Environment Canada has issued a special weather statement for Chatham-Kent, as bitterly cold Arctic air returns Saturday night and Sunday.
After a very cold Friday morning where a few new record low temperatures were set, there will be a temporary reprieve from the very cold temperatures tonight. An Alberta clipper will bring clouds and a few cm of snow tonight into Saturday with temperatures slowly rising to near normal values for this time of the year by Saturday morning.
However a sharp Arctic cold front will blast across Southern Ontario on Saturday, bringing the snow to an end. In its wake, strong and gusty northerly winds will once again usher in fresh Arctic air, with temperatures falling Saturday afternoon and night likely to near minus 20 or below by Sunday morning.
There is a chance wind chills will reach warning levels across the regions Saturday night, and extreme cold warnings may be issued by Saturday as a result.
The lake effect snow machine is also expected to get into gear again Saturday over areas near Lake Huron. Snow squalls will be quite possible from Huron County through Middlesex into Lambton counties again by Saturday night. Dangerous winter driving conditions are quite possible in the snow squalls as a result.
Sunday looks to be a windy and bitterly cold day, with temperatures struggling to get above minus 18 in many areas. Strong and gusty northerly winds combining with the very low temperatures will likely result in extreme wind chills. Sunday into Sunday night may be the coldest day and night of the season so far for many regions.
After what looks to be a frigid start on family day, temperatures should slowly moderate upward as a high pressure ridge finally cuts off the frigid northerly flow.
The public is advised to monitor future forecasts and warnings as warnings may be required or extended.
