Thankfully, a cold front is going to break up this hot and humid pattern. Sunday will start off mostly sunny, but clouds will be increasing well ahead of this front. North of 74 could see some showers and isolated thunderstorms tomorrow late morning as a small wave of energy ushers through ahead of the front. The chance for severe storms is low, but heavy rain is a possible concern wherever these storms develop. The afternoon looks be mostly dry, but an isolated shower or storm can’t be ruled out.

Better shower and storms chances arrive with the slow-moving front overnight Sunday into Monday morning. A few rumbles will be likely to wake you up Monday morning. Again, severe storm probabilities are low, but heavy rain and flash flooding is a concern considering how moist the airmass in place currently is. Make sure you have the 25 News First Alert Weather app downloaded, because it will alert you of any flash flooding in your area if that happens to develop from these storms.
