You have another warm & humid day with many towns repeating yesterday's weather. That means we start with clouds & fog for a bit before hazy sun gets going. That hazy sunshine will boost temps up into the low 80s by early to mid afternoon across much of the region. At the same time a cool front will begin dropping out of Maine (backdoor front) which will quickly send temps from the 70s/80s down into the 50s/60s by late afternoon & evening. Also, when this front rams into the warmth & humidity it will spark a few showers & thunderstorms during the afternoon.
This front will spend the night with us and then head back up into northern New England tomorrow. That means we are right back into the warmth & humidity tomorrow as most cities & towns easily reach the low 80s. I don't think there will be any organized clusters of thunderstorms but a few will pop up in the afternoon heat.
On thursday, it's warm & humid yet again with afternoon highs into the low 80s with summertime humidity. There will be a higher chance of thunderstorms on Thursday afternoon-evening as a cold front plows into the heat & humjidity. The cold front will be the same front that is spawning severe weather in the plains states but it will be much weaker here in New England. Despite the weakened cool front there will be a risk of some severe thunderstorms late in the day---at this time, tornadoes are not expected.
In any event, cooler & less humid air arrives during the day Friday & hangs with us for much of the Memorial Holiday Weekend.
