  • Very isolated convection remains possible today, followed by generally dry conditions for the rest of the week.
  • We will see a very brief reprieve from the heat later this week, most notably felt on Thursday and Friday morning.
  • While it is still very early, a more active pattern looks possible heading into next week.
