A week of frigid temperatures is in store for the D.C. area after three rounds of winter weather, with wind chills below 20 degrees in Monday’s forecast.
A cold front that brought a soaking rain to portions of Northern Virginia and Maryland sent overnight lows plummeting, causing meltwater to refreeze. Monday morning commuters luckily won’t have to worry about snow or freezing rain, but black ice will remain a major concern on untreated surfaces.
“Temperatures will fall below freezing across the entire region by dawn Monday morning. This will result in patchy ice from the lingering moisture from Sunday`s rain and melting snow,” the National Weather Service said. “Early morning motorists should use caution and consider that any surface appearing to be wet may in fact be icy.”

While this week’s outlook has most of the D.C. region steering clear of new snowfall, the main story will be bitterly-cold gusts.
Strong northwesterly winds in the wake of Sunday’s cold front will cause wind chill values to dive into the teens on Monday and Tuesday, with single digits for the higher elevations of West Virginia and far Western Maryland. High temperatures on both days — not factoring in the wind — are unlikely to make it far above freezing.
“That steady wind will stay up overnight Monday as temperatures fall into the 10s and low 20s,” Storm Team4 meteorologist Chuck Bell said. “Tuesday will be the coldest day of the week with most areas staying below freezing the entire afternoon.”
