Another surge of Arctic air has arrived in the Tri-Cities! Frigid temperatures are expected overnight. If clouds clear, we could drop into the single digits to low teens. If it remains mostly cloudy, we'll likely drop into the teens to around 20.
The record low for Saturday morning is 12° set in 1947.
Over the weekend, temperatures will slowly start to creep up. Saturday's highs will still be below average, but it will be dry. Starting Sunday moisture moving in from the Gulf will surge northward into the southern Appalachians. It will be warm enough for rain Sunday afternoon through Wednesday.
If the moisture arrives late Saturday night/early Sunday, a light wintry mix would be possible. The better chance of this occurring will be over southwest Virginia(40%).
Only a few scattered showers are expected Sunday, so a washout isn't expected. The heaviest rain will likely occur Tuesday night into Wednesday.
We will need to be alert for the dangers of rising water on streams/rivers next week. The combination of warmer temperatures, melting snow, and locally heavy rain will result in potential flood concerns.
As colder rushes into the Tri-Cities behind a departing cold front, a few snow showers will will be possible Wednesday night or Thursday. Colder than normal temperatures will once again return for Thursday and Friday of next week.
High temperatures are likely to be in the middle 30s to lower 40s on Saturday. Highs Sunday in the lower 50s...mainly in the 50s to near 60 Monday through Wednesday. Lows in the single digits & teens tonight, 20s Saturday night, near 40 Sunday and Monday nights, and 40s Tuesday night.
Our average high is 54°, low 31°.
