A major winter storm is headed for the D.C. area, just in time to disrupt holiday travel.

While the snow and ice created by a “bomb cyclone” is expected to stay further west, Fairfax County and the rest of the D.C. area are in for a downpour, according to the National Weather Service.

The NWS has already issued a Flood Watch for the region that’s set to be in effect from 11 a.m. tomorrow (Thursday) to 1 a.m. Friday (Dec. 23).

…FLOOD WATCH IN EFFECT FROM THURSDAY MORNING THROUGH LATE THURSDAY
NIGHT…

* WHAT…Flooding caused by excessive rainfall is possible.

* WHERE…DC and portions of Maryland and northern Virginia, including the following areas: District of Columbia. In Maryland, Anne Arundel, Cecil, Central and Southeast Howard, Central and Southeast Montgomery, Prince Georges, Southeast Harford and Southern Baltimore. In northern Virginia, Arlington/Falls Church/Alexandria, Fairfax and Prince William/Manassas/Manassas Park.

* WHEN…From Thursday morning through late Thursday night.

* IMPACTS…Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Flooding may occur in poor drainage and urban areas.

* ADDITIONAL DETAILS…
– Moderate rainfall is expected Thursday into Thursday evening, with rainfall totals of one to two inches. This may lead to isolated instances of flooding, especially in urban and poor drainage areas.

The Virginia Department of Transportation advises those planning to travel for Christmas to leave today instead of tomorrow, particularly if they’re going to be in the western half of the state.

“Crews have already begun pretreating and brining the roads and will begin deploying trucks early Thursday morning to treat roads as needed,” VDOT said in an advisory.

The department also warned that temperatures are expected to plummet into Friday, meaning fallen rain might refreeze into ice. Forecasts indicate this weekend may be the coldest Christmas in decades.

Updated at 8:05 p.m. — Fairfax County Public Schools will open two hours late tomorrow in response to the anticipated inclement weather.

Earlier: Fairfax County may get its first serious taste of winter weather for the season overnight.

A Winter Weather Advisory will be in place for the D.C. region from 1 a.m. to 1 p.m. tomorrow (Thursday), according to a National Weather Service alert issued this morning.

The NWS initially forecast that the anticipated freezing rain and ice could begin at 10 p.m. today but later revised the time frame.

“Wintry precipitation begins overnight and continues into Thursday morning,” the NWS said. “Warmer air should push in later Thursday morning into Thursday afternoon changing the precipitation to rain.”

More from the alert:

…WINTER WEATHER ADVISORY NOW IN EFFECT FROM 1 AM TO 1 PM EST THURSDAY…

* WHAT…Freezing rain expected. Total ice accumulations of a glaze to around one tenth of an inch. Highest ice amounts will be in the northern and western suburbs of Washington and Baltimore.

* WHERE…The Washington and Baltimore Metropolitan areas including the city of Baltimore and the District of Columbia as well as northeastern and central Maryland.

* WHEN…From 1 AM to 1 PM EST Thursday.

* IMPACTS…Difficult travel conditions are possible. The hazardous conditions will likely impact the morning commute on Thursday.

The Fairfax County Fire and Rescue Department warns that the rain could affect tomorrow’s morning commute, and Fairfax Connector says it will be monitoring the potential storm, advising that riders watch out for slippery or icy sidewalks.

The Virginia Department of Transportation began mobilizing crews yesterday to prepare roads for the wintry precipitation, noting that it has made some procedural adjustments in the hopes of avoiding a repeat of January’s I-95 shutdown.

The risk of ice tomorrow is expected to be highest further to the west in Virginia, where an Ice Storm Warning has been issued.

Temperatures could drop below freezing overnight in Fairfax County, continuing a cold streak that took hold earlier today (Wednesday).

The National Weather Service has issued a Freeze Warning that will take effect from 1 to 9 a.m. tomorrow (Thursday), stating that sub-freezing temperatures as low as 30 degrees Fahrenheit can be expected.

“Frost and freeze conditions will kill crops, other sensitive vegetation and possibly damage unprotected outdoor plumbing,” the NWS said.

Here’s more on what to do from the alert, which covers the D.C. area up past Hagerstown in Maryland:

Take steps now to protect tender plants from the cold. To prevent freezing and possible bursting of outdoor water pipes they should be wrapped, drained, or allowed to drip slowly. Those that have in-ground sprinkler systems should drain them and cover above-ground pipes to protect them from freezing.

According to the NWS forecast, this week is expected to close out with temperatures rising to highs in the upper-60s during the day on Saturday and Sunday (Oct. 22-23). Nights will see lows ranging from 37 degrees Thursday to 45 degrees on Saturday.

Fairfax County might get a little frosty overnight, in case the yellowing leaves outside weren’t a clear enough signal of autumn’s arrival.

The National Weather Service has issued a Frost Advisory for the D.C. area, warning that temperatures are expected to dip into the 30s, starting at 2 a.m. tomorrow (Wednesday).

…FROST ADVISORY IN EFFECT FROM 2 AM TO 9 AM EDT WEDNESDAY…

* WHAT…Temperatures around 33 to 36 degrees will result in frost formation.

* WHERE…Portions of central, northeast, northern and southern Maryland, The District of Columbia and northern Virginia.

* WHEN…From 2 AM to 9 AM EDT Wednesday.

* IMPACTS…Frost could kill sensitive outdoor vegetation if left uncovered.

“Take steps now to protect tender plants from the cold,” the NWS says.

As of 1:30 p.m., the NWS forecast for the county indicates that tomorrow will be mostly sunny, but frost may reemerge between 4 and 8 a.m. on Thursday (Oct. 20), when the low temperature will be 33 degrees Fahrenheit.

The chill comes from a cold front that has traveled southeast across the U.S. from as far away as northern Russia and the Arctic, the Capital Weather Gang reported Friday (Oct. 13).

Like the rest of the region, Fairfax County will be under a Heat Advisory from 11 a.m. to 8 p.m.

According to the National Weather Service’s alert, the heat index — which combines heat and humidity — could reach up to 106 degrees Fahrenheit, enough to potentially lead to heat-related illnesses.

Fortunately, the NWS has some advice:

Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances.

Take extra precautions if you work or spend time outside. When possible reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose fitting clothing when possible. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! Call 9 1 1.

Fairfax County has several facilities designated as cooling centers, including its two government centers, libraries, community centers, rec centers, and emergency shelters for those experiencing homelessness.

“Resting for just two hours in air conditioning can significantly reduce heat-related illnesses,” the county said in an emergency information blog post.

Fairfax County and areas nearby are under a Severe Thunderstorm Watch this evening.

The National Weather Service issued a Flood Watch earlier today (Monday), cautioning flooding may occur this evening, and a Severe Thunderstorm Watch is in effect until 10 p.m.

“Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations,” the Flood Watch reads. “Afternoon to evening showers and thunderstorms may produce very heavy rainfall capable of flash flooding. This could include multiple rounds of storms which would enhance the flood risk. Rainfall rates may reach 1 to 2 inches per hour, locally higher in spots. The D.C. and Baltimore metros will be the most susceptible given recent heavy rainfall the past couple of weeks.”

The National Weather Service advises residents to monitor forecasts and be prepared in case of flash floods.
