Several inches of snow possible tomorrow

After temperatures got up to 55°F in Boston this past weekend, our area will see accumulating snowfall tomorrow for the second time in three days. While yesterday’s all-day snow event was relatively harmless — leaving behind less than an inch of accumulation — tomorrow’s event is expected to be more significant. At the time of this writing, the National Weather Service had issued a Winter Storm Watch for “late Tuesday night through Wednesday afternoon,” forecasting the possibility of 6 to 10 inches of snow accumulation.

However, snowfall totals for this storm remain relatively uncertain, as they will be highly dependent on the exact track of the storm. The low pressure center, which has yet to develop, will pass just to the south of New England, spreading heavy precipitation across Connecticut, Massachusetts, and Rhode Island. A southerly perturbation to the storm’s track could push the areas of heaviest precipitation away from Boston, while a northerly perturbation would bring warmer temperatures, introducing the possibility for a wintry mix of snow, rain, and ice. Should the areas of heaviest precipitation fall over the Boston area, the Institute could experience heavy snowfall rates of 2 inches per hour during the midday tomorrow.
