CALGARY -- Phew! What an alarm clock! The forecast was eyeing some nocturnal thundershowers, then delivered in a big way with the development of this low and a sharp convective blast of northern air that developed between 3 and 4 o’clock, wedging under our warmer overnight air mass and plunging our temperature, while careening us into a loud bout of stormy weather.

This is going to roll steadily across Alberta with an east-northeasterly trajectory toward Drumheller, then onward and away to northern Manitoba. By this afternoon, we should see a few clouds, but enough sun to bring us back to 20 – though that might be our hard-stop moment, as this wave of cool air is going to stick around for a few days.

These are the growing pains of our trough’s arrival. Once it sets in, our primary origin for upper wind will be quite far north of us, which means a few cooler days lie ahead. Tomorrow offers the best chance for instability otherwise, and may bring about another storm, while Sunday looks to stay calm and cool entirely.
