Significant Weather Outlook: Sunday, March 22, 2026 3 PM
Significant Weather Weekly Outlook
Since the author will likely be away this Monday (March 23), this weekly significant weather outlook is being issued a day ahead of time. There are no major storms expected this coming week, but there are a series of light to moderate precipitation events in store for southern New England.
Tonight through Monday Night
A quasi-stationary front across central New England will slip south late tonight (Sunday night) while a wave of low pressure moves along the front near or a little south of the New England south coast on Monday. Rain and snow in association with this relatively weak low pressure system will fall across much of southern New England late tonight through Monday morning, lingering into the afternoon over eastern MA. A period of light to moderate wet snow could produce 1 to 3 inches of snow on grassy surfaces, especially over elevated terrain areas. Most roads will be just wet, although some slushy road surfaces are possible with any bursts of somewhat heavier precipitation during Monday morning. There may be some minor delays during the Monday morning commute, especially in portions of central MA.
Some upper-level energy passing over an inverted surface trough of low pressure may produce a period of snow showers Monday evening, most likely across eastern MA. Although more confined areal-wise, this could produce some locally slick spots along some road surfaces in eastern MA (east of Worcester) as temperatures drop Monday evening. These snow showers could produce localized 1 to 2-inch accumulations, most likely in parts of northeast MA. These inverted surface troughs tend to be difficult to predict and so confidence is low. Nevertheless, all numerical prediction models at least hint at this feature for Monday evening.
Rest of the Week
The rest of the week looks to feature another series of precipitation events late in the week (Thursday/Friday time frame with perhaps the most significant being Thursday night into Friday morning). Across southern New England, the precipitation is expected to be mainly in the form of rain possibly mixed with wet snow. Some minor accumulations may be possible Thursday night or Friday over the higher terrain north of the Mass Pike.
Next Message
The next message will likely be the scheduled weekly significant weather outlook planned to be issued next Monday March 30 unless a weather event this coming week should show the potential to produce significant hazardous weather.
