September Ends with Strong Regional Temperature Variations; Storms Across Canada and Northern U.S. Tropical Storm Karen Dissipated.
Weekend Review (29-30 September 2007): Cool relief came to much of eastern North America in the form of Canadian high pressure. High temperatures were closer to seasonal readings, generally in the 70s. It was a dry, pleasant weekend across a large area to include the Midwest, Northeast, and Southeast.
Eastern Canada was wet until Sunday. The Plains and Prairies warmed considerably into the 80s with some 90s; scattered showers were widespread ahead of a cold front moving through the Rockies. Another strong cold surge came into the Pacific Northwest and moved swiftly across the western Canada and the Northern Rockies.
High temperatures were unseasonably cold behind the cold front with high temperature readings in the 50s and lower 60s. While widespread rains accompanied this cool invasion, some snow was likely above 3,500 feet. Tropical Storm Karen dissipated in the open Atlantic while Tropical Storm Melissa further east will likely do the same.
Last Week (week-ending 09/29/2007): It was a week of strong weather variations through the week. Early week, the strong cold blast in the West caused temperatures to plummet and provided widespread heavy rains to include California, which experienced an average of 1 to 2 inches of much needed precipitation.
Mountain snows were widespread. The cooler air mass didweaken somewhat, but moved eastward into the Plains by mid-week, sharply dropping temperatures and providing showers and thunderstorms. Ahead of this much cooler air mass, temperatures warmed considerably up and down the East Coast.
