One more showery day

We continue to have an upper level low spinning near Quebec City, the same one that was over the Atlantic Ocean last weekend. It will slowly drift south into northern Vermont today and eventually east back out to sea by Thursday. Here in southern Quebec and across eastern Ontario we are looking at one more day of showers. Yesterday afternoon the radar image resembled a popcorn machine with little kernels of instability bubbling up all over the place in the cool and humid air. We can expect the same today with a few very small sunny breaks early in the day followed by scattered to numerous showers and even some small hail. We did have a little hail in the late afternoon here on L'Ile Perrot yesterday.
This will be the last day of showers with a very slow clearing forecast for Thursday and warm sunshine by Friday. The temperature will be 10C today, followed by lows near 1C tonight. Friday and into the weekend we can expect much warmer highs near 16C.

Skiers enjoying the 19 inches of fresh powder at Killington, Vermont on Tuesday.
The big precipitation with this system has been falling across the high peaks of the Green Mountains. The oragraphic lift created by the northwest winds has produced steady and at times heavy snow showers with 19 inches so far at Killington Mountain and 15 inches at Jay Peak. The snow has been a blessing it what was otherwise a poor ski season in Vermont. It has allowed both resorts to open trails and welcome hoards of skiers looking for a final run. This was the biggest snowfall of the season in Killington.
