Could get even colder tonight.
Cherry blossoms begin sustaining damage when temperatures drop to 27 degrees (-2.8C). If temperatures drop to 24 degrees (-4.4C) or lower, up to 90 percent of exposed blossoms can be affected as their small white flowers turn brown and wilt.
Last night, temperatures dropped to the critical 27F mark and remained below that level all night. Indeed, there was a five-hour stretch at or below 24 degrees.
Horticulturists fear that continued cold could seal the blossom’s fate
Unfortunately, temperatures in Washington, D.C. are forecast to drop to 23F (-5C) tonight and to 24F tomorrow, according to AccuWeather.com.
