There will be a chill in the air tomorrow (Tuesday) morning — and it’s not just because Halloween will only be a week away.
A Frost Advisory is set to take effect for portions of Maryland and Virginia, including Fairfax County, from 2-10 a.m., the National Weather Service announced today.
“Temperatures as low as 33 will result in frost formation,” the NWS said, warning that the frost could be fatal to sensitive outdoor vegetation.
The agency advises covering plants or taking other steps to protect them from the cold.
For Fairfax County, the NWS is currently forecasting “patchy frost” for tomorrow, likely between 4 and 9 a.m. Temperatures could range from a low of 35 degrees to a high of 67.
However, a warming trend is anticipated later in the week, according to the NWS and the Washington Post’s Capital Weather Gang. The forecast shows temperatures climbing to a high of 78 degrees on Friday (Oct. 27).
Looking into the slightly more distant future, the NWS projects that the D.C. area will get another mild winter, though emerging El Niño weather patterns could bring the snowstorm that was absent last year, according to the Capital Weather Gang.

Updated at 4:05 p.m. — A Coastal Flood Advisory issued for parts of Northern Virginia, including Fairfax County, will now take effect at midnight, earlier than initially anticipated, the National Weather Service says.
Earlier: It’s going to be a cold and rainy weekend in Fairfax County, thanks to Tropical Storm Ophelia.
Tracking to make landfall in North Carolina today (Friday), the storm is expected to reach Northern Virginia tonight with “heavy rain, high winds, and cool temperatures” continuing into Sunday (Sept. 24) morning, according to the Fairfax County Department of Emergency Management.
“Locally, [the National Weather Service] expects 2-4 inches of rain throughout the weekend,” the county said in a post on its emergency information blog. “Since the precipitation will be spread across the weekend, flooding is not a major concern but could cause some localized flooding issues. Wind speeds will gradually increase, peaking around 40 mph on Saturday.”
The storm has already affected some major events, prompting cancellations of the popular Reston Multicultural Festival, the inaugural Fairfax Fiesta in Tysons and a kick-off for National Public Lands Day in Annandale. Other events, like Fairfax City’s Fiesta Fairfax, have been relocated indoors.

The annual festival, which is organized by Reston Community Center, will not be rescheduled. With a tropical storm projected to make landfall in the mid-Atlantic, high winds, cool temperatures and heavy rain are expected from around 11 p.m. Friday through Sunday morning.
“With artists, vendors, community organizations, and event staff and volunteers coming from various areas affected by this tropical storm, organizers do not want to put people at risk of injury in trying to reach or attend the festival,” RCC said in a statement. “People are urged to stay off the roads on Saturday. This annual event is cherished by the community, and event planners appreciate everyone’s understanding that people’s safety is their highest priority.”
RCC said it was thankful to Reston Town Center Association and host BXP for their help in coordinating the event. Reston Association also provided support.
This year would have been the organization’s largest festival to date, with additional performance stages and strategic partnerships with national organizations.
“The partnership among these civic, nonprofit and business organizations allowed for the most ambitious Reston Multicultural Festival plan ever. All partners are looking forward to 2024 and doing it again under sunnier skies,” the organization wrote.
A Darden and Friends concert will still take place as scheduled at 5:30 p.m. tomorrow (Friday) in the Pavilion at Reston Town Center, according to RCC.

It’s another stifling day in Fairfax County with no immediate relief in sight.
As of 11 a.m., temperatures at Fort Belvoir had reached 90 degrees, but thanks to 65% humidity, it likely feels closer to 103 degrees outside, according to the National Weather Service.

The Fairfax County government shared a reminder of the symptoms of heat exhaustion or stroke, which can include fainting, dizziness, muscle cramps, headaches, nausea and either excessive or no sweating.
“During hot and humid weather, your body’s ability to cool itself is challenged in ways you may not expect,” the county said.

The county has also recently bolstered its response to extreme heat events by improving its process for alerting unsheltered residents and offering free Fairfax Connector bus passes to cooling centers.
