For the ninth time this June, high temperatures exceeded 90° in the Tri-Cities earlier Sunday. The warm air and humidity aren't going anywhere any time soon, though, as they'll both be in good supply on Monday. Combine that warm air and humidity with a weak cold front, and you've got a chance for storms.
It won't be raining the entire day on Monday. While we can't rule out a few isolated storms in the morning, the better likelihood of seeing one is after lunchtime. Rain will be heavy in spots. The slow movement of any storms could lead to some isolated flooding issues. Granted, not everyone will see this - but it's something worth keeping an eye on.
A few leftover showers are possible early Tuesday, as this front slowly moves south and east of the area. Behind the front, drier air settles in - leaving us sitting comfortably warm through Wednesday and Thursday. Most of Friday stays dry, though we'll have to keep an eye on a weather system coming in from the Plains.
While it may give us a few thunderstorms Saturday, the better chance for rain appears to be next Sunday. It all depends on where that storm system tracks along a stalled front. The location of that is the difference between some high rain totals and scattered showers/storms. Stay tuned as we continue to fine-tune that forecast during the week.
Temperature Outlook: Highs in the 80s all this week. Lows in the 60s through Monday night - 50s to low 60s through Thursday night - then back to 60s Friday and Saturday nights.
Our average high is 85°, low 63°.
