A severe thunderstorm watch is in effect as intense storm systems move into the Twin Cities early Saturday, August 9, 2025. The watch, originally set to expire at 4 a.m., has now been extended until 6 a.m., as the storms push further east into parts of Wisconsin. Residents are urged to remain alert as conditions remain favorable for damaging winds, hail, heavy rainfall, and frequent lightning.
The storms began late Friday night, intensifying as they moved into the metro area. Powerful cells brought hail, intense downpours, and continuous lightning, creating hazardous conditions for anyone outdoors or on the roads. While no active severe thunderstorm warnings are currently in place for the core metro, the extension of the watch signals that threats persist through the early morning hours.

Key Developments During the Severe Thunderstorm Watch
- Extended coverage – The watch now includes a broader area, stretching from the Twin Cities into western Wisconsin.
- Heavy rainfall – In some areas, as much as two inches of rain fell within a half-hour period, leading to localized street flooding.
- Hail reports – Hail up to an inch in diameter has been observed, especially in northern parts of the metro.
- Frequent lightning – Nearly constant flashes illuminated the night sky, posing risks to outdoor activities and power systems.
- Wind gusts – Peak gusts have exceeded 60 mph in certain pockets, bringing down tree branches and damaging property.
Power Outages and Local Impact
Thousands of residents have been affected by temporary power outages due to downed lines and damage from falling limbs. Utility crews are working to restore electricity as quickly as possible, but with the storms still active in some areas, complete restoration may take several hours.
Road conditions are also a concern, with standing water reported on low-lying streets. Motorists are urged to reduce speeds, avoid flooded areas, and use extra caution when visibility is reduced by heavy rain.

Forecast for the Rest of the Weekend
After the severe thunderstorm watch expires, skies are expected to begin clearing later in the morning. Saturday afternoon will bring warm and humid weather, with highs in the mid-80s. Another round of isolated showers is possible late Saturday night, though less intense than the overnight storms. Sunday is expected to be mostly sunny, with a slight drop in humidity.
Preparedness Tips During a Severe Thunderstorm Watch

- Avoid windows to reduce the risk from shattered glass if debris hits.
- Secure outdoor objects like patio furniture and trash bins.
- Charge devices in case of power outages.
- Monitor weather updates for any escalation to warnings.
What’s Next
Meteorologists will continue to monitor the storm system as it moves across the region. While the most intense cells are expected to clear the Twin Cities by early morning, the potential for lingering showers and gusty winds will remain until the cold front passes completely.
The extended severe thunderstorm watch serves as a reminder that summer storms can develop quickly and pack dangerous conditions. Residents are encouraged to review their severe weather plans and stay informed for any additional watches or warnings issued later in the weekend.
