Flames game day forecast: You may want to bring a red umbrella

UPDATE: The way this system is developing, Calgary's not out of the woods on rainshowers yet.

Firstly, there are two images below; the first is what's expected Friday morning, but with that system popping free of the foothills, Calgary gets a chance of showers this evening; light stuff, as we cool off, somewhat. If you're planning on taking in the Flames game somewhere out-of-doors, that's worth considering. Yesterday's modeling had this setup further north; while a chance for 1-3 mm is in the immediate forecast, it's spread out over six plus hours.

For the weekend, there's still a wide spread among forecast models, but I'm comfortable suggesting over 10 millimetres will fall between Saturday afternoon and midnight Sunday. Spotty showers still exist beyond then, as well. Most of this is pulled free of the foothills.

We may also run into periods with mixed precipitation. Low temperature trends have started improving, however, so that chance is presently quite remote.

It's time for the Thursday edition of "How Warm Today, And How Much Rain This Weekend?" The answers to these questions are 22 C, and… less than previously predicted.

Let's break it all down.

A number of forecast models pin today squarely on a high near 20 C, but we're still coping with warm wind. Today it rises from the south instead of yesterday's westerlies, which popped sections of the city to 22-23 C. Still, that's a contributing factor to the high, though it will involve gusts to at least 40 km/h, with a chance we crack 50.

Ditto Friday, but with a directional shift back to westerlies.

So what's changing, again, for precipitation? Here's the early Friday look:

So that low bursts onto the scene tomorrow morning. It'll help create westerlies for us. There's a wildly small chance of showers late Friday from it. But that’s not the low we’re interested in; this is:

The expectation is that this one (which would arrive on the Saskatchewan-Manitoba boundary Sunday morning) would be grabbing moisture off the foothills and throwing it at us. This one was projected this week to form in Montana before swinging to the north-northeast. The previous track took longer – it's moving a lot more rapidly now, which limits the impact in southern Alberta. It's a small change, but it's further proof that forecast models don’t like mountains, much.

The Saturday forecast is not completely dried out, but as we close in and models verify, we're down from "rain" to "chance of showers." Not great.

Sunday still runs a shot, and so does Monday. Now, we're peaking at 15 millimetres, but likely closer to eight mm.
