DAYS 1-5 (AUGUST 8-12)
Our region will be between an approaching cold front from the north and a weak area of low pressure to the south today with lots of clouds around. Showers are most likely near the South Coast in association with the low to the south, but the approaching front will trigger a few showers in southern NH and MA during the day as well, though these will be rather isolated. Lingering showers are expected tonight with the low to the south while any showers that developed ahead of the front will fade and dissipate early on. The front will slip through the region and high pressure to the north will switch the wind around to the east across the area for Monday, with cooler but still slightly humid air. A few additional showers into Monday will favor areas mostly from I-90 southward as the frontal boundary and low pressure area will be sitting just south of New England. The low will weaken and move away and the front will come back northeastward as a warm front during Tuesday, opening the door for a more classic summertime feel by midweek with a warm to hot and humid southwesterly air flow and the daily chance of a few showers and thunderstorms both Wednesday and Thursday, with the greater chance of those being on Thursday afternoon.

DAYS 6-10 (AUGUST 13-17)
Heat, humidity, and thunderstorms as a cold front approaches on August 13. Front pushes offshore and high pressure moves in with drier weather for the August 14-15 weekend then high pressure may remain over the region with continued dry weather through the end of the period.
DAYS 11-15 (AUGUST 18-22)
Overall pattern looks dry with high pressure in control, but high pressure should sink to the south with time allowing it to become more humid again with an eventual increase in the shower and thunderstorm chance. We may also need to keep an eye on potential tropical activity in the Atlantic off the US East Coast by later in the period.
