Rain overnight as Calgary kicks off another warm week

Light rain fell across portions of southern Alberta early Monday, including the City of Calgary.

Most surfaces were just wet, but some areas including sidewalks, parking lots, and less-traveled roadways were icy.

Monday will bring another day of stronger westerly winds as well as sunshine, so more melting will occur. Many of those surfaces that start the day with a thin layer of ice will have it melt during the day before potentially freezing again overnight.

There is a chance that a similar scenario will occur early Tuesday morning with a narrow band of rain developing across southern Alberta.

In some communities under an atmospheric temperature profile with cooler pockets, that rain could transition into freezing rain or snow.

The main weather maker right now is an organized upper pattern is enhancing the flow of warm Pacific air into the western provinces, creating chinook conditions across southern Alberta including strong westerly winds.

In Calgary, sustained winds will hover around 20 km/h with gusts of up to 40 km/h. Typical of these setups, winds will be even stronger in southwestern Alberta.

This trend of above seasonal temperatures will continue throughout the week producing daytime highs as warm as 13 C with lows mostly around the freezing mark.

The normal range of temperatures this time of year is 1 C for a high and -10 C for a low.
