    Hazy, hot and humid. Temperatures in the low 90s.

    (Published Wednesday, July 19, 2017)

    Heat indices soared into the mid-90s this afternoon as the blazing sun combined with humidity to wither some communities.

    On a day when thunder might have been welcome, all we saw was a 5-minute downpour flare up near Marshfield, MA. Sure, there was a front floating above Burlington, Vermont, but there was nothing in the upper atmosphere to support it and get organized storms to fire.

    We're looking at the steamy prospects of another day in the heat and humidity tomorrow. With highs again approaching the low 90s in Southern New England, you might hear the beach or the lake calling again. If you can't heed the call, at least take it easy and find some A/C.

    As this cool front settles across Southeast Mass, Rhode Island and Connecticut tomorrow night, a burst of energy will ripple overhead in the jet stream. This may spawn a few late night storms across the region, with the focus on Connecticut and Rhode Island. If they do form, beware of frequent lightning and intense bursts of rain. These things are fickle when they try to form over New England. Many times they revert to just a few passing showers...but sometimes they overachieve and startle a lot of people in the middle of the night.

    End result will be a slightly cooler day Friday and a slide into the 70s by the end of the weekend. Speaking of, it starts nice and then succumbs to clouds by Sunday afternoon. Looks like we may hold back the showers until late, but this is a work in progress. If our weather system speeds up, we might be seeing them by early afternoon.

    Stay cool!
