.SYNOPSIS...
High surf and rip currents expected into Thursday as southerly
swells impact the coast. A cool and dry airmass arrives tonight.

this weekend, which then continues into early next week. Dry
weather is expected to prevail through early next week, with our
next chance for rainfall not anticipated until the middle of

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
230 PM Update:
Key Messages:
* Dry/quiet weather overnight
* Chilly with lows ranging from upper 30s to low 50s
High pressure builds over Canada builds southeast overnight. This
will support dry/quiet weather across souther New England. Northeast
winds associated with anti-cyclonic flow around the surface high
positioned to our north will advect cooler air over the region. 925
hPa temps drop below 5C and are likely to translate to surface temps
in the mid to upper 30s across the interior/high terrain and low to
upper 40s across eastern MA. Temperatures will be more mild along
the coast, especially on Cape Cod, in the upper 40s to low 50s. Some
patchy frost possible for location that experience temperatures
below 37 degrees.

.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
230PM Update
Key Messages:
* Still cooler than normal for Thurs (low to mid 60s highs), but
  full sun and easing northeast winds.
* Cool/dry again Thursday night with northeast winds becoming
  south/southwesterly
Thursday and Thursday night
High pressure settles over the region tomorrow supporting abundant
sunshine and dry weather. Temperatures will be below normal in the
low to mid 60s. Winds remain steady out of the northeast around 10-
15 mph for the first half of the day and gradually weaken as the
afternoon progresses in response to a weakening pressure gradient.
Dry/quiet weather persist into tomorrow night. Clear skies and light
winds should support efficient radiational cooling which will result
in another chilly evening with low temperatures generally in the
upper 30s/low 40s with locally lower/higher temperatures over the
high terrain and on The Cape/Islands respectively.
&&
.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
Key Messages:
* Protracted dry weather continues, with our next chance for rain
  not anticipated until the middle of next week.
* Above to well above normal temps for this weekend into early
  next week, potentially into the mid 80s this weekend.
Details:
Latest guidance did not show much change from previous
forecasts. Still expecting a high pressure to provide dry
weather into at least the early part of next week. Temperatures
still anticipated to be above normal this weekend into early
next week as well. The lack of rainfall will only exacerbate
fire weather concerns. Fortunately, not expecting winds to be
very strong during this portion of the forecast.
