Dangerous heat continues, with heat indices between 100 and 110 degrees through at least Wednesday. An Extreme Heat Warning remains in effect area-wide through 10 PM Wednesday. Stay cool and hydrated if you have outdoor plans! Increasing chances of storms late week could bring relief from the heat leading into the 4th of July.

Heat safety tips
Chances of thunderstorms (20-50%) are forecast to increase Wednesday night across our north, some of which could become strong to severe. Uncertainty remains on the exact storm coverage as it's possible this could shift northward, limiting our severe threat. However, if any storms were to become severe, large hail and locally strong winds will be the main hazards. Make sure to monitor the forecast for the latest details!
