Over the last 3 days, temperatures have ended up about 1-2 degrees below normal. Then all of sudden, we’re really hot today! As well, tomorrow will possible be cooler than the weekend, and we might reach back to the 20s again on Friday!
If you read the previous post, you would probably know why we’re so hot today. We had a trough that came through and cooled thing down, but now a weak ridge has come. As well, we will have an approaching trough behind this ridge break off and become a cut-off low off the coast of the northwest US. That low is not entirely escaping though, because part of it will split off and track over northern Alberta. This other low, currently in northeastern BC, is partly the reason we’re so hot. It’s bringing up warm air from the south with its counter-clockwise winds. This low will generate a cold front, expected to pass through sometime tonight. It might bring a shower or two, but most, if not all, of the precipitation will be to the north and west of here.
Because of that front, we’ll be much cooler tomorrow, with a high of 10-12. The low Wednesday night looks likely for frost. However, after the low cuts off, we’ll end up back in warmth. We’ll start with a high near-to-slightly-above normal on Thursday, then maybe back all the way to 20 again on Friday.
After Friday, there will be a strong cold wave, but if you want to know more about that, check out the previous post.
