By day ten the storm system along the East Coast will bring showers and thunderstorms to the major cities along the coast. High pressure will push into the Great Lakes. The storm system over the West will move into the Rockies bringing a few showers and thunderstorms to the region.

Ask The Weatherman for May 13, 2013:
Question: What are driving factors on a hurricanes path?
Answer: As we get closer to the Hurricane Season for the Atlantic Ocean we take a look at another interesting aspect. The path of hurricanes can be tricky. There are many things that can impact the track. Here is just one – the sub-tropical high pressure center. Wherever this located will force the tropical to move counter-clockwise around it. So once the tropical gets on the western side of the ridge it will usually make a sharp turn to the north.
