Tropical Air Mass
Posted by Chris Lambert
Ever been to Florida in the summer? If you have, you know one thing's for sure, when it rains, it pours. With a tropical connection to moisture across New England, sky high humidity and quite a bit of instability, we'll see Florida-like downpours at times. You also know, a good portion of a summer's day can also be dry despite the occasional torrent of rain.
So how would I rate this weekend? The answer to that question is tricky. Take yesterday for example. We had quite a bit of sunshine for many in the afternoon, but some towns in the western half of the state picked up 2-4" of rain! So location is everything it determining how your day is with the hit and miss storms. Clearly when it hits, it hits hard, in fact, we've already seen 1-2" of rain with a thunderstorm that rocked the Cape this morning.
In terms of the timing of storms today, early morning breaks yield to a few scattered showers mid to late morning for many. Then more breaks early this afternoon before more scattered storms develop. The higher threat of stronger storms this afternoon tends to favor near and outside 495. With that said, bottom line, you'll get dry hours in through the day for a cookout, or a ballgame, but be prepared to duck these storms once and awhile. Check our 7Weather App if you want a handy radar on your phone.
It's a rinse and repeat for Sunday. Then higher rain chances Monday and Tuesday. Wednesday through Friday feature hazy sun, clouds and the occasional storm, but we'll get our dry hours in too. Humidity stays sky high all week with dew points running close to 70 degrees.
Where will we rank after this weekend in terms of wettest Junes? Right now, Boston is in 3rd place this year with over 10" of rain (10.32"), the rainiest June on record was 1982 with 13.20". We'd need a tropical downpour to sit right over Logan Airport for a couple hours to beat that, so the chance of that is low. How about 2nd place? That belongs to 1998 with 11.58". We would need 1.27" to break into the number 2 slot, which is possible if a few storms line up over the city.
Stay dry, stay cool and have a good weekend!
