A potent area of low pressure will move from the southwest and track toward DC Sunday morning. With abundant cold air in place, snow will start during the early morning hours from west to east. The first flakes inside the Beltway are likely around 9 a.m.
Temperatures will play a critical role in the forecast. With little mixing expected at first, snow may accumulate one to three-inches before changing to sleet and freezing rain. The chances for ice accumulation will increase west of Interstate 95 with the heaviest ice totals in this area. Upwards of one-quarter inch of ice is likely to accumulate on trees, power lines, bridges and cars. Untreated roadways will become difficult to navigate.
Freezing rain changing to all rain will continue late Sunday night. Another period of rain will arrive for the Monday morning commute.
