THUNDER BAY – Winter Weather Won’t Let Go! Environment Canada is reporting, “A large low pressure system from Texas is expected to start tracking northeast towards the Great Lakes tonight and Thursday. This weather system will track along a boundary between much milder air more typical of spring to the south, and cold Arctic air which has remained entrenched over Northern Ontario for quite a while now.

Winter Weather staying put?!

Given the forecast track of the low towards the Great Lakes then across Northeastern Ontario Thursday and Friday, quite the contrast in weather conditions is expected across the regions. Northwestern Ontario near and north of Lake Superior.

Snow ahead of this low pressure area is expected to move in by this evening with amounts of 5 to 10 cm expected by Thursday morning and likely another 2 to 5 cm during the day Thursday. The snow may ease off for a while on Thursday before intensifying again by Thursday night as the deepening low moves closer.

It is quite possible that snowfall warnings may be required for later Thursday and Thursday night. For areas from Geraldton eastward across Kapuskasing and north of Timmins, mainly snow and some ice pellets are possible beginning tonight or Thursday. 10 to 15 centimetres of snow are possible by early Friday morning. Additional accumulation is likely on Friday.

For areas near Sault Ste. Marie, mainly rain is expected with this system. Up to 30 millimetres of rain are expected by Friday morning. Travelling conditions especially over western and northern areas where the snow and freezing precipitation are forecast will deteriorate and become hazardous by Thursday. Untreated surfaces may become icy and slippery. For much of Northeastern Ontario, rainfall warnings and freezing rain warnings have now been issued.
