Major Weather Impacts Discussion for April 19, 2013:

Day 1-3: Low pressure moving through Southeast Canada with the associated cold front will bring showers along the entire East Coast. Some thunderstorms are expected from the Gulf Coast into portions of the Southeast. A strong and cold area of high pressure is building in over Texas. This will bring temperatures to about 20-30 degrees below normal all the way into Texas and parts of the Gulf Coast. A nice day in store from the Rockies into the Southwest, while another frontal boundary brings showers to the Northwest. Day two high pressure will build in over the Great Lakes bringing a dry but cool day to the region, while the clipper system moves into the Northern Plains and Rockies bringing some snow and rain to the region. The period will finish with the storm system approaching the Great Lakes and the trailing cold front will bring showers and snow showers to the Plains and back into parts of the Rockies.

Day 4-7: The period will start with high pressure along the East Coast, while another storm system moves into the Great Lakes bringing rain and snow to the region. The trailing cold front will extend downwards to Oklahoma and Texas bringing showers to the region. Also a few snow showers will be possible over Colorado. Another cold and strong high pressure area will build into the Northern Plains. A new low will take shape over the Southwest. Day five the frontal boundary will extend from the Great Lakes to the Gulf Coast. Look for showers along this front with some strong thunderstorms near the Gulf Coast. High pressure will settle in over the Southern Plains. Day six a few showers will be along the East Coast. Otherwise most of the country will enjoy a tranquil day with no major impacts. The period will finish with high pressure over the East Coast and a new storm system developing in the Southwest.

Day 8-12: The period will start with high pressure over the East Coast and the storm system pushing into the Central Plains bringing some thunderstorms and possibly severe weather to the region. Showers will extend over the Northern Plains. Day nine a significant storm system will move into the Great Lakes with the associated frontal boundary extending southward to the Gulf Coast. Look for showers and some strong thunderstorms to develop along this frontal boundary. High pressure over the Plains will bring a nice day to the region. This will expand into the West Coast as well. Day ten the storm system will move into the Northeast with the cold front trailing behind all the way to the Gulf Coast. Expect another day of showers and thunderstorms from the Northeast to the Gulf Coast with some severe weather possible. The period will finish with a clipper system moving through the Northern Plains, while the rest of the country sees a tranquil day.

Long Range Outlook: The period will start with the clipper system moving north of the United States and high pressure dominating the weather from the East to the West. The middle of this period will have the cold front draping across the Great Lakes bringing showers and some thunderstorms to the area. The period will finish with a storm system moving up the East Coast, while high pressure builds in over the Plains and another storm system starts to take shape over the West Coast.

Ask The Weatherman for April 19, 2013:

Question: Where is the Jet Stream found?

Answer: The jet stream can be found at two different layers of the atmosphere and it all depends on the season. During the fall to early spring time period the jet stream is best found at about 20,000ft because colder air sinks so it´s lower. In the late spring to early fall the jet stream rises to about 30,000ft and this is due to the warming of the atmosphere all during the warmer time of the year.
