Big Story Weather from December 20-22:

A very active weekend was seen across a good portion of the country. Heavy rainfall was found from the Ohio River Valley to Gulf Coast with some places seeing between 4-9 inches. Heavy snowfall was seen over portions of the Western Lakes with some place seeing 3-7 inches. Record setting warmth hit the Gulf Coast with places pushing near 80F, while cold weather hit over the Northern Rockies and Plains with places not even getting above zero again and wind chill values near -35F. Lastly, there were a few tornado reports across multiple states over the Gulf Coast and Southeast along with damaging winds and some hail reports.

Big Story Weather Discussion for December 23:

Surface Map 11AM: Low pressure moving into Maine this morning will set the stage for snow over in the northern part of the state. Rain and snow will extend from southern Maine to near Boston. Showers will extend along the rest of the Eastern US. A cold Arctic high will build in over the Plains bringing temps and wind chill values well below zero for the region. High pressure over the Rockies will keep the Southwest dry and mild. A clipper system entering the Northern Rockies will be the focus for more snowfall over the region.

Surface Map 11PM: Low pressure will move into the Northeast and off the coast. This will bring another evening of light snow over most of Maine extending into Boston. Showers will still impact the Mid-Atlantic to Florida. High pressure will slide into Arkansas and will bring colder weather to the Gulf Coast with low temps falling into the 30’s and 40’s. Wind chill values over the Upper Midwest and the Ohio River Valley will fall below zero. High pressure over the Southern Rockies will bring mild, dry weather to the Southwest. The clipper system will move out of the Northern Rockies and towards the Plains with snow and some places may see slightly warmer weather.

Winter Weather: There is a winter weather advisory out for the Rockies in Idaho and Western Montana. Snowfall should be in the 3-6 inch range. There is also a winter weather advisory out for portions of Eastern Montana into the Western Dakotas for a combination of rain, snow and freezing rain. A third winter weather advisory in effect for Northern Maine where some snowfall is forecasted. There is also a freezing rain advisory in effect for Southern Maine to Boston due to the combination of rain and snow. There is a combination of wind chill advisories and warnings in effect over the Northern Plains into the Upper Mississippi River Valley where the combination of below zero temps are leading to wind chill values near -40F.

Flooding: There are flood watches/warnings in effect from Western New York all the way south into Eastern Indiana from this past weekend’s heavy rainfall. This has led to flooding of streams and rivers. There is also a flood watch out for a line from Maryland to Alabama. This area is in for a combination of more rainfall and the flooding that is already taking place from this past weekend.

Winds: There are small craft impacts forecasted for the Great Lakes.

72hr Westward Storm Watch: Storm 1 is now in the Gulf of Alaska bringing rain and snow along with gusty winds to Southern Alaska. This storm will push into Western Canada over the next 24 hours. Storm 2 is very well defined and strong as its now moving out of the Kuril Islands and towards Alaska. This storm has a large area of winds in excess of 50mph and it will create large-scale marine impacts over the region.

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

Eastern Pacific Ocean: Low pressure moving across Western Canada will push snow showers over the Northern Rockies and Plains today into tomorrow. Low pressure near the Gulf of Alaska will bring rain and snow to Southern Alaska. A third low pressure to the east of Hawaii is slowly moving towards the east and will impact the SOCAL region later in the week.

Atlantic Ocean: Low pressure near the Northeast US will bring rain and snow to the region today. A second low pressure area is moving towards Iceland with rain and snow for the region. This will also extend into the Western Europe region.

Western Pacific: Low pressure moving through Central China will bring snow to the region. A second low pressure area pushing out of the Kurils will bring strong winds and high seas to the region.

Indian Ocean: Tropical Cyclone Amara continues to turn in the South Indian Ocean with winds around 40kts and pressure near 993mb. The storm will continue to track southward and loose strength over the next 24 hours. Tropical Cyclone Bruce located in the Southern Indian Ocean still has winds around 95kts and pressure near 952mb. This storm will also slowly push southward and weaken over the next few days.

Major Weather Impacts Discussion for December 23, 2013:

Day 1-3: Low pressure moving along the Eastern US will bring snow to Maine and a rain/snow mix to Boston. Further south along the coast it will bring a cold rain. The Arctic high pressure has begun working its way southward over the Plains and will be moving towards the Southern Plains this evening. This high pressure will bring very cold temps along with very dangerous wind chill values to many places. High pressure over the Southern Rockies will keep the Southwest dry and cool. A clipper system will move into the Northern Plains and Rockies bringing some ice and snow to the region. The period will finish with the clipper system moving through the Great Lakes bringing some light snow to the region, while the rest of the country will be under high pressure.

Day 4-7: The period will start out very tranquil as high pressure dominates most of the country. Day six another clipper system will enter into the Northern Plains with some light snowfall. The period will finish with the clipper system moving over the Great Lakes, while the rest of the country will under high pressure.

Day 8-12: The period will start very tranquil as high pressure continues to dominate most of the country, while a clipper system brings some light snow to the Great Lakes. Day ten a new storm system will try to develop over Mexico and push rain showers into the Gulf of Mexico and the Northern Gulf, while another strong Arctic High dominates a good portion of the country. The period will finish with a storm system in the Gulf of Mexico moving northward along the East Coast, while high pressure dominates the rest of the country.

Long Range Outlook: The period will start with a storm system along the Eastern US and also another powerful storm system pushing into the Northwest US. The period will finish with a strong storm system moving up the Eastern US, along with another storm system in the Gulf of Mexico and a very strong cold high pressure over the Plains and the Great Lakes.

Green Energy Report for December 23, 2013:

Wave Energy: There will be extreme amounts of energy along the entire West Coast due to the strong storm system and the high pressure interacting off the coast. There will be moderate amounts of energy over the Northern Gulf as the cold front begins to push through. The entire East Coast will be dealing with extreme amounts of energy today as the cold front begins to push through the region.

Hydro Energy: There will be ample amounts of short and long term energy over Maine, while from Boston to Florida the region will see short term energy. There will also be long term energy over the Northern Rockies into the Plains along the clipper system.

Solar Energy: The best place for solar energy today will be over the Upper Plains region and back into the Southwest and over the Southern Plains near the high pressure center.

Wind Energy: The best place for wind energy today will be over the Great Lakes behind the cold front and ahead of the Arctic High. A second place will be from the Mid-Atlantic to the Gulf Coast behind the frontal boundary. A third location will be over the Northern Rockies behind the clipper system.

Weather and Your Wallet for Chicago IL:

Strong northerly winds will push in with the next High pressure center. This will bring very cold conditions with wind chill values at or below zero.

Dining: Today will be a good day to take lunch to work as it will be cold outside.

Transportation: There will be no weather impacts at the airport or on the roadways today.

Shopping: If you are heading out to do some shopping today, make sure to bundle up as it will be very cold.

Electricity: The region will have a very high demand for heating all day as high temps will only get to around 20F and low temps will fall to near 6F. This will give the region a forecasted HDD of around 52.

Yard Work: There should be no impacts other than make sure to bundle up.
