CALGARY -- As with yesterday, that troughing motion aloft is going to swing in toward us. Today, we'll experience a period of marginal instability, which could result in not only spotty showers, but also periods of isolated storms; they'd be short-lived, a little loud, and pass quickly. Can we start calling them "toddler tantrums?"

Areas west of the city could see some light flurries, which may equate to a full centimetre in areas. Melting temperatures will make short work of it.

The rest of the week is going to ride a wave of west wind aloft. Surface conditions enter a "pressure neutral" zone, largely dominated by weak high pressure areas that won't do much to inhibit showers.

I'll say again and always – isolated showers (even thundershowers) aren't enough. Here, making its triumphant return, the fire ban outlook:
