Synopsis
Weak high pressure will bring dry weather this morning. 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
7 am update...

cirrus and some low clouds which developed over central eastern
ma and ri this morning have kept temperatures warmer than
expected. Temperatures hover in the 40s for much of southern new
england; 50s along the coast. Regional radar continues to show
light returns, but much if not all of this is falling as virga
given the very dry mid levels which will take some time to
saturate. The most likely location to see appreciable precip
first will be southeast ma by early afternoon where moist low
level flow undercuts the drier mid levels. Expecting at least a
little bit of sunshine to start the day, but it shouldn't last
long as clouds continue to thicken and lower.

Previous discussion...

22 00z guidance continued to advertise the idea of a very dry
layer between 5-10 kft. This dry air will need to be overcome
before rainfall can begin in earnest. This should take most of
the day. Right now, am focused on two areas most likely to see
rainfall during the afternoon. The first area will be towards
southeast ma where onshore flow should result in lower clouds
and some patchy drizzle. The other area will be along and west
of the ct river, which may be in range of an approaching mid
level shortwave and surface cold front.

Clouds will limit sunshine into this afternoon. Below normal
temperatures are expected.

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.
