Calgary weather: Westerly flow provides respite from wildfire smoke

Calgarians woke up to freshly watered lawns after light rain fell overnight.

Showers will continue across southern Alberta on Tuesday morning and there is a chance of non-severe thunderstorms throughout the day in southeastern Alberta.

A smaller low-pressure system in southern Alberta and Saskatchewan will continue to block smoke from northern Alberta and BC on Tuesday – therefore the Air Quality Health Index (AQHI) for Calgary is expected to remain around 3, or low risk.

Convective activity is possible Tuesday in northern Alberta – an area that is already overly dry and vulnerable to wildfires.

The relative fire danger index – a relative evaluation that rates how easy it would be to start a wildfire, how difficult it would be to extinguish a wildfire and the amount of damage a wildfire could cause – showed very high and extreme reviews in the north and north of the country. central Alberta on Tuesday morning.

Recent rainfall in southern Alberta has left most of that area at low to moderate risk.

Until the start of the long weekend, daytime highs will remain slightly warmer than average. A pattern shift will bring cooler than average temperatures on both sides of the daily cycle Friday through Sunday, with isolated rain possible.
