Big Story Weather from December 11:

The last 24 hours aw heavy snowfall over the Eastern Great Lakes as the lake effect snows hammered the region with reports of snowfall over 1-2 feet in many places. The Arctic cold air held in place over a wide area from the Rockies eastward as temps over the Northern Plains struggled to get above zero yesterday.

Big Story Weather Discussion for December 12:

Surface Map 11AM: High pressure over the lower Mississippi River Valley will dominate the weather from the Plains to the East Coast, however the potential exist for more lake effect snows along the Eastern Lakes. High pressure over the Central Rockies will dominate the West Coast with partly cloudy skies with a slight warm up in store.

Surface Map 11PM: High pressure will slide into the Southeast overnight bringing another cool night to the region. This will dominate the weather back into the Plains and northward into the Northeast. A weak clipper system will bring a period of heavy snowfall over the Eastern Lakes. A second clipper system will drape into the Northern Plains bringing a few snow showers to North Dakota. A new storm system will begin to approach the Pacific Northwest and will bring a few rain showers to the region. High pressure over the Central Rockies will keep the rest of the West dry and cool.

Winter Weather: Lake effect advisory and warnings are still in effect for the Eastern Lakes as another round of heavy snowfall is possible over the region. Wind chill advisory/warnings are in effect from Northeast Minnesota into the Western Lakes. A frost/freeze advisory is still in place for portions of the southern valleys of California.

Flooding: There is a threat for river flooding in the Southeast Mississippi region over the next 24 hours.

Winds: The strongest winds will be over the Eastern Lakes which will help enhance the lake effect snows.

72hr Westward Storm Watch: Storm 1 is now approaching the Western coast of Canada. This will bring rain to the Pacific Northwest along with higher elevation snows. It will also bring rain and snow to Western Canada. Storm 2 is now pushing northeast of Hawaii. This storm will be a wind and sea maker over the next 24 hours. Storm 3 is sitting just to the west of the Kuril Islands and will begin pushing east over the next 2 days.

Ask The Weatherman for December 12, 2013:

Question: What is upslope fog?

Answer: This is a type of fog that forms as it moves up a hill. This type of fog needs clear skies and light winds to develop along with warm air running over colder air. One common place to see this type of fog is over Eastern Texas as two things take place here. First, the elevation rises from the Gulf of Mexico into the western part of the state. Secondly is that the Gulf of Mexico provides the warm air. This is most common during the fall and early spring time.

December 12, 2013 Storm Tracker Update:

SST Analysis (right image): The ENSO Phase remains in the neutral phase.

Today we are seeing warmer temps along the Eastern US. This is where we find the Gulf Stream – a warm ocean current transferring warm waters northward.

Eastern Pacific Ocean: Low pressure moving towards SOCAL will bring strong winds and high seas to the region today. A second low pressure moving over Western Canada will bring rain and snow to the Canadian Coast. This will also extend southward into the Pacific Northwest. A potent third low is moving into the Gulf of Alaska and will bring strong winds, heavy rains and heavy snows to Alaska. A fourth area to the northeast of Hawaii will bring strong winds and seas to the region.

Atlantic Ocean: Low pressure over Northeast Canada will bring snow showers to the region. Low pressure moving through Western Europe will bring snow showers to the region along with showers towards England. Low pressure moving out of Eastern Europe will bring showers and snow showers to the region.

Western Pacific: Low pressure to the west of the Kuril Islands will bring another day of showers and snow showers to the region.

Indian Ocean: The remains of Madi will be pushing onshore over Southeast India and near Sri Lanka.

Southern Hemisphere: Multiple lows moving through the basin. Impacts will be felt across a good portion of Southern Argentina as showers and thunderstorms move through the region. A second low will bring strong southeasterly winds to South Africa. A third low will bring impacts to portions of New Zealand.

Major Weather Impacts Discussion for December 12, 2013:

Day 1-3: High pressure over the lower Mississippi River Valley will bring partly cloudy skies to the region. This will extend into the Eastern US and also over the Plains. A second area of high pressure will bring partly cloudy skies and cool weather to the Rockies and most of the Western US. There will be some lake effect snows over the Eastern Lakes. This evening a small clipper system will bring a few snow showers to North Dakota, while a new storm system hits the Pacific Northwest will low elevation rains and higher elevation snows. Day two a storm system will develop over Southern Texas and will push showers and thunderstorms into the Gulf Coast. High pressure will dominate both coasts again. The period will finish with a low pressure moving up the Eastern US bringing rain and snows to the region, while high pressure dominates the Plains and the Western US.

Day 4-7: The period will start with high pressure over most of the country from west to east. The exception will be a weak clipper system that may provide the Northern Plains with a few snow showers. Day six the clipper system will push into the Great Lakes bringing more snowfall to the lakes; some of which may be heavy in lake effect snow bands. The period will finish with high pressure over most of the country. There will be another storm system entering the Pacific Northwest and the Northern Rockies bringing with it snow over the region and strong winds.

Day 8-12: The period will start with high pressure along the Eastern US and back into the Gulf Coast. A powerful storm system will be pushing into the Northern Plains and Rockies with heavy snows, while a warm front pushes into the Western Lakes bringing rain and snow to the region. A secondary low will push into the Southwest US bringing snow to the Southern Rockies which will be heavy as well. Day nine we will have a major winter storm on our hands with heavy snow extending through most of the Southwest into the Rockies and the Plains. Showers will extend from Texas into the Ohio River Valley and thunderstorms will extend along the Gulf Coast. Some severe weather will be possible. Day ten a major winter storm will be over the Great Lakes with heavy snows expected over the Lakes and also parts of the Upper Mississippi River Valley. Showers and snow showers will mix in over the Ohio River Valley. Thunderstorms and severe weather will be over the Gulf Coast. A new low will try to develop over the Southwest Gulf of Mexico. The strongest high pressure of the season will build in behind this storm bringing some very cold air southward over the Rockies. The period will finish with a major storm system over the Eastern US. Behind that will be yet another Arctic Air Outbreak for most of the US just in time for the holidays.

Long Range Outlook: The period will start with Arctic High pressure dominating most of the country with very cold weather again. The end of the period will have a new storm system developing in the Gulf of Mexico which will push rain, snow and ice northward into the Tennessee River Valley and the Gulf Coast. High pressure will still dominate the Plains with Arctic air. The period will finish with the Arctic air dominating most of the country.

Green Energy Report for December 12, 2013:

Wave Energy: There will be extreme amounts of energy over the entire West Coast as two separate storm systems begin to impact the region. The Gulf Coast will see very limited amounts of energy today, while the entire East Coast will have some energy today.

Hydro Energy: The best places for energy include the Pacific Northwest. This will be a combination of both short term and long term energy. The Great Lakes this will see moderate amounts of long term energy.

Solar Energy: There will be ample amounts of solar energy from the Southwest US into the Plains and spreading across the Gulf Coast and into the Southeast as high pressure dominates these areas today.

Wind Energy: The best places for wind energy today include the Pacific Northwest near the frontal boundary and then also over the Eastern Lakes as the cold northerly winds blow off the lakes.

Weather and Your Wallet for Minneapolis MN:

High pressure over the region will bring partly cloudy skies and very cold weather.

Dining: Today you will want to bundle up if you have plans to dine outside. It may be best to just take lunch to work to avoid the cold air.

Transportation: There will be no issues today on the roads or at the airports due to the weather.

Shopping: Plenty of sunshine today, just make sure to wear a winter coat before heading out to the stores for your holiday shopping.

Electricity: The region will see a high demand for heating today as high temps will only rise to around 22F. Overnight lows around 7F will give the region around 51HDD’s for the day.

Yard Work: There should be no problems with working in the yard today, however make sure to bundle up as it will be cold.

Construction: A cold day in store, however outside projects shouldn’t be impacted by the weather.

Outdoor Venues: If you’re taking the family pet for a walk, make sure to bundle yourself and the pet up before heading out as it will be cold still.
