Big Story Weather Discussion for August 1:

Surface Map: Low pressure moving across the Great Lakes will bring showers and thunderstorms to the area. Showers and thunderstorms will also be possible along the cold front that extends back into the Plains. High pressure over the Mid-Mississippi River Valley will bring nice weather to the region. High pressure over the Northern Gulf will bring another day of showers and thunderstorms to the Gulf Coast region. High pressure over the Rockies will make for a nice but warm day across most of the region. There will be a few afternoon thunderstorms over Arizona and New Mexico and the West Coast will be dry and warm.

Severe Weather: There are three areas of concern for today. The first is over the Great Lakes and back into the Plains. This region will be dealing with heavy rains and damaging winds along with some hail as the main threats. The second area over the Southwest will also mostly be dealing with heavy rains and damaging winds. The third over the Northern Gulf Coast will be a heavy rain and damaging wind threat as well.

Tropical Weather: A wave moving northwest of Cuba will bring gusty winds and showers to the region.

Day five the high pressure will shift into the Ohio River Valley, while another frontal boundary pushes into the Northern Plains bringing showers and thunderstorms to the region. Day six the high pressure will push into the Mid-Atlantic, while low pressure slides into Minnesota bringing showers and thunderstorms to the region. The period will end with a frontal boundary over the Northeast bringing showers to the region and another frontal boundary will into the Central Plains bringing more showers and thunderstorms to the area.

A strong high pressure area will remain over the Great Lakes and the Northern Plains.

Long Range Outlook: The long range will start with low pressure developing near Maryland that will bring showers and thunderstorms to the region. The strong high pressure system will shift into the Ohio River Valley and a few thunderstorms begin to develop back over the Plains. The period will finish with a strong cold front advancing into the Northern Plains with showers and thunderstorms. Return flow over most of the East Coast will lead to very wet conditions and this will also be true for the Gulf Coast.

Ask The Weatherman for August 1, 2013:

Question: What is warm air advection?

Answer: Warm air advection is the process of taking warmer air and the wind blowing it towards a colder area. So if we look at two towns, Town A which is in the north, and town B which is in the south. The temps at Town A are 88F, while town B the temps are 92F, now in one hour the temps at Town A warmed to 92F, that means warm air advection moved into Town A from the south.

Solar Energy: There will be ample amounts of solar energy from the Mid-Atlantic to the Carolinas. We are also watching from the Western Dakotas to Western Texas. The majority of the Rockies will have good amounts of solar energy today along with most of the West Coast.

Wind Energy: The best wind energy today will be found over the Great Lakes behind the low pressure area and also over the Northeast behind another area of low pressure.

Hydro-Energy: There will be moderate amounts of energy from the Great Lakes to the Eastern Plains. There will also be smaller amounts of energy along the Gulf Coast and parts of the Southeast. A few places in the Northeast will see slight amounts of energy as well. A pocket of light energy will also be found over the Southwest.
