Thoroughly Unpleasant Weather Continues Today

Hello everyone!

Today will feature another day of thoroughly unpleasant weather as temps remain high and humidity only gets higher. Highs will once again range from the upper 80s in the far north and along the immediate shorelines to the low 90s inland and dew points will surge into the dreaded lower 70s. This means heat index values in the low to mid 90s across the area. If you have to be outside and not submerged in water today, be sure to drink lots of water and stick to the shade if possible.

This airmass will prove fertile for afternoon showers and thunderstorms, though the mechanism by which the atmosphere will initially be perturbed to set off storm development is a little unclear. One option is a cold front entering the region from the north around sunset, while another seems to be a subtle convergence boundary draped over southern NH. Thus the highest chances for thunderstorms this afternoon will be up in the mountains and down near the MA border, though I can’t rule out a brief shower anywhere. Storms today will mostly pose a heavy rain threat given the absurd amount of moisture we have around. Lightning and gusty winds are also possible.
