I just caught the CBC article about it. They noted it was in central Winnipeg, and cited 3 possibilities: 1) meteorite; 2) lightning strike; 3) arcing at the Scotland Ave Manitoba hydro substation (near Stafford and Grant). They noted that MB Hydro said there was arcing at that station around that time. If that was the case, it must have been quite a flash, as I'm about 2.5km away from there and the sky was lit up, but I suppose it's possible.<br /><br />(I too looked at the public 0400 UTC and then later the 0500 UTC lightning detection page and saw no strikes, which is why I was querying if they capture all discharges)<br /><br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-33386160.post-14737171070372656162013-01-16T16:03:46.322-06:002013-01-16T16:03:46.322-06:00I ran our lightning plot from last night, and didn...I ran our lightning plot from last night, and didn't see any strikes anywhere in southern MB last evening.

When you go on the Winnipeg page on EC's site and go at the bottom where it says 'yesterday' it gives the temperatures and precipitation from the 'A CS' station. Is this A CS station the official station now?? The precip amounts and temps are not the same as the awos station which we've been considering as official for a while now. <br /><br />Unfortunately, I don't think this A CS station has better precip amounts. An example is that this station only reported 0.4 mm of precip on March 2, 2012.
