Was on a two day holiday on Lake st. Claire and didn't check the models before heading out. As we were packing up this afternoon, I recognized the edges of (Cb) clouds on the horizon. By the time I got to Chatham, I was witnessing a very large cell moving SSE with another cell forming to its NW. I set up my camera and spent the next half hour recording it's progress until it hit Chatham right on. then for two hours, traveled home to Cambridge video taping the back end of the squall line. Got some great footage that I will have to edit and upload.

Over all, this was a mean storm system. Just watching the wind shear churning the clouds under the rain free base threw my head for a spin. Later on, the lightning made a spectacular appearance as I was heading back. Was a magnificent show that I will not forget.

I chased the same storm and ended up in Forest as the leading edge came ashore from huron. It approached quite quickly and the gust front dropped the temp what seemed like 10 degrees or more instantly. There were branches pdown and a whole tree down on a sideroad north of town. Wind gusts were around 100km. Followed the line south and east right in the middle of the precip and then back across the 401 through some smaller and weakening cells that put on a really good lightshow and made it back to Bradford in time to see the front pass. Was in storms from 7-1030pm makes up for the dry spell lately with he storms. The rain free base was scary looking for sure on this storm it turned quite black prior to hitting. Great day for sure. Can't upload thumbnails from my iPhone now to the site I'm not sure why I have some pics of the storm as it overtakes the town. Darksky it says contact admi istrator if problem persists is there anything I can try to upload these pics from tapatalk?

Buffalo explains why we here in Niagara stayed dry;

LAST NIGHT WAS CHARACTERIZED BY
CONVECTIVE FAILURE FOR MOST OF THE CWA. AN EXPANSIVE OUTFLOW
BOUNDARY FROM AN EARLIER UPSTREAM MCS PUSHED ACROSS MUCH OF WESTERN
NY AND REMOVED SOME INSTABILITY...BUT MORE IMPORTANTLY THE MID LEVEL
OUTFLOW FROM THAT MCS HAS DISRUPTED WHAT LITTLE CONVERGENCE THERE
WAS ALONG THE COLD FRONTAL BOUNDARY. WITH DISORGANIZED FLOW ALONG
THE LOW/MID LEVEL COLD FRONT THERE JUST IS NOT ENOUGH MOISTURE
CONVERGENCE TO GENERATE OR SUPPORT ANY DEEP MOIST CONVECTION.

I did get some lightning strikes over the lake, will try to post later.

Great lightning show here in St. Kitts as the storm passed just out over the lake, but my line of site from the house was blocked by trees/houses, but I could see intense flashing occurring behind them. If I wasn't near-ready for bed I would have gone out to in good positioning to shoot it. Shot some stuff from inside the house (pictures posted in my lightning thread). Great LP storm (no precip here) too.

It would have been great to go shoot it over the lake, but I feel a bit uncomfortable in an open field at the top of a hill overlooking the lake standing next to an aluminum tripod while a lightning storm is going on...

Summary from last night (Saturday, Jul.2) :

AWCN11 CWTO 031557
Weather summary for all of Southern Ontario and the
National Capital Region issued by Environment Canada
At 11:56 AM EDT Sunday 3 July 2011.

-------------------------------------------------------------
==weather event discussion==

 An active 2nd of July...

 A complex of thunderstorms rumbled along a warm front during the 
morning giving very heavy downpours and frequent lightning across 
Southwestern Ontario. Hail was reported by a Canwarn trained
Spotter in the forest city of London.

 In the wake of the morning thunderstorms hot and humid air arrived 
with temperature soaring to the mid thirties over the extreme 
southwest. This set the stage for a cold front to trigger another 
round of strong to severe thunderstorms across Southern Ontario. 
While there was some tree damage in the Fergus area Saturday
Evening, most of the damage reports, mainly from Canwarn
Spotters, was in Essex County. Many areas received torrential 
downpours reducing visibility to under 1 km, gusty winds, and a
Vivid lightning show put on by mother nature.

 Numerous watches and warnings that were issued by environment
Canada have since been ended.

 Severe weather reports received by Environment Canada as of 10.00
AM are in the table below.
