Weather Summary:

A slow moving cold front has moved through the area.  Behind this front, the air flow will run parallel to an upper level storm system producing a long line of showers.  Rain could be heavy at times early.

With heavy rain in the forecast, we will still need to be alert for the dangers of rising water on streams/rivers. Snow pack is melting and the ground is saturated. A Flood Watch is in effect for southeast Kentucky and most of southwest Virginia today.  Flood Warnings are in effect for parts of southwest Virginia.

Behind this passing cold front, we are keeping our eyes on a storm system that has intensified over the Rockies.  A very pronounced jet stream, cold air and this storm system will bring wintry weather back into the region.

Colder air is rushing into the Tri-Cities.  Temperatures will drop very quickly!  Some models are bringing in warmer air aloft, so rain will change over to freezing rain and sleet from northwest to southeast early today, likely around commute time.  This icy mix will then change to snow along the KY/VA line first before changing to snow and sleet in the Tri-Cities and areas pointing eastward this morning.  Some accumulation appears likely at this point, especially near the KY/VA line.  Lift along the higher terrain will result in more accumulations.  Factors that will limit accumulation include the wet soil (especially SW VA) and the mild recent weather (especially NE TN).  With such a strong storm system however, we still think that accumulations of around 2" or less are possible in the Tri-Cities and around 2" to 5" near the KY/VA line (more possible in higher elevations that change to snow more quickly). Check back for updates on this winter storm.

A Winter Weather Advisory is in effect for all of northeast Tennessee, along with the NC High Country up through Smyth County. A Winter Storm Warning is in place until this afternoon near the KY/VA line, including Russell, Washington and Scott counties in SW VA.

High pressure fills back in Friday through early next week. As a result, the air will descend and the weather will be less active.  We'll see lots of sunshine as we wrap up the first week of March and head into the second week!  Temperatures will slowly make their way up again during this time.  A chance of rain returns Tuesday and Wednesday of next week, as a low pressure system rides up from the Gulf. 

Highs in the 30s today (falling temperatures)...40s Friday and near 50 this weekend.  Low to mid 50s through early next week.  Lows in the 10s tonight and Friday night, and near 30 Saturday and Sunday nights.

We "Spring Forward" one hour Saturday night!

Our average high is 56°, low 32°.
