It was yet another hot day away from the ocean and the usual jackpot area got another 90-degree day. South central NH into north central MA is the place to go if you want the hottest weather this summer and that would apply for most summers as well. The Nashua-Pepperell region typically gets the gold for the highest temperatures. Pepperell reached 91.5 today making this the 21st day of 90 or higher this season. Contrast that to Gloucester/Rockport where upper 70s kept it much more comfortable. The air was actually dry over the interior where it was the hottest while it was more humid along the coast where the breeze was blowing in from the ocean. Another slug of high cloudiness streamed up over southeastern New England this afternoon but this does not mean a surprise storm is brewing. A weak wave near Delmarva will transit out to sea and the cloud shield will thin and recede from west to east later this evening. Temperatures will settle down to the upper 60s most areas overnight.

It now appears that a delay in the arrival of a frontal boundary from the north means that showers and storms are unlikely in southern New England tomorrow. There will be some convection primarily across the northern mountains possibly down to the Lakes Region tomorrow afternoon and evening. The air will certainly be more humid especially in areas north and west of Boston that had the drier air today. Temperatures may be duplicated again tomorrow with the hottest spots nudging 90 northwest of Boston and the cooler locations in the upper 70s to just past 80 along the coast where the sea breeze is likely again. The wind will blow from the southeast to south at 6-12 mph with a late afternoon high tide just before 5:30pm. Sunshine may be filtered by a bit of high cloudiness or blotted out now and then by a passing puffy cloud. It will be humid without any rain and down to near 70 tomorrow night. On Friday, the risk of showers and thunderstorms increases closer to Boston but the main threat will be north and west of the city in the afternoon. With the expectation of cloudier conditions, it will be a bit cooler with highs in the lower to middle 80s. Later Friday night into Saturday morning, showers and storms may track northeastward into the region from PA, MD and NJ. Some of these may produce downpours. After that, it is possible that sunshine will break out during the day Saturday resulting in a volatile setup for an outbreak of some strong storms later in the afternoon and early evening. We’ll be monitoring parameters for that outbreak.

Looking ahead, it now appears that the cold frontal boundary may accelerate quickly enough so that the sky will be all cleared up just in time to view the peak of the Perseid Meteor Showers. Check the link for more details. There will still be some leftovers on Sunday night when it is clear. In between, Sunday should be a spectacular summer day with less humid conditions, a nice breeze and highs in the middle 80s. This great weather will last at least through Monday and Tuesday. There might be a brief shower or storm in a few spots a week from today.

We’re keeping an eye on the tropics and you can too by logging on to the National Hurricane Center.

Melissa Mack delivers her AccuWeather Forecast in the morning and I shall follow later in the day for the vacationing Todd Gutner.

Make it a great Thursday!
