The dream of a white Christmas could be a reality this year. AccuWeather.com meterologist Heather Zehr says rain will change over to snow later today, with a coating to an inch possible overnight. Don’t expect it to stick around for very long, though. Between the sun and a forecast high temperature of 37, Zehr says it will probably be gone by noon or so. The sun will be back out Friday, but more snow mixed with rain is possible on Saturday.
