Greater Boston, North Shore and Metro West: Look all around you and signs of fall are here. Schools are gearing up to return to class next week, football teams have begun practices along with the cheerleaders, band and perhaps the track teams as well. Suddenly you begin to notice the days are growing shorter as the nights turn longer. As we approach the final weekend of August you start thinking about the change in schedule as we go from the more relaxing summer schedule with vacations, longer days and say goodbye to the warm weather as well. Or, do we?
We have just had a long stretch of warm and humid weather that has come to an end with the passage of a cold front during Wednesday. We can look forward to a couple of really nice days ahead which actually should last into the weekend. Warm temperatures but with much lower humidity translates into a more comfortable weather environment Thursday, Friday and at least through Saturday before the humidity and heat slowly inch back into our neighborhoods during Sunday. The outlook into next week is for uncomfortable humidity and above normal temperatures.
High pressure has eased into New England as the cold front moves well offshore. A much drier air mass has overspread the region and we are in for a few spectacular days of weather ahead. With mostly to partly sunny skies on Thursday and again Friday, high temperatures both days should hover around 80 degrees. Expect dry and cooler conditions with mainly clear skies Thursday night and again on Friday night with overnight lows in the upper 50s across the valleys to low 60s elsewhere. Winds stay light Thursday and Friday.
As the high moves offshore over the weekend it will begin a transition back to warmer and more humid conditions as winds turn southwesterly, but not before we squeeze in another real nice day on Saturday. The mercury should climb a few degrees higher and max out in the low 80s in the afternoon under a mainly sunny sky and light winds. A great beach day.
Saturday night will be milder than the previous few nights. Lows stay in the mid to upper 60s.
Then on Sunday you will begin to notice an increase in humidity along with temperatures climbing well into the 80s. Although a remote shower cannot be ruled out, overall it looks to be a splendid day. Temperatures at night may only fall to around 70, especially in and around Boston, perhaps the upper 60s elsewhere.
Early next week, just in time for the return to classes for many public school students, it appears summertime heat and humidity returns and stays around until at least mid week. Some of us may reach 90 or so on Monday and that scenario could be repeated on Tuesday as well. Skies stay fair and we generally remain in a dry spell through the next week or so. The overnights stay warm and somewhat uncomfortable with lows around 70.
Tropical Storm Erika may be sitting off the southeast US Coast by Tuesday and this will have to be watched. It is way too early to know if it impacts any coastal areas to our south but just keep an eye on updates over the weekend. On the flip side this system could get sheared apart in the upper levels and simply be a non issue.
