What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Gray, ME wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 1, 7:35 PM EDT, 33 minutes earlier.

Area forecast discussion, Jul 1, 7:35 PM EDT, 33 minutes before

Area Forecast Discussion...UPDATED
National Weather Service Gray ME
735 PM EDT FRI JUL 1 2016

.SYNOPSIS...
A cold front will cross the region overnight with showers and
thunderstorms. High pressure will build in from the west over the
weekend and last into mid next week. Temperatures will be on the
rise next week.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
735 PM Update...
We have issued a severe thunderstorm watch for southern and
central NH in coordination with SPC. Adjusted weather grids based
on the watch and timing of the storms as they move east. Generally
not expecting severe storms over Maine as the night wears
on...although strong thunderstorms with plenty of lightning...
torrential rainfall...and gusty winds may affect boaters...campers
and people on the lakes and shores tonight.

615 PM Update...
Thunderstorms are now beginning to move into NH...with a
significant short wave now moving in aloft. A quasi-warm front is
lifting north over southern NH. Dew points have mixed out into the
50s across much of northern and central NH. Across portions of the
coast and inland...the marine layer has also brought thunderstorm
chances down.

This leaves the most likely area for isolated severe storms over
southern NH as the line of storms attempts to congeal/develop a
cold pool. Still expecting at least one and possible two broken
lines of convection to push through NH and across all of Maine
overnight. Areas to our southwest have been tracking supercells
over the last few hours. So far these storms have produced large
hail and damaging winds as well as rotation. The timing of the
storms may not be the best so expect more of a multicell mode with
some rotation for our area.

Max T and diurnal temperatures were adjusted for current
trends. Thunderstorm attributes were left alone at the moment but
may be revisited lated to adjust severity wording.

Previous discussion...
Showers and thunderstorms will cross through the area tonight.
Latest HRRR model show the main area of storms entering NH from
the southwest about 6 pm...then spreading northeastward through
the evening crossing into ME about 8 pm. Most of NH remains in
SPC's slight risk area...and a few storms in that state will have
the potential to be severe with damaging winds. The storms should
weaken a bit as they move into ME due to the lack of diurnal
heating and a less favorable environment...but could still produce
rather gusty winds. All areas will see potentially deadly
lightning and anyone planning to be outside should be ready to get
inside a safe shelter if thunderstorms threaten.

The storms should move east of the region by morning with clearing
across southern areas.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/...
Following the front...skies will be partly to mostly sunny across
the region with temps ranging from near 70 in the mountains to the
lower 80s southern areas. Winds will be gusty throughout the day
with gusts most areas near 20 mph. The mountains will see more
clouds throughout the day and can't rule out a passing shower.

For Saturday night...winds should diminish leading to a mostly
clear cool night with temperatures dropping into the 40s and 50s.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
Generally fair and dry weather looks to be in the cards Sunday
through much of next week as troughing is replaced by ridging. A
few showers will be possible in the mountains Sunday, but
otherwise dry weather is looking likely for much of the area
through at least Wed. Warming temperatures, perhaps even hot,
looks likely for midweek.

&&

.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/...
Short Term...vfr to MVFR conditions this afternoon will become IFR
this evening in showers and thunderstorms. Conditions will
improve to VFR Saturday morning and remain vfr saturday night.
Mountain areas could see some MFR conditions in showers Saturday.

Long Term...We expected VFR conditions Sunday through Wednesday.

&&

.MARINE...
Short Term...A small craft advisory is in effect for all of the
outer waters overnight and the waters east of Portland for Saturday.
All areas...including the bays...could see gusty winds in
thunderstorms overnight.

Long Term...Expect winds and seas to remain below SCA criteria
Monday through Thursday. Low probability of SCA conditions on
Sunday on the outer waters as low pressure departs.

&&

.TIDES/COASTAL FLOODING...

&&

.GYX WATCHES/WARNINGS/ADVISORIES...
ME...None.
NH...None.
MARINE...Small Craft Advisory until 6 PM EDT Saturday for ANZ150-152.
     Small Craft Advisory until 6 AM EDT Saturday for ANZ154.
