Safety Tips During Extreme Heat
Chances of thunderstorms (30-60%) are forecast to increase late tonight and 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. However, if any storms were to become severe, locally damaging winds and large hail will be the primary hazards. Make sure to monitor the forecast for the latest details!
