Niagara to remain under freezing rain warning for the weekend

Niagara remains under a freezing rain warning. 

The weather office says an ice storm likely this weekend. 

A low pressure system is slowly tracking towards the lower Great Lakes, as it gets closer, brisk northeasterly winds will pump in cold arctic air, forcing temperatures to fall to near or below the zero degree mark on Saturday.

Rain associated with this low will change to freezing rain on Saturday morning and will likely persist for a number of hours into Saturday night. Freezing rain may become mixed with or turn over to ice pellets at times Saturday.

Freezing rain may taper off to patchy freezing drizzle for a few hours Saturday night.

However, as the low gets close to Southern Ontario Saturday night, freezing rain is expected to move back in, and may persist well into Sunday before changing to rain that could be heavy at times.

Some uncertainty exists as to the time the precipitation switches to rain on Sunday. Enough rain may fall later Sunday into Sunday night for some flooding to be an issue to deal with then.

Some areas inland from Lake Ontario may receive more than 20 mm of freezing rain, which would result in higher amounts of ice accretion especially if temperatures hover a couple degrees below zero.

Ice accumulations of this magnitude combined with gusty northeast winds to 60 km/h may result in widespread power outages due to fallen tree limbs and power lines.

Dangerous winter driving conditions are expected on untreated roads Saturday and Sunday.

Surfaces such as highways, roads, walkways and parking lots may become icy and slippery.

Slow down driving in slippery conditions. Watch for taillights ahead and maintain a safe following distance. Ice build-up may cause tree branches to break. Utility outages may occur. 

Utility companies have issued warnings and are prepared for emergencies.

Brock University cancelled all exams for tomorrow.  

Saturday exams have been rescheduled to Thursday April 26th.
