DAYS 1-5 (SEPTEMBER 10-14)…
Let’s play warm front / cold front! Today is warm front day. The front that slogged through as a cold front on Friday and barely dropped the humidity while allowing it to get quite hot was technically labeled as a cold front, but did not do much in the way of delivering any refreshing air, nor did it bring anything resembling beneficial rain. Our warm front / cold front combination this weekend may do slightly better in the rain department, but stress the word “slightly” here. Again, we’ll not receive a beneficial rain over the entire region. After a warm front that just brings a few scattered showers as it pushes through today, a cold front coming through at the “wrong time”, i.e., before maximum heating, on Sunday will muster a few showers and downpours, but again leave many areas high and dry. Once this front gets offshore Sunday afternoon, drier air will arrive in more force along with fair weather that lasts through Tuesday, courtesy of high pressure. As this high slips to the south Tuesday and Wednesday, a warm-up will ensue, but just as it’s about to get that late-season hot/humid feel, it will be cut off at the pass later Wednesday by a stronger cold front from the north, which will bring a shower and thunderstorm threat.
TODAY: Mostly cloudy to partly sunny – greatest chance of sunshine south of Boston. Isolated to scattered showers but most areas dry. Increasing humidity. Highs 74-81. Wind E to SE up to 10 MPH.
TONIGHT: Partly to mostly cloudy. Patchy fog. Isolated showers overnight. Humid. Lows 61-68. Wind SE to S up to 15 MPH.
SUNDAY: Variably cloudy through midday with isolated to scattered showers and thunderstorms including a few possible downpours. Clearing trend west to east afternoon. Decreasing humidity. Highs 76-83. Wind S to SW up to 20 MPH with higher gusts possible.
SUNDAY NIGHT: Mostly clear. Lows 53-60, coolest in southern NH and north central MA. Wind W up to 15 MPH with higher gusts.
MONDAY: Mostly sunny. Highs 75-82. Wind N up to 10 MPH becoming variable.
TUESDAY: Partly cloudy. Lows 55-62. Highs 77-84.
WEDNESDAY: Variably cloudy. Risk of midday and afternoon showers/thunderstorms. More humid. Lows 60-68. Highs 78-86.

Shot of cooler/drier air Thursday September 15 with fair weather. High pressure will be in control September 16-18 with fair weather, cool mornings September 16-17, slow warming trend each afternoon through September 18. By September 19 a shot of heat/humidity precedes the next front and there may be a shower/t-storm threat – of course timing uncertain this far in advance.
