Frost Advisory for Southern Quebec - NY & Vermont

Our average frost in Montreal typically does not happen until the first week of October on average. But here we are, the last week of summer 2014, and is it not fitting that we have a frost advisory in effect. The entire region is under the advisory with the exception of metro Montreal near the St. Lawrence River and the Richelieu River Valley. A cold front has slipped south of Montreal early this morning. The front produced between 4 and 5mm of rain overnight and now a stiff northerly wind will develop along with steady or slowly falling temperatures. The high here on L'Ile Perrot was 13C (55F) at midnight and we have been falling since. It is currently a chilly 9C (49F). Look for partly sunny skies today and clear skies tonight. Temperatures will fall tonight to around 0C (32F) in most regions of southern Quebec but as cold as -2 to -4C in the Townships and Laurentians. The same cold conditions can be expected in Eastern Ontario and northern New York and Vermont. Freeze and frost advisories/warnings are in effect in those areas as well. We will see sunshine on Friday with temperatures a little warmer, near 13C (55F). Low pressure will affect Montreal over the weekend with showers developing Saturday and lasting into Sunday. It will be much milder with temperatures near 20C (68F) both days.
