Very mild week in Montreal

What a change in the weather this weekend, from arctic chill on Saturday to spring warmth on Sunday. Temperatures soared from overnight lows early Saturday morning of -12C up to highs of 9C on Sunday afternoon. I even had 12C here on L'Ile Perrot, but I believe it was an anomaly, and  have no idea why, but an early Christmas present is on the way this week. I have ordered a new Davis Vantage Vue weather station, and with a little luck we should have it up and running with accurate data within the week. The Acu-Rite model was good for the price, but the data had become inconsistent. Time to climb up the weather station ladder!

In any event it will be a very mild week. The rain that fell yesterday in just a few hours along the cold front amounted to 8.8 mm at the airport and nearly 11 mm here on L'Ile Perrot. That nearly equaled the amount of rain that fell during the entire month of November. This morning the temperature has cooled to around 1C (33F), with quite a few slick spots on the roads. It will be partly sunny today as a weak ridge of high pressure moves across the area. Another cold front will cross the St. Lawrence Valley on Tuesday with more rain, but very mild temperatures ahead of it. Highs will be near 12C (54F), about 12 degrees above normal for the date. The cold front will bring in much cooler air by Wednesday with temperatures falling slowly back below freezing by Friday. There is the potential for some snow by next weekend. Computer models are also starting to hint at a big pattenr change as we move into the second half of December with much colder air and snow on the way for a large area of eastern North America. As I always say, time will tell.
