DAYS 1-5 (JULY 26-30)…
The humidity leaves, but the heat hangs on today, and as a west wind blows and dries the air out, it will really heat up during the day. Sunshine will be abundant today, and again Wednesday, but the difference will be lighter winds on Wednesday and coastal sea breezes. Boston’s 5-day heatwave will become 6 days today, but it is questionable whether or not they reach 90 on Wednesday, depending on the sea breeze timing. Regardless, many areas away from the coast will still reach or exceed 90 on Wednesday, though humidity will remain low. Thursday, a southerly flow will take over as high pressure slides to the east and a weak trough and cold front approaches from the northwest. Though it will not be as hot, an increase in humidity will make it feel hot still, and add to it a risk of a few isolated showers and thunderstorms later in the day. The weak cold front will make it through the region, barely, by early Friday, and a weak wave of low pressure will move along it. This will bring a risk of some rain to southeastern areas, with less risk to the north and west. By Saturday, high pressure from the north will push the remains of the front further south, bringing dry weather, but a lighter north to east air flow will keep heat away as well.
