redOrbit Meteorologist Joshua Kelly
Big Story Weather from December 17:
The Great Lakes and the Northeast dealt with another day of heavy snowfall and a new storm entered into the Northern Rockies.
Big Story Weather Discussion for December 18:
Surface Map 11AM: High pressure will slide into the Southeast US allowing for the slow return of southerly flow along the Gulf Coast which will warm temps back up today. Low pressure will begin to develop in the Rockies this afternoon and will bring snow showers over the Northern Rockies from Idaho to Montana; snowfall may be heavy at times. High pressure over Southern Idaho will dominate the rest of the Western US with partly cloudy skies and cool weather.
Surface Map 11PM: High pressure will slide over South Carolina as it continues to push southeastward. This will make for a warmer night along the Southeast and Gulf Coast. The low pressure over Colorado will finally start to pick up a little bit more moisture which will allow for more snowfall from the Western Dakotas back into Montana and Idaho overnight. High pressure over Southern Idaho will keep the rest of the West dry and cool overnight.
Winter Weather: There will be some remaining snowfall over Southern Maine this morning with additional accumulations. A winter weather advisory is in effect from Western Montana to the Western Dakotas for snowfall amounts of 4-6 inches. A winter storm watch is in effect for portions of Nevada with the possibility of heavy snowfall. Lake effect snow will also be found downwind of the two eastern lakes today.
Fog: There will be dense fog over Southeast Texas and into Southern Louisiana associated with the warmer air moving in over the cooler land.
Winds: The strongest winds will be over Lake Michigan and also over the West Coast behind the approaching storm system.
72hr Westward Storm Watch: Storm 1 is now located near the Western islands of Alaska and will continue to push east-northeast over the next 2 days towards Alaska. Storm 2 is now along the east coast of Japan and will make its way slowly northeastward over the next couple of days.

Ask The Weatherman for December 18, 2013:
Question: What is the wind flow around high pressure?
Answer: When you look at the big blue H on the weather map, what type of wind flow and weather does it provide? The wind flow for the high is out of the north on the eastern side of it, while the western side of it has southerly flow. When a high pressure comes in from the north, it's always cold because of the northerly winds. When it's leaving, the warmer winds start to move back in. Be advised it's the exact opposite in the Southern Hemisphere.

December 18, 2013 Storm Tracker Update:
Top Left Image: Tropical Cyclone Bruce.
Bottom Right Image: Tropical Cyclone Amara.
Eastern Pacific Ocean: Low pressure near the Baja will continue to slowly push eastward over the next few days. Low pressure pushing into the Northern Rockies will start to bring snowfall to the region. A third area of very strong low pressure is now pushing into the Gulf of Alaska.
Atlantic Ocean: Low pressure moving along the Northeast US will bring more snow to Maine and Eastern Canada this morning. Low pressure pushing towards England will bring showers to the region. Low pressure moving across Central Russia will bring snow and colder temps to the region.
Western Pacific: Low pressure moving into Eastern Russia will bring snowfall to the region as it moves eastward. Low pressure off the coast of Japan will bring rain to Tokyo and some snow to the Northern part of Japan.
Indian Ocean: Located in the Southern Indian Ocean we now have Tropical Cyclone Amara with winds near 80kts and pressure around 963mb. This storm is moving west-southwestward away from land at this time. Tropical Cyclone Bruce has developed overnight and is moving west-southwest with winds around 50kts and pressure near 985mb.
Southern Hemisphere: Multiple areas of low pressure are moving through the basin. Impacts are being felt over Argentina in the form of showers and thunderstorms. A second low is bringing gusty southeast winds to South Africa. A third low is bringing snowfall to portions of Eastern Antarctica. Another low is impacting Southwest Australia with showers and isolated thunderstorms.
Major Weather Impacts Discussion for December 18, 2013:
Day 1-3: An area of low pressure will push along the Southeast coast of Maine. This will bring another morning of heavy snowfall to the region. High pressure near the Carolinas will bring partly cloudy skies to the rest of the Eastern US, the Ohio River Valley, and southward into the Gulf Coast and over most of the Southern and Central Plains. Low pressure moving into Southwestern Canada will bring snow showers to the Northern Rockies this afternoon spreading into the Northern Plains overnight. Another area of high pressure will dominate the weather from Southern Idaho into the Southwest with light winds and cooler temps. Day two the storm system will get better organized as a new low develops in the Colorado Rockies. This will allow for snowfall to spread from the Northern Rockies into the Northern Plains; some heavy snowfall will be possible. The period will finish with the storm pushing into the Great Lakes bringing snowfall to the region, while an upper level low pushes into the SOCAL region bringing rain and higher elevation snows to SOCAL.
Day 4-7: The period will start with low pressure and the associated cold front extending from the Northeast all the way back into Texas. Along this front look for showers and a few thunderstorms for the southern part, while rain and a few snow showers will be found over the northern part. Low pressure will also be developing in the Southwest part of Texas, while a strong Arctic high pushes into the Northern Plains bringing another round of cold weather. Day five will have showers extending from Boston to Dallas, while thunderstorms will be over the Southern Plains and the Gulf Coast region. The potential is there for some severe weather, especially for Louisiana and Mississippi, while a small pocket of rain and snow develops over Northeast Oklahoma. High pressure will be over the Northern Plains. The period will finish with the storm system moving along the East Coast with showers and a few snow showers over the northern part.
Day 8-12: The period will start with high pressure dominating most of the country. Day ten looks to be fairly tranquil as well as high pressure will dominate most of the country. The period will finish with a clipper system bringing snowfall to the Great Lakes. A new low will form in Southern Texas bringing showers to the Gulf Coast and another strong high pressure will settle in over Colorado.
Long Range Outlook: The period will start with a Gulf Low moving up over Florida. Look for heavy rainfall, strong winds and some isolated severe weather from Florida to Louisiana with this low. High pressure will be over the Northern Rockies. The middle of the period there will see a very powerful storm system moving up the Eastern US with heavy snowfall and heavy rainfall possible. The period will finish with another low moving into the Pacific Northwest and out to the Northern Plains. This will bring more snowfall to the regions.
Green Energy Report for December 18, 2013:
Wave Energy: There will be large amounts of energy along the entire West Coast due to multiple storms moving through the region. The northern Gulf Coast will have lower amounts of energy today due to light winds still. The Southeast US will see slight to moderate amounts of energy and the Mid-Atlantic to the Northeast will have large amounts of energy.
Hydro Energy: There will be some long term energy along the Southeast coast of Maine near the low. We will also be looking at energy pushing into the Pacific Northwest. This will be a combination of short term and long term energy. The Northern Rockies will see long term energy.
Solar Energy: The majority of the Southern US from the Southwest to the Southeast including the Southern Plains and the Gulf Coast will have ample amounts of energy today.
Wind Energy: There will be moderate amounts of energy over the Pacific Northwest behind the storm system. There will also be ample amounts of energy over the Great Lakes and into the Northeast.
Weather and Your Wallet for Dallas TX:
High pressure will shift to the east of the area. This will allow for return flow to setup and start warming the region up nicely today under partly cloudy skies.
Dining: It will be a nice afternoon to enjoy lunch at the park.
Transportation: There should be no weather impacts on the roads or at the airports today.
Shopping: Today will be a nice day to get out and get some of that last minute holiday shopping done.
