redOrbit Meteorologist Joshua Kelly
Big Story Weather from September 27: Severe weather hit the frontal boundary hard yesterday as there were reports of tornadoes in both Colorado and PA. The hail was the big story as many places got hit hard with hail in Colorado. In some place there were reports of hail in depth on the ground making it look like snow.
Weather Outlook for September 28: Stationary boundary will again extend from the Mid-Atlantic region all the way back southwestward into Texas. This region again will be the focus for some strong thunderstorms and possible severe weather. High pressure builds in over the Northern Plains which will bring a nice day to the region. A developing low in Mexico needs to be watched as it pushes out into the Gulf this weekend. Now let´s look at the weather for a few select cities:
Boston MA: P/C (storms) 59F | New Orleans LA: P/C(thunderstorms) 84F | Omaha NE: P/C 73F | Billings MT: P/C 76F | Seattle WA: P/C 77F
International Outlook: Tropical Storm Ewiniar will bring stronger winds and showers to the Tokyo area today, also a frontal boundary over the Korea´s will bring clouds and rain to the region. High pressure will bring nice conditions to Eastern Europe, while a low pressure moving through Spain will bring showers to the west. Low pressure over England will bring a gloomy day to the area. High pressure to the east of Australia will make for a nice day on the East Coast, however the frontal boundary will bring some clouds to the Central and Western parts of Australia.
Atlantic Basin: Tropical Storm Nadine gained strength and is now back up to 55kts and a pressure of 993mb. This storm will slowly drift back northward.
Eastern Pacific: Miriam is pretty much moving into the Baja today with winds around 35kts and a pressure of 1000mb, another area of concern has pushed off the coast of Mexico today and currently has winds of 25kts with a pressure of 1007mb.
Western Pacific: Jelawat continues to pack a punch with winds around 125kts and a pressure of 929mb. This storm is now moving east of Taiwan and looks to be a direct hit over Okinawa towards next week and then move into mainland Japan making a second landfall as a very strong Typhoon. Also Ewiniar continues tracking just east of Tokyo with winds around 45kts and a pressure of 989mb. Two new areas of interest are sitting to the southeast of Guam – both have winds around 15kts and a pressure of 1010mb.
ENSO Watch: Conditions are still favorable for the development of El-Nino within the next few weeks. A significant development that could be signs of El-Nino. The first is the ridge in the west is gaining strength forcing systems into Canada and then down through the plains which we have been seeing for some time now. The second is the development of Gulf Low´s near Texas. This is also a feature of El-Nino.

Major Weather Impacts Discussion for September 28, 2012:
Day 1-3: The frontal boundary and associated low pressure moving through the Southern Plains and Ohio River Valley and then towards the Northeast will be the big impact for the day with severe weather possible in these regions.
Day 4-7: The low pressure system will move into the Gulf of Mexico leading to some increasing winds and also enhanced rainfall from LA-AL and will drift slowly northward towards the MS/AL border. This feature should stay as a Gulf Low and not become tropical. Towards the Day 6 period the strong high pressure center will drop out of Canada and move towards the Plains. This feature will also develop a small pocket of moisture on the southwest side which may bring rain and a mix of precipitation to the Northern Plains.
Day 8-12: The low pressure system will move into the Great Lakes and bring an increase to moisture along with colder air. There is also the possibility of snowflakes in the Northern part of Michigan during this time period.
Day 13-15: The strong high pressure system will encompasses about 2/3 of the country from the Rockies eastward, while a weak trough will setup right along the Rockies and start making its way southward towards Texas.

Ask The Weatherman for September 27:
Question: What does it mean to have a warm core weather system?
Answer: In weather we have these neat features which are known as warm core weather systems. What they are is a weather feature that is warm at the surface all the way to 30,000ft in the sky. Some types of low pressure systems that are warm core are hurricanes and also sub-tropical high pressure systems such as the Bermuda Azores High.

Green Energy Weather Report for September 28:
Wave Energy: The biggest waves will be found along the coast of California again today as the tropical system finally begins to push on shore near the Baja. A second area that will begin to develop today will be in the Gulf of Mexico just to the east of Texas with our new low pressure system.
Solar Energy: The Northern Plains will be under high pressure which will lead to a great day of sunshine in the region, also look for the Pacific Northwest and portions of the Southwest to have a nice solar energy kind of day.
Wind Energy: No major areas that will see winds persist for long enough to be considered good.
Hydro-Energy: The frontal boundary extending over the Red River in Texas and also the Southern portion of the Mississippi River will lead to excellent water gathering days in both basins.
