Warm to start, but rapidly cooling in Calgary tonight

UPDATE: Tuesday of next week is in the forecast. That's, uh... that's going to really be something.

But enough about that.

The high today DID make it up! We briefly popped to 10 degrees, our only such instance of it for the week, and it lasted one hour before that northern air cycled in and wagged a finger. Gusts from the northern air topped at 47 km/h this afternoon, but in all likelihood, we aren't done with those gusts yet (as of this writing), and overnight temperatures are likely going to spill into a few fog advisories, including Calgary, for a commute tomorrow morning that will already involve overnight freezing. Lots to watch out for. Give yourself extra time on those roads.

Otherwise, the temperature trend suggests Friday will be a little more aggressive with the overnight warming, then Saturday and Sunday and Monday are laden with high pressure, covered up in sunshine, and looking fine.

 

Today, a new wave of high pressure will begin to settle over us. Before we actually fall beneath it, we have to allow for its arrival; that will make for a large wave of cool air out of the north striking out and blasting through our region this afternoon, and may trigger weak snow showers for this evening. Wind gusts are likely topping the 40 to 50 km/h marker as this moves through. As for its arrival time, the expectations are still variable, but close to 3 p.m. is my best estimation at this time – yesterday, it was a touch further back in the day. That means that our high temperature, including my call just yesterday of 8 C, is less likely to manifest.

Regardless, we'll have another round of reasonably solid melting for the day, followed by a perfect opportunity for an overnight freeze. Friday’s roads could be particularly treacherous.

Then, the high pressure builds… slowly. The northern wind will knock our low temperature to the chilliest negative we've seen in a while – though it still bears no resemblance to the cold snap we just went through. Tomorrow will be consequently milder, with warmer conditions building as the day wears on. Your daytime high is milder, still.

Saturday, we're back to what’s become familiar, and waver along this above-seasonal trend for a while under a clear sky.
