Big Story Weather – December 4, 2012
Daily weather forecast and wrap-up provided by redOrbit meteorologist Joshua Kelly.
Big Story Weather from December 3: The high pressure in the Southeast brought nice weather to the East Coast and also into the Gulf Coast region. The frontal boundary that moved through the Northern Plains and also into the Great Lakes brought some colder air with it along with showers and some severe weather. Some places to the West of Chicago actually had Tornado Warnings issued last night in the area. High pressure along the Rockies brought dry weather to the region and the next frontal boundary that moved on shore over the West Coast brought back more rain to the region.
Weather Outlook for December 4: High pressure will begin to push further away from the East Coast this morning allowing for the frontal boundary to start pushing into the area. The frontal boundary will be from the Great Lakes southward into the Southeast and Gulf Coast bringing showers and thunderstorms to the region. High pressure over Colorado will bring partly cloudy skies to the Southern Rockies and also into the Plains for today. The frontal boundary just of the West Coast will bring another day of showers and mountain snows to the Pacific Northwest. Below is the weather for a few select cities.
Boston MA: Partly Cloudy with Evening Showers: 56F
Gulfport MS: Mostly cloudy with Thunderstorms: 75F
Fargo ND: Partly Cloudy: 27F)

High pressure over Northeast China will bring partly cloudy skies to Eastern China and also into the Koreas. Low pressure to the south of India will bring a few showers into the region. Low pressure over Eastern Europe will bring a few showers to the region and also some snow showers to Northern Europe. High pressure to the West of Spain will bring partly cloudy skies to the region. Low pressure to the west of the tip of South America will bring partly cloudy skies and a few showers to the region.

December 4, 2012 Storm Tracker Update:
Atlantic Basin: Low pressure moving through Eastern Europe will bring showers and snow showers to the region. Another low pressure system moving into England and Northwestern Europe will also be responsible for showers and snow showers. A very deep low pressure system is moving through the Northern Atlantic this morning with winds in excess of 50mph along with high seas. A secondary low to the southwest of that is also moving through the area and will begin to push eastward across the Atlantic towards Spain. There is another low over the tropical region of Africa bringing rain to the region along with the Cape Verde Islands. Low pressure moving north of the Great Lakes will bring a frontal boundary down across the Great Lakes, Ohio River Valley and the Gulf Coast today.
Eastern Pacific: Low pressure is moving on shore over the Canadian West Coast and the associated frontal boundary is now bringing showers and mountain snows to the Pacific Northwest today.
Western Pacific: Typhoon Bopha currently has winds around 95kts and a pressure of 952mb as it is now moving through the Philippines and will continue to create large impacts in the region with very heavy rains, damaging winds and storm surge all up and down the Eastern facing shores. Low pressure is moving well east of Japan this morning as this low is headed towards the Western Gulf of Alaska and another low pressure moving through Russia and Northern Japan is bringing snow to the region.
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. Low pressure to the Northwest of Australia will start to impact the region with showers and extensive cloud cover for the Northwest portion of Australia.
Five Day Storm Index Outlook for December 4-8:
Boston MA: Looking for a frontal boundary to move through the region over the next couple of days which will bring slight impacts to the area. On the 8th another frontal boundary will bring slight impacts to the region again.
Gulfport MS: As the frontal boundary moves through the region today expect to see a few strong thunderstorms which will bring moderate impacts to the region. Tomorrow a few showers will still be in the area keeping the region in a slight impact. The rest of the period will remain impact free.
Fargo ND: A very nice start to the period with the chance of seeing a few snow showers by the 8th which will put the region into a slight impact area.
Salt Lake City UT: Nice today and then a frontal boundary tomorrow will bring slight impacts to the region and again on the 8th another frontal boundary will bring slight impacts to the region.
Portland OR: The continued flow of frontal moisture moving into this region will keep it with slight impacts over the next five days.
Climate Watch for November 29-December 3:
Boston MA: The period started with temps around 4-9 below average and then fell to around 14 below average before warming up to around 6-13 degrees above average to finish the period.
Gulfport MS: The temps started around 2 below average and then rose to around 3-8 degrees above average for the remainder of the period.

Major Weather Impacts Discussion for December 4, 2012:
Day 1-3: High pressure of the Mid-Atlantic Coast will bring one more nice day of weather to the region. The frontal boundary over the Great Lakes and Ohio River Valley extending down to the Gulf Coast will bring showers and thunderstorms to these regions today. High pressure over the Colorado Rockies will bring nice weather to the Plains and also the Southwestern US today. The frontal boundary pushing on shore over the Pacific Northwest will keep the region unsettled with heavy rain and mountain snows. The end of this period will have high pressure back over the East Coast and also another developing low coming out of the Rockies which will start to impact the Plains. The Northwest will still be dealing with onshore flow from frontal boundaries.
Day 4-7: The period will start with a frontal boundary pushing out of the Great Lakes and into the Northeast with showers and even some snow possible for places. The frontal boundary will extend back into the Gulf Coast region and Eastern Texas. High pressure will setup over the Northern Plains, while another low pressure develops over Colorado. High pressure will start to slow the weather pattern down along the West Coast finally for the time period. The end of the period will see the low pressure system move into the Gulf Coast region bringing showers and thunderstorms to the region the warm front will extend into the Northeast. A strong area of high pressure will build in over the Northern Plains and the Rockies clearing out the region. A cold front will push through the extreme Northern Part of Washington State.
Day 8-12: The period will start with the low pressure system in the Northeast just off the coast. We could be dealing with some heavy rains and even some moderate snows in the region. The frontal boundary will still extend all the way into the Southeast and Gulf Coast bringing more showers and thunderstorms to the region. High pressure will build in over Texas, while another weak frontal boundary pushes through the Northern Plains. High pressure will prevail over the West Coast. The middle of this period we will see high pressure over the Northeast along with a developing low pressure area in the Western Gulf of Mexico near Texas which will bring plenty of rain to the region again. High pressure will be in control of most of the Western US as a weak frontal boundary approaches the Pacific Northwest.
Day 13-15: The period will start with high pressure pushing off the East Coast, while a frontal boundary is making its way across the Midwest and Gulf Coast along with another frontal boundary moving through the Northern Plains and strong onshore flow over the Pacific Northwest again. The middle of the period will have another low pushing up the Eastern Seaboard bringing the chance of more showers and snow showers to the region. The end of the period will see another strong low pressure system moving into the Great Lakes region with the associated frontal boundary extending into the Gulf Coast region. A strong high pressure system will be in place over the Rockies while another strong low hits the Pacific Northwest.

Ask The Weatherman for December 4:
Question: What is a Continental Tropical Air Mass?
Answer: This type of air mass exists in the United States and can be found in the Southwest portion of the United States. It is classified as having very dry and warm air to it. This type of air mass is very strong in the summer months this is why Arizona gets into the 100’s, but it’s very dry along with that heat.

Green Energy Weather Report for December 4:
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 best places today for solar energy use will be in the Mid-Atlantic region ahead of the next frontal boundary and also back in the Northern Plains along with the Southern Rockies and Southwest portion of the US.
Wind Energy: The Pacific Northwest will again today see moderate winds which will support wind energy and also looking for a couple places on the backside of the front into Missouri and the Western Great Lakes as being wind energy places today.
Hydro-Energy: The frontal boundary out west will keep the Pacific Northwest as a prime place for Hydro Energy today again through the rain and also the long term mountain snows that are building up in the region. The second place will be in the Midwest and the Gulf Coast along the frontal boundary there should be some reasonable rainfall.
