Big Story Weather from December 18:

Significant snow fell over the Rockies yesterday with some places getting over 6 inches. Cold air settled in over the Southeast US as frost and freeze watches/warnings were posted for parts of Florida and Georgia.

Big Story Weather Discussion for December 19:

Surface Map 11AM: High pressure pushing off the East Coast will bring another nice day to most of the Eastern US, while the next storm system pushes into the Southwest US. This will bring snowfall over the Northern Rockies and the Northern Plains extending back into the higher elevations of Nevada and Utah as well. The West Coast will enjoy a partly cloudy day for the most part.

Surface Map 11PM: High pressure will slide into the Atlantic. This will allow for return flow to setup from the Gulf Coast to the Eastern US and cause temps to warm up and more moisture to return to the region. Low pressure pushing into the Central Plains will bring snow to the Dakotas and eastward into the Great Lakes. A rain/snow line will setup from Northeast Oklahoma into Illinois. Showers will be found over the Southwest. An Arctic high pressure will slide into the Northern Plains dropping temps to around 0 to -10F for the region. The Western US will enjoy partly cloudy skies.

Winter Weather: A large area of winter storm watches/warnings and advisories in effect over most of the Rockies and into the Northern Plains. Most places will see around 2-9 inches of snowfall. Winter weather watches/warnings in effect for parts of Arizona and New Mexico for the higher elevations with snowfall totals around 6 inches. Freezing rain impacts will be felt from Iowa to the Western Lakes. Frost/freeze warnings are in effect for parts of Georgia and Northern Florida.

Flooding: Flooding is possible from Oklahoma to Ohio. This region will see very heavy rainfall over the next few days with some places getting more than 5 inches.

Winds: The strongest winds will be behind our frontal boundary over the Rockies and the Northern Plains.

72hr Westward Storm Watch: Storm 1 is now in the Gulf of Alaska bringing rain/snow to Western Canada and snow showers over Southern Alaska. This storm will continue to move eastward over the next 24 hours. Storm 2 is pushing towards the Aleutian Islands bringing strong winds and seas and showers to the region. Storm 3 is pushing away from Japan and will be heading in a north-northeastward direction.

Ask The Weatherman for December 19, 2013:

Question: What is meant by the term “zonal flow?”

Answer: When meteorologists mention the words zonal flow, they are talking about the upper level wind pattern – usually around 200-300mb charts around 20-30,000ft above the ground. Here is where we find the jet streams that are responsible for moving the weather. When the pattern is zonal, it means that everything is flowing from west to east at rapid speeds.

December 18, 2013 Storm Tracker Update:

Top Left Image: Tropical Cyclone Bruce. Bottom Right Image: Tropical Cyclone Amara.

Eastern Pacific Ocean: Low pressure moving into the Gulf of Alaska will bring high seas and strong winds to the islands. Low pressure pushing into Western Canada will bring showers and snow showers to the region. Low pressure pushing into the Southwest US will bring rain and snow to the region.

Atlantic Ocean: Low pressure near the East Coast of Canada will bring snowfall to the region. This will extend into Greenland and Iceland. Low pressure moving through Northern Europe will bring snowfall to the region and showers to England. Low pressure off the coast of Northern Africa will bring showers to the region including the Cape Verde Islands.

Western Pacific: Low pressure moving through Central China and Russia will bring snowfall to the region along with another round of cold weather. Low pressure moving along the coast of Tokyo will bring showers to the region and snow showers to Northern Japan.

Indian Ocean: Located in the Southern Indian Ocean is Tropical Cyclone Amara with winds around 105kts and pressure near 944mb. Tropical Cyclone Bruce has winds near 75kts and pressure near 967mb. Both systems remain over the open ocean and are no immediate threat to land.

Southern Hemisphere: Multiple lows moving through the basin. Impacts are being felt over Southern Argentina with gusty winds and a few showers. The second impacts are being felt along South Africa with a few showers and strong southeast winds. A third storm system is impacting Southern Australia with showers and thunderstorms.

Major Weather Impacts Discussion for December 19, 2013:

Day 1-3: High pressure along the East Coast will bring return flow to the Southeast and Gulf Coast. This will start the warming trend ahead of the next storm. Showers will extend from the Southwest, while snowfall will be found over the Rockies and the Northern Plains before moving into the Great Lakes overnight. Snow showers will extend from the Southwest into Nevada and Utah as well and a few showers will be over SOCAL. The Pacific Northwest will see partly cloudy skies for the most part. On day two the showers and snow showers will move into the Great Lakes, while a second low deepens over the Southwest. The period will end with a major storm system over the Ohio River Valley with heavy rain extending from Ohio to the Gulf Coast. Severe weather will be possible over Louisiana and Mississippi into Alabama.

Day 4-7: The period will start with showers extending from Maine to Florida with areas of heavy rainfall possible. High pressure will dominate the Plains and the Gulf Coast extending into the West. By day six a weak clipper system will move through bringing snow showers to the Great Lakes in time for the holidays.

Day 8-12: The period will start with a tranquil weather pattern over most of the US. However, there will be a new storm system entering the Pacific Northwest. Day ten a clipper system will bring light snow from the Plains to the Great Lakes, while the rest of the country will see partly cloudy skies and high pressure. By day eleven another storm system will develop in the Gulf of Mexico. This will bring areas of heavy rain and also the potential of severe weather along the Gulf Coast, while a strong high pressure builds in over the Northern Plains. The period will end with the low pressure moving up the Eastern US. This will bring rain and some snow to the region. High pressure will dominate the rest of the country.

Long Range Outlook: The period will start with a low moving up the Eastern US bringing rain and snow, while high pressure dominates the weather from Ohio to the Gulf Coast. A new storm system will push into the Northern Plains with snow. Behind that another shot of Arctic air will push into the region bringing another round of cold weather. The middle of the period will have high pressure dominating the weather from the Plains to the East Coast. This high pressure will bring more cold air into the region with it as well. A new storm system will begin to develop over the Southwest US. The period will end active with a storm system extending from the Ohio River Valley to the Gulf Coast. Showers, thunderstorms and some severe weather will be found along with snowfall on the colder side. A new storm system will be pushing into the Pacific Northwest with rain and higher elevation snows as well.

Green Energy Report for December 19, 2013:

Wave Energy: There will be high amounts of energy along the entire West Coast as multiple storm systems are moving through the region. The Northern Gulf Coast will see an increase in energy today as onshore flow begins to impact the region. The Southeast will have energy today as onshore flow sets up over parts of the region. The Northeast and Mid-Atlantic will see moderate amounts of energy today.

Hydro Energy: There will be ample amounts of short-term energy and long-term energy stretching from the Great Lakes to the Northern Plains and then over parts of the Rockies extending into the Southwest US.

Solar Energy: The best places for solar energy today will be from the Southern Plains into the Gulf Coast and over the Southeast expanding into parts of the Ohio River Valley and the Mid-Atlantic as well.

Wind Energy: The best places for wind energy today will be right behind the frontal boundary expanding from the Great Lakes back into the Southwest.

Weather and Your Wallet for Rapid City SD:

Today the region will see cloudy skies with snow and gusty winds. This will lead to blowing and drifting snow.

Dining: There will be impacts to any outdoor lunch plans today. It would best to take your lunch to work.

Transportation: The region will have impacts on the roads, especially in places that have high drifting snow across the roads. There will also be delays at the airport for both de-icing and also reduced visibilities forcing delays in flights.

Shopping: Today will be a good day to just get what you need and ride the snow out at home. Limit your time in the elements as it will be very cold.

Electricity: High amounts of energy will be needed today as high temps only hit 22F and overnight lows fall to around 8F. This will give the region around 50HDD’s for the day.

Yard Work: If you’re heading out to shovel the snow off the sidewalks, make sure to give yourself plenty of time and take it slowly to avoid any health impacts.

Construction: Today will be a good day for the indoor projects.

Outdoor Venues: Spend as little time as possible in the outdoors today as the snow, wind and cold air will make it dangerous to be out for long period of times. Bring your pets indoors too.
