The weather just went from fall to winter in a hurry in Saskatchewan. Winter storm and wind warnings continued Sunday afternoon for the eastern half of the province.Environment Canada meteorologist Dan Fulton called it a “nasty day.” “For Regina and the Qu’Appelle Valley–like Estevan, Weyburn, areas like that–(there are) pretty much near whiteout conditions. Lots of highways closures, snow, blowing snow,” said Fulton.”You’re not going to have too much improvement throughout the day.
