Big Story Weather from August 28:

The heat impacted large areas of the Plains again yesterday with temps soaring over 100F and heat index values near 110. Severe weather was limited, however there were reports of hail around 1.75 inches in South Dakota along with wind gusts near 70-80mph in South Dakota, North Dakota, and Utah.

Big Story Weather Discussion for August 29:

Surface Map: High pressure over Eastern Texas will bring extensive heat to the region with temps in the 100’s. This warm air will expand northward into the Northern Plains as well. Many places will see heat index values over 110 so take it easy in these regions. A cold front over the Great Lakes will finally start to push eastward towards the East Coast later today. High pressure over the Rockies will keep the region dry and warm with a high fire hazard as well. Low pressure over the Baja will bring afternoon showers to the regions of Arizona and New Mexico. Tropical Storm Juliette will continue to move up the Western coast of Mexico.

Severe Weather: There will be three areas of concern today. The first will be along the frontal boundary over the Midwest where this region will see large hail and damaging winds. Thunderstorms over Arizona and New Mexico will provide heavy rainfall and strong winds. A third area over the Southeast Coast will bring heavy rain and strong winds to the region.

Tropical Weather: An easterly wave pushing off the west coast of Africa will have to be watched for possible tropical development over the next few days.

Select City Forecast:

Buffalo NY: Partly cloudy and cool again today with high temps around 74F and lows near 60F.

Mobile AL: Partly cloudy and warm with high temps around 91F and lows near 75F.

Sioux City IA: Partly cloudy with afternoon thunderstorms as high temps rise to around 90F and lows near 64F. Total rainfall will be around 0.25 inches.

August 29, 2013 Storm Tracker Update:

Eastern Pacific Ocean: Tropical Storm Juliette will continue a northward track towards the Baja with winds around 45kts and pressure near 999mb. The storm will slowly begin to weaken as it moves over colder waters. Low pressure moving through Alaska will continue to bring more showers to the region. Low pressure moving through Central Canada will bring showers to the region.

Atlantic Ocean: Low pressure moving through Eastern Canada will bring showers to the region. Low pressure moving towards Northern Europe will bring showers to the region. Two tropical waves along the coast of Africa will have to be watched for possible tropical development.

Western Pacific: Tropical Storm Kong-Rey continues to move north-westward away from Taiwan with winds around 50kts and pressure near 985mb. The storm is forecasted to maintain tropical storm strength as it pushes towards Japan. Low pressure moving over Western Japan will bring showers and thunderstorms to the region. Another tropical wave to the northwest of Wake Island will also need to be watched for possible tropical development.

Indian Ocean: The Southwest monsoon will not be as active today allowing for less rainfall coverage. A strong wave moving over the Indian Ocean will need to be watched for possible tropical development.

Southern Hemisphere: Multiple areas of low pressure moving through the basin with impacts being felt over Southern Argentina with showers and snow showers. A second wave moving southeast of South Africa will bring gusty winds to the region. A third area of low pressure moving over Southern Australia will bring showers to the region.

Major Weather Impacts Discussion for August 29, 2013:

Day 1-3: High pressure over Eastern Texas will bring warm and dry weather to the region. This will extend into the Southeast and Gulf Coast as well. The heat will be in place over the Plains with many places seeing high temps over 100F and heat index values reaching 110-115. The Northeast will be cool again today, while a frontal boundary over the Midwest will bring showers and thunderstorms to the region. High pressure over the Rockies will bring warm and dry weather to the West. The period will finish with a frontal boundary from the Northeast to the Gulf Coast bringing showers and thunderstorms to the region. A second front will be pushing into the Northern Plains. The southwest monsoonal rains will be on the increase again during this time.

Day 4-7: The period will start with a boundary along the Southeast and Gulf Coast bringing showers and thunderstorms to the region. Another frontal boundary will be over the Plains and the Great Lakes bringing showers to the region. Day five a storm system will be moving through the Great Lakes and the Gulf Coast bringing heavy rainfall and thunderstorms to the region. The West will mostly be dry along with a very powerful storm hitting Southern Alaska. The period will finish with a frontal boundary extending from the Mid-Atlantic to the Gulf Coast. Expect to see showers and thunderstorms along this boundary. High pressure will build in over the Great Lakes and the Ohio River Valley bringing cooler air to the region.

Day 8-12: The period will start with a storm system moving through the Eastern Lakes and the Northeast. High pressure will dominate the weather over the Northern Plains and also into the West Coast. Day ten a strong storm system will push into the Northern Plains and bring heavy rainfall along with severe weather. Day eleven the storm system will move into the Great Lakes, while return flow sets up over the Gulf Coast bringing showers and thunderstorms to the region. The West will be dry and warm again. The period will finish with showers and thunderstorms along the Gulf Coast and Southeast, while the majority of the country will be dry and warm in the West and cool in the East.

Long Range Outlook: The period will start with a very strong storm system moving into Southern Alaska bringing showers and snow showers to the region. Return flow will be over the Gulf Coast and Southeast bringing showers and thunderstorms to the region. The middle of the period will have high pressure over the Northeast, return flow and showers over the Southeast and Gulf Coast, and another strong storm system moving out of Montana and the Northern Plains bringing severe weather along with very cold rain on the back side. Southern Alaska will have another powerful low pressure moving into the region which will lead to more heavy rainfall and possible higher elevation snows. The period will end with the potential of seeing a large severe weather outbreak over the Plains from North Dakota to Oklahoma along a very strong frontal boundary.

Ask The Weatherman for August 29, 2013:

Question: What is defined as the cold cycle of the climate?

Answer: During the cold cycle of the climate, we start to see the ice sheets over the poles expand in coverage. We also start to notice sea temperatures beginning to drop. Then air temperatures will follow behind that. This will then in return alter weather patterns supporting more strong winter storms.
