NEXT WEEK
As we look into next week, expect two distinct weather patterns. Initially, it will be hot and mostly dry, but we’ll see an increase in rain chances that could provide some relief from the heat as the week progresses. Keep an eye on Wednesday, Thursday, and Friday, as a weak frontal boundary may move close enough to kick off some weather activity.
