The forecast models are trending a bit faster with the change over to snow and sleet this afternoon across the interstate 95 corridor. Don’t be surprised to see Winter Weather Advisories extended south and east to cover more of the immediate Metropolitan Area for the afternoon hours given the 1″ at rush hour rule.
