Forecast: A Sunny, Mild Day Before Cold Front Moves In

Today is the last sunny and mild day for quite a few days. This morning has been bright and chilly, but the afternoon will turn milder with temperatures reaching the lower 60s.

You can thank high pressure for the fine day and blame a cold front for the upcoming chill.

I spent much the second half of yesterday getting plants ready to be brought inside this weekend. The growing season is likely going to come to a crashing halt Sunday night and early Monday when temperatures fall well into the 20s outside of the urban centers. I don’t expect Logan Airport to record an official freeze, but if you live in the less urban parts of Boston, such as West Roxbury, Hyde Park and even parts of Brighton, plan on a frost.

There are several cold fronts moving through that will be bringing the unseasonably cool air through Saturday. The final front has the coldest air behind it and also will bring wind. I expect Sunday to be the coldest and windiest day of the weekend and you’ll definitely need warm jackets, hats and even gloves if you are a spectator at any of the many events this weekend.

High temperatures Sunday will be nearly 15 degrees below the 30-year average and more conducive to Thanksgiving, not the final races of the Head of the Charles Regatta.

A flow of warmer air returns for the middle of next week with a period of Indigenous Summer (formally known as Indian Summer) on the way. Highs by Wednesday afternoon will reach the mid-60s! Winter isn’t here yet, but it will certainly feel that way Monday morning.

Today: Sunny, high around 60 degrees.

Tonight: Partly cloudy, with a low around 45.

Friday: Early clouds and a sprinkle, then sunny and seasonable. Highs 59-64.

Saturday: Early Clouds and then sunshine. Highs in the mid to upper 50s.

Sunday: Sunny, blustery and cold for October. Highs 45-49.

Monday: Sunny, with a high 45-50.
