LIVE: Dangerous Snow Squalls Precede New England Blizzard

Blinding snow squalls have led to dangerous travel conditions across the Ohio Valley and Northeast this Valentine's Day.

Numerous accidents on major thoroughfares have already been reported across parts of Indiana, Ohio, western New York and Southern Ontario. Speed limit reductions have also been put in effect.

"Motorists should be alert for rapidly changing weather conditions that include a sudden drop in visibility, strong winds and a rapid freeze-up," AccuWeather.com Senior Meteorologist Alex Sosnowski said.

In New England, the tranquil conditions with spotty light snow from Saturday afternoon will transition to dangerous travel as winds and snow increase with extensive blowing and drifting of snow and plummeting temperatures later at night, Sosnowski added.
