Nocturnal thundershower risk Monday evening for Calgary

AFTERNOON UPDATE: There are few changes from this morning's edition, but with the low crossing out, we'll experience a few shifts; for one, a weak rise along the southern foothills may drive storms from Highway 22 across Highway 2, including Calgary; these are mostly probable past midnight, preceded by the heaviest periods of showers approaching midnight, still.
Rainfall totals and temperatures require little in the way of adjustment. Calgary still faces at least 10 millimetres of rain tonight.
MORNING EDITION: After a rather gloomy weekend, which followed a rather rainy Canada Day (see tweet below for that scoop), we're going to keep the ball rolling into a drab Monday.
The centre of the day's activity is south of us, pulling in Pacific moisture and winding it around the foothills. This will generate upslope flow in some mountain parks, where over 25 millimetres of rain will be possible.
Locally, we will see 15 to 20 millimetres by tomorrow morning, with a chance we go above that marker, especially if isolated storms associated with the system pass by. The majority of this rain falls late this evening, with reasonably consistent periods of showers leading up to that.
Tomorrow afternoon presents another opportunity for thundershowers in the wake of the low moving on into a period of warming for the afternoon – rainfall totals will be light to moderate, pending storms.
We'll rinse and repeat through the week, as well – warmth, with late day potential for rumblings.
