A really nice stretch of summer weather is ahead for those of us who would like it to be a bit warmer before the summer is completely gone. The trough which has been in place across the northeast in lifting out and with it will come warmer temperatures with a flatter flow to the upper level winds which allow hotter and more humid air to arrive in the the northeast. BUT...today is none of the above! In fact, we have some cooler air being directed back into New England by our NW upper level winds before the trough officially lifts out.
Not only will will temperatures be cooler down at the ground with highs in the 70's and lwr 80's Thursday, cooler air will still remain above our heads. This means morning sunshine will give way to building afternoon clouds again. An upper level disturbance will swing through which may even trigger a shower across the north country. Overall, Thursday will be a gem of a day with low humidity and light west winds.
High pressure will stay south of New England and wrap in a warmer SW wind Friday with highs in the mid 80's with sunny to partly sunny skies. A weak cold front will slide and stall over New Hampshire Saturday. This front will likely trigger a few widely scattered showers or a thunderstorm from the midday to the afternoon Saturday with highs still in the mid 80's. Once this front is through, the heat as on!
Hot high pressure follows in Sunday with sunshine, and highs climbing to near 90. A more humid feel will come with this heat as well. Sunshine and hot conditions will last all day Monday and Tuesday with highs in the Lwr 90's. So a potential heat wave is in the cards. It appears Tuesday will be the day we will break down the heat and humidity with some afternoon scattered storms, and downpours. The front will push off the coast Wednesday with a more seasonal airmass in the Lwr 80's with less humidity and increasing sunshine. There is plenty to like about this upcoming forecast for mid-August standards!
