July 2015 will end up as the hottest July since 2007 (in Edmonton).
We're a little more than 2 degrees warmer than the 30-yr average and August will start warmer than average too.
Daytime highs in Edmonton will be in the mid to high 20s for the next 4 days.

An upper ridge should keep most of Central & North-Central Alberta storm-free today.
As that ridge pushed in...there WERE some thunderstorms that pushed through areas just north & NE of Edmonton after midnight last night.
Fort Saskatchewan saw some of that action & parts of Edmonton woke up to the lightning & thunder.

We can't completely rule out an isolated thunderstorm in the foothills or the Peace Country tonight.
But, MOST areas stay dry today & tonight.

The ridge looks like it might slip south A BIT Saturday & that may help to generate a few thunderstorms.
There really doesn't look to be much of a driver for storms.  But, if a storm develops in the foothills, it could drive east with some strong wind aloft.

Bottom line:  Storms aren't overly likely for any given city/location.  
BUT...various REGIONS have a better chance of seeing a storm somewhere within that larger area.
The most likely "regions" for thunderstorms this weekend are the Foothills & Peace Country Sat/Sun/Mon.
Elsewhere, enjoy the heat this long weekend.  
If you're at the Servus Heritage Festival...the storm risk is very low & if anything does develop, it'll likely be after closing for the evening.
Big Valley Jamboree - hot & partly cloudy for most of the weekend.  But...keep an eye on the sky.  There IS a risk of a late-evening storm, especially Sat & Sun.
