News Summary
Boston is poised for a weekend of pleasant weather with a significant drop in humidity, offering residents a break from the recent heat. Friday will see highs in the upper 70s, while Saturday promises sunny skies and temperatures reaching the low 80s. However, Sunday will bring changes with higher humidity and temperatures moving into the low 90s. Residents are advised to stay informed as Tropical Storm Erin strengthens in the Atlantic, potentially affecting the weather next week.
Boston is set to enjoy a weekend of mostly dry weather and a significant drop in humidity, making for a refreshing break from the recent sultry conditions that have been likened to Florida’s climate. Following a humid Thursday characterized by dew points in the low 70s, the upcoming days will see high pressure move into the region, creating clearer skies and more comfortable temperatures.
Starting with Friday’s forecast, the day is expected to be pleasant with mostly sunny skies. Afternoon highs will reach the upper 70s in Greater Boston and potentially hit the 80s inland. The morning will bring a notable drop in dew points, which will range in the low 60s and may fall into the upper 50s by the evening. As night falls, temperatures are expected to settle in the upper 60s to low 70s.
Throughout Friday, partly to mostly sunny conditions will prevail with winds picking up to 10 to 15 miles per hour, adding a gentle breeze to the atmosphere. These favorable conditions are anticipated to provide relief from the high humidity experienced earlier in the week.
Saturday is forecasted to be the highlight of the weekend, boasting mostly sunny skies and high temperatures reaching into the low 80s across the region. Coastal areas are likely to see milder temperatures in the mid to upper 70s, while inland locales could experience the warmer conditions well into the 80s.
In contrast, Sunday will bring a shift in weather patterns as a cold front approaches. This change is expected to usher in higher humidity levels and increased temperatures, pushing highs into the low 90s in Greater Boston and upper 80s along the North and South Shores. Morning conditions might remain mostly sunny, but the afternoon is likely to bring cloud cover and humidity, possibly resulting in scattered showers later in the day.
In the wider New England area, Central and Western Massachusetts can expect highs in the low to mid-80s on Saturday, with increases to the low 90s on Sunday, alongside chances of scattered showers. New Hampshire will remain mild with expected temperatures in the low to mid-80s on Saturday, rising to the upper 80s and low 90s by Sunday. Vermont and Maine will similarly see highs in the 70s to low 80s on Saturday, transitioning into cloudier conditions by Sunday with some prospects for sprinkles.
In the background of this weekend’s weather forecast, Boston has already seen an impressive 18 days of 90-degree weather this year, surpassing the typical annual average of 14 days. Residents are advised to pay attention to the forecast as Tropical Storm Erin is currently present in the Atlantic and is expected to strengthen. Although Erin does not pose an immediate threat to land, it may generate hazardous rip currents along New England beaches next week.
The upcoming weekend offers Boston and the rest of New England a reprieve from the heat and humidity, with Saturday boasting the best conditions. However, as the week wraps up, the potential for returning heat and humidity reminds residents that summer weather can still be unpredictable.
In conclusion, individuals planning their weekend activities can look forward to enjoyable weather, with the aforementioned shifts in temperatures and conditions throughout the region throughout Friday, Saturday, and Sunday.
