DAYS 1-5 (MAY 22-26)<\/p>\n\n\n\n
This weekend will feature a preview of summer, followed by a reminder on Monday that it is not really summer just yet, followed by a reminder toward the middle of next week that summer is just right around the corner. Fickle. Fitting. Fast-changing. That’s our weather, and it will be on display for you to love, loathe, or just experience, depending on your preference(s). We start today where we have been for a couple days now, on the eastern side of an upper level ridge of high pressure, where the wind above us is blowing from the northwest, but at the surface a general southerly to westerly air flow means higher humidity and very warm to even hot conditions this weekend. With a fair amount of cloud cover much of the time today, the temperature will not reach the levels it would have under a clear sky with full sunshine, but you will notice it becoming rather warm after a modestly mild start, and the most sensitive will notice an uptick in humidity as we go through the day. The northwesterly air flow above us will be transporting yet another disturbance down across New England from Canada, and this, combined with what heating we do get from the sun, will pop a few isolated showers and possibly a thunderstorm this afternoon and early evening. While most areas will likely escape this activity, the few areas that do see it can be visited by a brief downpour but more likely a lighter shower. Bottom line: you probably won’t get wet, but if you do, it won’t last long. Sunday will feature more sunshine but a bit more wind ahead of an approaching cold front which will be heading rapidly southward out of Canada into New England. Before it arrives, many areas will make a run at 90 and some may reach or exceed it for the first time this year. While the dynamics are not there for a widespread thunderstorm outbreak, the front is likely to trigger at least scattered showers and storms, a few of which may be on the strong side. So if you have outdoor plans, pay attention to the sky (and a radar app if you have one), especially during the afternoon. By Sunday night, the front will be exiting via the South Coast and we’ll already be feeling the change to a much cooler air mass, which will be in control of Monday’s weather as high pressure moves in from southeastern Canada. Many areas will be 18 to 25 degrees cooler for high temperature on Monday than they will be on Sunday. But this cool-down will be short-lived, as the same high pressure area that brings the cool air will settle to the south of New England by Tuesday and the return flow around it from the southwest and west will warm us right back up, lasting into Wednesday when we may heat up about as much as we do on Sunday. And another front will approach later Wednesday with a shower and thunderstorm threat, but that being 5 days away I can’t speculate much on that particular event at this point.<\/p>\n\n\n\n
TODAY: Variably cloudy. Isolated showers and a slight chance of thunderstorms in the afternoon and early evening. Increasing humidity – dew point approaching 60. Highs 68-75 South Coast, 75-82 southeastern MA not at immediate coast, and 83-90 elsewhere. Wind SE to S up to 10 MPH early, becoming SW 5-15 MPH, but local sea breeze possible.<\/p>\n\n\n\n

WEDNESDAY: Partly sunny. Chance of afternoon showers\/thunderstorms. Humid – dew point over 60. Highs 85-92 except cooler South Coast. Wind SW 10-20 MPH.<\/p>\n\n\n\n
DAYS 6-10 (MAY 27-31)<\/p>\n\n\n\n
High pressure from Canada brings cooler\/dry weather May 27. Uncertainly on how the last several days of May play out, including the May 29-31 Memorial Day Weekend. For now thinking we may need to watch for a wave of low pressure bringing some wet weather around May 28-29 then high pressure moving in with drier weather, but this is very low confidence and may look rather different to me just 24 hours from now.<\/p>\n\n\n\n
DAYS 11-15 (JUNE 1-5)<\/p>\n\n\n\n
Air mass boundary in area the first several day of June with variable temperatures and at least a couple opportunities for showers\/thunderstorms. No early indications of any extreme temperatures.<\/p>\n","protected":false},"excerpt":{"rendered":"
