What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
Showers are likely overnight S of the ma ct ri border as a low
pressure center sweeps W to E just S of new england. Bit cooler
with a spot showers Thursday. Seasonable Friday while turning
unsettled Saturday, continuing through early Monday with the
chance of showers and thunderstorms. Dry weather thereafter
through Thursday, with a renewed chance of wet- weather Friday
into the following weekend.

Near term until 6 am Thursday morning
7 pm update...

wet-weather likely along s-coastal new england following the
latest near-term high-res trends. Satellite exhibiting the likely
outcomes that'll play out overnight. N trof disturbance with
accompanying cold front pressing S out of canada as an area of
low pressure begins to emerge E from the mid-atlantic. Subsidence
between the two systems and drier air is evident across N new
england given clear slot observed via satellite. Coincident is
considerably lower thetae within the low levels per latest rap
guidance. Have updated pops and trends accordingly, keeping bulk
of activity S of a line from hartford- providence-plymouth. Can't
rule out a rumble of thunder along the immediate s-coast of new
england, but feel it more likely out over the waters, so the
islands with the better chance, following k indices and surface
lifted indexes, as well as showalters. Some patchy fog in addition
to wet weather, but mainly confined over waters and islands.

Rain moving in just around midnight, exiting the early morning
hours on Thursday. Latest radar returns just a pre-cursor, acting
to moisten the environment, however low-levels still considerably
dry as surface high pressure retreats off to the e.

Short term 6 am Thursday morning through Thursday night
Thursday into Thursday night...

precipitation along the south coast will be ongoing early in the
morning as surface low pressure continue to move across the southern
waters. Approaching wave from the northeast will drive this low
south and offshore leading to an end of the precip. Will have to
watch for a spot shower or two during the day across the interior.

Increasing low level moisture combined with steep lapse rates and
upper level trigger could lead to a few showers especially along the
higher terrain. Thus have insert a slight chc for a shower during
the afternoon.

Temperatures on Thursday will be warmer across the ct valley, but
quite cool along the east coast. Winds will switch from the
southwest to the northeast a front passes through. This will bring
the cooler maritime airmass onshore. Could see over a 10 degree
difference across the region.

Temperatures overnight will cool off, but not as much as prev
through. Increasing low level moisture trapped within the inversion
will result in stratus and fog across the area. Still trying to
narrow down best location, but something to watch for in the coming
shifts.

Long term Friday through Wednesday
* highlights...

- Saturday perhaps not a washout, skirting rains S e
- showers t'storms N W Sunday, sweeping SE into Monday morning
- prolonged dry conditions during the week
- watching weeks-end for additional wet-weather disturbances
* overview...

summer is coming. Prevailing N pacific h5 trof downstream of which a
split flow regime emerges over western N america. S tug by cascading
systems into a baffin bay gyre, h85 temperature warm anomalies build
into the great lakes st. Lawrence river valley per 5-day averages.

Subsequent higher heights, more dominant N atlantic high especially
towards bermuda, invoking a S warm, moist pump from the gulf. Would
appear seemingly that a general h5 trof pattern remains over the ne
conus, however weaker under an increasing weight of high pressure,
subsidence. Weak frontal boundary passages with uncertain outcomes,
where precipitation looks prominent upstream only to wash out upon
arrival. Confident warming trend into july, while a nod of concern
of drier than average precip, perhaps enhancing ongoing abnormally
dry conditions. Some unknowns, a NE atlantic rex-block evolving into
w europe, and tropical activity off africa into the caribbean. Will
hit on any targets of opportunity below.

* discussion...

Saturday...

lean away from heavy rain with wedging high pressure, drier air, as
the sub-tropical, +2" precipitable water airmass resides s, perhaps
skirting SE new england. Have seen this before with winter systems
in where isallobaric flow dams up against an approaching oh river
valley low. Can't rule out scattered shower, thunderstorm activity
towards days end, but leaning with 20.12z GFS nam in SE skirting
outcomes fueled by low-level convergent inflow towards a held-up
warm frontal boundary. De-amplifying mid-level trof, weak frontal
boundary parent, pushes the sub-tropical axis offshore ahead of an
oncoming sharper h5 trof axis for Sunday into Monday. Not ready to
call the day a washout.

Sunday into Monday...

afternoon showers and thunderstorms into evening, however mainly N w
interior locales. Possibly strong but not thinking severe per shear
and 0-6 km mean wind accompanying along with marginal instability.

Better sub-tropical, unstable and muggy airmass S e, offshore, yet
enough moisture that with destabilization should allow activity to
pop within cyclonic regime out ahead of overnight sharp cold front,
pushing offshore around Monday morning. Accompanying vortmax, strong
deep layer ascent, may have to watch SE new england into Monday up
against a more muggy airmass lingering offshore as to potential out-
comes. Thinking a majority of activity is nuisance.

Overall, for the 3-day period Saturday through Monday, could be a
situation of interior N W destabilization with s-shoreline skirting
soakers. High pressure wedge from the e, locations up the me coast
down into northeast ma may end up being the precipitation losers.

End of the week...

series of frontal boundaries, slowing, stalling against the building
wall of atlantic high pressure. Have to watch closely strength of
synoptic features round the convergence boundary, whether there is
the possibility of prolonged outcomes over any one particular area.

Noteworthy is a sudden tick upward of precipitation within ensemble
members.

Aviation 00z Thursday through Monday
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Thursday night ... High confidence.

Tonight...

after 5z, low-endVFR S of bdl-sfz-ghg with MVFR mainly along
the immediate s-coast and islands. Can't rule out a risk of ifr
for ack into Thursday morning. -shra accompanying lower cig
conditions. Some patchy br, the greater likelihood with any MVFR
conditions. Breezy SW winds shifting NW by morning.

Thursday...

vfr. Lingering s-coastal island -shra with MVFR cigs, a brief
threat of ifr CIGS for ack around 12-18z. Improvement during the
afternoon hours, CIGS lifting 4-7 kft agl, as spot -shra develops
across interior S new england around orh. N winds turning ne.

Thursday night...

vfr to start but with northeast flow believe low levels will
saturate dropping CIGS and vsbys to MVFR conditions.

Kbos terminal...

keep -shra S of the terminal overnight.VFR prevailing.

Kbdl terminal...

expect -shra to be immediately S of the terminal. Will go low
endVFR overnight however there is a risk of some MVFR possibly
sneaking in prior to morning.

Outlook Friday through Monday ... Moderate confidence.

Friday:VFR.

Friday night:VFR. Breezy. Slight chance shra.

Saturday through Saturday night: shra likely, chance tsra.

Sunday through Sunday night: breezy. Chance shra, slight chance
tsra.

Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Thursday night ... High confidence.

Passing low pressure system across the southern waters will
bring widespread rainfall which could limit vsbys. Seas could
build to 3 feet. Winds will below 20 kts. Otherwise
southwesterly winds will flip in a more northeast direction
tomorrow lasting into tomorrow night. Could see vsbys
restrictions in fog. Conditions remain below sca.

Outlook Friday through Monday ... Moderate confidence.

Friday: winds less than 25 kt. Seas locally approaching 5 ft.

Friday night: winds less than 25 kt. Areas of seas approaching
5 ft. Slight chance of rain showers.

Saturday: winds less than 25 kt. Seas locally approaching 5 ft.

Chance of rain showers, slight chance of thunderstorms.

Saturday night: winds less than 25 kt. Seas locally approaching
5 ft. Rain showers likely, chance of thunderstorms.

Sunday: winds less than 25 kt. Local rough seas. Chance of rain
