Environment and Climate Change Canada has issued a stark warning for Calgary and surrounding regions, forecasting a dramatic return to winter conditions this week. Meteorologist Janelle Gergely emphasized that central and southern Alberta are poised for a significant shift, with snowfall expected to begin Monday evening and continue through Tuesday.
Snowfall Predictions and Regional Variations
Snowfall amounts will vary considerably across different areas, but many locations could accumulate between 10 to 20 centimetres by Wednesday morning. Calgary itself is anticipated to receive between five to 15 centimetres, placing it on the fringe of the heaviest snowfall zones.
Eastern Corridor to Bear the Brunt
The eastern corridor, particularly areas east of Edmonton towards Lloydminster, may experience the most severe conditions. Gergely noted that up to 30 centimetres is possible in these regions, with Stettler and surrounding areas likely to see snowfall in the 15-to-30 centimetre range.
Additional Weather Hazards
Beyond snowfall, strengthening winds on Tuesday will lead to blowing snow and significantly reduced visibility. This combination is expected to create deteriorating road and travel conditions across southwestern and south-central Alberta. Temperatures are also set to drop sharply Monday evening, marking a stark contrast to the mild weather experienced earlier in the month.
Long-Term Forecast and Climate Context
Gergely explained that while Calgarians are accustomed to warmer winter periods due to chinooks, the current warm-up has been longer than usual. The incoming cold air is originating from the Arctic, and models suggest it will persist for the foreseeable future. Although the snowfall is primarily a Tuesday event with clearing expected by Wednesday, the cold temperatures are likely to remain, with potential fluctuations between warm-ups and below-normal conditions.
Official Warnings and Preparedness
A special weather statement is currently in effect for Calgary and most of Alberta, serving as an initial alert for the impending change. Gergely advised residents to stay vigilant, as further alerts may be issued in the next 24 hours as confidence in specific snowfall and blowing snow impacts increases. This proactive communication aims to ensure public safety and preparedness for the challenging conditions ahead.
