As far as daytime high temperatures go, Tuesday and Wednesday will be the warmest days of the week, potentially challenging the record highs. We have a decent shot at the record set Tuesday in Montreal, which was 10C (50F) set in 1994. Wednesday and Thursday may be a little more difficult, with the current records dating back to a very warm February in 1981, at 13.9C (56F) and 15C (59F) respectively. The current forecast calls for highs of 8 to 12C (45F to 54F) both days. The overnight lows Monday through Wednesday should remain above freezing as well, near 5C (41F).
A cold front arrives late Wednesday, accompanied by flurries and cooler temperatures.
