redOrbit Meteorologist Joshua Kelly

Big Story Weather from December 13-15:

This past weekend saw significant snows over the Northeast and the Eastern Great Lakes. Minimal severe weather took place in Northern Florida. Warmth returned to the Northern Plains as places finally rose above the freezing mark for the first time in over a week.

Big Story Weather Discussion for December 16:

Surface Map 11AM: An Alberta clipper system will push across the Northern Plains this afternoon bringing around 1-3 inches of snowfall to the area. High pressure to the south of Texas will create partly cloudy skies over most of the Gulf Coast and the Southern Plains. A secondary high pressure will keep most of the Rockies and West coast dry and warmer today.

Surface Map 11PM: This evening the clipper system will push into the Great Lakes bringing snowfall to the region. Some places could see over 6 inches. High pressure will keep the Southern Plains and the Gulf Coast partly cloudy. A second high pressure over the Rockies will keep the region dry and warmer. This will extend also into the West Coast.

Winter Weather: A frost/freeze watch is in effect for the Corpus Christi Texas metro region. Winter storm watches/warnings are in effect for Northern Maine where snowfall is expected in excess of 6 inches today. A winter weather advisory is in effect for the Lake Michigan region which could see additional snowfall overnight. Heavy snowfall is also possible downwind of Lake Erie this evening as some places could see an additional 6 inches or more.

Winds: The strongest winds today will be found over the Great Lakes near the clipper system and also over the Northeast on the backside of the storm system.

72hr Westward Storm Watch: Storm 1 is in the Gulf of Alaska and is bringing heavy rains to the Coastal Canada along with heavy snowfall in the higher elevations. Snowfall is also heavy over Southern Alaska near the storm. Storm 2 is now pushing to the east of Japan and will make its way over the Pacific towards the Western US by later in the week.

Ask The Weatherman for December 16, 2013:

Question: What are the two types of pressure systems on the weather map?

Answer: When you look at a weather map, it can be broken into two types of pressure. There is either high pressure or low pressure. High pressure means fair and colder weather, while low pressure means warmth and rain, hurricanes, snow, blizzards, etc.

December 16, 2013 Storm Tracker Update:

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

SST Discussion: A large warm pocket over the Indian Ocean is supporting a possible tropical wave that may develop later this week.

Eastern Pacific Ocean: An upper level low off the coast of SOCAL will push across later this week and impact the Southern Plains and Gulf Coast. Low pressure pushing into the Gulf of Alaska will bring significant weather to Western Canada.

Atlantic Ocean: Low pressure pushing off the Northeast US is bringing heavy snowfall to Maine. A second low pressure pushing into Western Europe will bring snow and rain to the region. A dissipating storm system will bring showers and possibly snow showers to Northern Africa.

Western Pacific: Low pressure moving into Central Russia will bring snow to the region. Low pressure pushing away from Japan will bring rain and snow to Northern Japan and the Kuril Islands. Low pressure over Eastern China will begin to push towards Shanghai. This will bring rain and higher elevation snows to the region.

Indian Ocean: There are two waves being watched for possible tropical development over the next few days.

Southern Hemisphere: Multiple areas of low pressure moving across the region. The first is moving through Southern Argentina. This area will see rain and higher elevation snows especially in Chile. The second will bring a few showers and strong southeast winds to South Africa. The third low pressure is pushing towards Southern Australia. Expect to see increasing winds for today and a few showers around Perth.

Major Weather Impacts Discussion for December 16, 2013:

Day 1-3: A clipper system will push through the Northern Plains and into the Great Lakes before heading into the Northeast overnight. This will bring areas of moderate snowfall across the entire area. High pressure will keep the weather cool and dry from the Southeast to the Gulf Coast and back into the Southern Plains. A second area of high pressure will keep the West and the Rockies mostly dry and cool. Day two the clipper system will push into the Northeast bringing a pocket of heavy snowfall from Boston northward. High pressure will dominate the Southeast all the way back into the Plains, while another weak clipper system pushes into the Northern Plains. The period will end with a new storm system pushing into the Northwest and Northern Rockies. Expect to see heavy snowfall setup with this.

Day 4-7: The period will start with the low pressure moving into the Great Lakes bringing rain and snow to the region. An upper level low will push towards the SOCAL region bringing rain to the area. Day five another storm system will push into the Northwest and will interact with the upper level low over the Baja. A few showers will linger around the Gulf Coast, while a few snow showers will be seen over the Northeast. The period will finish with a significant storm system over Southern Texas. Expect to see rain from Houston northeastward. Expect rain, snow and possible heavy snowfall on the backside of this over northwest Texas into the Mid-Mississippi River Valley.

Day 8-12: The period will start with the major storm system pushing into the Ohio River Valley. Expect to see rain from the Northeast all the way to the Gulf Coast. There will even be some thunderstorms along the Gulf Coast. We will also see a heavy snow band setup over the Great Lakes back into the Mid-Mississippi River Valley during this time. Day nine another clipper system will push through the Northern Plains. Day ten most of the country will be dominated by high pressure. The period will finish with a clipper system over the Northern Plains. Look for high pressure to dominate the rest of the country.

Long Range Outlook: The period will start with a strong high pressure center over the Northern Plains, while an area of low pressure begins to develop near Eastern Mexico. The middle of the period will have low pressure pushing across the Gulf of Mexico towards Florida. This will bring heavy rains to the Gulf Coast and into the Southeast. The period will end with another major storm moving up the Eastern US around New Years. This will impact travel along the entire East Coast with heavy rains and snowfall. High pressure will build in over the Northern Plains with cold air.

Green Energy Report for December 16, 2013:

Wave Energy: There will be significant wave energy amounts along the entire West Coast due to the approaching frontal boundaries. The Northern Gulf Coast and the Southeast will have lower amounts of energy today. The Mid-Atlantic to the Northeast will see significant amounts of energy as low pressure pushes away from the coast.

Hydro Energy: There will be long term energy buildup over the Northern Plains and into the Great Lakes along with the Northeast as all places will see moderate snowfall over the next 24 hours.

Solar Energy: There will be ample amounts of solar energy across most of the Western US and into the Rockies. The second place of great solar energy will be across the Southern Plains and into the Gulf Coast and the Southeast as high pressure dominates these regions.

Wind Energy: The strongest wind energy will be located along the clipper system. Look for strong winds from the Northern Plains into the Great Lakes pushing into the Northeast overnight.

Weather and Your Wallet for Sioux Falls SD:

A clipper system will pass to the north. Winds will be strong behind the front over the region.

Dining: There will be no issues with enjoying a meal at the park, however dress warm as it will be cold.

Transportation: There will be impacts on the roadways for high profile vehicles as the winds will be strong. There will also be small delays at the airport due to the strong cross winds.

Shopping: There will be no issues with doing some holiday shopping. Just make sure to wear your jacket as it will be cold.

Electricity: The region will see a moderate use of heating today as the high temps will be around 32F and low temps near 28F. This will bring around 35HDD’s for the area.

Yard Work: There will be no issues with working outside today. Just make sure to bundle up and take frequent breaks if shoveling snow.

Construction: There will be some impacts today with construction projects, especially for any elevated projects due to the strong winds.

Outdoor Venues: Today will be a cold but sunny day to get out to the Falls Park and enjoy a walk with the family pet.
