Drought Monitor’s weekly update launched Thursday morning and recent thunderstorms just weren’t enough to stop the slide for eastern Massachusetts and southern Rhode Island, now upgraded from Severe Drought to Extreme Drought by the government/university consortium that publishes the national assessment.
We’ve seen some improvement in northern New England, with much of the Upper Valley and mountains slipping out of dryness thanks to recent thunderstorms accompanied by torrential downpours. Although very limited rain will fall in parts of New England on Thursday, it won’t impact the drought – amounts will be fairly light, around a tenth of an inch or less, even in where the rain is most constant.
Many clouds during the day drop rain showers from the Boston Metro to southeast Connecticut, ending west to east, early afternoon to early evening, north- west to southeast. Further northwest, scattered showers in northern New England on Thursday will not creep into central New England or central western Massachusetts and Connecticut, where the day is expected to remain dried.
Thursday evening brings the full New England Sturgeon Moon, rising just after 8 p.m., officially reaching full just after 9:30 p.m. and the last “Supermoon” of the year, just a little closer and a little brighter. than a typical full moon, and exert just enough gravitational pull on Earth to provide tide levels high enough for very minor coastal spattering and flooding in places typically vulnerable to high tides around midnight Thursday and Friday night.
Thinning clouds on Thursday evening will not only give way to a view of the Super Moon, but also glimpses of the Perseid meteor shower, which is expected to peak Friday evening but is already visible with occasional meteors in our night sky.
As the night progresses, partly cloudy skies will eventually combine with pockets of dense fog in eastern New England that will persist through Friday morning before clearing up. Friday will feature more clouds than sunshine as a large area of upper level energy slowly gathers over the northeastern United States, bringing scattered afternoon rain showers, particularly in eastern New England, as high temperatures reach around 80 degrees with a moderate amount of humidity.
New Englanders may want to get used to the feeling of temperature and humidity over the next few days, in season for this time of year, but also where we’ll be landing for pretty much the entire forecast at 10 days from the first alert. The risk of showers fluctuates as various upper atmospheric disturbances impact the jet stream winds aloft, stationed over the northeast next week and thus increasing the risk of showers over several days in the forecast at 10 days, but particularly centered around midweek next week.
