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 Grand Forks, ND wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 12, 3:23 PM CDT, 2 hours 36 minutes earlier.

Area forecast discussion, Jun 12, 3:23 PM CDT, 2 hours 36 minutes before

Area Forecast Discussion
National Weather Service Grand Forks ND
323 PM CDT SUN JUN 12 2016

.SHORT TERM...(This evening through Monday night)
Issued at 323 PM CDT Sun Jun 12 2016

This forecast discussion will be brief due to severe weather
potential later this afternoon into the evening. The main forecast
challenge is the severe weather potential. The surface low is over
southeast ND with a warm front extending down into SW MN and
a cold front extending back into central SD. These will be the main
boundaries to watch this evening. SPC day 1 outlook has all of
eastern ND and all of our NW and WC MN counties in a slight risk,
with the high resolution models kicking storms off by mid to late
afternoon and lasting into the evening. Main threats appear to be
large hail and damaging winds, but with the sfc low in the vicinity
a few tornadoes cannot be ruled out. The region is also mentioned in
the excessive rainfall discussion, which talks about the dry weather
of late making flash flood guidance high in some areas as well as
that storms are expected to be progressive. Most high resolution
guidance has the storms exiting the area by mid to late evening.
Monday then looks quiet with high pressure overhead.

.LONG TERM...(Tuesday through Sunday)
Issued at 323 PM CDT Sun Jun 12 2016

The next wave lifts up into the FA on Tuesday and brings chances for
pcpn Tue into a part of Wed. The entire FA is in general thunder for
this time frame, with better chances for severe over the Central
Plains.

For Wed night through Sunday...Active pattern on Days 3 and 4
settles down by Wednesday night into Thursday, with SW flow
pattern aloft and increasing POPs returning Friday night into the
weekend. This will give the region chances for convection
throughout the weekend. Temps will generally be in the 80s, with
the coolest day on Thursday.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1245 PM CDT Sun Jun 12 2016

VFR Conds this afternoon however convection will start by mid-
afternoon, mainly SW of Fargo and push northeast through the late
afternoon into early evening.  Activity will dissipate by mid to
late evening, however models showing MVFR cigs sinking into region
after midnight, mainly east of the valley.  Will keep mention of
MVFR limited to BJI at this time.
