Major Weather Impacts Discussion for September 5, 2013:

Day 1-3: High pressure over the Northern Plains and Great Lakes will bring partly cloudy skies and very cool weather overnight with low temps in the 30’s for some. The onshore flow will bring an afternoon sea-breeze to the Gulf Coast and the Southeast allowing for thunderstorms to develop. High pressure over the Rockies will keep the region dry and warm. An area of low pressure will move through the Pacific Northwest bringing moderate rainfall to the region along with an increased chance of flooding. The southwest monsoon will bring a few afternoon showers to the region. Day two high pressure will slide into the Northeast, while a few afternoon thunderstorms will be possible over the Gulf Coast and Southeast along the sea-breeze fronts. Tropical storm conditions will continue for Puerto Rico. A strong low pressure area will continue to bring heavy rainfall to the Pacific Northwest which will be great help for all the dry conditions and reduce fire dangers in the region. The period will finish with low pressure moving into the Northern Plains bringing showers and thunderstorms to the region.

Day 4-7: The period will start with low pressure over the Northern Plains bringing showers to the region. High pressure will move into the Great Lakes. There will be moderate rains over Montana as well. The tropical storm will continue to move towards Bermuda. During the middle of the period the strong low pressure area will move into the Plains bringing some strong thunderstorms to the area. The period will end with high pressure along the East Coast, while showers and thunderstorms will be over the Gulf Coast. The strong low pressure will move into Canada and the cold front will extend into the Plains bringing another day of showers and thunderstorms to the region. The southwest monsoon will bring moderate rainfall to the Southwest. A strong low pressure will be moving into Alaska bringing showers and some higher elevation snows.

Day 8-12: The period will start with high pressure along the East Coast. Tropical moisture will be on the increase over the Gulf Coast. Another frontal boundary will move through the Northern Plains. By day nine a strong storm system will extend along the entire East Coast back into the Gulf Coast bringing showers and thunderstorms to the entire region. High pressure will slide into the Northern Plains. The period will end with a very strong high pressure area along the East Coast. Moderate rainfall will extend along the Gulf Coast and interact with a tropical surge as well. There will be another low moving into the Northern Rockies. Expect to see a very tight gradient over the Northern Plains which will lead to strong winds.

Long Range Outlook: The period will start with the strong high pressure area over the East Coast and the low pressure moving out of the Rockies into Canada. The winds will be strong again over the Northern Plains. Moderate return flow rain will be over the Southeast and Gulf Coast. The middle of the period will have the high pressure over the East Coast allowing for more return flow to setup over the Gulf Coast and Southeast. The low pressure over the Northern Rockies and Canada will extend a cold front through the Plains and will be the focus of showers and thunderstorms – some severe weather will be possible. The period will end with the high pressure still holding over the East Coast creating another day of return flow along the Gulf Coast and Southeast. A tropical feature will begin to push into the Baja bringing heavy rainfall to Southern Arizona and New Mexico along with Southern California.

Ask The Weatherman for September 5, 2013:

Question: Who defined the tornado scale?

Answer: The tornado scale was created after a tornado in North Dakota. At that time Dr. Fujita had the chance to go out and survey the damage and this lead to the creation of the Fujita Scale. In recent years a few changes have gone into the scale so the new scale is now known as the Enhanced-Fujita Scale.
