DAYS 1-5 (JUNE 19-23)<\/p>\n\n\n\n
A warm front has nearly completed its journey across the region as of the time of this blog writing, and only a few lingering showers associated with it are traversing southeastern New England early this morning, soon to exit, leaving the vast majority of the day free of any shower threat. This is a slightly different forecast than previously, which had a shower and storm threat this afternoon, but right now it looks like the air will be stable enough to prevent more than a brief pop-up shower\/storm in isolated locations, and that the energy for showers and storms won’t really arrive until tonight, with a cold front that decided to hang back to the west before moving through. And by then, we’ll have lost a lot of daytime heating, leaving other atmospheric dynamics responsible for triggering and maintaining showers and storms, and the best of that may be passing across far southern portions of the region. What does that mean? It means that the shower and thunderstorm threat will most likely occur during the evening hours and the greatest chance of heaviest activity will be toward the South Coast, but we’ll have to monitor all areas, just to be sure. So if you have outdoor plans this afternoon, you can relax a little but still keep an eye out, and if you have outdoor plans this evening, be a little bit more aware. Still, I think most people get away with nothing more than a passing shower first thing today and again sometime this evening, and many see nothing at all. Any early clouds exit first thing Sunday as the cold front moves offshore, leaving us with a very warm day as there is not much cool air behind that front, but fairly comfortable air as the dew points which peak in the lower 60s today fall back to the upper 50s for Sunday. But don’t get “comfortable” (pun intended) because humidity is set to increase Monday and Tuesday. The higher dew point air will be re-introduced to the region as a warm front quietly passes through the region early Monday. The trend regarding that Gulf of Mexico low pressure area by guidance has been to either keep it as a compact low passing just south of New England or to dissipate it and have some of its moisture become involved with an approaching cold front. Guidance has also been split on the timing of that cold front, for example one model bringing it through on the earlier side Tuesday while another holds it back until later. The timing of that front with respect to daytime heating will have implications on how significant our shower and thunderstorm threat will be that day provided the Gulf low does not have direct impact and make it more of an overcast day anyway. So there are still some questions to answer regarding the forecast for Tuesday for our region. Regardless of those details, the cold front will be offshore and a pleasant polar air mass will arrive by Wednesday of next week.<\/p>\n\n\n\n

DAYS 6-10 (JUNE 24-28)<\/p>\n\n\n\n

DAYS 11-15 (JUNE 29 \u2013 JULY 3)<\/p>\n\n\n\n
A bit more west-to-east flow with overall drier but seasonably warm weather, and one or two disturbances to bring a shower or t-storm risk.<\/p>\n","protected":false},"excerpt":{"rendered":"
