Major Weather Impacts Discussion for November 21, 2012:
Day 1-3: High pressure over Arkansas will bring nice weather to the region from the Gulf Coast westward into the Southern Plains and also along the Eastern Seaboard. A strong low pressure system begins to move into the Northern Rockies bringing with it higher elevation snows and also heavier rains to the Rockies and the Pacific Northwest. The middle of this period will have an area of low pressure working up the East Coast and also a frontal boundary moving through the Midwest back into Oklahoma. Another frontal boundary will push on shore over the Pacific Northwest. The end of this period will have an area of low pressure moving into the Great Lakes and Northeast a very strong high pressure moving in over the Northern Plains and then the frontal boundary over the Pacific Northwest.
Day 4-7: The period will start with stronger winds in the Northeast with the low just to the north of Maine and also strong high pressure over the Southeast, and a weak frontal boundary moving through the Northern Plains. An area of high pressure will build in over the West Coast allowing for a break from all the moisture in that region. The middle of this period will have strong winds over the Northeast again from gradient winds along with high pressure over the southeast and a developing low pressure over Texas and Oklahoma. The low pressure will be producing snow back over the Eastern Rockies. High pressure will still be in control of the weather over the West Coast. The period will come to an end with the high pressure pushing off the East Coast and a low pressure beginning to push into the Gulf Coast region bringing showers and thunderstorms. Strong high pressure will quickly build in behind this low allowing for some very cold air to settle in over the Southern Plains. Another warm front begins to push into the Pacific Northwest.
Day 8-12: This period will begin with a 965mb low over the East Coast which will have plenty of coastal rains and very heavy mountain snows which may work their way into the bigger cities towards the end. Strong area of high pressure will be settled in over Texas bringing some very cold air to the region. Another frontal boundary will begin pushing on shore over the Pacific Northwest. The middle of this period will have our strong low pressure continuing to work up the East Coast bringing very strong winds, storm surge and heavy rains and even heavy snow to some places. The strong area of high pressure will be over Mississippi during this time period. Another strong low pressure will be sitting just of the West Coast bringing showers to the Pacific Northwest.
Day 13-15:The period will start with the low pressure finally moving out of the Northeast as high pressure shifts into the area which will bring some very cold air to the region this high will also bring cold air to the Gulf Coast and Southeast during this time. The high pressure will bring fair and warmer conditions to the Northern Plains as the southerly flow sets back up. The strong low pressure system over the Pacific Northwest will move on shore bringing increased rains and winds to the region. The middle of this period will have high pressure on both coasts along with a frontal boundary moving through the Plains region. The end of the period will have high pressure along the east coast with a strong low pressure system moving through the Plains and Great Lakes which will bring heavy rains, thunderstorms and even snow to some places. Also look for a possible Gulf Low to start taking shape towards the end of the period.

Ask The Weatherman for November 21:
Question: Why do storms get so strong when they get of the Carolina coast?
Answer: This is another weather area that we have to constantly watch for. When low pressures move across the region they will hit the warm Gulf Stream and explode into big storm systems such as Sandy and also the more common winter storms that impact the Northeast. This warm water just fuels the storm allowing for it to get strong really fast.
