THE WATER

A stalling nor'easter brings 1 to 3 inches of rain from Philadelphia to Boston. The slight excessive-rain risk is highest over Long Island, Rhode Island and eastern Massachusetts. Another 1 to 2.5 inches is forecast on Sunday, and the rain may worsen coastal flooding. A second slight risk covers eastern Nebraska and Iowa.

WHAT THEY'RE SAYING

Forecasters anticipate a nor'easter that will bring several inches of rain along the coast from the mid-Atlantic into New England, with the added possibility of heavy downpours and coastal flooding in New England as the low develops. This lines up closely with the outlook for a stalling system that produces one to three inches across the corridor, though the comments underscore how amounts could concentrate near the shore and extend the wet period. No major departures from the main forecast appear in these assessments.
