Big Story Weather – December 7, 2012
Daily weather forecast and wrap-up provided by redOrbit meteorologist Joshua Kelly.
Big Story Weather from December 6: A frontal boundary that was moving through the Great Lakes and Northern Plains brought some light snowfall to these regions. Also the Pacific Northwest was dealing with more rain and mountain snows as conditions continue to be very saturated in the region. Flooding is now becoming a big concern for the area. The remainder of the East Coast into the Gulf Coast saw a very nice day yesterday.
Weather Outlook for December 7: A cold front is pushing off the East Coast this morning bringing showers and snow showers to the Northeast and a few stronger showers to the Carolinas. Look for most of this to come to an end after sunset. Another low pressure is moving through the Northern Plains bringing with it some of the first bigger snows of the season with some places getting 2-4 inches or close to 6 inches of snowfall in the Dakotas. High pressure will settle in over Rockies bringing partly cloudy skies to the Southern Rockies and Southwest, while cold air behind the cold front will bring a few snow showers to the Northern Rockies. Also another frontal boundary will slowly make its way into the West Coast bringing more showers to the Pacific Northwest. Below is the weather for a few select cities.
New York NY: Mostly Cloudy with Showers: 43F
Mobile AL: Partly Cloudy: 70F
Watertown SD: Mostly Cloudy with Snow Showers: 30F
Denver CO: Partly Cloudy: 50F
Seattle WA: Mostly Cloudy with Showers: 45F
International Weather Outlook for December 7: Low pressure over Northern Japan will bring a few snow showers to the north, otherwise look for high pressure from Eastern China to bring partly cloudy skies to the remainder of Japan and also the Koreas today. High pressure over the Tibetan Plateau will bring partly cloudy skies to the region. High pressure over Eastern Europe will bring partly cloudy skies. Low pressure will move into Norway today bringing a few snow showers. High pressure will begin to move in towards Spain bringing partly cloudy skies to the region and this will extend northward into England. Low pressure will move across the tip of South America bringing a few showers to the region.

December 7, 2012 Storm Tracker Update:
Atlantic Basin: Low pressure out over the Eastern Atlantic will slowly drift towards Europe this weekend bringing showers to the region. Another area of low pressure moving towards Greenland will increase winds and seas. A third low pressure system moving off the coast of Florida will move slowly towards the Northeast over the next few days. A low pressure moving through South Central Canada will bring snow showers to the Northern Plains today.
Eastern Pacific: Low pressure is moving into the Central Gulf of Alaska and will bring increased winds and seas and more heavy snow to the Alaska region today.
Western Pacific: Typhoon Bopha has now been fairly stationary over the past few days and is more in a drifting pattern to the Southeast of Hong Kong China with winds near 80kts and a pressure back down to around 963mb and it has become stronger over the past day. Low pressure approaching the date line will begin to move into the Western Gulf of Alaska this weekend. Another low pressure area is over Northeast Russia which will slowly push eastward this weekend towards Northern Japan. A secondary low is moving out of Eastern Europe and towards Central Russia and will bring colder weather and snow possibly to the capital city of Russia this weekend.
Indian Ocean: An area of low pressure is moving through the Central Indian Ocean and should remain away from any land just increasing winds and seas in the open oceans.
Southern Hemisphere: A low pressure approaching the tip of South America will bring increased showers to the region.
Five Day Storm Index Outlook for December 7-11:
New York NY: The region will see showers along with a few snow showers over the next five days which puts the region under slight impacts for all five days.

Watertown SD: Today the area will see light snow followed by heavier snow on Saturday which will put the area in a Moderate impact. On Sunday blizzard conditions could be very possible putting the region into a Strong Impact area with blowing and drifting and falling snow in the range of upwards to 8 inches possible this weekend.
Denver CO: No impacts today, however this weekend some light snow will move through the area bringing slight impacts to the region.

Major Weather Impacts Discussion for December 7, 2012:
Day 1-3: A frontal boundary moving through the Northeast will bring showers and snow showers to the region today. High pressure will bring partly cloudy skies to the Southeast and Gulf Coast. Another frontal boundary moving through the Northern Plains will bring some areas of heavy snowfall to the region. The Pacific Northwest will be dealing with more rain and mountain snows today. The middle of this period will have a frontal boundary pushing across the Northeast bringing some snow and rain to the region and the Northern Plains will be dealing with a winter storm by Day 3. A developing low over Oklahoma will also start to spread moisture across the Southern Plains and Gulf Coast region while the Northwest deals with yet another frontal boundary.
Day 4-7: The start of this period will have the low moving into the Eastern Great Lakes and will have snow showers on the backside over the Western Lakes. Heavy rain will be ahead of it and also some strong to possibly severe weather will extend from the Tennessee River Valley into the Gulf Coast. Another frontal boundary will be clipping through the Northern Plains bringing light snow to the region. High pressure will start to control the weather along the West Coast and let the region finally start to dry out. The middle of the period will have a low off the Southeast Coast which will begin to bring showers to the region and slowly move northeastward. Another strong low will begin to move into the Plains by this time period as a weak frontal boundary moves back into the Northwest.
Day 8-12: The period will start with high pressure along the Eastern seaboard which will spread westward into the Gulf Coast region. An area of low pressure will move into the Northern Plains bringing another chance for light rain or snow, however with the high pressure over the Gulf it may become a dry front as it moves through the region. High pressure will ease the rains along the West Coast during this time. Towards Day 10 there will be an area of potential low pressure that will move along the Northern Gulf Coast. The period will end with high pressure in the Northeast and another frontal boundary along the Gulf Coast and the low pressure moving through the Northern Plains. Also we will see the onshore flow return to the Pacific Northwest. By the mid part of this period we will be watching another strong low move into the lower Mississippi River Valley bringing a chance for more severe weather along the Gulf Coast and also High pressure over the Southwest along with another frontal boundary pushing on shore over the Pacific Northwest. The middle of this period we will be dealing with a significant storm system in the Northeast which will bring plenty of rain and snow to the region and also the Great Lakes will see some significant snows.
Day 13-15: The start of this period will have high pressure over the East Coast bringing nice weather to the region, while another low pushes out of the Rockies into the Plains and will have rain and snow with it again possibly some heavy snowfall for the Dakotas. Moisture will also return to a good portion of the West and West Coast. The middle of this period we will have a low pressure in the Great Lakes bringing rain to the eastern lakes and moderate snows to the western lakes. There will also be the chance for severe weather along the Gulf Coast again. A very strong and cold high pressure area will develop over the Rockies which will aid in providing colder air to the frontal boundary and creating a heavy snow band on the backside of the system. Another frontal boundary will be moving onshore over the Pacific Northwest with heavy rains and mountain snows. The period will end with a significant storm along the East Coast.

Ask The Weatherman for December 7:
Question: Why do we get more thunderstorms in the summer?
Answer: Thunderstorms are more common during the summer and also the spring. The reason for this is that thunderstorms need some key ingredients to form and that is warm/moist air along with dry air and colder air from aloft to meet together. It also depends on where in the country you are because, in the winter, thunderstorms are very common along the Gulf Coast and Extreme Southeast. However, if you go out to the Plains they are more common in late spring and summer.

Green Energy Weather Report for December 7:
Wave Energy: The Pacific Northwest will again see moderate waves associated with the frontal boundary off the coast. The Northeast will also see a frontal boundary move through the region which will increase the waves in the area.
Solar Energy: Today the Gulf Coast and Southern Plains along with the Southwest will be the best places to get solar energy as they are all under the influence of high pressure today.
Wind Energy: There will be good winds along the backside of the cold front over the Northeast today and also some good winds blowing through the Northern Plains which will be good for wind energy and the Northwest again today will have good winds for energy.
Hydro-Energy: The showers and snow showers moving through the Northeast today will bring some good hydro energy to the region. The frontal boundary moving through the Northern Plains will create a snow base for future hydro uses. The Pacific Northwest again today will get more rainfall to fill the basins.
