It's a big day everyone.Not only is it the summer solstice and the longest day of the year but it's the start of a new season summer. And summer is kicking off on a high note in the southern N.W.T., literally, with excessive heat warnings.

So, it's going to be a bit of a scorcher out there.

Hot first day of summer

Excessive heat warnings as issued Friday by Environment and Climate Change Canada. These warnings are for temperatures above 29 C. (Bradlyn Oakes/CBC)

In the N.W.T., excessive heat warnings are issued when daytime high temperatures are set to be 29 C or higher. We saw this happening yesterday already, will continue through the day today and for some areas even into tomorrow. These high temperatures do pose a risk to health, especially through prolonged exposure.

Forecast highs in the thirties

Heading through the day today, temperatures look to get into the low thirties. The highest temperatures will be felt in Wrigley and Fort Providence, where current forecasted highs are inching toward the June 20threcords. Wrigley's June 20th high record was 30.9 C from 2013.

Into Sunday, heat moves a little further east, away from Wrigley and Fort Liard, but still through the North and South Slave regions. This again, brings the possibility of record-breaking heat for June 21, particularly in Whati and Fort Providence.

The weather maker here

Warm air is over the N.W.T., which is sending those thermometers up. This comes from a broad upper ridge that is pushing the territory to drier conditions, as well as those temperatures six to ten degrees above normal.

But under this upper ridge, there is also the potential for some thunderstorm activity and even a spotty shower. This is especially true to the west of this system. Our thunderstorm risk today includes Fort Simpson, Fort Liard and Nahanni Butte.

Protect yourself from the heat

Heat, like any extreme weather event, can cause harm. So, while we're all out enjoying the nice weather, let's remember to ensure we stay hydrated, use that SPF, wear a hat and head indoors if you get too hot.

Stay safe, and have a happy start to summer everyone!
