Extreme weather highlights the final day of winter.
The heatwave that has swept across much of the country arrived at the end of what has been the fourth warmest winter ever.
The National Weather Service says in the last week alone at least 400 places have recorded record highs.
In New Jersey the unseasonably warm weather has led to an early cherry blossom season, but spring is not blossoming everywhere just yet.
A late snow storm has put a freeze on New Mexico and Arizona.
Shovels and plows are working overtime in some areas.
The conditions were so severe Interstate 40 had to be shut down.
Still, across much of the country the gateway to spring is now wide open.
Most are hopeful the mild conditions linger before the dog days of summer get here.
