Unsettled conditions this Sunday over southern Oregon may disrupt Memorial Day weekend festivities, with the National Weather Service in Medford warning of isolated thunderstorms between 3 p.m. and 9 p.m. today, Sunday, May 25.
Storm development expected this afternoon
A 10–25% chance of thunderstorm activity is forecast across the southern portion of the state, with the highest risk centered around the late afternoon into early evening. While these storms will remain isolated, frequent lightning and damaging wind gusts between 45–55 mph (72–89 km/h) are the primary threats.
Rainfall is expected to be light, and hail is not forecast to exceed 1 inch (2.5 cm) in diameter. However, the marginal risk classification from the Storm Prediction Center underscores the potential for spotty but impactful weather, especially where people are gathered outdoors.
Key areas of concern
Communities at risk include:
- Medford
- Klamath Falls
- Grants Pass
- Ashland
These cities may experience brief but intense bursts of wind and lightning, particularly during late afternoon hours.
Safety concerns amid holiday events
With outdoor gatherings, barbecues, and regional travel peaking during the Memorial Day weekend, forecasters are emphasizing lightning safety and readiness. Officials urge residents and travelers to:
- Keep mobile weather alerts enabled
- Move indoors at the first sound of thunder
- Stay away from tall objects and open fields
Although storm activity is expected to weaken after 9 p.m., new updates could be issued depending on how conditions evolve through the evening.
