Forecaster's discussionIssued 10/27/2026, 6:53 PM EDT

What has changed

No significant changes needed to the forecast with this evening update. Just made some minor adjustments to the Aviation Discussion for the 00Z TAFs.

Key messages

1. High pressure continues to dominate the weather for the coming week. Expect dry conditions and no significant weather impacts.

Discussion

KEY MESSAGE 1 DESCRIPTION:

High pressure settles overhead tonight and will set the stage for what is likely to be the coldest night of the season for most locations. Widespread 20s and some readings down into the mid to lower teens in the northern valleys are expected. We are also reaching the tail end of radiation fog season, but a couple hours of patchy fog around sunrise remains possible, especially south of the mtns.

The next cold front approaches Thu into Fri. Southwest flow will allow temps to warm back into the 60s and some 70s. The front itself looks to be largely dry again, with some showers most likely for the mtns and points north. Colder air will arrive first north of the mtns, so Fri may be closer to normal for those locations but still quite warm across the southern forecast area.

For the Halloween weekend high pressure returns with fairly typical late October temps. Then we look toward the start of November where the pattern looks to become more active again, which is not saying much after these last couple of weeks.

Aviation

Through 00 Thursday: With clear/calm conditions tonight there may be some patchy valley fog at LEB, CON, and MHT close to sunrise. Otherwise, VFR prevails through the day Wednesday.

Outlook:

Wednesday night: There may be brief period of IFR or lower in valley fog at LEB, CON, and MHT prior to sunrise.

Thursday: VFR conditions expected.

Friday: Another front approaches the region and some MVFR CIGs may be possible north of the mtns, including HIE.

Saturday-Sunday: VFR conditions expected.

Marine

Winds and seas expected to remain below SCA thresholds thru Wed under high pressure. As the high shifts offshore, southwest winds will increase Thu into Fri. Some gusts may approach 25 kt along with seas approaching 5 ft in the vicinity of Skate Bank. Overall I expect conditions to remain below SCA thresholds.

Watches, warnings and advisories

ME: None. NH: None. MARINE: None.

From the National Weather Service; may be delayed. Not for life-safety decisions. In an emergency, call 911.
