Warmer weather

After our first taste of frost and fall like weather, we will see a return to mild temperatures this week along with some cloud cover and showers. The weekend was spectacular but chilly with overnight lows in the single digits in most areas and even below freezing across the Adirondacks and Laurentians. Scattered frost was observed at many locations away from the water and urban areas. The high pressure that was responsible for the clear skies and cool temperatures, crested over the region last night and will drift off to the east today allowing for some warmer air to return. Temperatures will rebound after another cool start today up to 21C in Montreal and perhaps 18 to 20C across the region. A cold front will introduce clouds and showers from the St. Lawrence Valley south and east after midnight tonight until midday Tuesday before skies clear out once again. A sunny, warm Wednesday is on tap, perhaps the last 25C day of summer 2011.

Earthquake: A small quake rattled the area yesterday afternoon around 3:19pm. The 4.0 magnitude quake was centered near Buckingham 41km east of Ottawa and northwest of Montreal, and was felt all over a wide area. No damage was reported.
