After another exquisite weekend made us all happy, the week ahead will not disappoint either unless you want steamier weather. There are still no signals that any heat waves are on the way for the rest of this month. There hasn’t been a day up to 90 degrees or higher since July 20. Last year, there were 2 August days over 90. Contrast that with August 2002 when we were in the beginning stages of one of the longest heat waves on record in Boston from the 11th through the 18th. Stats show that heat waves become less likely from late August into September but there can be a stray day or 2 of hot weather from time to time. Recently in 2010, the last 3 days of August and the first 2 days of September were really hot at 94, 92, 96, 94 and 95 respectively! Once In A Blue Moon, September can be extremely hot as in 1983 when there were several days over 90 including 3 record highs. The latest one on September 20 was 97 degrees! WOW! So just in case, don’t remove the air conditioners just yet!

A couple weak features are having minor impact on our weather this morning. One weak upper level disturbance traveled across northern New England overnight. Its trail of clouds sank southeastward into southern New England early this morning. It interfered with meteor watchers after midnight up north. The Perseid Meteor Shower is in the peak stage and will put on a decent show but the clouds will be increasing again to probably spoil the show. I saw 5 bright meteors or “shooting stars” on my way into work after 2 am today. Did you see any or get photos? Please share at www.cbsboston.com/connect.  The second feature is cranking out a broken string of showers from Long Island to Block Island and it may briefly skim over Martha’s Vineyard to Nantucket. Both features will exit the region later this morning so much of the region will become sunnier from north to south during the morning followed by a few clouds developing this afternoon. The wind will be west to southwesterly at 10-15 mph with highs near 82 many areas except a bit cooler at a few south-facing coastal locations. It will turn out to be another fine beach and boating day with a high tide at 3:45 pm. The ocean cooled off a bit near the coastline of east-facing beaches yesterday due to the brisk offshore wind.  The air will still be dry but not quite as crisp as yesterday as the dewpoints creep up to 56-60 degrees.

Looking forward, there will be only one showery and humid day this week and that one is tomorrow. Expect scattered showers and some thunderstorms anytime during the day but the activity should be most widespread in the afternoon and evening. It will be noticeably more humid with high temperatures near or slightly over 80. A more important upper level trough of low pressure and frontal boundary will progress eastward and move offshore tomorrow night. Following the frontal passage, the wind will freshen to 12-28 mph from the west-northwest Wednesday morning then decrease later in the afternoon. Residual instability will produce a cloud-dotted sky blotting out the sun from time to time and releasing a few spotty sprinkles and showers over the northern mountains.  A mass of cooler polar air will rush into the region as a large sprawling high pressure system takes its sweet time building eastward from the Lower Great Lakes and Midwest into the Northeast. It will provide a bright sunshiny sky from Thursday through Sunday. There could be a bit of high thin feathery cloudiness blossoming up over the region later in the weekend but no rain is currently foreseen with a protective ridge of high pressure over the region. Overnight lows will drop into the upper 40s to middle 50s except lower to middle 60s in the urban centers with daytime highs starting near 76 on Wednesday then inching a degree or 2 higher in each succeeding day. Light wind after Wednesday will enable a daily onshore breeze to form at the coast and that will make it a bit cooler at the beaches.

Todd Gutner returns from vacation and posts his blog early this evening and I shall return early tomorrow morning.

Make it a great day!
