First snow across Rockies & warm in southern Quebec

Summer 2013 is just about over with the Fall Equinox to occur this Sunday. The summer will end cold out west and with a warming trend here in the east. Montreal can expect sunshine today and Friday with warm high temperatures of 24C and 27C respectively. High pressure that has dominated all week will slowly slide off to the east allowing a cold front to cross the St. Lawrence Valley on Saturday. So sadly it looks like showers for both days this weekend. Temperatures will cool back down into the high teens for both days.

There is lots of weather to speak off across North America from tropical activity in the south to snow in the west and across portions of Alaska. September snow is not unusual, but being that it has been such a warm summer, it is a little surprising. A couple of centimeters fell at Sunshine Village near Banff yesterday as seen on the their webcam image above. It should melt today as temperatures warm up slightly in Alberta.

Mexico continues to be hammered by two tropical systems causing severe flooding with over 60 deaths reported. Hurricane Manual has re-developed just off the Pacific coast and continues to pound the region with heavy rain. Forecasters are now watching the warm Gulf of Mexico waters near the Yucatan for development of the next storm, Jerry. Several computers models develop this storm and take Jerry towards Florida so this system will have to be watched over the next 48 hours.
