Coastal Relief Today, Otherwise Hot and Not as Humid

Good morning! Today is Monday, September 1, signaling the beginning of meteorological autumn (or fall – I find myself using both). But with a ridge of high pressure. we will remain mainly dry and hot for the foreseeable future, with the caveat of today, as a cold front will affect mainly coastal regions. There will be generally light winds, starting out in a general northerly direction for most before shifting to a west wind across inland areas, and an onshore flow at the coast. Brilliant sun is likely throughout New England today, with perhaps some scattered high clouds.

Guidance is split on the effects of a minor backdoor cold front and the associated wind shift along and near the coast; at least regarding how far inland effects reach; that is the only real uncertainty for today.

Highs today will reach the low to mid 70s in Northern and Eastern Maine; the mid 70s across much of northern Vermont, higher elevations and the far northern extent of northern New Hampshire; extreme northwest Maine; and just about anywhere that’s right against a coast; upper 70s across much of the remainder of Vermont; the lower elevations of northern New Hampshire; much of interior central Maine, and just about anywhere that’s near but not right at the coast. Lower 80s in inland eastern Massachusetts, interior southwest and west-central Maine, the Connecticut River Valley of east-central Vermont, much of central New Hampshire away from the Concord/Merrimack River area, the Berkshires; interior southeast Massachusetts; and much of southern Vermont; middle 80s in a large swath of the rest of Massachusetts, southern New Hampshire, and northern Connecticut; localized upper 80s are possible in this region.

Dewpoints will be dry across the region, between the upper 40s for dewpoints in northeast Maine and the low to mid 60s in southwest Connecticut; dewpoints in the 50s will be the rule for much of New England today. Dewpoints in the lower 60s also cannot be ruled out right along the eastern coast from Portland southward. Dewpoints will begin rising in the late evening hours.

Have a good day!
