Snow moves away from DC region, but roads could refreeze

The fast-moving winter snowstorm that blasted the D.C. region Sunday left residual precipitation that could refreeze, making for a potentially messy Monday morning commute.

Plummeting temperatures could have caused standing water and slush on area roadways to refreeze, leading to icy driving conditions Monday, according to Storm Team4 meteorologist Mike Stinneford.

He said Monday will be a cold day with high temperatures “only in the 30s.” There could be some travel issues early Tuesday too, as a “light wintry mix” moves in, Stinneford said.

He warned that the D.C. region could experience another chance of snow and ice late Wednesday night into Thursday.

Temperatures throughout the week will remain in the 30s and 40s, Stinneford said.

During the storm Sunday morning, one National Weather Service employee measured 3 inches of snowfall in Frederick County, Maryland, as of 8:30 a.m. Nearly an inch had already fallen in northwest Montgomery County by 7 a.m., according to an unofficial observation provided by the National Weather Service.

In Virginia, another National Weather Service employee said 1.5 inches of snow had fallen in Herndon by 8:14 a.m. An observer in Round Hill said 2.6 inches had fallen by 7:35 a.m. Stephens City had 3 inches by 7:55 a.m., according to an unofficial observation provided by the National Weather Service.

The latest snowfall totals complied by the National Weather Service are located on its website.

As a result of Sunday’s weather, Culpeper County Public Schools in Virginia will open two hours late Monday.

Make for extra travel time if you must be travel, and use caution on bridges, highway ramps, overpasses and secondary roads that ice over easily or might not be treated as frequently.

Hot, humid week ahead for DC area with severe storm risk

A dangerous heat wave will grip the D.C. area through Thursday, with highs in the mid to upper 90s and heat index values between 100 and 105. Hot and humid conditions are expected through Thursday, according to the National Weather Service, which said to expect daily thunderstorm chances and a risk of severe thunderstorms. 7News Meteorologist Eileen Whelan told WTOP that most of Tuesday will stay dry, but a few late-day thunderstorms are possible, especially north and east of D.C. as storms drift south from Pennsylvania. Any storm could produce damaging wind gusts and hail, but Whelan reiterated "storm chances are low" on Tuesday. Due to a lack of air conditioning, Parkdale High School in Riverdale, Maryland, closed early at 10:30 a.m. on Tuesday, Prince George's County Public Schools said in a social media post.
