In what looks like a pattern a little more typical of springtime, but can sometimes happen in autumn too, low pressure sits south of our area and between it, and high pressure to the north, a persistent broad onshore flow continues today along with bands of rain with embedded heavier showers (maybe even some thunder especially to the south). This rainfall has been a little more expansive in coverage than I had anticipated it might be, but not continuous as there are breaks in it at times. However, there have already been some amounts of 2 inches or higher especially in the South Shore region of MA, and this gets added to today as the rest of the region adds some up as well. While you may be tired of a long stretch of cloudy and occasionally wet weather, this again has been generally beneficial to continue reducing the ongoing drought across most of the region. However if you are looking for some nicer weather, you’re going to see it as vastly improved conditions – fair and milder – take place Thursday into Friday as high pressure shifts quickly over then south of the region in the wake of the departed low. This low, the remains of what was once Hurricane Ian, will have produced a range of after effects from devastating damage in Florida to beneficial rainfall in New England. Don’t get too used to the mild spell, which will be brief. A cold front will whistle across the region from west to east late Friday, maybe producing a rain shower, but definitely opening the door for a chilly October air mass from Canada for our weekend. This will come along with mainly dry weather and a gusty breeze. A secondary cold front crossing the region later Sunday may bring a brief passing rain shower.

DAYS 6-10 (OCTOBER 10-14)
High pressure builds across the region early next week with fair weather and a chill, then moderating as the high center shifts offshore to the east. Warm front / cold front combo seems timed for the October 12-13 period when there may be brief light rain / rain showers and milder air, before another shot of chilly air from Canada to end the period.
DAYS 11-15 (OCTOBER 15-19)
Any warm-up will be brief as additional shots of chilly air await in Canada to move this way in a west northwesterly air flow with mostly dry weather. Brief precipitation episodes can accompany any air mass change.
