Key Messages

  • Warm and predominantly dry conditions continue through most of the work week. Low (15-25%) chance for showers Thursday night into early Friday morning, mainly south of US Highway 18.
  • Warm and dry conditions and occasionally gusty afternoon winds could bring some fire weather concerns as grasses dry out, with Saturday being the focus for stronger wind gusts.
  • Better rain chances (20-40%) and cooler temperatures look to return early next week, but confidence in details remains low.
