What forecasters said that day

The local office's own words before this special weather statement 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 special weather statement went out at May 28, 3:36 PM CDT, 47 minutes earlier.

Area forecast discussion, May 28, 3:36 PM CDT, 47 minutes before

Area Forecast Discussion
National Weather Service Grand Forks ND
336 PM CDT Sun May 28 2017

.SHORT TERM...(This evening through Monday)
Issued at 335 PM CDT Sun May 28 2017

Potential for scattered thunderstorms with frequent lightning,
small hail, and strong wind gusts remains through early evening
as effective shear with values from 25-40 kts in southern/western
zones of the forecast area combine with surface based
instability, a southward-moving mid level impulse aloft, and 850
jet streak.

Chances for thunderstorms will dissipate through the evening from
north to south, as shear and instability weaken and forcing moves
south out of the area. The strong upper low, currently in
Manitoba, moves into northern Minnesota tonight and works into the
Great Lakes region by morning, causing scattered showers to stick
around through the overnight hours.

As several weak impulses push around the upper level system, breezy
and cloudy conditions and chances for scattered light showers will
continue through Monday night. Cloudy skies, close proximity to the
upper low, and breezy northwest flow will make for a cool day
Monday, with highs only reaching the 50s to lower 60s and lows in
the 40s Monday night.

.LONG TERM...(Monday night through Sunday)
Issued at 335 PM CDT Sun May 28 2017

The 500mb low will continue to hold over the Great Lakes on Tuesday,
keeping a chance of showers around, mainly over northwest and west
central Minnesota. With abundant cloud cover across most of the
area, look for one more day in the mid 50s. If the western FA can
manage to get a little sun, they may be able to poke up into the low
to mid 60s. Northwest winds may still be a little breezy through the
afternoon too.

For Wednesday through Friday the region will be under northwest flow
aloft. Most of this time frame will be pcpn free, but chances do
finally pick up again by Friday and Saturday. At this point there
is still quite a bit of difference between the models on the timing
on this next round of pcpn. Some models even dry things out before
it moves into the FA, so hopefully later model runs come into better
agreement. With the uncertainty, pcpn chances are only in the
isolated to scattered range for now. These uncertainties play into
Sunday as well, with some models still showing pcpn while others
are dry. The good thing about the Wednesday through Sunday time
frame is that temps are finally expected to rebound back toward
early June normals.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1259 PM CDT Sun May 28 2017

Expect mostly low VFR cigs today, with some MVFR cigs associated
with scattered showers and thunderstorms across the area this
afternoon. Strong NW winds with gusts at 30-35 kts possible this
afternoon, especially in the DVL-FAR corridor. Showers and storms
will diminish this evening. MVFR cigs will spread through NW MN
overnight with possible IFR cigs along and north of a TVF-BJI line
overnight.
