We are tracking a departing area of high pressure that will bring winds from the south and southwest today. Mild conditions and areas of fog this morning. Warm and breezy this afternoon.
As a slow moving cold front moves towards the area, the air flow will run parallel to it today. Rain could become heavy at times, especially near the KY/VA line. I wouldn't be surprised if we see a few renegade thundershowers today. Breezy conditions will ensue as well.
With heavy rain in the forecast, we will need to be alert for the dangers of rising water on streams/rivers this week. Snow pack is melting and the ground is saturated. This is something worth keeping an eye on as rainfall totals by mid-week could exceed one inch. A Flood Watch is in effect for southeast Kentucky and most of southwest Virginia through Thursday.
Behind this passing cold front, we are keeping our eyes on a storm system that will begin intensifying on the leeward side of the Rocky Mountains. A very pronounced jet stream, cold air and this storm system will bring wintry weather back into the region.
Late tonight and early Thursday, colder air rushes into the Tri-Cities. Temperatures will drop very quickly! Some models are bringing in warmer air aloft in the Tri-Cities and areas eastward. Rain will change over to freezing rain and sleet from northwest to southeast early Thursday morning, likely before morning commute time. This 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. Some accumulation appears likely at this point, especially near the KY/VA line. Lift along the higher terrain will result in more accumulations. Accumulations of up to 3" 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 possible winter storm.
A Winter Storm Watch is in effect for the Tri-Cities area. A Winter Storm Warning is in place near the KY/VA line for tonight and Thursday.
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.
Highs in the 60s today...30s Thursday and 40s Friday and near 50 this weekend. Low to mid 50s through early next week. Lows in the 30s tonight, 10s Thursday and Friday night, and near 30 Saturday and Sunday nights.
We "Spring Forward" one hour Saturday night!
Our average high is 55°, low 31°.
