As astronomical spring begins at 10: 46 a. m. ET on Friday, a noticeable warming trend arrives alongside what weather forecasters describe as a fifth straight rainy weekend across Greater Boston and much of New England. Morning commutes will be milder than earlier in the week, but afternoon and evening systems promise steady showers and soggy evening plans for the region.
Spring: Warming Mornings, Soggy Commutes
The first day of spring brings a shift from the cold mornings that dominated the week. Commute temperatures are expected in the low 30s rather than the 20s, with skies partly to mostly sunny and a subtle southerly flow helping boost readings. By afternoon, a modestly potent storm will push into New England from the west. Light to steady showers are forecast to reach Boston between 4 p. m. and 8 p. m. ET, creating the prospect of a wet commute and evening for many. Highs on Friday should climb into the low to mid-50s away from immediate coastal areas, while coastlines will remain cooler in the mid- to upper-40s.
Weekend Rain Streak: Friday Night Through Sunday
The developing rain streak will produce two systems that bookend the weekend. Friday night’s storm is expected to exit faster than recent trends, clearing the way for a largely pleasant Saturday across most of New England. There may be a few scattered showers lingering early Saturday morning near Boston and the coast, but conditions should clear relatively quickly with a mix of sun and clouds.
Sunday brings a similar system pushing in from the west during the afternoon. With a warm front arriving, widespread rain is likely across Southern New England; Central and Northern Maine will be the most likely areas to see a wintry mix or snow. Scattered showers should persist from Sunday afternoon into the start of Monday, extending the streak of weekend precipitation for the region.
Impacts Across Northern and Southern New England
Not all areas will experience the weekend the same way. Northern portions of New England, generally north of Bennington, Vt., Concord, N. H., and Portland, Maine, face the possibility of a wintry mix or plain snow as temperatures fall overnight and the storm cores pass after sunset. Between Friday night and Sunday evening or night, northern communities may see 2 to 5 inches of snow, with a few higher-elevation spots reaching 5 to 8 inches by Monday morning. Southern New England should expect mainly rain, with both systems producing about an inch of precipitation on aggregate.
Temperatures will reflect that split: highs on Sunday will be in the upper 40s to low 50s across Southern New England, while northern areas will be held to the low 40s. Coastal cooling from cold waters will keep immediate shorelines several degrees cooler than inland locales.
Expert Perspectives and Practical Advice
The weekend outlook emphasizes the pattern change: morning high pressure and southerly flow producing milder starts, followed by quick-moving systems from the west that deliver steady evening rain. For planning, Saturday night offers the best window for outdoor activities; both Friday and Sunday evenings are described as the soggiest. Travelers and residents in northern high terrain should track accumulating snow amounts overnight Sunday into Monday morning.
With spring now underway and the rain streak extending into its fifth consecutive weekend, communities face a mix of milder daytime conditions and repeated wet periods. How will residents and infrastructure adapt if this pattern persists into the season?
