Weather Summary:

We are tracking pleasant conditions in the StormTrack 5 Weather Center. The northwesterly flow with the cooler and less humid conditions with continue in the Tri Cities this afternoon. We have set a new record low this morning. We have been as low as 52°.

The low for today was 56° and Thursday is 55°. We will be tracking the potential for a record low before the southern Appalachians start to warm-up and humidity return.

The mostly clear skies tonight will create comfortable conditions but we may be near another record low.

Thursday will start out mostly sunny but we will see an increase in clouds Thursday afternoon. There is a slight chance, 20 percent or less, for a late day shower. Any danger of thunderstorm threats will be isolated at best.

StormTrack 5 Meteorologists are tracking the jet stream continuing to bend south over our area. A disturbance will travel through that jet and increase our shower chances to 40 percent on Thursday night.

The shower and thunderstorm chances will be at least 50-50 for Friday and Saturday. A disturbance will keep possibly showers and thunderstorms for Monday with a 30 percent chance.

The upper level steering currents has been holding the jet stream south but it appears that pattern will change somewhat to start the new week. The upper level pattern change will also bring and end to the shower chances as drier weather will become the feature.

A 20 percent or less chance is the way we start the week. Monday will be mainly a late afternoon chance while just a marginal chance exists on Tuesday.

Highs will be in the upper 70s to low 80s this afternoon through Monday and mid 80s on Tuesday. Lows will be in the low 50s tonight. Expect upper 50s to low 60s Thursday night through Tuesday night.
