Major Weather Impacts Discussion for December 13, 2012:
Day 1-3: High pressure moving through the Southern Plains will bring nice weather to the region and this will expand eastward into the Ohio river Valley and also northward into the Northeast. A frontal boundary extending across Southern Florida will bring showers and thunderstorms to the region. A frontal boundary moving through the Rockies will bring rain and snow to the region, while the Pacific Northwest has one nice day today. During the middle of the period our low pressure will move into the Central Plains bringing with it showers and higher elevation snows. The period will end with the low pressure moving into the Great Lakes and with limited moisture should create some snow in the region and a weak frontal boundary will extend to the Gulf Coast.
Day 4-7: The period will start with the low moving into the Eastern Great Lakes bringing snow and rain to the region. It will gain more strength along the Gulf Coast creating heavy rain and thunderstorms. High pressure will be over the Southwest as another frontal boundary moves into the Pacific Northwest. The period will end with high pressure along the East Coast and the frontal system will move into the Northern Plains bringing precipitation to the region.
Day 8-12: High pressure will push off the East Coast allowing for a strong frontal system to move into the Great Lakes and bring the chance for some moderate snows. The frontal boundary will extend back into the Gulf Coast with showers and thunderstorms. A strong high pressure area will start to ridge into the Northern Plains. Another frontal boundary will begin to push on shore over the West Coast. The middle of the period we will see a large area of high pressure over the Northern Plains bringing some very cold air into the region. There will also be a large area of low pressure sitting off the West Coast pushing small pulses into the area during this time. The period will end with a few showers and snow showers in the Northeast along with the strong high pressure still in the Northern Plains bringing very cold air to the region. A low pressure area will begin to develop in the Southwest Gulf of Mexico and another storm system will be impacting the Northwest.
Day 13-15: The period will start with the potential of lake effect snow of the Eastern Lakes as the high pressure continues to dominate the majority of the country with strong cold air in place. Another frontal boundary will be pushing on shore in the west. The middle of the period will have the strong high finally pushed into the East Coast, while a low pressure system moves into the Plains and another frontal system will push on shore over the Northwest.

Ask The Weatherman for December 13:
Question: What makes a Nor’Easter?
Answer: A Nor’Easter is a special storm in that what makes it up is a low pressure system comes out of the Gulf of Mexico and works its way up the coast. The winter time is more supportive of this pattern and the tricky thing about these types of storms is to forecast the accurate path. The reason this is hard is this could be the difference in a Heavy Snow storm or a Rain storm. If this low tracks west of the I-95 interstate then the large cities get heavy rain. However, if this low tracks to the East of the large cities then they get heavy snowfall. The storm itself can have very strong winds and even create its own storm surge.
