Weather Summary:

We are tracking a cold front in the StormTrack 5 Weather Center. This front will pass through the Tri-Cities this evening. As the front makes it's way into the southern Appalachians we will see another day of showers and thunderstorms. The front is interacting with the warm and humid air still in place across the area. The showers will continue into tonight and ending early Friday.

As the front slides east of the southern Appalachians and we get a more west to northwest flow, a cooler and drier airmass will settle in. We will return to sunny skies Friday afternoon and with clear skies Friday night we may see some chilly lows. Saturday morning some mountain valleys may have some scattered frost.

StormTrack 5 Meteorologists are tracking a pretty good weekend although we will be slightly below normal on the temperatures. A high pressure will keep us sunny and dry for the weekend. Your holiday weekend plans should be good weatherwise, for the outdoors.

We are tracking a mainly pleasant day in Memorial Day. A warm front to our north on Monday may bring a slight shower chance. As the moisture and temperatures start to rise again on Tuesday and Wednesday, so do the shower and thunderstorm chances. It appears that we will have a 20 percent chance of those afternoon and evening pop-up showers and thunderstorms Monday through Wednesday.

Highs will be in the upper 70s this afternoon and mid 60s on Friday. We expect low to mid 70s Saturday and Sunday with upper 70s and low to mid 80s Monday through Wednesday. Lows should be in the low 50s tonight. We may cool to the upper 30s Friday night but back to low to mid 40s Saturday and Sunday night. We should be back into the low to mid 50s Monday night through Wednesday night.

Our normal high is 78, low 53.
