KNUTSVIGWhat 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 Aug 18, 3:49 AM CDT, 3 hours 8 minutes earlier.
Area forecast discussion, Aug 18, 3:49 AM CDT, 3 hours 8 minutes before
Area Forecast Discussion National Weather Service Grand Forks ND 349 AM CDT THU AUG 18 2016 .SHORT TERM...(Today and tonight) Issued at 349 AM CDT Thu Aug 18 2016 Short term period primary threats include flash flood potential this morning and severe threat later today. The latest analysis indicates an area of 2000 J/kg of MUCAPE exists over south-central ND currently. Further north and northeast into NE ND...MUCAPEs of around 500 exist. A 25-35 kt low level jet is helping keep thunderstorm activity going this morning. This jet, along with the theta-e associated with the high MUCAPEs, will shift east this morning as a low in the western Dakotas shifts east as well. Frontal boundary across the north is being reinforced by the cold pool associated with current thunderstorm activity in that area and can be seen moving south as a fine line on radar. Recent WPC meso precip discussion points out flooding potential exists as this system shifts east into the Red River Valley this morning...all the way down to the southern valley. Will mention flooding/heavy rain threat in HWO and also in grids. Thunderstorm activity this afternoon will be dependent upon this morning's activity. Current thinking is that the southern part of the valley could see severe activity this afternoon/early evening. The last two runs of the HRRR point toward this morning's activity moving through Bemidji by noon...with redevelopment /possible/ behind this line near Fargo/Wahpeton into the late afternoon hours. .LONG TERM...(Friday through Wednesday) Issued at 349 AM CDT Thu Aug 18 2016 Friday looks quiet with cool high pressure building into the region under cloudy skies. Clouds decrease for Saturday...but cool air will linger with highs only in the mid 60s to lower 70s. Long wave upper level trough over Hudson Bay shifts east while long wave ridge over the Gulf of AK shifts into western Canada by the end of the period. The long wave pattern de-amplifies through the period. The GFS and the ECMWF were in good agreement through the period with the GFS a little faster on MON then syncs back up by the end of the period. The ECMWF was trending faster while the GFS was vacillating around in the Mon time frame. Will blend the models. High temperatures were increased a degree or so on Sun. Temps were increased two to three degrees for Mon and one or two degrees for Tue. High temps decreased one to two degrees for Wed from yesterdays forecast package. && .AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon) Issued at 1252 PM CDT Wed Aug 17 2016 VFR conditions this afternoon and tonight, with VFR cigs lowering through the morning as SHRA and TSRA being spreading across the area. Convection may impact DVL and GFK through 18Z and will likely not impact other sites until later Thu afternoon. && .FGF Watches/Warnings/Advisories... ND...None.
