3 Day Outbreak

This evening major storms have begun in southern Alberta and will continue to crawl across the prairies over the next 3 days. Southern Alberta tonight, Alberta and western Saskatchewan on Tuesday and most of southern Saskatchewan will see serious severe weather on Wednesday. Forecast models suggest this could be a significant event on Wednesday especially as temperatures rise and the system moves towards the wet zones of Saskatchewan. Many grid roads and most farm fields are now flooded in areas of central and north central Saskatchewan. The heat in the south west will mix with these conditions and likely fire up some very big storms this week.

Severe Weather Outlook For Tonight

Severe thunderstorms will track north and east this evening and overnight with nocturnal storms lasting until morning where they will begin further east into Manitoba. These are supercell thunderstorms so please take all warnings from Environment Canada very seriously. There is not likely to be major damage caused but localised flooding and large hail, strong but brief tornadoes can not be ruled out. STAY SAFE!

Supercells Tonight In South West Saskatchewan #skstorm

After many excited reports of heavy rain in central Alberta that even resulted in tornado warnings being issued, some very real storms are starting to make their way as forecast into south west Saskatchewan. With echo tops of over 40k feet compared with the 25k foot storms earlier today around Edmonton, there is a very serious risk of damaging winds of up to 100km/hr and hail of golf ball size or 1 inch. Two supercells, one currently over Leader, Saskatchewan and the other much bigger complex of supercells is just south of the US border in Montana about to enter extreme south west areas of Saskatchewan. People need to take immediate safety precautions in the areas warned by Environment Canada and STAY SAFE!

Severe Weather Today In Alberta - 11am Risk Map

Severe weather is expected this afternoon in areas of Alberta and south west Saskatchewan. The largest most powerful storms will be in the southern sector producing damaging winds and large hail. Also of note today, the SPC in the USA has issued a very rare "High Risk" day around the city of Chicago.

Severe Weather Outlook This Week [NEW MAP]

The next three days will be very active with severe thunderstorms starting from southern Alberta into Montana with a much bigger system in the Ohio Valley towards southern Ontario. Already a Moderate Risk has been issued for tomorrow by the Storm Prediction Center in Norman, Oklahoma covering areas of the states of Illinois, Indiana and Ohio.  A Slight Risk for southern Alberta, south west Saskatchewan and most of the state of Montana will mean serious storms with supercells and damaging tornadoes likely. Things will progress east each day with most activity staying close to the US border... likely very big storms, but nothing like we saw in Oklahoma a few weeks ago during those major historic outbreaks. The threat for danger increases though, especially Thursday in south west Saskatchewan with very hot winds aloft pushing in from Montana. To pin point areas of most danger here on the Canadian Prairies, Wednesday will be mostly between Lethbridge and Medicine Hat towards Cypress Hills, Thursday will be from Kindersley to Maple Creek and over to Assiniboia, Friday things will get going from Yorkton to Brandon in the east but still that is a few days away so conditions may shift either way. The way most storms have developed this spring suggests that south west Saskatchewan and south east Saskatchewan will get the most activity. The city of Regina has missed most every thunderstorm so far and that trend will continue until we get closer to July. So far this season, Saskatchewan has had two confirmed F-0 tornadoes and no damage reported as yet.

Please watch for public watches and warnings via local media, Environment Canada or The Weather Network, and...
