Major Weather Impacts Discussion for December 12, 2012:
Day 1-3: High pressure over the Ohio River Valley will bring nice conditions to the region and this will extend into the Northeast along with the Plains region. A low pressure area will be moving through the Southeast and Northern Florida bringing showers and thunderstorms to the region. High pressure over the Southwest will slowly give away to another new low pressure system that is making its way down the California coast today. The middle of the period high pressure will be along the East Coast expanding back into the Plains and Southeast. A developing low pressure will be moving into Arizona during this time bringing snow to the mountains and rain to the lower elevations. A low pressure will be moving towards Seattle increasing showers and mountain snows to the region. The period will finish with the low moving out into the Central Plains.
Day 4-7: The period will begin with the low moving into the Great Lakes bringing rain and snow to the region. High pressure will be back over the Plains, while the frontal boundary begins to push on shore over the Northwest. The middle of this period will have a low pushing off the East Coast along with a new developing low over the Southern Plains bringing showers and thunderstorms to the region. High pressure will be over the Southwest as the frontal boundary continues to push moisture into the Pacific Northwest.
Day 8-12: The period will begin with a strong low moving up the East Coast with plenty of rain and snow for the region. High pressure will be over the Great Lakes extending down towards the Gulf Coast. Another low will be developing in the Colorado Rockies and slowly push into the Plains. A weak ridge will set up over the West Coast allowing for a break in moisture. The middle of the period will have some strong winds along with showers and snow showers impacting the Northeast. A frontal boundary will begin to develop along the Gulf Coast, while a very strong 1046mb high begins to push in over the Northern Rockies and Plains section bringing some very cold air to the region. Another frontal boundary will begin to push towards the West Coast. The interaction with the high to the east and the low to the west will put the West Coast into some very strong winds and possible increased fire danger for the Southwest region around LA.
Day 13-15: The period will begin with Lake effect snows looking very possible along with the weak frontal boundary pushing off the East Coast as a very strong high pressure system moves into the Plains and towards the Gulf Coast bringing some very cold air to the region. Low pressure will begin to push on shore over the West Coast. The middle of the period will still have some lake effect snows along the Eastern Lakes while high pressure will be over the Ohio River Valley extending into the Mid-Atlantic. A strong low pressure system will be pushing into the Texas Panhandle bringing showers and thunderstorms to the region. Another area of high pressure will be moving into the Northern Rockies a large area of precipitation will setup from the Colorado Rockies into the Northern Plains and there will be wide swath of snow. Another strong low pressure system will be pushing towards Southern California. The middle of this period we will be dealing with some major snows across the Midwest for places like Chicago and Detroit. Thunderstorms have to potential to become severe along the Gulf Coast. A 1038mb high will be pushing into the Northern Rockies and Plains, while the low begins to push onshore over Southern California.

Ask The Weatherman for December 12:
Question: What are frontal thunderstorms?
Answer: Great Question today comes to us from San Diego CA. Frontal thunderstorms form ahead of cold fronts mostly, but we can further examine them as certain types of thunderstorms such as multi-cell thunderstorms which mean more than one cell together. Another type is the Super-cell thunderstorms, which are the most severe ones and are responsible for the majority of the tornadoes.

Green Energy Weather Report for December 12:
Wave Energy: A low pressure moving across Florida will bring increased wave action to the Eastern Shores of the region.
Solar Energy: High pressure over the Ohio River Valley will bring nice weather to the Mid-Atlantic. The Southern Plains and Northern Plains will also have good solar energy today. The Southwest will also be another good place for solar energy today.
Wind Energy: The southeast behind the low will see stronger winds which will support wind energy. Another spot will be back along the Pacific Northwest ahead of the next frontal boundary.
Hydro-Energy: This morning Florida and parts of the Southeast will be good sources for hydro energy as the showers and thunderstorms move through the region. The Pacific Northwest will see showers and snow showers increase throughout the day which will help bring more hydro energy to the region.
