At 4:30 pm radar displayed a rapidly developing thunderstorm approaching Winnipeg from the southwest. A severe thunderstorm warning has been issued for this cell. Radar indicates possible rotation with this storm which may indicate tornadic potential. Very strong downdraft winds and torrential downpours are likely. This storm has developed right along the cold front which is just approaching Winnipeg as of 4:30 pm.
That's turning into a pretty nasty line of storms. Of course although you can get a lot of severe weather with such a line, it does preclude the development of the lone monster supercell, since there is a finite amount of evergy. Usually those F4 and F5 tornadoes are associated with lone supercells that have no competition for atmospheric energy.ReplyDelete
At 7:30, we had an outflow boundary move through Lancaster as the southern end of the storm comples that moved through Winnipeg fell apart. Temp went from 31 to 26 in 5 minutes. Watching a line of tough storms to our west. They finally put out a severe thunderstorm watch for this area (don't know what took them so long).ReplyDelete
Storm came through between 5 and 5:30 pm giving me 16 mm rain, wind gusts to 70 km/h and a few stones of hail. Power was knocked out in my neighbourhood between 5 and 6 pm. Much more comfortable this evening.. a heat-wave ending storm!ReplyDelete
I collected 16 mm of rain in River Heights. It was a lively storm, but nothing destructive happened in my neighborhood. Compared to the monster storm of July 16, 2005, it was a walk in the park.ReplyDelete
