Cold front for Calgary Wednesday brings wind, possible showers
AFTERNOON UPDATE: Here it comes...
Otherwise, the forecast still reflects the effect this will have tonight; the low temperature margins have been pretty spot-on thus far, which should mean a single-digit low again Wednesday evening. As this passes through, there's been a chance for isolated thundershowers; that remains, and also remains most likely north of us.
Lastly, our Sunday high temperature, while ranging quite high on some models, has dropped back to a more reasonable level. It'll be a warm weekend, all the same.
MORNING EDITION: With our overnight temperature dropping steadily, many Calgarians will wake up to smokier weather today. The layer of haze that settles in will likely stick around for a portion of the day, with the Firesmoke model projecting a clear-out later this afternoon as part of a wind setup from the north, and the return of wildfire smoke again this evening. The current Air Quality Health Index rating for parts of Calgary is between a 3-4, and south of Calgary, near Okotoks, it's closer to a 7.
That wind setup, in question, is a cold front. At this time, the expectation from this frontal passage is a mid-to-late afternoon drop in temperature, an increase in winds to the mid 40 kilometre per hour range, and a slight chance from this for showers or even an isolated thundershower to develop. The potential for this is quite low, but non-zero. The cold air mass pushing through will elevate much of our surface smoke.
Once the frontal passage clears, we hit the ridge's entrance-region:
Airmass bringing cooler temps to Alberta.
Following those red arrows, we see our airmass getting pulled down from the north and cascading over southern Alberta for a few days, producing temperatures we haven't seen the likes of since early June. Sweater weather. A good, warm beverage will be perfect leading toward the weekend. Spice it however you like.
