THIS WEEK: FROM THUNDER TO SNOW TO THE CHANGE OF SEASONS

This is the season that is afraid of commitment. It’s hot one day, cold the next. Stormy Wednesday, snowy Thursday.

Widespread rain and wet snow will form over southern Alberta throughout the day Thursday. Rainfall totals will be below what we need to cope with the drought, with 10-20mm on tap with this latest wave of rain, but every little bit is helping to reduce the deficit. A few rumbles of thunder are also possible.

A period of heavy, wet snow will develop in the southern and central Rocky Mountains, with decent accumulations along the foothills of Alberta. It’s hard to get daytime accumulations with the high angle of the sun in mid-May, but any snow that falls overnight or at a decent enough clip will start to accumulate on surfaces and trees.

A snowfall warning is in effect for the 10 to 20 cm expected in high elevations through Friday.

“Be prepared for rapidly changing and deteriorating travel conditions,” Environment and Climate Change Canada (ECCC) says in the snowfall warning. “Visibility can sometimes be suddenly reduced in heavy snow.”

Some wet snowflakes are also possible at lower altitudes towards QE2. Forecasters are watching closely how close the snowpack will get to Calgary and other major population centers in the region. Travel will be impacted in areas that see snowfall accumulation.

Temperatures Thursday are expected to be up to 12°C cooler than normal in southern Alberta. Widespread freezing and rapid freezing are likely for several nights. Temperatures will recover somewhat on Sunday and Monday.
