When will LaGuardia, JFK airport reopen? Winter weather advisory persists.

A snow storm that covered the Northeastern US Sunday managed to pack its biggest punch right on some the nation's most heavily trafficked airports.
LaGuardia, JFK, and Liberty airports were all still closed Monday morning as residents of the region began digging out from the big blizzard, which dropped as much as 30 inches in parts of the Northeast.
The storm left thousands of would-be travellers stuck right after Christmas holiday. The air-travel delays were matched with slow road conditions and sometimes-stalled rail traffic after the holiday weekend.
