Spring weather is expected soon, and D.C.'s last frost could come this week.
Why it matters: After a chilly — sometimes frigid — start to spring, we're ready for fleeting mild weather before it's hot and humid again.
Zoom in: The median date of the last spring freeze in D.C. is March 29, which tracks with warming weather toward the end of this week.
That's earlier than some of our Southern cousins, e.g., Richmond, whose final average freeze is April 11.
The big picture: Median first fall frosts can be as early as January and as late as June, according to the Midwestern Regional Climate Center.
Growing seasons are getting longer, increasing up to 2.2 days on the West Coast every decade, which could allow farmers to diversify crops or have multiple harvests for specific crops.
