DAYS 1-5 (OCTOBER 15-19)
A dry pattern is in control. Cool weather dominates through Thursday. Atlantic Canada low pressure combined with Midwest high pressure drives a northwesterly breeze across the region today with plenty of sun overall, but some diurnal cumulus and stratocumulus developing, most prominent in the hills well west and north of Boston, while some streamers of high clouds cross the sky from the west southwest during the afternoon hours. Previously felt there could be more clouds Wednesday, but no longer so. High pressure exerts more control while the influence of upper level low pressure is gone sooner, and there is more sun, similar to today at “worst”. Thursday’s weather will be influenced by an ocean storm well offshore to our southeast, but close enough to turn the wind more northerly, and also extend a cloud canopy over the South Coast / Cape Cod for a while – though I do think any rainfall with this low will remain over the ocean. High pressure exerts more influence late this week along with a moderating temperature trend.

DAYS 6-10 (OCTOBER 20-24)
Dry spell continues until late period when there’s finally a threat of some unsettled weather. Temperatures near to above normal through mid period before a cooling trend.
DAYS 11-15 (OCTOBER 25-29)
A more dynamic pattern may evolve, but that doesn’t necessarily mean stormy. It may mean more stark temperature contrasts and at least one bout of unsettled weather. Much to monitor and fine-tune.
