Clouds and mid 40s greet Washington, D.C., this morning, with only a slim chance of a brief sprinkle before skies clear and a high near 55°F later Monday, April 20. Northwest winds will crank up this afternoon, with gusts into the 20s that will make the commute feel raw. Two local hazards are on the table: an elevated fire weather concern for drier inland pockets today and a Freeze Warning overnight into Tuesday morning that could harm tender plants.
Afternoon Winds Pick Up
Northwest winds will steady at 8 to 13 mph this afternoon with gusts around 20 to 25 mph in the city and stronger bursts over hills and ridges. Dry air behind the front has lowered humidity across inland areas, raising fire spread potential for fields and brush in outlying valleys and the Piedmont. Take care with any outdoor burning or power equipment use this afternoon and keep a quick response plan in mind.
Protect Plants And Pipes
Bring potted plants inside and cover vulnerable garden beds before sunset, since low lying neighborhoods will be coldest. Disconnect and drain garden hoses and insulate exposed faucets to avoid freeze damage to irrigation lines and outdoor plumbing. These small steps can prevent the most common household and garden losses from a brief freeze.
Overnight Freeze Warning
The National Weather Service has issued a Freeze Warning for much of the region from 2 AM to 10 AM on Tuesday, April 21, with widespread frost expected after about 2 AM and nighttime lows near 32°F in many suburbs, the National Weather Service notes. The NWS warns that "frost and freeze conditions could kill crops, other sensitive vegetation and possibly damage unprotected outdoor plumbing."

Commute And Outdoor Plans
Roads should stay mostly dry today, but gusty northwest winds could slow bike and pedestrian commutes and make it feel colder than the thermometer reads. If you have errands on Tuesday morning, plan for patchy frost on cars and sidewalks and give yourself extra time to clear windshields. If you can, shift outdoor morning plans to the afternoon for a more comfortable setup.
Midweek Warm Up And Storm Risk
Temperatures rebound midweek, with highs climbing into the low to mid 70s by Wednesday, April 22, and into the upper 70s to around 80 by Thursday and Friday, though the warming brings an uptick in shower and thunderstorm chances. Keep an eye on forecasts if you have outdoor events later in the week, since afternoon windows look best for outdoor work. We will update readers if any higher severe weather threat develops.
