Forecast discussion: We have had arguably the best weather in the entire country the last few days in Southern New England. However, as we move towards the end of the week, a low pressure system to our west and a high pressure system over Canada will bring some cooler temperatures into early next week.
Right now, the delightful weather is due to a high pressure ridge. But, to our west, is a low pressure system bringing a line of showers into New York and Pennsylvania. To our south, we have a weak disturbance will clip Cape Cod. Now, the high pressure ridge will actually protect Boston from both sides. But, I would not be surprised if a sprinkle or light shower does form over eastern Massachusetts. The weak disturbance to our south will bring scattered showers to the outer Cape throughout Thursday.
Now, thanks to an upper level blocking pattern, we will not see any heavy rainfall or lengthy period of shower activity as we move into the weekend. But, the western system will continue to give us cloudy skies and the risk for some showers on Friday, especially during the late morning and afternoon. By Saturday, that same ridge will grow stronger, as the high’s center moves south, and into New England.
However, you will notice as we head through the weekend that temperatures seem a little chilly for this time of the year. Yes, high temperatures may only reach the lower 70’s through the weekend. Our temperatures slowly increase as the high moves out into the Atlantic. This is due to the winds turning to the southwest, allowing for warmer air to be brought north. At this time, the high will dominate our weather right into the middle of next week.
Finally, the tropics are beginning to become slightly active. As of today, an organized area of thunderstorms several hundred miles east of the Windward Islands is becoming better organized. At this time, there is a 50% chance this system will become a tropical depression within the next 48 hours. There is a 60% chance it becomes a tropical within 5 days. Right now, the American model pushes it through eastern Cuba before turning northwest, towards western Florida. I will continue to keep you updated tomorrow night.
