The US storm season has intensified, with Kansas experiencing 100mph winds and tennis ball-sized hail on Sunday.
This year has seen a particularly active severe storm season, as late spring and early summer typically pose the highest risk for tornadoes in the Plains and Midwest.
A low-pressure system moving across the central US, combined with moisture from the Gulf of Mexico, is expected to maintain the threat of tornadoes and large hail across multiple states. This severe weather risk could stretch from Oklahoma to the Great Lakes on Tuesday.
This low-pressure setup might trigger a significant outbreak of severe weather across the US later this week and cause a sharp temperature divide across the US and Canada.
Canada and South America experience extreme temperature shifts as weather systems bring unusual conditions.Warm air moving to higher latitudes will likely result in temperatures reaching 10°C above the seasonal average in eastern Canada and the northeastern US. Cities like Ottawa and Detroit could see daytime highs of 30°C by Wednesday.
Meanwhile, in western Canada and the US, temperatures are expected to drop by nearly 20°C on the other side of the cold front. This drop is due to the same low-pressure system pulling colder air to lower latitudes.
Maximum temperatures may struggle to reach double digits on Wednesday and Thursday before returning closer to the seasonal average.
Similar temperature extremes are expected in South America. Parts of Brazil and Paraguay could experience temperatures 6-8°C above average, while large areas of Chile and Argentina will feel the onset of winter, with temperatures dropping over 10°C below normal.
In Argentina, Mendoza may struggle to reach 5°C on Friday, about 13°C below average, with the cold expected to persist into the weekend.
