Delmarva’s weather pattern through the weekend and into next week will be dominated by a series of frontal boundaries bringing waves of warmth, humidity, and scattered thunderstorm chances. Friday begins cooler with cloud cover and a few showers, but a shift to a more southerly flow will increase temperatures through the weekend. The region could see highs in the 90s by early next week before another cold front arrives with a possible round of thunderstorms. Despite the unsettled pattern, extreme heat and widespread severe weather are not expected.
