A record high temperature for Peterborough was set on Monday after a Colorado low pressure system brought a mild southerly flow across southern Ontario.

But the mild spell was short lived as Environment Canada issued a winter weather travel advisory warning of expected adverse travel conditions in the Peterborough area on Wednesday.

"Ice pellets are expected to begin over the area late Wednesday morning," states the weather advisory issued at 3:19 p.m. Tuesday for Peterborough, Lakefield, Lindsay, southern Peterborough County and southern City of Kawartha Lakes.

"A risk of freezing rain or freezing drizzle will accompany the ice pellets. Ice pellet accumulations of 2 to 4 cm are expected before the precipitation comes to an end Wednesday evening or overnight.

"The Wednesday evening commute is likely be affected due to accumulating ice pellets and the potential for untreated surfaces to become icy."

The winter travel advisory is also in effect for areas including Toronto, Kingston, Kitchener and Durham, York and Peel Regions.

Peterborough's high temperature of 10.3 C on Monday topped the modern Peterborough high temperature record of 9 C that was set in 1991, Environment Canada reported Tuesday.

Daily record high temperatures were also recorded at Trenton, Pearson International Airport in Toronto, Hamilton Airport, Kitchener, London and St. Catharines, where the high reached 15.1, breaking the previous record of 13 C also set in 1991, according to Environment Canada.

Because of the meltoff from the mild spell, the Otonabee Region Conservation Authority issued a water safety statement on Monday advising of the potential for high flows and unsafe banks in the Otonabee River and Kawartha Lakes watershed.

As of 4:30 p.m. Tuesday, Otonabee-South Monagah Township closed Baseline Road between McGregor Bay Road and Drummond Line because the road became impassable.

Icy collisions on the roads Monday led to several collisions. Monday recycling in Peterborough County was postponed on some roads in North Kawartha Township and Douro-Dummer Township.

Peterborough County advised motorists to slow down and drive with caution because of the potential for potholes.

"Potholes are naturally occurring and can happen at any time - seemingly overnight, and are particularly common with fluctuating temperatures," county officials said on social media.

Motorists reported water spilling onto roads in a few areas Tuesday morning, including on County Road 4 east of Highway 28 and on Janetville Road north of Highway 7A.

The normal temperatures for this time of year in Peterborough are a high of -3 C and a low of -14 C.

Temperatures gradually dropped all day Tuesday back to seasonably normal levels and some frigid nights are ahead, with a low of -20 C forecast for Friday night.
