MD 1555 CONCERNING SEVERE THUNDERSTORM WATCH 486… FOR PARTS OF EAST CENTRAL NORTH DAKOTA INTO NORTHWESTERN MINNESOTA
Mesoscale Discussion 1555
NWS Storm Prediction Center Norman OK
1127 PM CDT Fri Jul 22 2022
Areas affected...Parts of east central North Dakota into
northwestern Minnesota
Concerning...Severe Thunderstorm Watch 486...
Valid 230427Z - 230530Z
The severe weather threat for Severe Thunderstorm Watch 486
continues.
SUMMARY...The risk for strong to severe wind gusts may still
increase a bit east-southeast of Devils Lake toward the Grand Forks
vicinity during the next hour or so, before probably begin to
diminish east of the Red River after 1 AM CDT.
DISCUSSION...The supercell which passed to the north and east of
Minot has maintained a notable structure the past few hours, on the
southern periphery of slowly organizing cluster of convection now
crossing the Devils Lake area. Cloud tops have still been cooling
with this cluster, and recent radar trends are suggestive that
strong to severe wind gust potential may still increase
east-southeast of Devils Lake into areas near/south of Grand Forks
through 06Z.
Across and east of the Red River thereafter, it appears that the
convective system may begin to process drier/more stable air,
leading to weakening trends and diminishing severe weather
potential.
