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 State College, PA wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 3, 3:40 PM EDT, 1 hour 3 minutes earlier.

Area forecast discussion, Jun 3, 3:40 PM EDT, 1 hour 3 minutes before

Area Forecast Discussion
National Weather Service State College PA
340 PM EDT Wed Jun 3 2020

.SYNOPSIS...
Additional showers and thunderstorms will be quickly forming
late this afternoon into this evening across the northern half
of the state and will drift into southern PA early this evening
as a frontal boundary pushes through the state. It will remain
unsettled Thursday into Friday, and possibly right into the
weekend. High pressure and dry air take hold Sunday and lasts
into Tuesday.

&&

.NEAR TERM /UNTIL MIDNIGHT TONIGHT/...
The nose of MU capes exceeding 2000 J/KG is nosing into the NW
mtns attm and the airmass is recovering quickly after this
morning's widespread showers and strong to svr tsra.

Showers and scattered strong TSRA were firing rapidly within
this region of increasing instability. 0-1km were EHI's were
between 1-2 M2/S2 across much of our central and western zones,
with 0-1km bulk shear between 20-25 KTS. LCL heights were also
only 750-1000M over roughly the NW half of the CWA.

The blossoming area of convection will sink right through the
current SPC Day 1 Slight Risk area for svr and strengthen over
the next several hours. By 00Z Thu, the broken line of strong
to SVR convection will be across the southern 1-2 layers of PA
counties, and sink south of the Mason/Dixon line around dark.

Temps have rebounded into the low-mid 80s across all but the
northern tier with sfc dewpoints mainly in the mid to upper
60s.

Westerly winds will continue to gust into the teens and 20s
over the SW/SC ahead of the expanding area of TSRA fueling SR
inflow.

&&

.SHORT TERM /MIDNIGHT THROUGH 6 PM THURSDAY/...
Storms should still be going early this evening in the southern
third of the area. Clearing will spread south across the region
late tonight, but may self-destruct and turn to some fog.

Low clouds are also possible where the wind is an upslope
(Alleghenies). Storms/showers will diminish for everyone but
they could hang on until around or shortly after midnight across
the Laurels. Sticky air will keep the temps from falling out of
the mid 60s for about half of the area, though some clearing
will allow the nrn mtns to dip into the 50s.

The old boundary will likely be along the srn border Thurs
morning, the sfc wind will be light and SWrly. Upper flow
flattens to a W-E direction, and lingering moisture and daytime
heat will lead to showers and storms in the aftn. The shear will
be lacking, but CAPEs could reach 1000 or better across the
south. So, a few of the storms could go severe, but most likely,
without the shear, many will be sub-severe. SPC MRGL risk is
enough to keep a close eye on them. Maxes Thurs will be just as
warm across the north than the south, thanks to more sun up
north. The coolest place will be the Laurels where clouds and a
higher chc of showers exist.

&&

.LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/...
The old front will stall near the PA-MD border on Thu, keeping
a chance of rain showers and maybe a few PM tstms through Fri.
Generally a quarter to half an inch of rain is expected across
the southern counties Thu-Fri, with locally higher amounts in
storms. Lesser amounts north.

The stationary front is progged to move offshore Fri night, with
slightly drier air moving in for Sat. Another cold front and
shortwave trough may touch off isolated showers/storms Sat, but
drier air will be a limiting factor. Cooler, drier air will move
in behind this front for Sun-Mon. We will see a warming trend
into the middle of next week as the remnants of TS Cristobal
moving up the MS valley help build an upper ridge over the
eastern US.

&&

.AVIATION /19Z WEDNESDAY THROUGH MONDAY/...
A second round of scattered showers and t-storms will develop
across parts of the airspace late this afternoon through early
tonight. Outside of t-storms, expect mainly VFR conditions to
prevail during the 03/012Z TAF period. Some patchy fog is
possible in the northern tier late tonight into early Thursday.

Outlook...

Thu...Showers/t-storms likely especially srn 1/2.

Fri-Sat...Chance of showers/t-storms.

Sun...VFR/no sig wx.

None.
