DAYS 1-5 (SEPTEMBER 29 – OCTOBER 3)

The feel of the cool side of early autumn has arrived and will continue for a few days. Upper level low pressure will still be over the region through Thursday and a disturbance brings the chance of some shower activity from late today into Thursday, though most of this time will be rain-free. The upper low pulls far enough east to eliminate the shower threat by Friday, so the end of the week and at least the start of the weekend will be dry. The question to answer is whether or not the dry weather lasts through the weekend. There are already indications that “spill-over” moisture, or an area of unsettled weather coming up over a ridge of high pressure to our west will slide down on a northwest flow and potentially at least cloud us up for Sunday if not bring some rain into the region, but enough dry air may be in place to hold this off at least for a while. Also, this is a reminder if you have plans near the coast to be aware of increasing ocean swells / surf and rip current risk by this weekend as a result of distant offshore Hurricane Sam.

TODAY: Variably cloudy. A late-day shower possible favoring southern NH and northern MA. Highs 61-68. Wind NW to N 5-15 MPH.

FRIDAY: Sunny start then a sun/cloud mix. Highs 60-67. Wind NW 5-15 MPH.

FRIDAY NIGHT: Mostly clear. Lows 38-45 interior areas, 45-52 immediate coast and urban centers. Wind N under 10 MPH.

SATURDAY: Mostly sunny. Highs 61-68. Wind variable up to 10 MPH.

SATURDAY NIGHT: Partly cloudy. Lows 41-48. Wind variable up to 10 MPH.

SUNDAY: Variably cloudy. Chance of rain at night. Highs 59-66. Wind variable to SE up to 10 MPH.

DAYS 6-10 (OCTOBER 4-8)

At least the first half of this period is vulnerable to unsettled weather with periods of rain as it appears we’ll be in the battle zone between high pressure to the north and low pressure nearby or to the south. There is still the chance that high pressure wins the battle and the region ends up drier, especially later in the period.

DAYS 11-15 (OCTOBER 9-13)

High pressure should be more dominant with drier weather in this stretch of time, and we should also start to see a transition to more westerly flow again in the larger scale pattern.
