Major Weather Impacts Discussion for October 1, 2012:

Day 1-3: Low pressure over the Southeast will lead to a large area of thunderstorms and some severe weather. Also the high pressure moving in over the north will bring colder conditions to the area. The down sloping winds in the West will lead to some dry and very warm conditions in the Los Angeles Basin and surrounding areas.

Day 4-7: Strong area of high pressure will make its way down the Plains towards Texas and bring some very cold air into the region. The frontal boundary will continue to move through the Northeast bringing showers to the region.

Day 8-12: Another low pressure system will move through the Northern Plains and bring with it some colder air and the possibility of snowfall from the Plains into the Great Lakes region.

Day 13-15: A 1044mb high will push in and bring the first taste of Arctic air to the region with many places seeing low temps in the teens. This may just be the start of a very long winter. Also this cold air will push over the warmer surfaces of the south creating rain showers in the south along a boundary.

Ask The Weatherman for October 1:

Question: What is an Alberta Clipper?

Answer: This feature is a low pressure system that develops over the plains of Alberta Canada and moves southeastward towards the Northern Plains and Great Lakes and then exits out the Northeast. The reason behind the Clipper is that it "clips" the United States.
