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 for stonington me to merrimack river ma out to 25 nm.. Southwest flow will continue through this evening ahead of an approaching cold front before shifting to the northwest before daybreak Tuesday. High pressure will build into the region on Tuesday and persist into Wednesday before a cold front arrives Wednesday night.

Synopsis
Hot temperatures and high humidity will give way to much cooler
and drier air as a strong cold front moves through the region
tonight. Ahead of this front... Strong to severe thunderstorms
are expected. Gusty northwest winds will arrive on Tuesday with
dry and seasonable conditions for the remainder of the week.

Near term through tonight
High impact weather potential: high heat indices along with
severe thunderstorms through this evening. Areas of fog possible
overnight.

Through this evening: severe thunderstorm watch 187 has been
issued as significant warming moistening of the low level
airmass has occurred in the past 2 hours with convective line
associated with pre frontal trough strengthening as a result.

Our 18z balloon shows somewhat better than expected lapse rates
into the mid levels with moderate-strong deep shear... Some low
level turning... And increasing MLCAPE values. Thus... Not at all
surprised at rapidly developing convection and expect all areas
south and east of current line to be at risk over the next 3-6
hours. Primary threat is damaging winds... But see below for
additional threats.

Tornado threat: storms thus far have already exhibited
impressive rotation with two tornado warnings issued. Low level
helicity values are modest... But clearly sufficient and thus an
isolated tornado threat will continue through the next few
hours.

Hydro: while the convective parameters have improved... The pwats
are also increasing with 2-2.25 inch values now pulling into the
region from the west. As pre-frontal trough sags south... It will
increasingly become aligned with the mid level flow with heavy
rain becoming an increasing threat.

Tonight: expect showers and embedded thunderstorms to continue
through the first half of the overnight before coming to an end
behind the front after midnight with low level flow shifting
northwesterly. Fog is likely given the evening rainfall with a
warm and muggy night expected as lows fall into the 50s north of
the mountains... And the 60s to around 70 south of the mountains.

Short term Tuesday through Tuesday night
High impact weather potential: minimal
Tuesday: much quieter day on Tuesday as shortwave trough axis
pulls east with surface high pressure building into the great
lakes. Strong cold dry advection will continue through the day
as continental polar airmass works into the region. Winds will
likely be the primary impactful weather element given modest low
level gradient and the aforementioned cold advection. Followed
closer to warmer drier mav guidance due to recent performance in
these scenarios... Which results in highs in the 70s north to
lower 80s south along with dewpoints falling into the 40s during
the day.

Tuesday night: high pressure builds overhead with decoupling
winds and dry airmass likely to result in near ideal radiational
cooling conditions. This will result in a much cooler night than
the one previous with perhaps some fog over lakes and rivers as
lows fall through the 40s north and lower 50s south.

Long term Wednesday through Monday
A cold front is agreed upon by several deterministic and
ensemble sources to move through the region Wed or Wed night.

This front will introduce a cooler and drier air mass which
should peak Thursday night with lows in the 40s... With perhaps a
few upper 30s readings at the best radiators across northern nh.

High pressure is expected to slide offshore Friday allowing for
a warmer and more moist return flow to set up through the
weekend. The best chance for showers and thunderstorms will be
Sunday as a short wave trough and attendant cold front
approaches northern new england from the west.

Aviation 18z Monday through Saturday
Short term...

vfr at the moment through the terminals. Current expectations
are that a line of storms will impact the terminals in the
20-23z timeframe with showers and embedded thunderstorms behind
this initial line. Overnight... Expect some stratus and fog
development before clearing arrives Tuesday morning behind the
departing cold front. Much drier air arrives with high pressure
Tuesday with northwesterly winds of 14g22kts.VFR conditions
with diminishing winds continue through Tuesday night.

Long term...

vfr conditions are expected to be prevalent through the period.

However, there could be a period of MVFR conditions Wed wed
night in association with a cold front. Also, as moisture
increases Saturday and Saturday night, some low stratus could
affect the coastline.

Marine
Short term...

scas outside the bays through 12z Tuesday. Northwesterly winds
gusts will near 20-25kts for a time on Tuesday... But then
quickly diminish Tuesday night.

Long term...

marginal SCA conditions will be possible in
southwesterly flow in advance of a cold front Wednesday
afternoon. Otherwise, the next chance of SCA conditions comes
over the weekend in advance of the next frontal system.

Gyx watches warnings advisories
Me... Heat advisory until 7 pm edt this evening for mez018-019-023-
024.

Beach hazards statement until 8 pm edt this evening for
mez023>028.
