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

Big Story Weather from March 20: Yesterday’s biggest news was the arrival of Spring across the Northern Hemisphere,, but a good portion of the United States did not feel like it. A very cold air mass was in place from the Northern Plains southward into the Southeast United States where frost/freeze advisories where in effect. Also the Northeast saw snow showers again yesterday as the low finally began pushing away from the coast. The Northwest saw rain shows and high elevation snows from a passing frontal boundary.

Big Story Weather Discussion for March 21: High pressure will slide into the Great Lakes. Expect to see partly cloudy skies and cool weather with this high. These conditions will extend towards the Southeast. A new storm system will be taking shape over Texas and will bring showers over West Texas and a rain and snow mix to Northern Mississippi and moderate snowfall to Arkansas and Missouri where winter storm watches are in effect. Snow will expand into the Rockies as well. A few showers along the Northwest will be possible today as well.

Here is the weather for a few select cities:

Baltimore MD: Partly cloudy skies with a high near 35F. Look for overnight lows to fall to around 27F.

Memphis TN: Mostly cloudy with a period of rain/snow, changing to all snow for a period of time. Total snowfall accumulations could be around 3 inches. High temps will be around 38F and low temps will drop to around 30F.

Major Weather Impacts Discussion for March 21, 2013:

Day 1-3: A few morning snow showers will be possible over the Northeast, otherwise look for high pressure to bring nice weather from the Great Lakes southward into the Southeast. A new storm system will be developing over the Southern Plains; expect to see rain and snow with this system. This will move into Arkansas and Mississippi today. The southwest will enjoy a nice day today, while the northwest will still be dealing with some rain and snow. During the middle of the period the low pressure area will shift back to the west slightly over the Rockies. The period will finish with a powerful storm system moving through the Gulf Coast bringing an increased chance for severe weather. High pressure will be building in over the Northern Rockies.

Day 4-7: The period will begin with the major storm system moving up the East Coast; expect to see rain and snow in the region. High pressure will be building in over the Northern Plains. A new storm system will be pushing into the Baja during this time. The majority of the United States will be dealing with high pressure during the day five period. High pressure will shift into the Great Lakes, while wrap-around snow will be possible over the Northeast. The period will end with high pressure still over the Great Lakes, while a new storm system approaches the Northwest.

Day 8-12: The period will start with high pressure over the Hudson Bay extending southward into the Gulf Coast region, while the low pressure area moves into the Central Plains. During day nine the high pressure will rebuild into the Northern Plains forcing the low pressure area into the Southern Plains bringing showers and thunderstorms to the region. A new storm system will be pushing towards Southern California. High pressure will again be over the Great Lakes by day ten as a powerful storm system pushes into the Rockies. Looking at April 1, the storm system will push into the Central Plains bringing some heavy rain and also another round of heavy snowfall to the region. High pressure will push back into the Hudson Bay.

Long Range Outlook: A significant severe weather outbreak is possible to start this period from the Gulf Coast northward into Central Plains and Midwest. The powerful storm will push into the Great Lakes and bring heavy snow to the region, while it brings heavy rain to the East Coast. The period will finish with a powerful storm system along the East Coast and another storm system entering the West Coast.

Ask The Weatherman for March 21, 2013:

Question: Why are there always clouds in the tropics on satellite images?

Answer: The reason that you see extensive cloud cover and usually showers or thunderstorms in the tropics has to do with the pressure systems in this region. They are in an area of lower pressure meaning that the air wants to rise in this region, and when it rises it condenses into clouds and forms precipitation.
