What forecasters said that day
The local office's own words before this river flood 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 river flood warning went out at Jul 13, 7:14 PM CDT, 1 hour 56 minutes earlier.
Area forecast discussion, Jul 13, 7:14 PM CDT, 1 hour 56 minutes before
Area Forecast Discussion National Weather Service Grand Forks ND 714 PM CDT Mon Jul 13 2020 .UPDATE... Issued at 702 PM CDT Mon Jul 13 2020 Lead surface trof has pushed to an FGN-FSE-DTL line with a trailing cold front still back in central ND. Severe threat is mainly ahead of that surface trof line, and into northeastern MN... tho widely scattered thunderstorms are still possible across eastern ND into the late evening. Meanwhile, a few strong storms are ongoing in eastern Polk, Clearwater, and Mahnomen Counties. && .SHORT TERM...(This evening through Tuesday night) Issued at 343 PM CDT Mon Jul 13 2020 Monitoring severe threat this afternoon/evening (see mesoscale discussion for severe potential/impacts). Increasingly complicated forecast as a result of more extensive stratus within WAA and stable low level lapse rates that were handled poorly by guidance. Strong forcing/WAA still supporting at least clusters of showers/storms the rest of this afternoon in ND before transitioning into MN and out of our CWA through mid evening. Heavy rain rates already observed and back-building clusters continue to support excessive rainfall potential where activity tracks through this evening. After the main upper trough axis shifts east a secondary lobe of positive vorticity advection moves south of our CWA and elevated showers/storms may redevelop into the southern half of our CWA late tonight into Tuesday morning. At that point instability will be much less and we are not expecting strong/severe potential beyond this evening. After any lingering showers/storms end early Tuesday morning we should see a less favorable pattern for convection, though there is a weak signal for diurnally driven showers/storms (limited instability so not expected to be strong).
