft however, looking at some zonal flow
which helps to bring in some warm air. Looking at some dry
conditions, alongside warming temperatures. Highs tomorrow in
the mid-to-upper 80s in inland areas, and low-80s along the
coast. Relatively clear skies. Patchy fog possible tomorrow
night as well along the coast and waters. Lows in the 60s
throughout the area.

.SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/...
Tuesday night through Wednesday, weak return flow will bring
warm air advection over Maine and temps/dewpoints will continue
to rise ahead of an eventual cold front. Right now, the warmest
day looks to be Wednesday, when temps Downeast might rise to
near 90 degrees. At this point, it looks like we will be out of
the woods for any heat headlines, but that could change as we
get closer in time. Also uncertain at this point is whether
Thursday`s highs will be close to Wednesday, depending on the
timing of the cold front. If the front continues to slow down,
the upper level clouds will move in later and high temps will
have a chance to rise more quickly in the morning. The air
column will continue to be fairly moist, with dewpoints in the
mid 60s, so muggy conditions are in order even if we do not
quite make heat headline criteria. Instability will also
increase on Thursday ahead of the front, with showers and
thunderstorms developing in the warm sector.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
The cold front will move through the area at the end of the
week, with current timing showing anywhere from Thursday night
to Friday morning. Thunderstorms are likely along the frontal
boundary, with the possibility of early thunderstorms on Friday
further in the north. By mid- afternoon Friday, thunderstorms
and the front will be across the middle of the state, and cooler
air will follow behind. Highs on Friday will be in the mid-70s
across the north and closer to 80 across Downeast, where heating
will peak before the front moves through. High pressure will
dominate Saturday, and potentially Sunday as well. However, by
Sunday, models become increasingly inconsistent on the approach
of the next low pressure system. There is some indication a
front may move through Sunday afternoon, increasing the chances
for rain, but with timing differences in the models, confidence
is low.
