Big Story Weather from December 25: This will be a Christmas that the Gulf Coast will not soon forget. It was a very active day with many tornadoes (roughly 25 of them confirmed) touching down in the region. The second big story of the day was the winter storm that hit Oklahoma, Texas and Arkansas with many places seeing over 6 inches of snow.

Weather Outlook for December 26: Low pressure moving into the Ohio River Valley will be responsible for creating another day of blizzard-like conditions from Cleveland southward into Kentucky and westward into Indiana with some places getting over 8 inches of snowfall. There will also be a window of severe weather along the Carolina coastline as the warm sector moves through the region, while a wintry mix will be found along the Mid-Atlantic region for places like Baltimore. A very cold area of high pressure will slide across the Northern Plains today bringing some very cold air to the region. This will extend down towards the Southern Plains and into the Gulf Coast region. Another area of low pressure is developing over the Southwest bringing some higher elevation snows to Northern Arizona and into the Rockies. A frontal boundary off the coast will bring showers to the West Coast. Below is the weather for a few select cities.

Baltimore MD: Cloudy with Rain/Snow: 41F
Atlanta GA: Partly Cloudy: 42F
Rapid City SD: Partly Cloudy: 22F
Denver CO: Cloudy with evening Snow: 30F
Seattle WA: Cloudy/ morning Showers: 46F

International Weather Outlook for December 26: High pressure building in over Japan will bring partly cloudy skies to the region. This will extend westward back into the Koreas and Eastern China. A weak trough will move through Hong Kong bringing a slight chance of showers to Southeast China. High pressure over Russia will bring very cold air to the region. Low pressure moving through Central Europe will bring showers to the south and snow to the northern regions. High pressure will bring partly cloudy skies to Spain and France. Low pressure will bring showers to England. An area of high pressure will bring nice weather to Southern Australia, while the North could be dealing with a few showers. Here is the forecast for a few select international cities.

Tokyo Japan: Partly Cloudy with a low near -2C
Hong Kong China: Partly Cloudy with a few showers and a low near 14C
Singapore: Partly Cloudy and a low near 25C
Madrid Spain: Partly Cloudy with a low near 7C

Atlantic Basin: Low pressure moving through Eastern Europe will bring showers to the south and snow to the north in the region. Another low pressure moving into England will bring showers to the region. A low pressure area is moving through the Northern Atlantic and will slowly shift towards Greenland and Iceland. Another area of low pressure moving up the East Coast of the US will bring snow, rain, severe weather to the region.

Eastern Pacific: Low pressure moving into the Southwest United States will bring snow and rain to the region. Another weak area of low pressure is moving across the Pacific towards Southern California. A third low pressure is moving through the Eastern Gulf of Mexico and will move towards the Canadian Pacific region over the next couple of days.

Western Pacific: Low pressure is moving across the Northern Pacific and will begin to move into the Western Gulf of Alaska over the next couple of days. Low pressure moving through Central Russia will bring showers and snow to the region. Tropical Storm WuKong is moving over the Philippines and will slowly move towards Southeast Asia with winds around 35kts and pressure of 1000mb.

Atlanta GA: There are no impacts forecasted until the 29th when then a chance of showers will move through the region bringing a slight impact to the region.

Rapid City SD: The period will start with no impacts, however by the 27th and 28th the region will see a slight impact from some snow showers moving through the area.

Denver CO: A few snow showers today and tomorrow will bring a slight impact to the region, followed by the remainder of the period being impact free.

Seattle WA: Showers will impact the region today and tomorrow with slight impacts followed by a tranquil finish to the period with no impacts forecasted.

Seattle WA: The period started about 2 degrees above average before falling to around 1-3 degrees below average for the remainder of the period.

Major Weather Impacts Discussion for December 26, 2012:

Day 1-3: Low pressure moving up the Ohio River Valley will bring plenty of severe weather into the Carolinas along with wintry mix to the Mid-Atlantic region and heavy snows and blizzard conditions to the Ohio River Valley. High pressure over the Northern Plains will bring nice and cold weather to the region and this will extend southward into the Gulf Coast region and Southern Plains. Another newly formed low will begin to impact the Southwest. The period will end with another low pressure system moving through the Gulf Coast and this will bring showers and snow showers into the region and will extend northward into the Ohio River Valley. High pressure will be over the Plains and Rockies bringing colder weather to the region. Another weak frontal boundary will approach the West Coast.

Day 4-7: The period will start with a low moving up the Mid-Atlantic region while high pressure will build in over the Gulf Coast and Ohio River Valley, while another low pressure system moves into the Northern California region. The end of the period will have another low moving out of Mexico and towards the Gulf Coast region bringing some very cold rain to the region and maybe some mix precipitation for some places. High pressure will be along both coasts.

Day 8-12: The period will start with the low moving through the Ohio River Valley into the Northeast with plenty of rain on the south side of the front and snow up in the Great Lakes region. A strong area of high pressure will be over the Western United States. The middle of the period will find high pressure along the East Coast along with another frontal boundary moving over the Pacific Northwest. The period will end with a weak frontal boundary moving across the Northeast, while high pressure will build in over the Plains and also another strong high over the Northern Rockies.

Day 13-15: The period will start with some lake effect snows in the Northeast. Otherwise two large high pressure centers will be in control of the weather from the East Coast to the West Coast. The middle of the period will have high pressure in the Northeast along with another frontal boundary developing in the Gulf of Mexico and a very strong high pressure area over the Southwest and a frontal boundary approaching the Pacific Northwest. The period will end with some small Alberta Clippers moving through the Northern Plains, while the rest of the country will be quiet. Towards the end of the period, the majority of the Southern United States will see a pattern shift which will allow the frontal systems to stay north of the region as two powerful high pressure systems will build in to the region and keep most of the weather to the Northern Plains and also the Great Lakes along with the Northeast.

Ask The Weatherman for December 26:

Question: What time of day do tornadoes most often form?

Answer: Tornadoes form at any time of the day when the conditions are favorable. However, records show that many tornadoes form in the afternoon. A second peak time occurs in the morning. The biggest thing depends on what type of tornadoes they are. If they are formed from a super-cell, they will be most likely in the afternoon. If they are along a front they can form in the morning as well. Remember the big ingredients that are needed for tornadoes to form include cold air in the upper levels, dry air in the mid-levels and very warm moist air in the lower levels.

Green Energy Weather Report for December 26:

Wave Energy: The frontal boundary along the West Coast will bring some moderate wave energy to the region. Stronger winds over the Northern Gulf will also create a region of wave energy and then along the Southeast coast ahead of the front will be another region.

Solar Energy: The Plains from North Dakota to Texas will be the best region for solar energy today.

Wind Energy: The Pacific Northwest will have some stronger winds which could create a nice wind energy source today. Winds over the lower Mississippi River Valley behind the front will also create a chance for good wind energy as well as in and the Ohio River Valley area.

Hydro-Energy: The rain showers moving in along the West Coast and the mountain snows will make this region a great hydro source for today both short term and long term. The developing low over the Southwest will also bring some rain and snows to this region. The frontal boundary moving up the East Coast will bring plenty of rain to the region and then back in the Ohio River Valley we will see plenty of snowfall which will add to the longer term hydro pack.

December 26 Weather and Your Wallet (Austin TX):

Dining: A tad bit cold this morning if you have plans to eat outside. However, if you have plans to take a lunch break outside, put on a light jacket.

Transportation: No issues today as the skies will be mostly cloudy with no precipitation forecasted for the region.

Shopping: Bundle up if you have plans to get out and catch the after Christmas holiday sales.

Electricity: A significant use of heating will be needed throughout the night as temps drop back into the upper 20´s, looking for about 29HDD´s for the area.

Yard Work: Should be a good day to get out and clean up all the leaves.

Construction: A good day to work on those outdoor construction projects, just wear your heavy clothing.

Outdoor Venues: A nice day to enjoy a walk in the park as long as you bundle yourself and pets up.
