[4:07 AM] We're continuing to assess the damage from the June 17-18 storms, but we're also looking ahead to Sunday through Monday, when a chance of heavy rain will move into the area. Some flooding will be possible.

06/18/2026

Expect continued windy conditions, heavy rainfall, & rumbles of thunder in the next hour. We are not observing imminent weather to happen at this time. But remember, weather has a mind of it's own and can change very quickly! (yesterday for example, the funnel cloud). Please have your multiple warnings if you decide to call it a night and we will continue to keep you updated.

While conditions are still unknown as it approaches our county. We STILL will get damaging winds. Our ground is saturated, with winds 75+ large trees could be pushed over. Please remain weather aware. Will update as we can.

To answer your questions about future watches - this will come down to how storms perform over the next few hours. And how our environment comes together.

The ground is already saturated from recent rain, which means trees can be knocked over more easily when strong winds arrive.

⏰ Main threat window: 8 PM – 2 AM

Primary threats include:
🌬️ Damaging winds
🧊 Large hail
🌪️ Possible tornadoes

While flash flooding is possible, the greater flood threat is expected to stay to the tristate area.

Remember: Damaging straight-line winds can cause damage similar to a tornado, especially when the ground is wet and trees can uproot more easily.

If you think you may need to shelter elsewhere, please call friends, family, churches, or public buildings ahead of time rather than showing up unannounced.

Stay prepared, not scared, and have multiple ways to receive weather warnings tonight.

Funnel clouds are not tornadoes. A tornado is when the funnel touches the ground. When you do see a funnel cloud get to your safe spot right away! Funnels can spin up quick to a tornado. We stress our area isn't the greatest in radar coverage, if you see something say something so we can get the warning out for our community. Thank you all for your quick actions to spotting the funnel!

**Expired** Tornado warning until 845pm June 16, 2026. A funnel cloud has been seen with this storm.
