Dry Storm Potential Late Week

The ongoing heatwave is finally starting to wind down, but hot and dry fuels have left fuels more receptive to fire. While uncertainty remains high, there is a chance (10-20%) of isolated, mostly dry, thunderstorms over high terrain on Thursday and Friday this week. Any storms will pose a risk to outdoor recreation and may start new fires.
