Danny Heading Out to Sea...A "Cooler" Change on the Way...


Tropical Storm Danny continues to be rather weak and has increased its forward speed as it now heads north-northeast well off the East Coast. The storm is expected to pass by the Outer Banks of North Carolina early Saturday morning and then offshore of southern New England Saturday evening. It should move near the Canadian Maritimes on Sunday.

As for effects on the Mid-Atlantic coast, there won't be much in the way of rain or wind at all. The main problem will be a high risk of rip currents due to large ocean swells. Dangerous surf condiitions will continue into Saturday night.

In central Virginia, an upper low crossing the region has brought showers, but those will taper Saturday morning. Somewhat drier air will mean the sun will pop out, although with rather high moisture content in the atmosphere we could still see an isolated shower or thunderstorm around during the day. Then on Sunday, a cold front will approach from the west offering the possibilty of a few scattered afternoon thunderstorms. Behind this front, a signficant change is on the way, with afternoon temperatures in the 70s early next week. The front will actually linger over the southern Mid-Atlantic and Southeast. At this time, it appears a few ways of low pressure may move along the front, potentially bringing occasional rain chances, particularly late Monday into early Tuesday and then again Tuesday night into early Wednesday.
