Big Story Weather – May 6, 2013
Daily weather forecast and wrap-up provided by redOrbit meteorologist Joshua Kelly.
Big Story Weather from May 4-5: This past weekend was very active over most of the Southeast with enormous amounts of rainfall and flooding from Alabama, Georgia and into the Carolinas. The other big story was out West were the wild fires have been burning through parts of California. An area of showers today in that region will provide some much needed relief.
Big Story Weather Discussion for May 6: That pesky high pressure over the Western Atlantic will only shift a small amount which will allow the storm system to move into the Carolinas. The Southeast will be dealing with another day of heavy rain. Expect flooding to be a key issue in this region again today. High pressure over the Northern Plains will bring nice weather to the region. A new low pressure area developing over the Southwest will bring some much needed rain to the Southwest including parts of California where wild fires have been burning.
Here is the weather for a few select cities:
New York NY: Partly cloudy today and cool with a high near 57F. Overnight lows will fall to around 45F.
Atlanta GA: Mostly cloudy with showers by this evening. High temps will be around 59F and overnight lows will drop to around 46F. Total rainfall amounts will be near 0.65 inches.

May 6, 2013 Storm Tracker Update:
Atlantic Basin: Low pressure moving over Central Russia will bring a few snow showers to the region. Another area of low pressure moving into Western Europe will bring showers to the region, along with increasing winds and seas. Low pressure moving over the Southeast United States will bring another day of flooding rain to the region.
Eastern Pacific: A weak area of low pressure moving towards the Southwest will bring showers to the region. Light rainfall totals are expected but it will help with the fire conditions out West. A second area of low pressure moving over the Gulf of Alaska will bring increased winds and seas to the region along with some snow for Southern Alaska.
Western Pacific: Low pressure moving towards the date line will bring some showers towards Midway Island. Another area of low pressure moving over Eastern Japan will bring showers to the region. A third area of low pressure moving over Eastern China will bring showers and thunderstorms to the area. One area to the south of Guam is still being watched for possible tropical development over the next few days. At this time there is only a slight chance.
Indian Ocean: Two regions of low pressure have developed south of India. These two areas are being watched for potential tropical development and are moving slowly towards the west along the monsoonal trough.
Southern Hemisphere: Multiple areas of low pressure moving through this basin. One area of low pressure is impacting the tip of South America with showers and colder weather. A second significant one is moving south of Africa, however it is bringing seas well over 12ft to the region creating a marine hazard to shipping. A third area of low pressure with impacts is located over Southwest Australia bringing showers to Perth.

Major Weather Impacts Discussion for May 6, 2013:
Day 1-3: A strong upper level low and surface low will again impact the Southeast and parts of the Mid-Atlantic with moderate rainfall and flooding conditions. High pressure over the Northern Plains will bring nice weather to the region. A nice day in store for the Gulf Coast as well. A new developing low pressure area over the Southwest will bring showers to the region, while the Pacific Northwest enjoys a nice day. Day two will have the low pressure over the Southeast and Mid-Atlantic bringing more moderate rainfall to the region, while a second low pressure area moves into New Mexico bringing showers to the Southwest. The period will finish with low pressure over the Mid-Atlantic spreading into the Northeast and the other low moving into Texas bringing showers to the region.
Day 4-7 The period will start with the low pressure area over the Northeast. The cold front will extend back to the Southwest where it will merge with the warm front of the system in Texas. This region along the frontal boundary will have rain showers and a few thunderstorms especially in the South. By day five the low pressure area over Maine with the frontal boundary extending back into the Gulf Coast along with the new low over Texas will set the stage for heavy rain from Texas and the Gulf Coast all the way northward into the Northeast. By day six a third low pressure area will move into the Great Lakes. This low pressure will absorb the Northeast low and attach to the Southern Low creating a wide area of showers and thunderstorms from the Great Lakes into the Northeast and southward towards the Gulf Coast and parts of the Southern Plains. A strong area of high pressure will begin to move into the Northern Plains and the West will remain dry. The period will finish with the low pressure area and cold front along the East Coast. High pressure will build into the Mississippi River Valley and another storm system will push into the Northwest.
Day 8-12: The period will start with high pressure over the Southeast keeping the East Coast dry. A clipper system will move through the Northern Rockies and Plains but should remain fairly dry due to lack of Gulf moisture. By day nine high pressure will push into the Mid-Atlantic allowing for a little more moisture to work northward along the clipper system bringing showers to the Northern Rockies and Plains region. By day ten the high pressure along the East Coast will keep the region dry, while return flow sets up over the Gulf Coast and Southern Plains bringing a few showers and thunderstorms to the area. A storm system moving through the Northern Rockies will bring showers and thunderstorms to the region. By day eleven the storm system will move into the Northern Plains and Great Lakes. The period will finish with the storm system bringing showers and thunderstorms from the Great Lakes towards the Gulf Coast.
Long Range Outlook: The period will start with the low pressure over the Northeast extending back towards the Southern Plains with plenty of rainfall along the boundary. Another weaker storm system will push into the Northwest during this time as well. The middle of the period will have a stationary boundary over parts of the East, while high pressure will be over the Great Lakes and another storm system will push into the Plains. The period will finish with a strong cold front going through the Northern Plains with some severe weather possible for the region.

Ask The Weatherman for May 26, 2013:
Question: What is the definition of an Air Mass?
Answer: When it comes to weather, air masses are one of the most important features that we have. Air masses are responsible for the constant change in temperatures from going very hot to very cold, as we have tropical air masses along with polar and arctic air masses. All of these bring different types of weather with them.

Green Energy Weather Report for May 6, 2013:
Wave Energy: The best places for wave energy today will be from the Mid-Atlantic into the Southeast ahead of the cold front. The second region of moderate wave energy will be over the Southwest along another frontal system. Lower amounts of energy will be found over the Northwest and also the Northeast and the Gulf Coast.
Solar Energy: Solar energy will be strong over the Northeast and also in Florida back over most of the Gulf Coast into the Southern Plains. High pressure over the Northern Plains will make this another good region for solar energy today. The Rockies and the Pacific Northwest will also have moderate days of solar energy.
Wind Energy: The best place for today’s wind energy will be over the Southeast and through parts of West Virginia behind the frontal boundary and the upper level low.
Hydro-Energy: There will be plenty of hydro energy spreading from the Southeast into the Mid-Atlantic as rainfall rates will be around 1-3 inches for many places in this region. A second place of good hydro energy will be over the Southwest with some places getting near 0.50 inches of rainfall.
