Predict Your Own Thanksgiving-Snowstorm Travel Misery

The National Weather Service has an experimental new tool that shows the weather hazards along your journey, including predicted snow accumulations.
relates to Predict Your Own Thanksgiving-Snowstorm Travel Misery

A swollen storm with lousy timing is lurching toward the U.S. East Coast this Thanksgiving, and the implications for travel are worrying. With 1 to 3 inches of snow predicted for the I-95 corridor by Wednesday night (and up to 6 inches farther west), it's easy to gnaw fingernails over a possible commuter ant-crawl, littered with stalls, wrecks, airline delays, rage, and all the other fun ingredients of a mass-migration kerfuffle.

The National Weather Service office in Philadelphia says to "expect flight delays" and trouble on the roads, and is advising people finish their journeys "before 7 AM Wednesday morning." (Meaning if you haven't left yet, better get cracking now). "Conditions will be quickly deteriorating Wednesday evening," adds the agency's bureau in Gray, Maine. "We anticipate travel will be very difficult around that time." New York cuts right to the point with this: "THE SNOWFALL WILL SIGNIFICANTLY IMPACT HOLIDAY TRAVEL... MAKING DRIVING DANGEROUS AT TIMES."
