...FLOOD WATCH REMAINS IN EFFECT FROM LATE FRIDAY NIGHT THROUGH
SATURDAY EVENING...

The Flood Watch continues for

* Portions of northern Connecticut and Massachusetts, including 
  the following areas, in northern Connecticut, Hartford, 
  Tolland, and Windham. In Massachusetts, Franklin, Hampden, 
  Hampshire, and Worcester. 

* From late Friday night through Saturday evening

* Widespread rain with embedded heavier showers is expected to 
  develop late Friday night continuing through Saturday evening. 

* The longevity of the rainfall, possibly heavy at times, with 
  amounts forecast around 1 to 2 inches poses the threat for 
  urban and poor drainage flooding. 

* In addition, forecast rainfall will also exacerbate mainstem
  river flooding along the Connecticut River. It may also  
  contribute to a few smaller streams throughout the watch area to
  reach minor flooding. 

* Those with interests in low lying or flood prone areas should 
  continue to monitor the latest forecasts. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flood Watch means there is a potential for flooding based on
current forecasts.

You should monitor later forecasts and be alert for possible
Flood Warnings. Those living in areas prone to flooding should be
prepared to take action should flooding develop.

Area Forecast Discussion
National Weather Service Boston/Norton MA
403 PM EDT Thu Apr 18 2019

.SYNOPSIS...

A warm front lifts through Southern New England tonight and then
moves off to the north Friday. Warmer and more humid conditions
will stay with us Friday along with patchy light rain and drizzle
at times. A period of heavy rainfall is possible late Friday night
into Saturday night as slow moving low pressure approaches from
the west. The low pressure moves slowly across New England into
early next week. Off and on rain chances, perhaps a midweek dry
period before additional shower chances emerge late week into
the following weekend.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...

Warm front has advanced to Central New Jersey. With the upper
flow now turning from the southwest, expect the warm front to
trend north through Southern New England and off to the north.
This means a warmer more humid airmass moving into the region.
Expect low temps in the upper 40s and lower 50s early tonight
followed by slowly rising temperatures overnight.

Dry air at the surface and deep moisture above during the
evening, but this reverses as the warm airmass moves in. Expect
dry air above 850 mb and moist air below. Not much in the way of
showers, but with rising dew points in a moist surface airmass
we would expect sprinkles/drizzle during the night.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/...

Trough digging over the Eastern USA becomes a closed low Friday.
This further turns the upper flow out of the south, drawing
unseasonably humid air north. Precip Water values of 1.5 to 1.75
inches are forecast. This would be ho-hum for July, but not so
for mid-April. Average values for mid-April are 0.6 inches, and
high-end observed over the past 70 years have been around 1.4
inches.

Model time cross-sections concur, showing deep moisture
returning Friday afternoon and Friday night. Dynamics are less
helpful. Zone of favorable upper jet dynamics remains over NY/PA
during the period while low level jet and transport of moisture
doesn't ramp up until Friday night. With this in mind, we will
maintain low-end chance pops much of the day, ramping up during
mid to late afternoon. Likely-to-categorical pops for Friday
evening and night, with highest values over Western MA and
Hartford County CT.

The low level jet, as mentioned, maintains a broad 50-knot zone
just offshore during the day. A 60-knot maxima then moves up the
coast late afternoon and evening with axis aimed mainly toward
our western areas. This supports the idea of higher pops in
Western sections during Friday night, as well as the start of
heavier rain especially in Western MA/Northern CT.

Mixing to 950 mb would support max sfc temps Friday in the mid
60s. Airmass over the southeast USA shows observed dew points in
the 50s and lower 60s. We will expect this for our area
Friday/Friday night in the warm sector south flow. So Friday
night min temps would be upper 50s and low 60s.

Gusty southwest winds continue due to the low level jet.
Mixing is limited, but even from 950 mb we would see 25-30
knots.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...

*/ Highlights ...

 - Saturday into Sunday, river flood concerns along with potential
urban / poor drainage flooding ... also potential coastal flood
issues along S-coastal New England

 - Monday into Tuesday, scattered shower activity along with cooler
conditions prevails beneath the slow moving area of low pressure

 - Wednesday onward, cooler conditions with shower chance could
possibly prevail

*/ Overview ...

Soaking rains. Echoes of a S Greenland block (+NAO) buckling the up-
stream pattern as progressive N Pacific flow maintains a continuous
feed of energy across the CONUS. Amplified H5 troughs, especially E
of the Rockies, dipping S, tapping the sub-tropics, pulling poleward
anomalous precipitable waters and much warmer air, slowed over the E
CONUS. H5 trough-ridge pattern, N Atlantic energy downshears by the
weekend into early next week yielding a rex-block that continues a
slowed upstream pattern. Depending on the aforementioned N Pacific
stream, could see a setup of on-again, off-again, decent rains that
are potentially soaking through the end of April. Sweeping frontal
boundaries, likely to see some temperature swings dictated by the
direction of the wind. Spring continues to prevail. Details as to
significant forecast concerns / threats and impacts below.

*/ Details ...

Saturday into Sunday ...

1.) Interior flooding:

High confidence mainstem CT per headwater snowmelt and forecast rain-
fall. MMEFS concerns also signaling some smaller streams throughout
S New England potentially seeing actionable to minor flood issues.

But not highly confident on significant interior flooding elsewhere.
Likely ponding on roadways and possible urban / poor-drainage flood
issues, but widespread impact is seemingly less with the latest 12z
suite of forecast guidance. Low undergoing full maturation towards
occlusion, dry air wrapping in within the mid-levels, losing deep
column moisture while it appears deep layer ascent is seemingly weak
to diffuse.

Widespread rain with embedded heavier showers and potential isolated
thunderstorms does appear likely and it looks like generally around
1-2 inches rainfall with locally higher amounts somewhere in S New
England. But not absolutely sure exactly where. Hopefully we'll gain
greater confidence as convective allowing models become available as
to where and when heaviest rainfall will occur.

Focus Saturday, possibly lingering into Sunday, a slow moving system
up against a developing rex-block S of Greenland. Precipitable water
surge up around 1.5 inches beneath mid-level ascent and broader H3-5
diffluence aloft, but again, mid-level dry air could put the squash
on heavier rain outcomes. Lift/omega values up as high as around 20
micro-bars per second.

A feeling of a prolonged rain gradually adding up but not falling at
once, not exceeding flash flood guidance. FLOOD WATCH issued for the
W-half of S New England in collaboration with WPC and other WFOs. A
focus on Saturday to start coincident with EXCESSIVE RAINFALL out-
looks per WPC.

2.) Coastal flooding:

High astronomical tides plus longevity of S fetch, S-coast under the
greatest threat of inundation issues. MMEFS signaling tidal issues
at Westerly, RI. Particular focus within inner bays and sounds with
an eye on Narragansett and Buzzards Bay. Question whether if we push
over a foot of surge, then there's concern. Continual monitoring,
but right now it appears most spots will fall short.

3.) Winds:

H925 S winds broadly speaking 50-60 mph over all S New England with
possibly 70 mph along the immediate S coast. As to how effectively
these winds mix-down to the surface will need to be watched closely,
as to whether precipitation drag or isolated thunderstorms will
bring momentum downward and pose wind-related hazards to the region.

Much stronger inversion along the coast with cooler waters beneath
much warmer air aloft, however the threat exists more so across the
interior, especially the high terrain. Nevertheless, persistence of
15 to 25 mph S winds since Friday will ultimately aid in S surge of
water along the S-coast and the threat of coastal flooding noted
above.

Monday into Tuesday ...

Beneath the low, showers swirl. Winds subside thus the coastal flood
threat subsides. Additional water into the system but should remain
fairly light. Mainstem rivers remain in flood, perhaps some smaller
streams as well. Lean cooler conditions as the rex-block evolves to
the immediate E blocking the escape of the low E.

Wednesday onward ...

Perhaps drying out, warming up ... or additional upstream Pacific
energy continues the threat of scattered showers and cooler weather.
But then again 18.12z indications that the eroding rex-block keeps a
persistent H5 trof lingering over SE Canada, additional energy and
shower chances dropping S along with cooler conditions. Forecast
guidance has been adjusting, no true confidence.

.TIDES/COASTAL FLOODING...

With the strong southerly winds aligned with astronomical high
tides due to the full moon late this week, there is a small chance
for that a few locations along the south coast may see minor
coastal flooding around high tide tonight. Most information
suggests some splashover but short of actual flooding. Will
monitor for potential coastal flood headlines.
