Plunging temperatures, snow, and flash freeze possible Tuesday evening in Washington region

The weather agency says it's likely to be a light dusting with snowfall accumulations of less than an inch across our area - but adds, "Stay tuned to updates regarding accumulations to this possible event".

Very cold conditions are expected on Tuesday with highs between 10 and 12.

"Whether we see a flash freeze and icy roads will depend on how quickly the arctic air moves in before the dry air shuts off our precipitation", said Wes Junker, Capital Weather Gang's winter weather expert.

Since the event will start as rain Monday night it'll be hard for TDOT workers to treat the roads, and with snow falling during the morning commute roads will likely be quite slick.

"So we will see more persistent rain for northern and western areas gradually working its way east".

Variable clouds Friday with a high in the low teens.

Remember how cold it was when we rung in 2018?
