It is a little like September this morning as reality begins to arrive for most of us. The truth is we are on the backside of summer 2013. It is not over by any means but is has been cooler and the nights are getting longer with lots of dew and even some fog around. This morning it was 9.9C here on L'Ile Perrot with lows as cold as 7C in Kemptville, ON and 2C in Saranac Lake, NY. Today will be sunny with temperatures recovering to 22C (72F), a very pleasant, low humidity day. The entire week looks good with temperatures warming to the middle 20's with the best chance for showers coming Thursday.

The skies were wild over the weekend here in southern Quebec as an upper level low traveled across the region. Both days started off dry but the atmosphere quickly became unstable with lots of showers and thunderstorms developing. Clouds were impressive playing hide and seek with the sun producing lots of rainbows. Spectacular lightning lit up the sky Saturday night here on L'Ile Perrot. There was even some hail reported southeast of Montreal.
