Second Heatwave of the Season for Some

We have ourselves at the beginning of our second heatwave here in southern New England. Right now at 12:30PM at Boston, the temperature is sitting at 87 degrees. Barring a seabreeze, Boston will have no trouble hitting 90 this afternoon. We will do it again tomorrow and Friday, but the humidity will get very high tomorrow and Friday and it will feel much more hot than what it feels like right now. Right now the dewpoint is sitting around 60, making it only feel slightly humid. Tomorrow, the dewpoints should get into the mid and upper 60's and by Friday and Saturday, we should get to near oppressive levels, nearing 70 degrees. With the increased humidity, the threat for rain will increase as well. The upper level low that drenched NYC with 2-3" of rain this past Monday will be heading back east, this time loaded with tropical downpours. It will link up with a front coming down from Canada, which will help to wring out all of the moisture in the air. Sunday looks to be the wettest day, but the rain should start as scattered showers and storms on Saturday, mainly in western and northern New England and then migrate east by late day to get eastern New England. Temperatures will be cooler with the rain cooled air, mainly in the mid 70's on Sunday, upper 70's on Monday, but we will not have to deal with the cold air we had on Monday with highs struggling to get out of the mid 60's, very odd for this time of the year.
