DAYS 1-5 (OCTOBER 1-5)
The month of October starts with a fairly nice day as high pressure approaches from the west, but the previously-mentioned “pinch” will be taking place as we have lingering influence from low pressure to the east and an approaching disturbance from the west. The low to the east will try to force this moisture to the southeast but it will run into dry air as it does that, so while cloudiness comes across our sky at times this weekend, I expect the weekend for southeastern New England to be a dry one. If you’re heading north though, you may run into some wet weather at times. The temperature forecast is a little tricky as we get into Sunday as it will depend on the position of a frontal boundary in the region. Finally, the moisture from the west will make it into the region by Monday, which looks like a wet day, and this may hang around into Tuesday before high pressure to the north regains foothold and starts to push the moisture off to the south. How quickly this happens is somewhat uncertain at this time. Also remember if you have plans near the coast this weekend, be aware of increased ocean swells / surf and rip current risk as a result of distant offshore Hurricane Sam.

DAYS 6-10 (OCTOBER 6-10)
High pressure is expected to sit over and just north of the region with fair and seasonable weather. We need to watch low pressure sitting to the south of the region, especially toward the end of the period.
DAYS 11-15 (OCTOBER 11-15)
Battle between high pressure to the north and low pressure to the south may be won by low pressure again before this period ends, and then by its end we should get into a drier westerly air flow. Low confidence forecast.
