September 20th Update
Monday’s rain will prove to be the exception as a mainly dry weather pattern rules through the end of September. Wednesday through Friday all look relatively warm, but less humid than the start of this week. Fall’s here on Thursday, but it will feel more like summer. A cold front passes through early Saturday, and a cool shot follows for most of the weekend.
The temperature will likely be seasonable or slightly cool for the last week of the month. However, the first 3 weeks have been so warm, it may still finish as one of the warmest Septembers on record.
Wednesday, Thursday and Friday all look partly to mostly sunny. Highs will be in the upper 70s to mid 80s – warmest inland. It will not be humid Wednesday and Thursday. It may get a bit muggier on Friday, especially late in the day. Lows will be in the mid 50s to low 60s Thursday and Friday morning.
A cold front moves through New England Friday night into early Saturday. A few showers are possible as the front passes by Friday night through about 8 AM on Saturday. The front will usher in much cooler weather for the weekend. Highs will be in the mid to upper 60s on Saturday under partly to mostly cloudy skies. It will turn cooler Saturday afternoon. Lows will be in the 40s to low 50s on Sunday. Expect some sunshine, but cool temps on Sunday. It will be breezy with highs in the low to mid 60s.
The relatively cool weather stays with us on Monday. It may be the coolest morning of the season so far. Lows will range from the upper 30s to low 40s in the countryside, to mid to upper 40s elsewhere. Look for sunshine with highs in the 60s. Tuesday looks mainly dry with showers possible Tuesday night. Temperatures will be close to normal through next workweek.
