Weather: My Bonnie's No Longer Over the Ocean?

By Greg Lawson
Staff Meteorologist

What's Bonnie's next move? Last night, she made landfall in North Carolina just north of Wilmington and Cape Fear. Now over land, far from her primary energy source, she should begin to weaken. She is already showing signs of slowing down in her drift speed, that is the speed at which she is moving north, not the rotational speed of her winds. This is very bad because it could lead to severe flooding for communities between Cape Fear and the Chesapeake Bay. Also, it means that Massachusetts won't feel her effects until later than originally thought - now probably not until late Friday night. Meanwhile there are heavy surf advisories all about, including here in Boston. Increased coastal activity is still thought to be as serious as it will get around here.

As Bonnie collides with the cold front sweeping through New England, the front should become almost stationary. There appears to be another weak cold front following the current one down from Canada. What this means is that there is still a good chance of rain throughout the afternoon today, and a slight chance of continued activity through the night on into Friday. Things will clear Friday afternoon as some residual cloudiness and high temperatures bring us back to our normal balmy Boston weather.

Today: Good chance for showers & thunderstorms through the afternoon. Moderate southwesterly winds. High 81F (27C).

Tonight: Partly cloudy with scattered showers possible. Low 70F (21C).

Friday: Continued chances for scattered showers through the afternoon. Expect a tame evening. High 87F (30C).
