Warmer weather is moving back into Southern New England early this week, but, initially, it will not be accompanied by high humidity. The dew point was in the upper 50s to low 60s at mid-morning on Monday, and it is not expected to get above the low 60s for the next couple of days.
The impact of the humidity can be felt in a couple of ways. First, if the air is humid, it will not be as cool at night. The low temperature should be in the low 60s on Tuesday morning, and in the mid to upper 60s Wednesday and Thursday mornings. That is a bit warmer than normal for late-August, but nothing like what we saw in July when the low temperature was 70° or warmer at TF Green 19 times.
Another impact from high humidity is the heat index – or what it feels like outside when the temperature rises into the 80s. When the humidity is very high, it can feel several degrees warmer. Even though Tuesday is expected to be in the mid to upper 80s, it will not feel much warmer because the dew point should be in the upper 50s to low 60s.
The humidity will peak just a head of a cold front that is slated to move through Southern New England Thursday night into early Friday. The dew point will drop Friday into the weekend as a cold front passes and drier air moves in from Canada.
