Fall warm-up expected this week

MANCHESTER — Fall may feel a little more like spring this week.

After a brisk start to the week with Columbus Day temperatures in the 50s, New Hampshire is in for another mid-week warm-up before more seasonable weather returns.

“The general trend for recent years has been warmer for the months of September and October,” said William Watson, a meteorologist with the National Weather Service in Gray, Maine.

After one of the warmest Septembers on record, this fall appears to be following that trend.

While today’s forecast calls for cloudy skies and highs in the mid-50s, temperatures Tuesday and Wednesday will go back to being abnormally warm during the day and night, Watson said Sunday.

“The night-time lows will be what the normal daytime highs would be,” Watson said. “It’s a little bit of an anomalous thing for those couple of days.”

Overnight temperatures Tuesday and Wednesday are expected to drop only into the lower 60s. Tuesday is expected to be cloudy but still reach the upper 70s, followed by mostly sunny conditions Wednesday with highs again pushing 80.

“Those are easily 15 degrees above normal. It’s pretty unusual for this time of year,” Watson said.

While it won’t feel much like fall, it also may not look like it to visitors coming to see the Granite State’s display of fall foliage colors.

“Typically, an abnormally warm early autumn will reduce the color because it will extend the time that the chlorophyll is present in the leaves,” Watson said. “We are seeing a little bit of that.”

The chlorophyll is keeping the leaves on many trees green — for now. Just one week into the month, Watson said there is still plenty of time for the foliage to get back on track with the brilliant displays.

“We’ll have another frontal passage Wednesday night into Thursday and then we kind of get back to normal temperatures after that,” Watson said. “The front will also bring some good chances for rain and showers and bring us to more typical conditions for the weekend.”

Monday is also a holiday for some, so regular services may be affected. In Manchester, there is no trash pickup because of the holiday and collections will be running a day late for the week.
