Daily weather forecast and wrap-up provided by redOrbit meteorologist Joshua Kelly.
Big Story Weather from December 21: A very strong low pressure system brought heavy snow and very strong wind over a large portion of Iowa, Illinois, and Wisconsin. The strong storm brought a foot of snow to Des Moines, Iowa, and as much as 19 inches to Madison, Wisconsin. The storm system produced wind gusts over 50 miles per hour in several areas. In Chicago, heavy snow and strong wind brought white out conditions and some power outages. Yesterday we also saw an area of severe weather develop in the Southern region of the front along the Gulf Coast with well over 40 wind damage reports and a significant tornado that hit Mobile, Alabama.
Weather Outlook for December 21: Low pressure pushing up the East Coast will bring areas of showers to the coast along with moderate snows on the Northwest side as the lake effect snows will kick in over the Eastern side of the lakes for places like Buffalo NY. High pressure will begin to build in over the Southern Plains this will bring with it clearing skies and very cold weather all the way to the Gulf Coast region. Another area of low pressure will be moving into the Northern Rockies; expect to see some snow develop on the back side of this system as well for places like Boise ID. A third area of low pressure will be moving in towards the West Coast and will increase the showers along the coast along with mountain snows. Below is the weather for a few select cities.

Major Weather Impacts Discussion for December 19, 2012:
Day 1-3: The period will start with low pressure along the Northeast which will bring showers and snow showers to the region along with a good portion of the Eastern US seeing very strong winds and this will also create the Lake effect snows for the major snow belt cities today. High pressure over the Plains will bring tranquil weather to the region, while another low enters the Pacific Northwest. The period will end with a new low forming in the Southern Plains along with the onshore flow over the Northwest.
Day 4-7: The period will start with a low moving up the Southeast coast which will bring showers and thunderstorms to the Gulf Coast region. Another stronger low will be forming over the Colorado Rockies which will bring snow and rain. A weak area of high pressure will briefly build in over the West Coast. The middle of the period will have another low along the Gulf Coast with showers and thunderstorms – some will be severe again. A very strong high pressure center will be building in over the Plains and there will be a region of moderate snows that develops over the Northern Plains. Another frontal boundary will start to impact the Northwest. The period will end with another major storm moving up the East Coast along with very cold air building in over the Plains and another low pressure area moving in over the West Coast.
Day 8-12: The period will start with a major storm system in the Northeast as high pressure will be building in over the Plains and a strong low pressure system will be moving through the West Coast. Towards the middle of the period we will see the Northeast still getting impacted by low pressure. The Mid-Atlantic back into the Midwest will be dealing with a cold area of high pressure and low pressure will be moving into the Northern Plains. Also look for another low approaching the West Coast. The period will end with high pressure along the East Coast as another storm system begins to take shape in the Southern Plains and also a potent low pressure slides into Southern California.
Day 13-15: The period starts with high pressure along the East Coast. A Gulf low will begin to start developing and a strong cold high pressure center will slide through the Northern Plains along with another significant low pressure system approaching the Pacific Northwest. The middle of this period we will have another major storm system moving out of the Gulf of Mexico towards the Southeast United States. Expect to see snowfall in the deep south with this storm system along with very cold air behind it and another frontal system out west. The period will end with another storm system moving through the Great Lakes with moderate snows and the frontal boundary bringing with it some severe weather to the Gulf Coast region. Another frontal boundary will be moving into the Pacific Northwest.

Ask The Weatherman for December 21:
Question: Why do tornadoes hit the south during the winter?
Answer: Great Facebook question today! The answer to this is that during the months of November and December the very warm air off the Gulf of Mexico interacts with the cold air from Canada. This interaction of the two air masses creates a very unstable atmosphere forcing the region to experience these tornados which can sometimes be significant and we can even see an outbreak in the region just like yesterday with well over 50 tornado warnings in the Mobile, AL region.
