AUGUST 15-19 (DAYS 1-5)
Discussion…
Our weather here in southeastern New England this weekend and Monday will be influenced by high pressure to the north and a couple waves of low pressure moving to the east and passing south of the region, the first of which has become our latest tropical system of the season, Tropical Storm Kyle, which is destined to pass harmlessly southeast of the region. The second wave of low pressure will not develop into a tropical system and while passing by a little closer than the first one, it will still be too far south to bring any appreciable rainfall to the region, with mainly dry weather being dominant. The most significant impacts of this synoptic set-up will be cooler weather, lower humidity (though not too dry), a noticeable breeze from the northeast to east, and some fairly rough surf along the shoreline, especially east-facing coastal areas, where boating, surfing, and swimming should be done with extreme caution. It won’t be the greatest beach weekend by typical standards anyway. Looking a bit ahead, this pattern lets go by Tuesday when a weak cold front crosses the region during the morning and midday with a threat of a shower or thunderstorm and a shot of muggy air. This front moves offshore during the day and drier air arrives. By Wednesday, that front is dissipating offshore while high pressure builds in with nice mid August summer weather.

High pressure builds in from eastern Canada with mainly dry weather. Temperatures start seasonable with humidity in check then a trend to warmer/hotter and higher humidity begins.
