You might just want to shut the windows tonight (unless you are like me and sleep with a couple layers of blankets 🙂 ) as temperatures will dive down into the middle to even lower 40s overnight. Several factors will come together to allow this as our skies remain clear and winds light. Tomorrow begins one of many days in which a gradual warming trend will take place that will ultimately get our daytime highs back to where they should be for this time of year. Make sure and plan some outdoor time for tomorrow as it will be perfect for just about everything (except swimming perhaps). Have a great Sunday!
