Drivers on Sunday may have had to content with slippery roads after bouts of freezing rain fell over southern Ontario.

Conditions have changed in a hurry, though, as a warm front sweeps across the province, ushering in mild temperatures.

Any snow or ice accumulation and accretion from Sunday will quickly melt as temperatures rise well above freezing on Monday and rain falls over the province.

The chance for rain will increase as a cold front quickly chases the warm front through the afternoon hours.

Rain will start in the southwestern portion of the province late Monday morning, reaching the Greater Toronto Area by the late afternoon and eastern Ontario by nighttime.

The rain will end as quickly as it appeared, however, ending in the southwest by the late afternoon and ending everywhere else overnight.

Monday has the potential to be breezy, but we won’t see the winds really pick up until the overnight and into Tuesday. Even then, gusts are forecast to only reach 40-60 km/h.

Temperatures will soar to 6-8 degrees above normal on Monday, with folks in southwestern Ontario seeing up to double-digit highs.

The average temperature across southern Ontario for mid-December is 0-1 degree, so Monday will be a significant departure from average.

A stronger cold front is expected to approach the region late next week or during the weekend.

A noteworthy system over the eastern U.S. could be associated with the transition to a few days of much colder weather, but it is much too early to know how or even if this messy system will impact the region.

After a few days of cold weather, temperatures are expected to trend milder as we head into Christmas. At this point, it looks like the final week of December will be mild, but we are watching the potential for a more extended period of consistently cold weather for the first half of January.
