Big Story Weather from December 16:

Heavy snow fell around the Lakes and Northeast again over the past 24 hours. The clipper system dropped snow across the Northern Plains and the small warming trend over the Plains continued.

Big Story Weather Discussion for December 17:

Surface Map 11AM: Low pressure pushing across the Great Lakes will bring snowfall to the region; some areas will see heavy snowfall. High pressure over the Rockies will dominate the weather from the West Coast into the Plains and the Gulf Coast region.

Surface Map 11PM: Low pressure will push off the Northeast coast overnight. This will create a heavy snowfall band from Boston northward. Lighter amounts will hit New York City. There will also be a rain/snow line across portions of the Mid-Atlantic. High pressure will slide into the Gulf Coast and Southeast providing another night of cool weather. High pressure over the Rockies will keep the region dry and this will also extend into the West Coast.

Winter Weather: There is a winter storm watch in effect for parts of Montana. Winter storm watches/warnings are in effect over the Northeast US, along with Maine to Boston where snowfall is expected to be the heaviest. There are also winter weather advisories in effect for both the Eastern Shores of Lake Michigan and parts of the Northeast and Mid-Atlantic. There is a frost/freeze area of concern for Northeast Florida around the Jacksonville area.

Winds: There will be an area of strong winds over portions of Eastern North Dakota.

72hr Westward Storm Watch: Storm 1 has now pushed into Western Canada bringing with it snow and gusty winds. This storm will push eastward over the next 24 hours. Storm 2 is becoming well organized as it pushes further into the Central Pacific and slowly towards the east. This storm will need to be watched for possible holiday travel impacts.

Ask The Weatherman for December 17, 2013:

Question: What is the wind flow around a low pressure?

Answer: When we look at low pressure on a weather map in the Northern Hemisphere, we note that the winds are from the south ahead of it and from the north behind the low. This allows warm air in front of the low and cold air behind the low. It also allows for moisture ahead of the low and dry weather behind the low.

December 17, 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.

Bottom Right Image: The latest image of Tropical Cyclone Amara currently over the open South Indian Ocean.

Eastern Pacific Ocean: An upper level low pressure to the southwest of SOCAL is being watched as it will push eastward over the next couple of days. Low pressure entering into Western Canada will bring rain and snow to the region. Low pressure moving through the Great Lakes will bring snow to the region and this will also extend into the Northeast.

Atlantic Ocean: Low pressure dominates a good portion of the ocean basin from the center of the low which is southeast of Iceland all the way along the cold front. This storm is moving slowly towards the east and should hit Western Europe later this week.

Western Pacific: Low pressure pushing towards the dateline will bring with it gale force winds, heavy rainfall and very high seas as it moves towards the east. Low pressure over Eastern China will bring rain and snow to the region as this low moves slowly towards Japan.

Indian Ocean: In the Southern Indian Ocean we have Tropical Cyclone Amara with winds around 35kts and pressure near 996mb. This storm will gain some strength as it continues to move west-southwest.

Southern Hemisphere: Multiple low pressures moving through the region will have impacts on Argentina with showers and some thunderstorms. A second low will bring snow showers to McMurdo Station in Antarctica. A third low pressure and its associated cold front will bring showers to Southwestern Australia.

Major Weather Impacts Discussion for December 17, 2013:

Day 1-3: The clipper system will move across the lakes today bringing snow to the Northeast US and the lakes region. High pressure over the Rockies will bring fair and cool weather to most of the Western US and also into the Plains. A second area of high pressure will bring partly cloudy skies to the Southeast and the Gulf Coast. Day two will see high pressure dominating most of the US. The storm system will push off the East Coast bringing another day of heavy snow from Boston to Maine. The period will end with high pressure pushing into the Eastern US, while a new storm system pushes into the Northern Rockies bringing heavy snowfall to the region.

Day 4-7: The period will start with the storm system moving into the Plains bringing cold temps and snow to the region. A new storm system will push into the Pacific Northwest as well. Day five the initial storm will push into the Great Lakes bringing rain and snow to the region. The cold front will extend to the Gulf Coast; thunderstorms and some severe weather will develop. The secondary low will push into the Southwest from the Baja. This will bring showers and some snow to the region. Day five the storm from the Southwest will push into the Gulf Coast region. This will trigger both heavy rain and another round of severe weather for the region. Showers will push northward into Boston and there will be a band of snow that sets up from Missouri to the Great Lakes. The period will end with another clipper system moving through the Northern Plains bringing with it light snow.

Day 8-12: The period will start with high pressure over most of the US. The clipper system will push into the Great Lakes bringing snow to the region. High pressure will slide in over the Northern Plains, however there will be a lee side trough that develops near Colorado and Nebraska that will trigger a few snow showers for the area. Day ten the overall weather pattern will see high pressure for most of the country. Day eleven a new storm system will enter the Pacific Northwest bringing rain and snow to the region. The period will end with the storm system slowly pushing into the Northern Rockies with rain and snow extending all the way back into the Northwest.

Long Range Outlook: The period will start with the low pressure sliding into the Southwest out of the Rockies. This will bring rain and snow southward. By New Year’s Eve we will be watching another major storm system hitting the Central Plains with rain, snow and some thunderstorms.

Green Energy Report for December 17, 2013:

Wave Energy: The entire West Coast will be at max levels for energy due to multiple storm systems approaching the coast over the Northwest and also the Southwest. The Gulf Coast will see slight amounts of energy due to high pressure in the area. The Southeast will see higher amounts of energy due to the cold front pushing towards the region from the north. The Mid-Atlantic to the Northeast will see moderate to extreme amounts of energy.

Hydro Energy: The best places of energy today will be from the Great Lakes into the Northeast near the clipper system.

Solar Energy: There will be ample amounts of solar energy from the Northwest to the Southwest and across most of the Rockies and Plains into the Gulf Coast along with parts of the Southeast.

Wind Energy: The best places for wind energy today will be over the Eastern Dakotas and also along the Great Lakes on the backside of the clipper and over the Northeast ahead of the storm system.

Weather and Your Wallet for Buffalo NY:

A clipper system pushing through the area will bring with it more light snow and moderate winds. This will create blowing and drifting conditions.

Dining: Today will be a good day to take lunch to work. Between the snow and the cold it will just be better to stay indoors today.

Transportation: There will be delays on the roadways today as the snow continues to fall and blow across the roads. There will also be delays at the airport as visibilities will be reduced along with the snowfall.

Shopping: If you have plans on heading out to do some shopping, take it easy on the roads as they will be slick.

Electricity: Today there will be a moderate demand for heating as high temps will only rise to around 29 and overnight lows will fall to near 24. This will give the region around 39HDD’s for the day.

Yard Work: If you are going out to move snow, take it easy as it will be cold.

Construction: There will be impacts to any outdoor projects today due to the snowfall and also the gusty winds.

Outdoor Venues: Today will be a great day to reschedule any outdoor plans you may have aside from walking the dog.
