First Rain Potential in Weeks Today – Daily Forecast for Monday, September 23rd, 2019

Much of the state hasn’t seen measurable rain in multiple weeks, and today looks to bring the first chance in weeks. Unfortunately, it won’t be much and may be the last chance for a while. Highs will be summer-like for the first day of fall in eastern PA, nearing 90 in the valleys. Have a good Monday (or at least attempt)!
