Tornado Risk Today: East Central Alberta

Conditions have increased the threat of very severe weather today, especially in east central Alberta where a risk of strong tornadoes exists. Storms will generally be larger, more powerful than yesterday due to the increase in temperatures and moisture. Storm motion will be very slow once again this evening as cells will be near stationary as the system creeps slightly east from the action last night. Tomorrow the shift will be much greater as it moves into parts of Saskatchewan. A full fledged moderate risk could be issued along the Saskatchewan/Montana border tomorrow as conditions gain even more energy. The main cliff hanger will be Wednesday evening as temperatures drop with the passing storms in southern Saskatchewan but then increases dramatically again Friday night in southern Manitoba. In fact, there is no foreseeable end to this pattern so storm season on the Canadian Prairies is now fully under way and will continue full strength until the end of the current cycle beginning of July.

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!
