Big Story Weather from July 10: The heat hit the Southwest and Southern Plains again yesterday, while the cool weather stayed over the Pacific Northwest. High pressure brought nice weather to the Northern Plains. Severe weather yesterday hit really hard around the Ohio River Valley with well over 400 damaging wind reports coming from this region. The highest wind gusts occurred through most of Ohio in the range of 80-87mph. The largest hail occurred in a super-cell over South Dakota at 2.5 inches. There was also a landspout in Colorado.

Big Story Weather Discussion for July 11: The cold front will be placed along the East Coast and trailing back into the Gulf Coast today. This will set the stage for heavy rains and thunderstorms over. High pressure will slide into the Great Lakes bringing a nice day to the region after all the severe weather yesterday. High pressure will also keep the Northern Plains dry today. An area of low pressure will try to bring a few rain showers to parts of Arizona, however the heat will still be on. This will extend into the Southern Plains as well. The West Coast will be dry and nice today.

Severe Weather: The biggest threat for severe weather today will be from the Northeast back into the Gulf Coast along the frontal boundary. The primary threat will be wind damage and large hail, however an isolated tornado cannot be ruled out, especially in the Northeast. There will also be a few isolated severe storms over the Southwest. The main threat here will be damaging winds and large hail.

Tropical Weather:
This morning we are watching two waves. The first is just to the east of Florida and slowly moving over the area today. This area does have the potential for some development when it hits the Gulf. The second is the remains of the tropical as it continues to move towards Cuba today with heavy rains and strong winds.

Here is the weather for a few select cities:

Baltimore MD: Partly cloudy with scattered thunderstorms and a high near 82F. Overnight lows will be around 70F. Total rainfall will be around 0.65 inches.

Low pressure moving towards Iceland will bring showers to the area.

Western Pacific: Typhoon Soulik has winds around 95kts and pressure near 952mb as it continues to move towards Taiwan and also Eastern China for a potential landfall. Low pressure moving across Northern Japan will bring showers to the region. A tropical low pressure southeast of Chichi-Jima will bring strong winds and heavy rain to the region.

Indian Ocean: The monsoonal trough will be very strong again today providing plenty of rainfall to the region as the flooding potential will be high.

Ask The Weatherman for July 11, 2013:

Question: What are the types of lightning?

Answer: The first type is called (C-C) cloud to cloud, meaning the electric charge travels from one cloud to the other. The second is (C-G) cloud to ground, meaning the charge hits the ground somewhere. Thirdly is the (C-A) cloud to air, meaning that it will leave a cloud and transfer to the clear air. Lastly is the (IC) as in cloud, meaning that you will see the lightning bolt travel through the cloud but stay in the same cloud.
