DAYS 1-5 (MAY 18-22)<\/p>\n\n\n\n
A back-door cold front went through the region overnight and sets us up for a dry but cooler day today. The region overall will be a good 10 to 20 degrees lower than yesterday, which was quite a bit above normal, meaning that today will really not be that bad outside, just decidedly “less warm” than Sunday. Coolest readings will be along the east-facing and north-facing shores where wind is directly off the water. We’ll see some clouds scooting west to east across the sky, particularly in northern MA and southern NH, as warmer air is already returning aloft while the surface remains as described above. The much-talked-about summer preview arrives Tuesday with high pressure building to our south, driving warm to hot air and somewhat higher humidity into the region. While it won’t be oppressively humid, by definition, the fact that it’s early season moderate humidity will make it feel a bit worse in a relative sense, since we have not had a chance to adapt as we would by summer. An active breeze from the southwest will be a help, however, and this breeze coming off the Atlantic waters to the south will, of course, keep the South Coast \/ Cape Cod, and even to the southern portion of the MA South Shore less hot than the remainder of the region that has a pure land breeze. One thing to keep an eye out for later Tuesday is the potential for a few showers and thunderstorms in advance of a pre-frontal trough approaching from the northwest. The greatest chance to see these would be in northern MA and southern NH in the late afternoon to early evening hours. Most areas will remain dry, however, as coverage would be fairly limited. Any of those fade away or move out quickly and we’re left with a fair and very mild night, leading to the summery feeling continuing on Wednesday. The difference this day is that it will be cut off by an approaching and passing cold front, bringing more clouds and a better chance of showers and thunderstorms to the region. I still have to refine the expecting timing of this front in the next couple of updates, but for now I am leaning toward it being a quick enough passage that the greatest shower and thunderstorm chance may be from the I-95 belt southeastward. This will lead to fair and cooler weather Thursday and Friday as high pressure builds into the region.<\/p>\n\n\n\n

DAYS 6-10 (MAY 23-27)<\/p>\n\n\n\n
Memorial Day Weekend (May 23-25) looks cooler with high pressure to the north. Watching low pressure to the south and for now I continues to lean toward the greatest potential for wet weather to be later Saturday into Sunday with improvement for Memorial Day. Still a high degree of uncertainty on this outlook, so follow updates! An upper low hangs around with cooler weather and a few pop up showers possible into the middle of next week.<\/p>\n\n\n\n
