DAYS 1-5 (AUGUST 15-19)
And now we reach the half-way point of the month of August and the start of a new week. Today will be a fairly nice day with high pressure hanging on, providing a sun/cloud mix and modest humidity with seasonable warmth. The high gives way to a broad circulation of low pressure which will result in a cooler but more humid onshore air flow for Tuesday and Wednesday. We’ve been over the ups and downs on the guidance and all of that, but leaving out the rollercoaster details, I am going to tell you that my strong leaning now is for a drier forecast with more of a scattering of shower activity from later Tuesday through Wednesday. There is just enough evidence to still leave the door open for a more widespread swath of showers / rain for northeastern MA and southeastern NH on Wednesday, but don’t be surprised if I have to pull back from this on the next update. In short, not a whole lot of drought relief is in store for us despite it looking a little more promising previously. Later in the week, high pressure retakes the region with fair weather returning and a warming trend as well.

DAYS 6-10 (AUGUST 20-24)
Increasing humidity, but slowly, during the course of the August 20-21 weekend. Mainly dry weather is expected overall, but a shower threat may present itself later in the weekend. A bout of higher humidity and opportunity for a few showers and thunderstorms at times early to middle portion of next week with a general southwesterly air flow dominating.
DAYS 11-15 (AUGUST 25-29)
Still looking for a southwesterly to westerly air flow in general with limited rain opportunities and near to above normal temperatures into late August.
