Two consecutive days of pummeling by nasty boomers is all we can stand. Some of the cells released torrential rains producing some flash flooding while others dropped some hail and strong winds while others bypassed some communities completely. Check out these rainfall totals and local storm reports compiled by the National Weather Service. Lighter showers lingered into last night but all of that action has now shifted offshore so we say good riddance. Boston’s rainfall of the past 24 hours amounted to 0.65″ boosting the monthly total to 9.49″! That was sufficient to push the city into 4th place for the wettest June ever after starting out in 6th place Monday morning and rising to 5th place by Monday night.
High pressure is now beginning to build in from the Great Lakes and southern Canada. It will control our climate for the next several days as it treks southeastward and takes up residence offshore in a prime position to become the so-called Bermuda heat pumper. Initially, this system will force pleasantly mild and dry weather into the Northeast with the next couple nights cooling off to the middle 40s to middle 50s. Eventually, after arriving at its destination, the pumper will propel warmer and warmer air into the Northeast with higher humidity streaming in over the weekend into next week. Each successive day should be a few degrees higher starting with 75 today, 78 tomorrow, 82 Friday, 85 Saturday, 87 Sunday and nudging or exceeding 90 the first half of next week. All beaches will be cooler than those numbers especially south-facing coastal areas later Friday well into next week due to the prevailing south-southwesterly wind which may become brisk at times. On Cape Cod, the north-northeasterly wind will be especially breezy through midday today with less wind tomorrow.
Any streamers of wispy clouds and patches of low clouds will disappear this morning to be replaced by some small puffy-like “fair-weather” clouds popping up and providing some sky decoration this afternoon. The clear sky tonight will show off some moonlight from the waxing gibbous Strawberry Moon that will be exactly full at 7:32 am this Sunday. It is a so-called Supermoon that will enhance the overnight high tides especially this weekend into early next week. High tides will occur from around 8am and pm today then about 50-60 minutes later each day into next week. Presently, it appears that it will be decent moon-watching weather through the weekend but there is a risk of some spotty thunderstorms and showers Saturday night and a hazier sky on the following 3 nights as the humidity ramps up. Next week, some weak disturbances in the upper level wind field may spark some scattered showers and boomers mainly late each day especially north and west of Boston. Looking way ahead, there might not be much of a break in the summery heat and sticky conditions until late next week when a beefier cold front arrives from Canada.
Here are some checkpoints this morning: 1. A Tropical Depression located over the Bay of Campeche may blossom into Tropical Storm Barry before weakening over Mexico tomorrow. Check in with the National Hurricane Center for more details. 2. Severe thunderstorms and isolated tornadoes are possible today over portions of the Western Plains and the Front Range of the Rockies. 3. Baked Alaska! A crazy heat wave has existed over “The Last Frontier” over the last few days. There have been some all-time record high temperatures in places up there. Typically well below zero much of the time in the winter, Fairbanks has been warmer than Miami lately and will be near 90 this afternoon! It will be turning cooler up there soon.
Todd Gutner posts his blog early this evening and I shall return early tomorrow morning.
Make it a great day!
