Heavy fog shrouded highways just outside Winnipeg as well as some streets inside the city on Tuesday.

Drivers were urged to be cautious as visibility was greatly reduced and there were no major collisions reported.

Flights at the James Richardson International Airport in Winnipeg were briefly affected during the peak of the fog in the late morning.

Departures were allowed but arrivals were not.

Once the sun broke through just before 11 a.m., the fog lifted quickly.

Temperatures on Tuesday are expected to climb to 15 C, according to CBC meteorologist John Sauder.

That will be the warmest we get for a while.

Rain is expected to move in Tuesday night and into Wednesday morning and temperatures will start dropping. The daytime highs won't get much warmer than 7 C from Thursday through the weekend.
