Synopsis
Spotty light drizzle rain develops this afternoon, with more
widespread rain tonight ahead of an approaching cold front.

Behind this front, dry conditions and seasonable temperatures
follow Wednesday afternoon into Friday. Another cold front may
bring a some showers late Friday into early Saturday. High
pressure builds in for most of next weekend before another
chance of rain next week.

Near term until 6 pm this evening
10 am update...

patchy low clouds are developing across sne which will become
more widespread into the afternoon as low levels become
saturated. Hi-res and global guidance indicating light qpf
developing, mostly after 18z. Still dry aloft and deeper
moisture doesn't arrive until tonight so expecting patchy
drizzle or light rain developing, first across SE ma then
expanding across rest of sne toward evening. Minor adjustments
to pops, otherwise forecast on track.

Short term 6 pm this evening through 6 pm Wednesday
Tonight... Approaching mid level trough and upper jet combined
with deepening moisture plume will result in an area of
rain showers moving west to east ahead of a cold front. Most of
the best dynamics still appear to be focused to our north. Have
increased pops due to high confidence in measurable
precipitation, however, expecting rainfall total to be under an
inch through Wednesday morning region-wide. Lowest rainfall
totals towards the south coast.

Wednesday... High pressure builds in behind a cold front. Winds
turn west. Decreasing clouds and becoming drier. Near normal
temperatures.

Long term Wednesday night through Monday
Highlights...

* dry and seasonable through Thursday
* light showers possible late Friday into Saturday
* dry latter half of the weekend before rain chances return next
week
Wednesday night through Thursday...

looking at the synoptic pattern for this period we see a broad
upper trough over the central eastern us centered around a
hudson bay low, while ridging over the eastern pacific moves
onshore along the west coast. By Wednesday night the latest lobe
of energy rotating around main low has moved out bringing
rising heights and building surface high pressure. This together
with a very dry post frontal airmass will bring clear skies and
dry weather well into Thursday. By Thursday afternoon wrap
around mid level moisture may introduce some scattered mid high
clouds but nothing significant. Most noticeable sensible weather
would be some breezy winds as model soundings indicate a well
mixed boundary layer tapping into the 25-30kt 850mb jet.

Friday and Saturday...

next chance of rain comes during this period, though still some
question to the timing and extent. Increasing moisture ahead of
an approaching shortwave trough will bring clouds on Friday,
preceding rain chances Friday evening and especially overnight.

Confidence remains on the low end given significant guidance
disagreement on the weekend pattern... GFS continuing to dig
deeper while the ec depicts a shallower, more transient wave.

For now going with a blend of guidance, favoring the quicker
solution; expecting to see showers move in around late Friday
and linger through early to mid day Saturday. Seasonable
temperatures Friday in the low 60s followed by a bit of a cool
down, in the 50s on Saturday. Behind the rain high pressure
builds in for cool, clear night Saturday. This may lead to some
frost Sunday morning with lows in the 30s.

Sunday and Monday...

increasing model spread, substantial by late weekend, leads to
decreased forecast confidence this late in the period. Seems to
be good consensus that Sunday stands a better chance of being
dry, while another frontal wave may bring rain back to the
forecast to start the week. For now introducing rain chances
during the overnight hours Sunday into early Monday.
