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 Binghamton, NY wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 18, 3:46 PM EDT, 35 minutes earlier.

Area forecast discussion, Jul 18, 3:46 PM EDT, 35 minutes before

Area Forecast Discussion
National Weather Service Binghamton NY
346 PM EDT MON JUL 18 2016

.SYNOPSIS...
Scattered showers and thunderstorms ahead of a cold front will
track southeast across the area late this afternoon into this
evening. The front will move east of the area later this evening
with clear weather overnight. Dry warm weather will prevail under
high pressure Tuesday and Wednesday.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
Updated at 330 pm. A cold front is tracking east across western NY
late this afternoon and will cross the forecast area this evening.
One disorganized line of showers and storms has already moved east
of the forecast area this afternoon... and a couple of broken
lines are currently developing over central NY. SPC meso-analysis
is indicating 1000-1500 J/kg of MLCAPE along and east of I-81 with
less than 1000 J/kg to the west over the Finger Lakes. Deep layer
shear ranges from around 35-45 kts with around 20 kts from 0-1 km.
Watch continues into this evening for the possibility that a few
of these storms will become marginally severe, however the
potential for anything more widespread appears to be diminishing.
Once these scattered storms move east of the area later this
evening skies will clear overnight. Northwest winds 5 to 10 kts
and some dry air advection should keep fog from forming. Lows will
fall to the mid 50s to lower 60s.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/... Very quiet
weather during the short term... as high pressure moves across the
area. Tuesday will feature sunshine and noticeably lower dew
points in the 50s with high temperatures ranging from the mid 70s
to mid 80s. A warming trend will begin Wednesday with dry weather
persisting as high pressure moves off the east coast.
Temperatures will be well into the 80s to near 90 on Thursday
afternoon.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
Central NY and northeast Pa will be on the northeast fringe of a
large ridge of high pressure building over the central plains
during the late week through the weekend. Hottest weather will
remain well to our west and south over the central plains but
occasional incursions of very warm weather can be expected ahead
of cold fronts that will be dropping southeast across our area
from the Great Lakes. The first of these systems will drop
southeast across our area Friday night or Saturday bringing a
chance of thunderstorms. Some cooling may occur briefly behind
this system on Sunday but overall the patter appears to be warm
and somewhat unsettled as we go into early next week.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
Scattered thunderstorms will move across central NY and northeast
Pa through early this evening with one or two of the TAF sites
probably seeing a brief period of MVFR conditions with the
passage of a thundertorm. VFR will prevail at all of the TAF sites
after 00z as high pressure builds across the area behind a cold
front. Skies will be mostly clear late tonight and mainly sunny on
Tuesday with noticeably lower dew points on Tuesday. Winds will be
southwest at 5 to 15 kts this afternoon shifting to northwest at
5 to 10 kts tonight and Tuesday.

OUTLOOK...

Tue-Wed-Thu...VFR except for potential valley fog for KELM in
predawn hours Wed and Thu mornings.

Thu Night-Fri...Mainly VFR but there will be a chance of SHRA-
TSRA and associated brief restrictions.

&&

.BGM WATCHES/WARNINGS/ADVISORIES...
PA...None.
NY...None.
