A Winter Weather Advisory is in effect for D.C. and parts of Maryland and Virginia from 7 p.m. Sunday to 10 a.m. Monday, with areas to the north and west of the capital most at risk for snarled rush hour traffic from icy conditions.
WASHINGTON — Another round of winter weather is in store for the D.C. region, with snow, sleet and freezing rain all factoring in to a bleak outlook for the Monday morning commute.
Expect slow travel from a period of light snow, sleet and freezing rain moving in from west to east starting Sunday evening and lasting through Monday morning.
A winter weather advisory is in effect for D.C. and parts of Maryland and Virginia from 7 p.m. Sunday to 10 a.m. Monday, with areas to the north and west of the capital most at risk for snarled rush hour traffic from icy conditions.
Freezing rain and sleet will be the biggest concerns of Monday’s storm, which is expected to kick off Sunday night with a wintry mix.
The National Weather Service said Northern Maryland can expect less than one tenth of an inch of ice by sunrise, enough to make things potentially difficult for travelers. Authorities in Virginia weren’t taking any chances and were already treating roadways well in advance of Sunday night’s system.
“Icing will be an issue for some Monday morning,” NBC Washington meteorologist Somara Theodore said. “The degree to which this wintry weather will impact us still varies, but I would expect some delays.”
There’s still some uncertainty in the forecast, but snow totals weren’t looking all that impressive.
The best odds for up to two inches of snow are limited to Northern Maryland along the border with Pennsylvania. D.C. itself can expect up to an inch of snow, with an outside chance for over an inch — though a relatively warm, stable air mass and an anticipated changeover to all rain by midmorning Monday should act to keep snow accumulation low.
“Given dry air in place, feel it likely most places see some snow and sleet at the onset, with snow likely to linger much if not most of the night and morning on Monday in northern Maryland,” the National Weather Service said in its Sunday morning forecast discussion. “Thus, have highest accumulations generally along the Interstate 70 corridor, with lower amounts elsewhere.”
Watches and warnings:
A Winter Weather Advisory is in effect for the following parts of the WTOP listening area:
In Maryland: Prince George’s, Anne Arundel, Howard, Montgomery, Frederick, and Carroll counties, from 7 p.m. Sunday to 10 a.m. Monday.
In Virginia: Arlington, Fairfax, Loudoun, Prince William, Fauquier, and Clarke counties, including the cities of Alexandria, Fairfax, Falls Church, Manassas and Manassas Park, from 7 p.m. Sunday to 10 a.m. Monday.
A Winter Weather Advisory means periods of snow or other winter weather will cause travel difficulties. Expect snow covered roads and limited visibilities, and use caution while driving.
A second storm is in store for Tuesday. Like the first, it’ll start out with a wintry mix on Monday night, and transition to rain through Tuesday morning. Though timing and exact impacts are somewhat unclear, Northern Maryland along the I-70 corridor was again looking to face the most significant impact from round two.
In its Sunday forecast discussion, NWS said those areas will likely again need winter weather advisories or warnings following Monday’s winter blast.
Sunday: Sunny to start, then light snow or a wintry mix in the afternoon to evening. Highs in the low 40s.
Monday: Light snow or a wintry mix in the morning, changing to all rain. Highs near 40.
Tuesday: Another chance for an early wintry mix, then rain. Mostly cloudy. Highs in the low 40s.
Wednesday: A damp start, then mostly sunny and breezy. Warmer, with highs near 50.
