ALERTS: A Winter Weather Advisory continues through Thursday morning for the Alleghany Highlands, Tazewell, Smyth, Grayson, Wythe, Bland and Giles
A Winter Storm Warning is in place through Thursday morning for western Greenbrier county in West Virginia. A strong northwest flow and mountain snow showers will continue to fall through mid week with significant snow expected across the western facing slopes, and ski country.
SNOW POTENTIAL: The upper low will continue producing snow across the Ohio Valley that will slide into the area through early Thursday. For most areas, occasional snow showers will bring a light coating when they move through.
In the mountains (West Virginia/Virginia border counties and the I-77 corridor) snow could top 1" or more during any burst of snow.
Watch for slick spots as temperatures will remain at or slightly above freezing during the day, dropping to the teens at night.
This is going to be the longest cold snap we've had this winter, or even in the past year. Highs have a hard time getting above freezing on Wednesday and Thursday, but the coldest of air arrives over the weekend with air temperatures only in the teens and 20s. Overnight lows will easily slip to the teens and single digits.
WIND CHILLS: Added wind gusts of 15-25mph will force wind chills (feels like temperatures) below zero, especially in the mornings.
WIND CHILL ADVISORIES go into effect midnight Wednesday through 10am Thursday.
FRIDAY SNOW CHANCE?
With the cold air locked in place, we need to be looking for any moisture source that could bring wintry weather.
We're keeping an eye on several opportunities for light snow. The first chance is Friday with a quick-moving system that may bring some light snow showers. Only a few of the models are "seeing" this one, but it's something to monitor.
CONFIDENCE LEVEL: Medium
MONDAY-TUESDAY SNOW CHANCE?
The next system we're watching is showing up on the European and Canadian models for Monday-Tuesday. An active jet stream moves overhead with a developing southern system. It's not strong, but a jet streak can often help to enhance any available moisture, helping squeeze out some snow. Again, this one isn't a done deal either, just something to monitor.
CONFIDENCE LEVEL: Low
