DAYS 1-5 (AUGUST 1-5)
A wave of low pressure that brought significant rainfall to a good swath of southern New England yesterday and early today will depart early today. Wet weather will come to an end this morning and midday from northwest to southeast across the region. As the large cloud canopy associated with the departing low pressure wave starts to clear out from northwest to southeast, we’ll see other clouds pop up due to lingering atmospheric instability, and these can lead to a few spot showers mid afternoon to sunset, although most areas will not see any. It will be a cool day, and while it is technically humid to start, it will dry out with lowering dew points. After this, high pressure builds in for the weekend and sinks to the south and east early next week, providing several days of fair weather, starting out cooler than average Saturday, warming to seasonable Sunday and a little warmer than average early next week – very nice summer weather!

High pressure shifts off the Atlantic Coast into mid month, with a pattern that would feature higher humidity and a slightly better chance to see some shower and thunderstorm development at times.
