Areas affected...portions of northwest Minnesota
Concerning...Tornado Watch 306...
Valid 072230Z - 072330Z
The severe weather threat for Tornado Watch 306 continues.
SUMMARY...The tornado threat has largely ended across portions of
northwest Minnesota. Tornado Watch 306 will expire at 23z.
DISCUSSION...A weakening trend has been noted on radar observations
over the last hour as a line of storms continues to track east
across northwestern MN. Increasing boundary layer stabilization with
loss of daytime heating will continue to stabilize the boundary
layer. Additionally, weak instability with MLCAPE values around
250-500 J/kg will further limit robust convection into the evening
hours. Given the decreasingly favorable environment, a downstream
watch is not expected and WW 306 will expire at 23z.
