DELMARVA - It's a mild start to our Sunday with partly cloudy skies and temperatures in the 60s and 70s. A cold front will sweep through on Sunday, helping to break the heat. Highs will still reach the low 90s, and it will remain muggy. A few isolated gusty thunderstorms are possible, for the southern portion of Delmarva. The main threat with any stronger storms will be damaging winds.
Behind the front, high pressure builds in from the north early next week. That will bring briefly cooler temperatures, with highs in the 70s and 80s to start the week. Mainly dry weather is expected through much of next week, with temperatures gradually warming again as high pressure slides offshore and southerly flow returns.
The main forecast concern for the second half of next week will be another stretch of above normal heat, however, isolated to scattered showers and storms develop Thursday and continue into the weekend, bringing a little relief to the drought conditions.
