Major Weather Impacts Discussion for April 18, 2013:
Day 1-3: Low pressure moving through Illinois today will bring showers and snow showers to the Lakes region. Look for the snow showers to extend back westward into the Northern Plains area as well. Snowfall amounts of 6 plus inches is very possible in this region. Showers and thunderstorms will also develop ahead of the cold front from Illinois to the Gulf Coast and parts of Eastern Texas. This region will see heavy rainfall along with the chance for severe weather with many tornadoes likely. The majority of the West Coast will enjoy a nice day. Day two the storm system will push into Southeast Canada and the associated cold front will extend all the way down to the Gulf Coast. Expect to see showers and thunderstorms along this front with the chance for another day of severe weather likely, especially around the Gulf Coast and Southeast. Strong and unseasonably cold high pressure will build over Texas bringing some places another frost and freeze potential. High pressure will be over the Great Lakes during this time, while another clipper system moves through the Northern Rockies with some light snow and rain.
Day 4-7: The period will start with high pressure over the Northeast, while the clipper system moves through the Northern Plains and into the Great Lakes. A new storm system will be developing in the Southwest along with another clipper system moving into the Northwest. By day five the storm system will move into the Northern Plains and a strong cold area of high pressure will build in behind it bringing more rain and snow to the Northern Plains. We are also expecting some thunderstorms and rain to develop over the Southern Plains with some severe weather possible. Day six the parent low will move into the Great Lakes bringing rain and snow to the region. A new low will begin to develop along the Gulf Coast with a strong and cold high pressure back over Texas setting the stage for possible severe weather. The period will finish with the low pressure finally pushing into the East Coast bringing rain to the region, while an upper level trough will push through the Northern Plains bringing another round of snowfall to the Northern Plains. High pressure will build in over the Rockies.
Day 8-12: The period will start with high pressure over the Plains and the upper level cold trough moving through the Midwest and Ohio River Valley. There could be some rain and snow associated with the trough. High pressure will be out West. Day nine a low pressure will be over Maine, while high pressure builds into the Ohio River Valley extending southward towards the Gulf Coast, and another area of high pressure pushes onshore over the West Coast. Day ten brings the upper level low over the Mid-Atlantic region with some showers possible. High pressure will build in over the Great Lakes and another clipper system will move through Canada. The gradient over the Plains will be strong and we could be looking at very strong winds from Texas to Minnesota. By day eleven the storm system will push towards the Great Lakes and a cold front will extend southward into Texas. This could be the site of the next severe weather outbreak. The period ends with a storm system moving through the Plains region bringing rain and some severe weather to the area.
Long Range Outlook: The long range will start with a storm system moving through the Ohio River Valley extending back towards Missouri with showers and thunderstorms along this boundary. The period will finish with two more storm systems moving across the Plains and into the Great Lakes.

Ask The Weatherman for April 18, 2013:
Question: What is an Easterly wave?
Answer: Great Question today!. An easterly wave has to do with the tropics. For this answer we will look at an area of convection that leaves the African coast and pushes out into the Atlantic Ocean. This area is defined as an easterly wave because it moves from east to west in the tropical region. Now, if this waves gets stronger, it can turn into a tropical system such as tropical storm or hurricane. Easterly waves are well known for their amounts of rainfall and stronger winds.
