Big Story Weather – November 30, 2012
Daily weather forecast and wrap-up provided by redOrbit meteorologist Joshua Kelly.
Big Story Weather from November 29: High pressure along the East Coast kept a majority of the United States under partly cloudy skies and moderate temperatures. However the warm front pushed into the Northern Plains and brought some snow showers to North Dakota. Also the center of the low pushed into the Western Rockies and brought a warm rain to this region. The cold front extended over the West Coast and brought some very heavy rainfall and significant mountains snows.
Weather Outlook for November 30: High pressure near the Northeast will bring nice weather to the region. A weak and dry frontal boundary will push through the Midwest today; only a few showers around Chicago will be possible with this front. High pressure over the Southwest will make for nice weather in the region and this will extend into the Southern Rockies and Southern Plains. Another low pressure system will push across the Rockies and the Pacific Northwest today bringing more showers and mountain snows to the region. Below is the weather for a few select cities.
Pittsburgh PA: (Mostly Cloudy: 50F) | Dallas TX: (Partly cloudy: 70F) | Rapid City SD: (Partly Cloudy: 55F) | Topeka KS: (Partly Cloudy: 61F) | San Diego CA: (Partly Cloudy: 66F)
International Weather Outlook for November 30: High pressure moving into the Koreas will bring partly cloudy skies to the region and this will also extend eastward into Japan. High pressure over the Tibetan Plateau will bring partly cloudy skies to the region and will also decrease the monsoonal trough over Southeast Asia. High pressure over the Middle East will bring dry weather to the region. Low pressure over France and Germany will bring showers and higher elevation snows. Low pressure near England will also bring scattered showers. Low pressure to the west of the South America tip will bring increased clouds to the region. High pressure over the Northwest of Australia will bring partly cloudy skies to the region, while a frontal boundary will be moving south of the region bringing scattered clouds and showers to the southern part of Australia. Here is the forecast for a few select international cities.

Major Weather Impacts Discussion for November 29, 2012:
Day 1-3: High pressure moving into the Northeast will bring nice conditions to the region. The southeast and Gulf Coast will also enjoy nice weather today on the backside of the high. Look for a weak frontal boundary to move through the Great Lakes region bringing some showers to the region. High pressure over the Southwest will bring nice conditions to the region and another frontal boundary moving on shore over the West Coast will keep the region unsettled with showers and mountain snows. The period will finish with a frontal boundary extending through the Northeast bringing showers to the region and also another frontal boundary moving through the Northern Plains. A weak frontal boundary will also be extending through the Pacific Northwest with a few showers in the region.
Day 4-7: The period will start with high pressure along the East Coast and a frontal boundary moving through the Great Lakes with the associated frontal boundary extending into the Gulf Coast region. High pressure will be over the Rockies along with another Low pressure system pushing in over the West Coast bringing more showers to the region. The middle of this period will have the frontal boundary along the East Coast with high pressure building in over the Plains and Midwest along with High pressure over the Southwest and another frontal boundary along the Pacific Northwest. The end of this period will have high pressure building in over the East Coast again along with a frontal boundary building over Southwest Colorado and a weak high pressure center along the West Coast.
Day 8-12: The period will start with high pressure along the East Coast and another frontal boundary extending from the Great Lakes into the Gulf Coast region bringing the area showers and even snow on the northwest side and some strong thunderstorms to the Gulf Coast region. A weak frontal boundary will move into the Pacific Northwest. The middle of the period will start with high pressure pushing off the East Coast and a warm front pushing into the region bringing showers to the Mid-Atlantic region. Along with that look for a 1000mb low over the Rockies which will impact the Eastern United States with showers and thunderstorms along with a moderate snow band to the Northern Plains. The end of this period we will have a significant low pressure system over the Great Lakes and this will have some severe weather along the southern boundary and showers on the Eastern Boundary and a significant snow event back over the Northern Plains and into the Western Great Lakes.
Day 13-15: The frontal boundary will move into the Northeast with plenty of moisture being available with showers along the I-95 larger cities and to the west expect to see some snow that might be heavy over some regions in the Western part of the Northeast. The frontal boundary will extend into the Gulf Coast bringing some moderate rains and possible severe weather to the region. A 1038mb high will build in over the Northern Plains. The period will end with another low pressure system coming out of Eastern Texas that will push up towards the East Coast as it crosses the Gulf Coast region.

Ask The Weatherman for November 30:
Question: What is an Air Mass?
Answer: The best way to describe this is you first need to understand that an air mass forms in what is known as a very flat and uniform terrain such as the Ocean or the Canadian Flat lands. Secondly an air mass is made of uniform temperatures such as the following types: Frigid/ Cold /Warm. The next feature is an air mass is made up of moisture or dry air. As an example, if the air mass forms over water it is considered moist, and if it forms over land it is dry. More to follow on air masses later in another question.

Wave Energy: The frontal boundary moving across the Pacific Northwest will bring some moderate waves to the region.
Solar Energy: The best solar energy today will be found in the Northeast where high pressure will bring nice conditions and also back into the Southeast on the backside of the high pressure and the Southwest will be under high pressure making that region enjoy some great solar energy today.
Wind Energy: The storm system in the Pacific northwest will again bring some moderate winds to the region and also this will spread out into the Northern Rockies today. These areas will be supportive of great wind energy. A small area of moderate winds will also develop over the Dakotas today behind a weak cold front.
Hydro-Energy: The Pacific Northwest again today will see moderate amounts of rain and snows that will create great hydro energy producing conditions for the area. A small area of showers will develop along the Chicago area also today which could bring some hydro energy to the region.
