Weekend Forecast: Chilly Friday Morning, But Very Warm Sunday On Its Way

If you left your windows open Thursday night, it’s likely very cool in your house.

I’m not sure if you turned your heat on yet, but Friday morning is one of those mornings that temps me to put it on. Later Friday afternoon temperatures will rebound to the upper 50s, which is quite a bit below normal. The sun is getting lower and lower in the sky, so it will remain very chilly in the shady spots throughout Friday.

A cold front went by the area Thursday evening and allowed this quick shot of cold air to move through the area. Frosty — even freezing — conditions were seen Friday morning across northern New England, where some regions have now seen an end to their growing season.

If you don’t like the cold, don't fret. It’s not going to last very long. Although Saturday morning will also be chilly, Saturday afternoon’s highs will reach the upper 60s, rising to nearly 10 degrees warmer than today. There should also be lots of sunshine Friday and Saturday.

Sunday is still looking like a summer-like day with highs near 80F and light winds. There will be some clouds later in the afternoon, but I still think Sunday is going to be a great beach day. There might be a shower late Sunday evening before the weather turns more seasonable early next week. If Boston doesn’t see any significant rain the rest of the month, this is going to be the driest September in 57 years!

Friday: Sunny and noticeably cooler. Highs in the upper 50s to near 60.

Friday night: Clear and chilly. Lows 38-44.

Saturday: Mostly sunny milder. Highs 65-70.

Sunday: Lots of sunshine and warm. Highs 75-80.

Monday: Mostly sunny with a high near 70.

Tuesday: Mostly sunny with a high in the mid 60s.
