Southern Alberta has finally received some beneficial rain over the last couple of days, helping to alleviate a part of the drought that has been a problem for months. There has also been multiple days of thunderstorms, which produced localized flooding, hail and even funnel clouds on Monday. Similar conditions are expected on Tuesday, though with a lesser risk as the system responsible for the setup begins to pull away. More on what occurred Monday and what's ahead for Tuesday, below.
TUESDAY: MUCH-NEEDED RAIN WITH STORM AND FUNNEL CLOUD THREAT LINGERS
After heavy rain and slow-moving thunderstorms produced some localized flooding and hail over southern Alberta on Monday, along with a handful of funnel cloud sightings, similar conditions are forecast once again on Tuesday.

Showers and thunderstorms will continue Monday evening, with rain continuing overnight. On Tuesday, showers are possible with a few rumbles of thunder, as well, but not as widespread as Monday since the system is moving away.
An area of convergence in the atmosphere focused in the southeastern portions of the province could also bring the potential for funnel cloud development at times throughout the day.
In all, between 50-75+ mm of rain is possible in locally stronger storms that remain in an area for an extended period of time.
Calgary receives about 94 mm of rain in a typical June. With 30-50 mm of additional rainfall in the forecast for parts of the Calgary metro area, we’re looking at more than half a month’s worth of rain falling in these couple of days.
Precipitation on the Prairies has been an all-or-nothing story for the past couple of months. While folks over in Manitoba can’t catch a break from the persistent flooding, it’s been tough to come by much rain across the west recently.
Much of southern Alberta has seen less than half of its normal rainfall over the past 90 days. This upcoming round of steady rainfall will help wet the soils and begin to reverse some of the damage this prolonged dry spell has caused.
The dryness has led to an increased fire danger for much of the region. Stay alert for potential evacuation notices if you’re in southern Alberta or southern Saskatchewan. Officials ordered an evacuation on Friday due to a wildfire burning north of Crimson Lake in Clearwater County.
Drier conditions will move in and persist through the end of the week, as temperatures rebound back to seasonal and above by week's end.
A brief period of very warm to hot weather is expected this weekend with temperatures in the mid to upper 20s, and a few spots reach 30°C for southern Alberta and southwestern Saskatchewan on Saturday.
