DAYS 1-5 (AUGUST 13-17)<\/p>\n\n\n\n
High pressure shifted offshore overnight, introducing a south to southwest air flow, higher dew points, even a layer of stratus and some fog over many areas south of I-90 and in some hilly terrain of north central MA and southwestern NH. This is a little more aggressive intrusion of higher humidity that I had expected, and along with a trend in reliable short-range convective guidance leads me to conclude our thunderstorm chances are better today than I previously prognosticated. Since these will be triggered by an approaching cold front from the west northwest, the greatest chance to see them is north and west of Boston from the second half of the afternoon until around sunset, so anybody with outdoor plans or traveling should be aware of that chance. Prior to that, a very warm to hot day is ours along with that higher humidity. The aforementioned cold front will cross the region on Thursday, bringing the shower and thunderstorm chance south and east with it, and we’ll note it being a little less hot but still humid. High pressure builds in behind the front, bringing fair, pleasant August mid August weather for Friday and Saturday, before another short-lived heat and humidity spike ahead of another cold front Sunday, with the chance of some late day shower and thunderstorm activity ahead of that front.<\/p>\n\n\n\n
TODAY: Low clouds \/ fog patches southwestern NH, central MA, and most area south of I-90 into mid morning before sun elsewhere expands into these areas, but then gives way to a variably cloudy sky west to east later. Showers and thunderstorms possible mid afternoon on, particularly north and west of Boston. Highs 78-85 South Coast, 86-93 elsewhere. Dew point middle 60s to near 70. Wind S to SW up to 10 MPH, but can be strong and gusty near any storms.<\/p>\n\n\n\n
TONIGHT: Variably cloudy with a chance of showers and thunderstorms early, especially north of Boston, then partly cloudy with patchy fog forming. Lows 67-74. Dew point upper 60s. Wind SW up to 10 MPH.<\/p>\n\n\n\n
THURSDAY: Partly sunny. Scattered showers and thunderstorms likely. Highs 85-92 except cooler South Coast \/ Cape Cod. Dew point upper 60s. Wind SW 5-15 MPH.<\/p>\n\n\n\n
THURSDAY NIGHT: Partly cloudy. Chance of a shower early. Patchy fog. Lows 63-70. Dew point 60+. Wind SW to variable to NW up to 10 MPH.<\/p>\n\n\n\n
FRIDAY: Mostly sunny. Highs 78-85. Dew point falls below 60. Wind NW to N up to 10 MPH.<\/p>\n\n\n\n
FRIDAY NIGHT: Mostly clear. Fog patches interior lower elevations. Lows 56-63. Dew point near 55. Wind N under 10 MPH.<\/p>\n\n\n\n
SATURDAY: Mostly sunny. Highs 81-88, cooler some coastal areas. Dew point under 60. Wind N up to 10 MPH with coastal sea breezes.<\/p>\n\n\n\n
SATURDAY NIGHT: Mostly clear. Lows 60-67. Dew point approaches 60. Wind S up to 10 MPH.<\/p>\n\n\n\n
SUNDAY: Partly sunny. Late-day showers and thunderstorms possible. Highs 85-92 except cooler South Coast. Dew point rises through 60s. Wind SW 5-15 MPH.<\/p>\n\n\n\n
DAYS 6-10 (AUGUST 18-22)<\/p>\n\n\n\n
Fair, less humid August 18. Watch for a quick-moving disturbance to bring a shower chance August 19. A stretch of fair and pleasant weather follows mid to late next week, but during this time we’ll have to watch forecast Hurricane Erin likely making a re-curve off the US East Coast, more likely closer to Bermuda than the US. This would generate higher surf and larger ocean swells along the coast.<\/p>\n\n\n\n
DAYS 11-15 (AUGUST 23-27)<\/p>\n\n\n\n
Pattern indications are for a more northwesterly air flow in the region. During this period it would be a warmer start to the period, a mid-period disturbance with a shower \/ t-storm threat, and a late-period cooler shot.<\/p>\n","protected":false},"excerpt":{"rendered":"
