We are tracking a powerful late winter storm in the StormTrack 5 Weather Center. Just when it appeared spring was here, a blast of winter chill is moving back into the Tri-Cities!
StormTrack 5 meteorologists are tracking an area of low pressure that will be in Missouri tonight, northern Kentucky Wednesday morning, and near New York City by Wednesday evening.
Ahead of this front, a mild night is expected with increasing clouds and a chance of showers late. Lows will be in the upper 40s to lower 50s.
As the storm strengthens on Wednesday, a strong cold front will sweep across the southern Appalachians. Windy conditions will develop along with a good chance of showers and possibly a thunderstorm. Highs on Wednesday will likely occur by early afternoon in the upper 50s to lower 60s. Colder air will arrive by later in the afternoon, and temperatures will fall by evening into the 40s across the Tri-Cities and 30s over the higher elevations.
Snow showers are likely Wednesday night, especially over the higher terrain. Though a few snow showers and flurries are possible in the Tri-Cities as well. Gusty winds will continues with lows dropping into the teens to lower 20s. The wind chill factor will drop into the single digits either side of zero over the mountains, and into single digits and teens over the Tri-Cities.
Snowfall accumulations will be on the light side for most. A dusting to a couple of inches is possible for some of the higher elevations. Perhaps up to 3" or so for the favored western-facing slopes. An inch or less is expected for the Tri-Cities.
After a few morning flurries on Thursday, sunshine and brisk conditions are expected. Highs will reach the upper 30s to around 40 across the Tri-Cities, while temperatures across the mountains will struggle to get above freezing.
Friday will start out frigid with lows in the upper teens to lower 20s. By afternoon, temperatures climb into the 50s most areas. Partly cloudy conditions are expected, along with less wind.
Most of race weekend is looking dry. We are tracking a weather system that may bring some showers to the region starting Friday night through Saturday. Right now, Sunday has only a slight chance of showers in the forecast. We will be tracking race week weather and have a better feel for the green flag conditions later this week.
We will be near 60 Wednesday and near 40 Thursday for a high, and upper 40s to upper 50s Friday through next Tuesday. Lows will be in the upper 40s tonight, upper teens to lower 20s Wednesday and Thursday nights, and 30s Friday and Saturday nights.
Our normal high 58°, normal low 33°.
