DAYS 1-5 (JULY 20-24)<\/p>\n\n\n\n
Yesterday was the pick of the weekend for the vast majority of people. Today is the pick of the weekend if you like higher humidity, less sun, and at least the chance of a thunderstorm. (And not that this next statement is relevant to the forecast, but I pick both days – haha!) … But writing in favor of the likings of the “weather majority”, the high pressure area that brought us very nice weather yesterday has departed and today we’ll be dealing with an area of low pressure passing to our northwest, bringing us higher humidity and some unsettled weather. Our wet weather \/ storm chances will be limited though, and for any given location most of today will be rain-free. A warm front passing by this morning brings the best chance of showers to the South Coast and Cape Cod, but a lot of this will stay over water just to the south, and the last of it should exit that region by noon. Otherwise, a cloud canopy covers much of the region to start the day, but later this morning into this afternoon a clearing trend will allow for a fair amount of sunshine – with that sun also reaching southeastern areas later. This means that your Sunday turns quite nice, despite the higher humidity, because a ventilating breeze will accompany the increase in sunshine too. Meanwhile, a cold front will approach from the northwest later in the day, and across NY and northern New England we’ll see showers and thunderstorms pop up and eventually organize into a broken line (perhaps 2 lines as some short range guidance has hinted at that). For the majority of the WHW forecast area though I am expecting the impact to be from one broken line of showers and storms passing through from northwest to southeast generally from 3:00 p.m. to 9:00 p.m. Note! That 6-hour window does not mean you see rain and thunder for 6 hours. It means that during that 6 hour window, the front and its accompanying convective activity move from northwest to southeast across the region. Pick any given location and a shower or thunderstorm would visit for 30 to 90 minutes, in general – with a tendency to be more to the shorter duration of that range. Additional, a broken line of convection can have gaps in it which means that some areas can be grazed or even entirely missed – seeing little or nothing. This is the nature of convective activity, so monitor radar if you have plans in the time window of concern. For areas that do see the stronger storms, expect brief torrential rain, potentially frequent lightning, possible small hail, and the biggest threat being strong, potentially damaging wind gusts. All of this ends by late evening as the front clears the coast. Then cue the Canadian air mass which moves in for Monday and Tuesday as high pressure builds southeastward into our region. Temperatures fall below normal during this time with very dry air as well. Heading to midweek, Wednesday and Thursday will feature fair weather and a warming trend as high pressure slides offshore.<\/p>\n\n\n\n

DAYS 6-10 (JULY 25-29)<\/p>\n\n\n\n
Brief heat \/ humidity spike July 25 with late-day t-storm potential from approaching cold front. Early look at the July 26-27 weekend shows fair weather July 26 and unsettled weather with a disturbance on July 27, but this far in advance timing is not super-certain. Fair, dry weather would follow that later in the period.<\/p>\n\n\n\n
DAYS 11-15 (JULY 30 \u2013 AUGUST 3)<\/p>\n\n\n\n
West to northwest air flow east of a central US ridge, with trough in Atlantic Canada. This pattern is dry much of the time, brief shower \/ t-storm chances from passing disturbances, and features variable temperatures with no sustained heat.<\/p>\n","protected":false},"excerpt":{"rendered":"
