Saturday's weather forecast is for sunny skies and 70 degree temperatures. Come on out to Roosevelt Island for the beautiful day and Magnolia Blossom Walk.

According to this 2009 post from Kimono dresser and blogger Beauty of Kimono:

I live in Roosevelt Island, just adjacent to Manhattan Island. There is a long row of cherry blossom trees, called as “Cherry Tree Walk”, in this island along East River. All the cherry blossom trees were presented from Japan.

Now light pinkish cherry blossoms, somei-yoshino, are blooming, but deep red ones, yae-zakura, near Queensboro Bridge have not yet come into flower.
The photo was taken when I go to see cherry blossoms last Sunday. Many people enjoyed looking at flowers, including more Japanese people than usual.
The cherry blossoms look like letters from Japan.
