979 ACUS11 KWNS 160757 SWOMCD SPC MCD 160757 MNZ000-NDZ000-160930- Mesoscale Discussion 1288 NWS Storm Prediction Center Norman OK 0257 AM CDT Sun Jun 16 2024 Areas affected...northeast ND into far northwest MN Concerning...Severe Thunderstorm Watch 423... Valid 160757Z - 160930Z The severe weather threat for Severe Thunderstorm Watch 423 continues. SUMMARY...Strong thunderstorms will continue shifting east through early morning. DISCUSSION...A line of storms will continue tracking east near 40 mph the next couple of hours, taking convection across northeast ND into far northwest MN. Measured gusts the past hour or so have typically been less than 50 kt. A southerly 850 mb low-level jet around 25-30 kt ahead of convection, coupled with sufficient instability and deep-layer shear, will maintain organized convection for at least another couple of hours. Instability rapidly wanes with eastward extent into MN as low-level moisture decreases, and storms should weaken as they enter northwest MN. Locally strong/isolated severe gusts of 45-60 mph will remain possible in the short term across northeast ND. A downstream watch and/or aerial watch extension is not expected. ..Leitman.. 06/16/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...FGF...BIS...
