DAYS 1-5 (AUGUST 31 – SEPTEMBER 4)
The final day of August will be one of the nicer days of the summer with a sun/cloud mix, lowering humidity, but still warm, as a weak area of high pressure moves in. This high pressure area will move away by early Wednesday and we will then eye the approach of the low pressure area that was once Hurricane Ida from the southwest. As this area of low pressure and its associated moisture stretches out along a frontal boundary as it moves into and through the region Wednesday night into Thursday, it becomes more difficult to pinpoint where the axis of heaviest rainfall will be. Similar to a winter system there can be a rather sharp drop off in precipitation gradient, and even the timing is still a little in question, with some guidance taking the system out of here rather quickly Thursday afternoon while other models linger the rainfall into Thursday evening. Currently, my leaning is slightly faster on the timing, but still a significant rainfall (over 1 inch and up to a few inches of rain) especially in the I-95 & I-90 belts south and east. Tweaks to come if needed. Drier air arrives Friday but still have to watch for a pop up shower due to marginal instability being worked on by daytime heating. High pressure brings great weather Saturday to start off Labor Day Weekend.
TODAY: Partly cloudy. Highs 80-87. Dew point falling to near 60. Wind WNW 5-15 MPH.
TONIGHT: Mostly clear. Lows 60-67. Dew point upper 50s. Wind N up to 10 MPH.
WEDNESDAY: Increasing clouds. Highs 70-77. Dew point near 60. Wind E up to 10 MPH.
WEDNESDAY NIGHT: Cloudy. Rain likely. Areas of fog. Lows 60-67. Dew point lower to middle 60s. Wind SE to E 5-15 MPH.
THURSDAY: Cloudy with rain likely, tapering off late day when clouds may break especially northwest of Boston. Areas of fog through midday. Highs 65-72. Dew point lower to middle 60s. Wind E 5-15 MPH shifting to N.
THURSDAY NIGHT: Partial clearing. Areas of fog. Any lingering rain ends. Lows 58-65. Dew point lower 60s to upper 50s. Wind N to NW up to 10 MPH.
FRIDAY: Partly cloudy. Slight chance of isolated showers. Highs 71-78. Dew point near 60. Wind NW up to 10 MPH.
FRIDAY NIGHT: Partly cloudy. Fog patches forming interior lower elevations. Lows 56-63. Dew point middle 50s. Wind NW under 10 MPH.
SATURDAY: Mostly sunny. Highs 70-77. Dew point 50s. Wind NW 5-15 MPH.
DAYS 6-10 (SEPTEMBER 5-9)
Sunday of Labor Day Weekend (Sep 5) will be fair, mild, and a tiny bit more humid as high pressure shifts and the wind blows from the southwest. Labor Day Monday features warm and humid weather with a chance of passing showers and thunderstorms as a cold front approaches the region. Trend is to drier/cooler for the middle of next week but the transition may be a little delayed to get there with one more disturbance to come through. Will keep an eye on that.
DAYS 11-15 (SEPTEMBER 10-14)
Cool/dry interlude early period, warming up again mid to late period as a larger area of high pressure drifts from northwest to southeast across the Northeast. A period of showers may accompany the shift from cooler to warmer weather.
