WASHINGTON (WUSA) -- Tuesday, the National Park Service pushed back the peak bloom period for D.C.'s cherry blossoms to April 3 through April 6. 

Officials originally estimated the peak bloom period would be March 26 through March 30.

According to the NPS website, "The Peak Bloom Date is defined as the day in which 70 percent of the blossoms of the Yoshino Cherry (Prunus x yedoensis) trees are open. The date when the Yoshino cherry blossoms reach peak bloom varies from year to year, depending on weather conditions. Cherry Blossom Festival dates are set based on the average date of blooming (April 4), but nature is not always cooperative. Unseasonably warm and/or cool temperatures have resulted in the Yoshino cherries reaching peak bloom as early as March 15 (1990) and as late as April 18 (1958)."

NPS later explained in a statement that the date was changed because "colder temperatures, especially nighttime lows in the 30s, have slowed development of the budding."
