DAYS 1-5 (JUNE 4-8)<\/p>\n\n\n\n
A weakening cold front \/ trough will move through the region today. Showers and possibly a few thunderstorms will be initiated by this system combined with humidity in place and daytime heating, with most likely a broken line of convective activity forming somewhere in southern NH and central MA early this afternoon then progressing southeastward with time. Before that, some shower activity is also possible again near the South Coast where there is also more low cloudiness and fog in place due to higher dew point air in that region. The rest of the region does get into higher humidity today as well as the trough \/ front moves through. The shower and potential thunderstorm activity that it generates will be non-severe, but a few of them can produce brief heavy downpours and short-lived bursts of gusty wind, so be on the look-out for that especially if traveling. Tonight, any remaining activity diminishes as it moves across the South Coast region, which may still be mired in some low clouds and fog, and with temperatures falling a bit to meet the still relatively high dew points this evening we may see areas of fog forming elsewhere in the region before finally some drier air arrives from the west toward morning to clear it all out. At most we may see some lingering cloudiness around early Saturday, otherwise the sun will take over as high pressure builds in both at the surface and aloft, and this pattern strengthens during the weekend into early next week bringing much of the region its first heat wave of the season (heat wave being defined as 3 or more days with a high temperature of 90 or higher). There will be exceptions, most especially the South Coast, where a southwesterly component to the air flow is off the water and will keep it cooler there. There are a few land protrusions along the East Coast of MA that may also fail to reach 90 on one or more of these days for the same reason, but in general, the heat will be on for most during this time. There will be a frontal boundary not all that far to the north of the region at times, especially Sunday, and then after being pushed northward Monday it approaches again later Tuesday, but for now the expectation is this boundary will stay far enough north to have no impact on the weather here.<\/p>\n\n\n\n

Scattered to numerous showers and possible thunderstorms southern NH \/ central MA early afternoon through eastern MA \/ northeastern CT \/ RI later afternoon. Highs 73-80.

DAYS 7-10 (JUNE 9-13)<\/p>\n\n\n\n
Upper level high pressure ridge axis shift westward enough to allow a cold front down from eastern Canada which may bring clouds and a shower at some point June 9 but mainly a cool-down back to the upper 70s and 80s. This boundary won’t be that far to the south and may allow some disturbances to ride along it producing at least some cloudiness at times and potential a few threats for shower activity in the region June 10-11 while we’re on its cooler side before it may lift back to the north and put us on the warmer \/ humid side with a shower or t-storm risk June 12-13. Don’t interpret this as a wet and cloudy pattern, just some activity to follow with the frontal system in the vicinity.<\/p>\n\n\n\n
DAYS 11-15 (JUNE 14-18)<\/p>\n\n\n\n
Expecting a mostly zonal (west to east) flow pattern with variable temperatures and a couple shower threats from passing disturbances, but dry weather most of the time.<\/p>\n","protected":false},"excerpt":{"rendered":"
