Welcome Back!

It's welcome back time here at NE Weather Rants! I had big plans to write 3-4 blog posts a week over the summer. You can see how well that went. No matter, its a new month, a new school year and shit is about to pop off! Alright, that was a little too much excitement.

What better day to start blogging again than a rainy and muggy day? Honestly, we have nothing to complain about in the weather department here in the Northeast. We have enjoyed a BEAUTIFUL stretch of weather.  From August 19th - September 3rd, we had sunshine and temperatures in the 70-80 degree range for 15 of 16 days. With some real gorgeous days mixed in there as well. You couldn't have asked for a better and more comfortable stretch of weather to end the summer. So today and tomorrows rain shouldn't dampen your spirits too much.

As for that rain, most of the shower activity for today will begin to tamper off as the afternoon rolls along. You may have noticed that the air is much stickier today, you can thank our dearly departed friend Issac for that. After drenching the Gulf Coast last week, Issac moved into the Ohio River Valley and essentially spun himself out for the last 4 days. A strong cold front pushing south through the mid-west finally got whats left of Issac moving again, which is what we are dealing with over the next 18-24 hours. Tropical air, and tropical downpours. All without the ambiance of a tropical setting with fruity drinks. You can see from the QPF image below that most of the heavy rainfall will stay over Northern New England. Much of that heavy rainfall will occur very early tomorrow morning, which should make for a nice 1st back to school commute of the year. Expect heavy rainfall in the Boston area from 5-10AM with slow clearing and isolated downpours after that.

Leslie is a funny little storm. She is going to get caught in between strong High pressure over the central Atlantic and a somewhat inverted Northern Hemisphere jet stream to here west.

This will cause her to sit and spin in place just to the south of Bermuda for a few days, while intensifying to a category 2 storm. You can see that once she does get moving, she makes a close pass to New England, but not close enough for any real effects. Except of course for some pretty high surf. Take a look at this predicted wave height model for the East Coast as Leslie makes her pass on Sunday/Monday. Expect seas as high as 12 feet off shore with some coastal beach erosion likely all weekend.
