A stray shower will be possible early, then dry through the rest of the night. Temperatures will slowly decrease through the evening and overnight. Lows will only cool to the low-to-mid-70s. Heat is the main story through the holiday weekend. Thursday through Sunday will be Weather Impact Days due to the extreme heat. Anyone who spends extended periods of time outside should take frequent breaks and hydrate often Highs in the mid to upper 90s, with some lower 90s in the mountains, are expected.
