Big Story Weather – December 3, 2012
Daily weather forecast and wrap-up provided by redOrbit meteorologist Joshua Kelly.
Big Story Weather from December 1-2: A frontal boundary moved through the Northeast and brought a few showers and isolated snow showers to the region. Another powerful front moved through the Pacific Northwest which brought a lot of rain and mountain snows to the region. High pressure influenced the middle part of the country with mild conditions. This past weekend we also saw some very dense fog setup along the Gulf Coast.
Weather Outlook for December 3: High pressure off the Southeast coast will bring partly cloudy skies to the Northeast all the way southward back into the Gulf Coast and Southern Plains. Low pressure moving through north of Minnesota will bring showers to the region and the associated frontal boundary will also bring a chance of showers to the Great Lakes Region and the Mid-Mississippi River Valley. High pressure over the Rockies will bring nice conditions to the region and also look for a frontal boundary to start impacting the West Coast later this evening increasing the chance of showers through the night. Below is the weather for a few select cities.
New York NY: (Partly Cloudy: 57F) | Atlanta GA: (Partly cloudy: 70F) | Sioux Falls SD: (Partly Cloudy: 52F) | Denver CO: (Partly Cloudy: 52F) | Seattle WA: (Partly Cloudy with Evening Showers: 47F)
International Weather Outlook for December 3: Low pressure to the Southeast of Japan will bring showers and mountain snows. Another area of low pressure over the Koreas will bring snow to the region. High pressure over Eastern China will provide for partly cloudy skies. The monsoonal trough will setup over Singapore and extreme Southeast Asia. High pressure over the Middle East will bring mild conditions to the region. Low pressure moving north of Italy will bring showers and mountain snows to the Alps. High pressure over Western Europe will bring partly cloudy skies to the region along with England. A frontal boundary moving across the tip of South America will bring showers to the region. A frontal boundary moving through Eastern Australia will bring showers and thunderstorms to the region, while high pressure will bring partly cloudy skies to the Western portion of the country. Here is the forecast for a few select international cities.

December 3, 2012 Storm Tracker Update:
Atlantic Basin: Low pressure moving through Western Russia will bring showers and snow showers to the region, while another low pressure moving through Eastern Europe will bring showers and snow showers to the region. The extended frontal boundary has another low sitting over Western Africa which will bring showers and thunderstorms to the region. Low pressure over the Northeast Atlantic will slowly move towards England. Another area to the southwest of that currently has winds around 35kts and a pressure of 1006mb and is being watched for the potential of tropical development. Low pressure moving into the Iceland area will bring increased winds and seas to the region. Another strong low pressure system and associated frontal boundary is moving through Central Canada and is bringing showers to the Northern Plains and Great Lakes.
Eastern Pacific: Low pressure is moving towards the West Coast and should begin to impact the region over the next couple of days with heavy rains and strong winds again.
Western Pacific: Typhoon Bopha currently has winds around 115kts and a pressure of 937mb as it is headed right into the Philippines and will impact the region with very heavy rains, damaging winds and storm surge all up and down the Eastern facing shores. A low pressure area is moving southeast of Japan bringing showers to the Tokyo area. Another frontal boundary is over the Koreas and this one is bringing coastal rains along with higher elevation snows.
Indian Ocean: A tropical low is to the South of India and right now has a moderate chance of developing into a tropical system as winds are currently around 25kts and a pressure of 1004mb.
Southern Hemisphere: A low pressure is pushing to the East of the tip of South America bringing with it a few showers to the eastern shores. Another low pressure is moving towards the Southeast coast of Australia and its associated frontal boundary will bring showers back into the region.

Major Weather Impacts Discussion for December 3, 2012:
Day 1-3: High pressure off the Southeast coast will bring nice weather to the Northeast all the way into the Southeast and back into the Gulf Coast region. A low pressure area moving through the Great Lakes region will bring showers to this region. High pressure over the Rockies will bring nice weather which will extend into the Southwest. An approaching frontal boundary along the Pacific Northwest will bring showers back into the region by this evening. The middle of this period will have the frontal boundary pushing through the Gulf Coast and Southeast bringing a few thunderstorms to the region. The end of the period will have the frontal boundary pushing off the East Coast, with high pressure building in behind it and also another frontal boundary moving through the Northern Rockies along with a frontal boundary over the Pacific Northwest.
Day 4-7: The period will begin with high pressure off the East Coast and a frontal boundary moving through the Ohio River Valley back to the Gulf Coast region. Another frontal boundary will be developing over the Central Rockies which could bring a heavy snow band into the Dakotas during this time. Another frontal boundary will begin to push on over the Pacific Northwest. The end of the period will have the frontal boundary pushing along the East Coast along with a high pressure system moving through the Northern Plains along with another low pressure developing in the Northern Rockies which will slowly push eastward.
Day 8-12: The period will start with high pressure over the extreme Northeast US, while a strong low pressure system moves into the Plains. This system could bring one of our heaviest snowfall events of the season to the Dakotas and Minnesota with snowfall amounts in the 4-6 inch range. High pressure will be along the West Coast. The middle of the period will have high pressure over Maine, and the strong frontal system will be pushing into the Ohio River Valley bringing showers on the warm side, along with significant snows on the Northwest side back into the Great Lakes and also strong to severe thunderstorms in the Southeast and Gulf Coast region. High pressure will build in over the Rockies during this time. Another frontal boundary will begin to enter the Pacific Northwest. The middle of this period we will have the center of our powerful storm system over the Great Lakes at 997mb with the warm front pushing into the Northeast bringing heavy rain to the region along with the cold front extending back into the Midwest and Gulf Coast region. Along this boundary we will see rain and some very strong to severe thunderstorms towards the Gulf Coast where another low pressure system will try to develop along the boundary. There will also be snowfall in the Western Great Lakes associated with the frontal boundary. Another significant event is that the developing low over the Gulf Coast will have a very cold air pocket located back over Western Texas which could produce some snowfall in the Amarillo Texas region. The end of the period will have the powerful low pressure move into the Northeast and all the weather will also shift into the region.
Day 13-15: The period will start with the frontal boundary exiting the Northeast along with high pressure over the Gulf Coast region. Another weak clipper system will be moving through the Northern Plains while another low begins to develop over the Northern Rockies. The period will end with the low pressure pushing into the Gulf Coast and then up the East Coast as a possible significant snow storm.

Ask The Weatherman for December 3:
Question: What is a Marine Time Tropical Air Mass?
Answer: This type of air mass is noted for having moisture in it and is found over open ocean waters. It is very common in the tropics region which means it’s warm. By definition it’s a warm and moist air mass. The United States gets impacted most often along the Southeast and Gulf Coast by this type of air mass. It is associated with the Bermuda-Azores High pressure that we see setup in our region every summer bringing warm and muggy mornings and days to the region.

Green Energy Weather Report for December 3:
Wave Energy: The Pacific Northwest will see continued frontal boundaries moving through which will keep the wave energy pretty good for the next few days.
Solar Energy: The Northeast down into the Southeast and back into the Gulf Coast will be an excellent wide area for solar energy today with the high pressure sitting off the Southeast Coast. A second good area of solar energy will develop over the Rockies and Southwest where another area of high pressure will be in control of the weather.
Wind Energy: The Pacific Northwest will see plenty of moderate southwesterly winds ahead of these fronts which will bring plenty of wind energy to the region. A second area behind a cold front moving thorough the Northern Plains will bring some good winds to the region.
Hydro-Energy: The moderate rainfall through the Northwest will bring this region into a great hydro energy area again today. Also look for some rain to move through the Great Lakes region today which will bring some good Hydro-Energy to the region.
