Weekend Update

We are running out of time in securing a white Christmas here in southern Quebec and Ontario. Yesterday was remarkably warm for December, or even November, with temperatures soaring to 11C in Montreal and we already have recorded a high of 10C today, it came during the overnight hours. The temperature has been dropping since, and now sits at 4C. They will bottom out at a cold -10C overnight tonight. Showers accompanied the cold front this morning and a secondary shot of cold air by the middle part of the day could produce flurries. Heavy rain occurred over Montreal yesterday with 42.5mm at the airport. I measured close to 30mm here on Ile Perrot, but I was having trouble with my computer so that measurement is not reliable. I have since fixed the problem and we are back on track.

High pressure will dominate the weather for the weekend with sunny skies, cool days around -5C and cold nights around -10C throughout the area. The next chance for precipitation will come from a frontal system on Monday that could give us some light snow or once again showers as temperature warm to above normal. We are still watching the weather map for a potential significant snowfall during the middle to late portion of next week, but it is way too soon to pinpoint that forecast.
