Spring Has Sprung?
Astronomical Spring began today at 12:15pm (insert funny joke about it not feeling like Spring here). Since it was in the 70's a few times last month it's fitting that on the night Spring begins it snows. Rain showers return in abundance as we progress from the mid-afternoon to evening hours. Once again, a rumble of thunder is not out of the question.
Rain transitions to snow from the top down around midnight. If you are awake then, pay attention to the wind direction. Once we tap into a northwest wind the transition to snow is within a couple of hours. Snow showers continue Wednesday and taper off late Wednesday night into early Thursday morning. As expected for a prolonged northwest flow snow event, the mountaintops and westward facing ridges closer to the TN/NC border get the most. For details about snow accumulations, see our Welcome to Spring Snow Totals graphic. Of course it all comes with wind :-), gusts to 50 mph will be common later tomorrow through Thursday.
The 2019 Blue Ridge Parkway Calendar Photo Contest is underway. You can submit photos 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.

Another dynamic early Spring storms is in the works today. Dueling low pressure centers, one in the TN Valley and another near the Carolinas Coast work in tandem up the eastern Seaboard and phase together late Wednesday. Rain showers, perhaps a rumble of thunder is the story from later this afternoon into the early nighttime hours.
Colder air arrives quickly tonight as the low pressure centers begin moving north. Rain changes to light snow and snow showers around midnight. A strong and rather moist northwest flow keeps the snow theme going into early Thursday morning. The bigger winners are the higher ridges and westward facing slopes along the TN/NC border. However, we all receive shovelable and plowable snow from this one over the course of about 30 hours. However, the higher March sun angle will eat into what's on the ground tomorrow afternoon.
Thursday and Friday are dry, but also remain on the chilly side (especially Thursday with the wind). The next wet weather maker gets here Saturday afternoon with spotty light rain sticking around through Sunday. There's several questions marks with regards to the weekend so we'll not etch that in stone. It's not out of the question some snow mixes at some point in there as well.
