Ice Accretion Amounts to Fall Below Ice Storm Warning Criteria, But Still Will Cause Travel Troubles Tuesday Night

    Ice Storm Warnings in most of the Northeast United States require a half inch of ice accretion - that is, freezing rain resulting in a glaze one-half inch thick or greater - and that amount of ice is not expected overnight Tuesday night.  That said, Freezing Rain Advisories are issued anytime freezing rain is expected to leave a glaze on area surfaces and roadways, which is precisely what's expected overnight.  I expect at least slight icing as far south as Northern Connecticut and Central Massachusetts, where temperatures are below freezing as of this early evening writing, with greatest ice accretion amounts to be approximately .20"-.25", with highest amounts found around the White Mountain National Forest, nearby Mount Washington Valley, and Oxford County, Maine.  These amounts will surely be enough to cause substantial overnight travel troubles with ice covered untreated roads, but also may result in an isolated power outage.  Temperatures will warm sufficiently above freezing early Wednesday morning to change all areas of freezing rain over to plain rain.
