Clouds and rain ahead
After a long stretch of clear, calm weather for our area, chances for rain will increase in the coming days. A broad high pressure parked offshore in the northern Atlantic will finally lose its grip and allow more unsettled weather to traverse New England. The high sustained a light easterly to southeasterly breeze during the past week, pushing in cool air off the Atlantic and limiting daytime maximum temperatures. This pattern will continue today, before a weak low pressure center to our south brings warmer and moister air. This low will be sluggish, producing occasional showers through this week and keeping skies cloudy. However it will provide a southerly flow that should allow temperatures to rise into the upper 60s°F (19–20°C).
The best chances for rain will come late Wednesday into Thursday as some thunderstorm activity forming near the low reaches southeastern New England. Intermittent showers will last into the weekend, until a broad high pressure builds over the eastern U.S. early next week.
