DAYS 1-5 (JULY 24-28)
An adjustment of the weather pattern has occurred so we are no longer in the very humid, frequently rainy one, so even though you see shower and thunderstorm chances mentioned a few times in this 5-day forecast, it’s not going to be a wet week – in fact considerably drier than many recent times. We enjoyed some less humid Canadian-born air over the weekend, and it will still be mid-summer-comfy to start this week with humidity not that high today and Tuesday, and even not so bad into Wednesday even though we start to heat up a bit. We’ll be influenced by weak weather systems into mid week with minor boundary lines for dew point and a couple weak troughs will be in the region, and can help focus a few isolated showers and very low chance of thunderstorms any afternoon through Wednesday, with the extreme majority of the region remaining rain-free. By late Thursday, convection from a trough and frontal boundary moving into the Great Lakes can reach western and northern New England with a remnant of boundary-triggered shower or thunderstorm potentially making it into far northwestern reaches of the WHW forecast area by the evening hours, and the shower and thunderstorm chance then goes up for the remainder of the region Friday afternoon as the front presses closer. Thursday and Friday will be hotter and humid days as high pressure ahead of this front shifts offshore and builds in a more classic summertime set-up…

DAYS 6-10 (JULY 29 – AUGUST 2)
Frontal boundary moves through July 29, may start humid with showers and thunderstorms possible then lower humidity and cooling trend through July 30. High pressure builds in with mainly fair weather and more seasonably warm and moderate humid conditions July 31 through August 2.
DAYS 11-15 (AUGUST 3-7)
Indications remain for weak troughing, higher humidity, and some shower / thunderstorm chances – a weaker version of a pattern we’ve seen much of the summer. We may need to watch for tropical activity off the coast south or east of New England by the end of the period.
