Calm Before The Storm

Normally that phrase is used with Tropical weather, but in our case we are talking about snow. This evening will be fairly nice with diminishing winds and a few clouds. Saturday starts off with increasing clouds and colder temperatures, a foreshadow of what's to come. A rain/snow mix will kick-off the wintry weather event in the afternoon, then becoming all snow Saturday night. The snow will continue into Sunday morning, and by the afternoon clouds begin to move out of our area. For details about snow accumulations, see our March Ain't Over Snow Totals graphic.

The 2019 Blue Ridge Parkway Calendar Photo Contest is underway. You can submit photos now til March, 26. We wanted to keep the momentum going from this year's calendar. So, we'll start now and have calendars on store shelves sooner than ever before.

Forecast Discussion

French Toast Alert Level (FTAS): Elevated; Moderate, plowable snow predicted. Empty your trunk to make room for milk, eggs and bread. Clear space in refrigerator and head to store for an extra gallon of milk, a spare dozen eggs and a new loaf of bread.

High pressure is in place across the region this evening as our next storm system continues to develop over the Central Plains. The high breaks down as the low pressure approaches through the Midwest Saturday. After Sunday, the low devolves and pressure starts to rise in our area to set the stage for increasing temperatures and sunnier skies for the early part of next week. On the horizon, we see a possibility for rain Thursday.

The wintry weather event will start about mid-afternoon Saturday with a rain/snow mix. Heading into Saturday night, the temperature will drop as will the snow. This event will be over by mid Sunday morning and clouds will begin their exit in the late afternoon hours. We are calling for 4-8 inches in our area. However, take that with a grain of salt, as it is likely to change. As I said before, the only thing the models agree on is that precipitation will fall in the form of snow. Please stay tuned; there's much uncertainty here.
