"Pop Up Outflow Storms"

begin.jpg (37214 bytes)

Well it all started just after 3:30 when the cells really start to get going and were running North of the GTA. My cousin and myself were rushing up Bathurst street to get out of the city ASAP.
allan.jpg (22205 bytes) When on the Allan north it was another battle of direction. Should we take the 401 to 404 or take the 400 to Major Mack. I ultimately won the debate.
401.jpg (14995 bytes) I had totally forgot in the process that it was early rush hour and we were soon slowed to a 50km/h pace and were forced to literally yell at people to start driving. Finally 1 lane became free and all was moving well until some guy jumped in from the right lane and slowed us to a crawl of 80km/h. At this point I was gonna get out and kill him!
anvil.jpg (8119 bytes) While still heading east some anvil debris was seen our way.
404.jpg (11008 bytes) We finally made it to the 404 and raced North to play catch up with the storm which was already north of Stouffville.
4042.jpg (11055 bytes) Nearing Stouffville road. The cell by this time was well NE so we really had to push it.
rain.jpg (13033 bytes) At this point we were getting prepared for some heavy precip and it was pretty dark but even so drizzle was all that was falling.
edge1.jpg (12686 bytes) We were actually on the western flank of the storm at this time and it was much farther north than estimated so we actually ran right to the end of the 404 and were forced to turn around.
cell.jpg (14046 bytes) Heading south again we knew it was impossible to catch the storm we were after but I was instant to get some pics. So we exited at hwy 9.
dark_line.jpg (10147 bytes) That was when this amazing low level meso appeared. Although hard to see since the cloud base was so dark there was clear slow rotation at the base that was well defined however the outflow which had caused it to rotate also was cutting it off, so we decided to follow the outflow boundary and see if anything else would fire.
wallcloud_draw.jpg (12252 bytes) That's where the base of the wall cloud was. Look above and compare then you should be able to see it.
rain2.jpg (14304 bytes) While heading west along the outflow on hwy 9 storms did fire.
2nd_wallcloud.jpg (15493 bytes) As we were driving towards this developing cell we passed through the precipitation swath from the parent cell which dropped an amazing amount of rain that was still present 20 minutes later after it had passed this area.
cell2.jpg (10829 bytes) We watched the cell get organized and followed the 400 south through King City..
rain3.jpg (17418 bytes) It was clearly well defined and did have a very flat base. Lightning was also present within the cell and there was a cg.
die.jpg (14856 bytes) Shortly after the cell began to die and we gave up and headed home.
drive_home.jpg (26782 bytes) Heh.. rush hour when we start rush hour when we end..
radar1.jpg (35647 bytes) Not a bad cell at its peak.
sat.jpg (24512 bytes) Can see some overshooting tops here.
