of 100-degree heat and worsening drought, the region got a very helpful respite
this past week as a large-scale pattern change brought increased clouds, rain
chances, and cooler temperatures. While heavier rainfall was generally
localized, and we’re still far off from breaking our severe to extreme drought

the area from the north. The front will likely stall before it crosses the area,

hot and humid conditions will likely persist these days as well. By Sunday, the
front looks to wash out, and that will allow the hotter/drier pattern to become
reinforced once again as we head into next week. After slowing in recent days, drought impacts will likely begin to accelerate again under this
regime.
