DAYS 1-5 (AUGUST 29 – SEPTEMBER 2)
Showers that I did not forecast very well got into the area last night wetting down some Saturday evening plans – not one of my better short-term forecasts! Ah well! Those have moved out for now and we are left with a mainly cloudy Sunday as a warm front approaches the region, and I do think any shower activity today will be limited to this evening and tonight as the front moves through. This will introduce warmer and humid air to the region for Monday, a day which carries a shower and thunderstorm chance as we will be in a smaller warm wedge of air between that warm front and an approaching cold front. We’ll have to keep an eye on the situation tomorrow as a few strong or severe thunderstorms are possible. The cells should be isolated to scattered during the day with the possibility of a more organized broken or perhaps solid line crossing at least parts of the region from late afternoon into evening. This front should clear the region by early Tuesday, a day that will still be warm but less humid to end of the month of August. The first couple of days of September will find our attention on the remains of Hurricane Ida (making landfall today as a dangerous category 4 hurricane on the Louisiana coast). The remains should have an impact with some rainfall in our area Wednesday into Thursday, the timing and exact orientation of which still will have to be pinned down. Early estimate: Wednesday PM to Thursday AM, heaviest in southeastern areas, but don’t lock this in yet. Anything from a shift northward with heaviest rain north and showery weather here to a complete miss to the south remains on the table.
TODAY: Mostly cloudy. Scattered showers mainly south and west of Boston by later in the day. Highs 70-77, coolest eastern coastal areas. Dew point upper 50s to lower 60s. Wind SE to S up to 10 MPH.
TONIGHT: Mostly cloudy. Scattered showers. Areas of fog. Lows 62-69. Dew point lower to middle 60s. Wind SE up to 10 MPH shifting to SW.
MONDAY: Partly sunny. Chance of showers and thunderstorms. Highs 85-92. Dew point upper 60s to lower 70s. Wind SW 5-15 MPH.
MONDAY NIGHT: Variably cloudy. Chance of showers and thunderstorms. Areas of fog. Lows 65-72. Dew point middle to lower 60s. Wind variable 5-15 MPH.
TUESDAY: Sun and passing clouds. Highs 80-87. Dew point falling to upper 50s. Wind NW 5-15 MPH.
TUESDAY NIGHT: Mostly clear. Lows 60-67. Dew point upper 50s. Wind variable up to 10 MPH.
WEDNESDAY: Increasing clouds. Rain chances go up as the day goes on. Highs 70-77. Dew point rising to lower 60s. Wind SE up to 10 MPH.
WEDNESDAY NIGHT: Cloudy. Rain likely. Chance of thunderstorms. Areas of fog. Lows 63-70. Dew point lower to middle 60s. Wind variable 5-15 MPH, higher gusts.
THURSDAY: Mostly cloudy with a chance of showers in the morning. Partly cloudy in the afternoon. Highs 73-80. Dew point 60s. Wind variable 5-15 MPH, higher gusts possible.
DAYS 6-10 (SEPTEMBER 3-7)
High pressure should bring dry weather and a warming trend September 3-5 though a brief interruption of clouds and a shower threat may occur between late September 4 and early September 5 as humidity increases. Frontal system interacts with higher humidity bringing a shower chance later in the period, but not completely sure on timing this far out. Continued early call on Labor Day Weekend (September 4-6) is not too bad overall.
DAYS 11-15 (SEPTEMBER 8-12)
Cooler/drier trend early to mid period, warm-up late period. Mostly dry weather is expected.
