Flash Flood Potential Increasing for Tomorrow Evening
Aug 20, 2026
If you’re making plans for Friday evening, it’s important to stay Weather Wise! We’re going to see a noticeable uptick in showers and thunderstorms, and some of these storms could produce heavy rain in a short amount of time, which could lead to Flash Flooding.
The biggest concer
n is not necessarily severe weather, it’s how much rain could fall and how quickly it could come down.
The Weather Prediction Center has placed our area under a Level 2 of 4 risk for excessive rainfall tomorrow, which means there is a marginal-to-elevated concern for flash flooding, especially in areas that see repeated rounds of heavy rain.
Tomorrow Evening: This is when I’m watching things closely 5pm-11pm
Some storms could sit over the same locations or move over areas that have already picked up rain. That’s when things can get tricky.
A quick 1-3 inches of rain in a short period of time can overwhelm drainage systems, and low-lying areas. These will be slow-moving storms dumping rain over the same neighborhood for multiple hours.
What we are watching
Friday evening through the overnight hours will be the period we are watching closely.
Widespread delays and possible cancellations are possible.
Most importantly, never drive through a flooded roadway. Turn around, don’t drown. Water can rise quickly, and it can be extremely difficult to tell how deep that water actually is.
The good news? This isn’t a washout for the entire day. We should still have some dry time, especially earlier in the day.
Stay tuned!
