March could be colder than February in D.C., with snow possible mid-month.

The progression to spring will probably be quite slow this year.

After an exceptionally warm January and February, one might expect to leap ahead into spring during March. But not this time. The evolving weather patterns are conspiring to deliver a parting shot from winter.

We project normal to below normal March temperatures — averaging 45 to 48 degrees compared with the norm of 47.6 degrees. March could well be colder than February for the first time since 2018 and 2017. Precipitation should be near to above normal with 3.25 to 4.5 inches of rain and melted snow (the norm is 3.5 inches). Between 0.5 and 4 inches of snow is a reasonable expectation (the March norm is 2 inches), which is more than we’ve seen the entire winter so far.

While March will start on the mild side this week, we are monitoring changes in the Pacific Ocean and the Arctic that should help a colder pattern become established during the month’s second week. Also, the La Niña event — which tends to limit precipitation — is weakening, which should increase rain and snow chances into spring after a relatively dry January and February.'>>>
