Low pressure to the east of South America will bring a frontal boundary to the eastern shores of the region with showers and thunderstorms. Low pressure over Northwest Australia will bring showers and thunderstorms to the region. A strong area of low pressure is moving towards the Northeast portion of Australia.

Major Weather Impacts Discussion for January 18, 2013:

Day 1-3 A frontal boundary moving through the Great Lakes will bring some moderate snowfall to the region and this will spread into the Northeast overnight. High pressure over the Tennessee River Valley will bring a nice day to the Southeast and Gulf Coast region. High pressure over the Rockies will bring nice weather from the Rockies westward to the West Coast. The middle of this period will be dominated by high pressure over the majority of the country except for the Great Lakes and Northeast where the chance is there to see some moderate snowfall moving over the lakes. The period will end with a very strong high pressure center moving into the Northern Plains.

Day 4-7: The period will begin with high pressure dominating the majority of the country. The middle of the period will still have high pressure dominating the majority of the country, while a frontal boundary will be moving in towards the West Coast. The period will end with high pressure along the East Coast and a weak frontal boundary moving through the Northern Plains while high pressure rebuilds in over the West Coast.

Day 8-12: The period will begin with high pressure over the Eastern Seaboard while a stronger frontal system begins to move through the Great Lakes bringing snow to the region along with some showers to the southern boundary. High pressure will be in control of the weather over the west bringing a very nice pattern to the area. Towards day 10 look for the storm system to push into the Northeast as well as the frontal boundary extending down towards the Gulf Coast which will bring showers and thunderstorms to the south, while it will bring snow to the Northeast. High pressure will build in over the Northern Plains. A weak frontal boundary will be approaching the Pacific Northwest. The period will end with a strong frontal boundary system moving exiting the Northeast, while high pressure begins to build in over the Plains region. Another piece of energy will begin to develop over the Southwest.

Day 13-15: The period will begin with high pressure over the East Coast extending back into the Great Lakes, while a low pressure system will be moving into the Colorado Rockies which will spread snow and rain across the Rockies and the Southwest. By Day 14 the frontal system will push southward into the Southwest bringing moderate rains and snows to the region. High pressure will be along both coasts. The period will end with a very powerful storm system moving through the Great Lakes extending to the Gulf Coast as heavy rains and the potential for some severe weather will occur in the Gulf Coast region, while heavy rain will spread northward into the Tennessee River Valley and heavy snow will likely develop over the Great Lakes and spread into the Northeast. The big storm system will push up the East Coast possibly leading the way for a big Nor´Easter to make its way up the coast during this time period.

Ask The Weatherman for January 18, 2013:

Question: Why does the weather get cold when high pressure starts to impact an area?

Answer: Today´s Facebook question is an excellent one. The reason it gets so much cooler or colder when a high pressure moves through is because of the air flow around the high. The winds blow from the north on the right side of the high which means the air is coming from the North Pole and that is why it gets colder. Now if we look at the summer time, the air actually is still cool but not as cold as during the winter months. Also if we look at the Sub-tropical high pressure system that forms over the Atlantic Ocean, when this one moves into the region it gets warm and that is because we are on the backside of the high where the winds are from the south which brings warmer air in.

Green Energy Weather Report for January 18, 2013:

Wave Energy: The West Coast will have some moderate wave action in the area with a better chance towards Southern California as a storm system is moving towards the region. The Northern Gulf of Mexico will be another moderate area for wave energy today and moving into the Southeast.

Solar Energy: Locations throughout the Southern Plains will have good solar energy today as high pressure is over the area. Also the Southwest will have a good portion of solar energy and this will spread into the West.

Wind Energy: The three places of concern will be in the Southern portion of California along with a moderate area of winds in the Gulf Coast region and another in the Northern Plains behind the frontal boundary all of these places will generate moderate winds today.

Hydro-Energy: The Great Lakes will be the highlight of hydro energy for today and most of it will be long term hydro energy in the form of snow.

January 18 Weather and Your Wallet (Minneapolis MN):

Dining: Periods of light snow and colder temps will make it more attractive to take lunch to work today or enjoy the indoor eateries.

Transportation: The periods of light snow this morning will lead to some small commute issues, just make sure to give yourself some space between the car in front of you.

Shopping: Not a major impact day on shopping other than the snow this morning which may slow the drive into the mall. By this afternoon just a jacket will be needed.

Electricity: Today will be a fairly strong day for electricity needs especially during the overnight hours when we could be looking at 36HDD´s through the overnight hours will be the highest demand time period.

Yard Work: No big issues expected, just take it easy this morning if you have plans to work in the yard moving the new snow off the sidewalks.

Construction: The light snow this morning will create some slowdown in the road work arena, however by later this afternoon conditions should begin to improve and then it will become jacket and glove weather for the rest of the day.

Outdoor Venues: If you need to take the dog for a walk, this morning would be a nice time for it.
