SUMMARY...Blizzard conditions are beginning across portions of

Snowfall rates up to 2 to 3 inches per hour are expected late this

beyond this afternoon. Some locations are forecast to receive over 2
feet of snow with persistent blizzard to near blizzard strength
winds and visibilities expected for the next 24 to 48 hours. This is
expected to cause extreme impacts across the region.
