At the moment, the jet stream is kind of all over the place. Roughly though, it’s overhead-ish.
As we look into the week, we can see lots of storm potential. In fact, every single day for the rest of this week probably has an >30% chance of us getting a thunderstorm. This is because of the same reasons of all other stormy days we’ve had in the last month or two. We have warm and cold air mixing together and creating instability, a close jet stream, and no blocking patterns.
A thing that will be paired with the storms this week is more low 20 highs, like a lot of what has happened so far this summer. The ridge will move eastward, and a through will come in its wake. It has already appeared in northern BC, and will dig its way down all the way to Montana this week, and will likely cool temperature down by about 5 degrees, starting Wednesday. The low will also bring clouds, so the second half of the week, mainly Thursday and Friday, will see semi-overcast skies.
Now what about precipitation? Just like what we had over the weekend, most of it is going to be from storms. This means precipitation will be very variable, just like how in the last 48 hours Stony Plain got over 20 mm, while my house probably got about 1.
That is it for today. If you want more details, just wait for my email forecast this evening. If I end up busy, then maybe tomorrow evening.
