What forecasters said that day
The local office's own words before this heat advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Boston/Norton, MA wrote its last area forecast discussion before this heat advisory went out at Jun 30, 4:08 PM EDT, 8 minutes earlier.
Area forecast discussion, Jun 30, 4:08 PM EDT, 8 minutes before
Area Forecast Discussion
National Weather Service Boston/Norton MA
408 PM EDT Sat Jun 30 2018
.SYNOPSIS...
High pressure along the eastern seaboard will circulate hot and
humid conditions into the region this weekend and likely continuing
into much of next week, featuring highs in the 90s and lows only 65-
70. The coastline will not be as hot thanks to local sea breezes.
Heat and humidity continues through the week. Dry the first half
while a chance of showers and thunderstorms the second half, relief
is possible by the end of the week into the following weekend.
&&
.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
High pressure remains in control of our weather tonight. Expect
rain-free weather and high humidity with min temps 70-75 and dew
points climbing to 65-70. Winds should diminish a little, which
may allow a few areas of fog to develop overnight.
Convection expected to fire near the Ontario/Quebec border late
this afternoon is expected to move over Northern New England
this evening and tonight. With high pressure shifting east, and
based on thickness difluence patterns, we would expect most of
this to remain over Northern New England and possibly sweep over
the Gulf of Maine. Guidance brings favorable conditions rather
close to Northeast Mass for a couple of hours around midnight,
and the SPC HREF Ensemble shows a chance of 40 dbZ radar echoes
crossing into our coastal waters near Essex County MA around
05Z/1 AM. So we have included a 15-20 pct chance of thunder in
Essex County MA. It is possible it could make a quicker turn and
cross more parts of our area at that time, but we will stay
closer to guidance for now.
&&
.SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/...
Sunday...
A hot and humid day. Mixing to 800 mb and temps 17-18C equiv to
21-23C at 850 mb. Will forecast max temps of 95-100F west of
Worcester.
Models continue to show developing easterly winds following the
passage of the convection overnight. This will hold down the
heat in Eastern MA and possibly the Central Hills and RI. The
strength of the wind will determine how much and how far west
this buffering will take place. We will maintain lower 90s away
from the coast and 80s along the coast, but with less confidence
than in the rest of the Sunday forecast.
Based on forecast temps and dew points, the expected Apparent
Temps continue to show at least Heat Advisory criteria in
Western Mass...west of Worcester...and Northern CT. We will
maintain the existing Excessive Heat at this time.
&&
.LONG TERM /MONDAY THROUGH SATURDAY/...
*/ Highlights...
- Early week hot and humid conditions
- Midweek, shower/thunderstorm chances, continued heat
- Relief from the heat possible by the end of next week
*/ Overview...
Not much change from previous runs in the 30/12Z guidance.
Expecting a potent and large mid level ridge to dominate much of
the flow across the USA through most of next week. It appears a
kicker shortwave may develop enough amplified flow to relieve
the heat across southern New England toward the end of next
week.
Expecting dew points to remain in the 60s, with even some lower
70s at times. This will likely result in high heat indices. Will
need to consider Heat Advisories, at a minimum, pretty much
every day this week. There is a lower threshold of 95 degrees
for consecutive days. Not closing the door on Excessive Heat
Warnings at this time, but there is a lower probability of
meeting that criterion.
Ridging aloft should keep the atmosphere mostly capped. It will
really depend upon finer details, such as dew point, to see if
this cap can be overcome. Aspects like that remain a lower
confidence forecast this far out. Increasing risk for showers
and thunderstorms Tuesday into Wednesday as a weak cold front
approaches our region from the north. It still appears the
greater risk is on Wednesday. This potential will need to be
monitored over the next few days.
