Major Weather Impacts Discussion for September 24, 2013:

Day 1-3: High pressure over the Great Lakes will bring sunny skies to the region. This will also extend into the Northeast and the Mid-Atlantic. A low pressure area moving across the Gulf of Mexico will bring showers to the Gulf Coast and possible flooding to parts of Florida. High pressure over the Rockies will keep most of the region dry. This will expand into the Plains as well. A frontal boundary over the Pacific Northwest will bring showers to the larger cities in the region. Day two high pressure will dominate the Northeast, while low pressure moves out of the Gulf Coast and across the Southeast bringing more heavy rainfall to Florida. A strong low pressure area will push into the Plains bringing rain, winds and strong thunderstorms. The West Coast will remain dry. The period will end with a storm system bringing showers and thunderstorms over the Plains .

Day 4-7: The period will start with high pressure along both coasts. A storm system still over the Plains and a powerful storm will be moving into Alaska bringing heavy rains and even moderate snowfalls to the region. Day five high pressure will still dominate the East allowing for a cold front to develop from the Great Lakes to the Gulf Coast and back into Texas. Expect showers and thunderstorms along this front. A new storm system will be pushing into the Pacific Northwest. The period will end fairly tranquil across the United States except for a tropical wave near Puerto Rico.

Day 8-12: The period will begin with a trough over the Southeast bringing showers and thunderstorms to the region. Another trough will be moving into the Northern Plains with showers and thunderstorms. Day ten the trough will push into the Great Lakes and a strong area of cold high pressure will push into the Northern Plains. The period will end with a strong storm system moving up the Eastern US. There will be areas of heavy rainfall along with thunderstorms and perhaps even have a pocket of snowfall will develop over Southeast Canada and portions of the Great Lakes.

Long Range Outlook: The period will start with the strong low pressure area over the Northeast bringing rain and thunderstorms to the region. The cold air pocket on the west side may still bring another day of snow showers over Southeast Canada and portions of the Great Lakes. The middle of the period high pressure will dominate the East Coast, while a storm system moves into the Pacific Northwest bringing showers to the region. Another tropical wave should develop near Puerto Rico. The period will finish with a strong storm system moving through the Plains bringing showers and thunderstorms to the region.

Ask The Weatherman for September 24, 2013:

Question: What is off shore flow?

Answer: When you hear the meteorologist use the term off shore flow, what they mean is that the wind flow pattern is supporting a breeze that is blowing from the land to the water. This means that it’s heading off shore. This type of breeze is known as the land breeze and it takes place during the night time hours along coastal cities.
