At Providence, two periods of precipitation, the first Fri until 11:00am and the second Sat (Christmas Day) 4:00am-11:00pm, could put a tiny amount of snow on the ground at some point.
A Winter Weather Advisory has been posted for Sat 1:00-10:00am for possible freezing rain and sleet that could cause slippery roads and ice accretion on trees and power lines.
The first period is likely to be snow but little accumulation is expected, at most a fraction of an inch. The second period could begin as snow or sleet, but is expected to be all rain by Sat 9:00am, likely ending Sat night but possibly persisting into Sun midday.
If there is a ground covering of snow on Sat morning around 7:00am that qualifies as a traditional “Write Christmas,” but temperatures above freezing Fri afternoon likely will melt any earlier accumulation.
The median accumulation forecast in the city is 0.1 in, with probabilities 27% for at least 0.1 in and near 0% for 1 in.
