Jan 21, 13 Big Story Weather – January 21, 2013

Daily weather forecast and wrap-up provided by redOrbit meteorologist Joshua Kelly.

Big Story Weather from January 18-20: The biggest story from the weekend was the onset of the cold air that is pushing through the Northern Plains and making its way southeastward. Some locations in the Northern Plains have been seeing low temps in the negative 20 range along with wind chill values near negative 50F.

Weather Outlook for January 21: Low pressure moving through the Great Lakes today will bring Lake effect snows with snowfall amounts near six to ten inches for many places. High pressure moving into the Northern Plains will bring the onset of more Arctic air as temps will be heading to the negative area with wind chills near -45F or colder. High pressure over the Rockies will keep the west dry for another day. Below is the weather for a few select cities.

New York NY: Partly Cloudy/Evening Snow: 31F
Gulfport MS: Partly Cloudy: 63F
Omaha NE: Partly Cloudy: 15F
Billings MT: Partly Cloudy: 30
San Diego CA: Partly Cloudy: 61F

International Weather Outlook for January 21: Low pressure moving through Japan will bring cloudy skies with rain showers and mountain snows to the region. High pressure over Eastern China will keep the region partly cloudy and this will extend into the Koreas. High pressure over the Tibetan Plateau will keep the monsoonal trough well offshore today. Low pressure moving towards Spain will bring increased clouds to Western Europe. A frontal boundary moving through the tip of South America will bring showers to the region. High pressure will slowly push towards Western Australia, while a frontal boundary impacts Eastern Australia with showers and thunderstorms and then a tropical cyclone will bring showers to the Northern Regions. Here is the forecast for a few select international cities.

Tokyo Japan: Cloudy with Rain and a low near 4C
Hong Kong China: Partly Cloudy with a low near 18C
Singapore: Partly Cloudy with a low near 20C

Major Weather Impacts Discussion for January 21, 2013:

Day 1-3 A frontal boundary moving through the Great Lakes is going to bring some very heavy snowfall to regions downwind of the lakes such as Buffalo NY. High pressure over the Northern Plains will start to bring very frigid air to the region today as it slowly pushes towards the Southeast. High pressure over the Rockies will keep the region from the Rockies to the West Coast nice today. The middle of the period will have most of the United States under high pressure and cold air. A frontal boundary will begin to push towards the West Coast. The period will end with the strong high pressure center moving into the Great Lakes while the frontal boundary will begin to push onshore over the West.

Day 4-7: The period will begin with high pressure along the East Coast and a weak frontal boundary moving through the Northern Plains which will bring some light snow to the region as another high pressure area builds in over the West. The middle of the period will have the frontal boundary pushing towards the East Coast and a trailing cold front will move the through the Gulf Coast bringing some thunderstorms to the region while it should bring a cold rain and light snow to the north. High pressure will be over the Northern Plains. The period will end with a high pressure over the East Coast, while another frontal boundary develops over the Northern and Southern Plains.

Day 8-12: The period will begin with high pressure over the East Coast and a frontal boundary over the Gulf Coast region with the associated low pressure back in the Southwest. Another area of high pressure will be over the Northern Plains. High pressure will be sitting over the West Coast. By day 10 there will be a significant storm system sitting in the Southwest with the associated frontal boundaries in the Plains and also the Gulf Coast region, expect to see some heavy rains and snows for the north and also some strong thunderstorms through the Gulf Coast region. The end of the period will be marked with a very powerful winter storm for the Northern Plains and into the Great Lakes, while a potential severe weather event sets up for the Gulf Coast region into the Southeast.

Day 13-15: The period will begin with the strong low pressure system moving into the Northeast creating a large mess of snow and rain for the region. High pressure will be along the West Coast, while a piece of energy moves over the top of the ridge into the Pacific Northwest. The second day of the period will have the frontal boundary to begin pushing off the East Coast, while the piece of energy begins to slide into the Northern Plains bringing a swath of snow to the region. The middle of the period will have high pressure over a majority of the US bringing quiet conditions to the region. The period will end with multiple areas of low pressure moving across the region again bringing some very unsettled weather to the area. During this time we will also need to watch the development of the split flow Jetstream from the Pacific Northwest and through the Southern tier of the United States that could help set the stage for this active weather pattern.

Ask The Weatherman for January 21, 2013:

Question: Why does it get warm when the high pressure passes east of us?

Answer: Great weather dynamics question. Due to dynamics of a high pressure, the winds on the back side or the west side of a high are from the South to Southwest, this brings warm air from the south to the north. This transportation of warmer air is why you will see it get really warm on the backside. Sometimes on the weather map in the winter you will see warmer temps in the Northern Plains than you will see in the Southeast at the same time and that is because of the location of the high pressure.

Green Energy Weather Report for January 21, 2013:

Wave Energy: The Pacific Northwest and the entire West Coast will see an increase in wave action today making it a great spot for wave energy. The second location will be along the Northeast as the next frontal boundary starts to make its way into the region.

Solar Energy: The West Coast is under high pressure and has plenty of solar power potential again today. The Southern Plains expanding into the Gulf Coast will be another great place for solar energy today.

Wind Energy: The Northern Plains into the Great Lakes will be the best place for wind power today.

Hydro-Energy: The Great Lakes will have plenty of snowfall today which will add to the regions base and also create a nice long term hydro energy build up.
