Much cooler weather to end the week in southern Quebec

Possible Frost Thursday night for Townships & Laurentians
A cold front southeast of Hudson Bay this morning will race into southern Quebec by this evening. In advance of the front sunshine will allow temperatures to climb to 21C (70F) today. Showers along the front this evening will end overnight from Montreal to the US border and early Thursday across New England. Temperatures will settle back into the low teens tonight and stay there on Thursday as some of the coolest air since last May settles into the region. Temperatures on Thursday will struggle to make it to 16C (60F) in Montreal. Overnight lows Thursday night will be around 6 or 7C in Montreal but as cold as 2 or 3C away from the city and below freezing in the colder sheltered valley's of the Townships into upstate New York and Vermont. This will certainly inject some color into the leaves which are starting to turn here on L'Ile Perrot. The good news is it will be sunny through Friday with just a chance of some showers late Saturday. Temperatures will start to warm again into the weekend as high pressure moves off the east coast.
