Safety Tips During Extreme Heat
Scattered thunderstorms (30-60%) are forecast to develop Wednesday night into Thursday across our north, some of which could become strong to severe. Uncertainty remains on the exact storm coverage and timing, and these outlook areas could shift northward or southward over the next day. However, if any storms were to become severe, large hail and localized damaging winds will be the primary hazards. Make sure to monitor the forecast for the latest details!
