Delaware – Sunshine is quickly warming pavement across northern Delaware this late morning, and an even hotter stretch is waiting just ahead. The comfortable start to the day will give way to building summer heat, with Wilmington expected to experience its hottest weather of the week by Wednesday.
According to the National Weather Service in Philadelphia/Mount Holly, dry weather remains firmly in place across the region as high pressure dominates the Mid-Atlantic. Temperatures climb to 84 degrees today before rising sharply to 90 degrees Tuesday and peaking near 97 degrees Wednesday under abundant sunshine. Thursday remains very warm with highs around 93 degrees.
The steady warming trend will make each afternoon feel noticeably hotter than the last. Asphalt parking lots, sidewalks and vehicles parked in direct sunlight will heat rapidly by midday. Plan outdoor work, exercise and yard projects during the cooler morning hours whenever possible. Stay hydrated and take frequent breaks in air-conditioned spaces.
Motorists traveling along Interstate 95, Interstate 295, Route 202 and Route 141 should prepare for increased vehicle temperatures during afternoon commutes. Keep bottled water in your vehicle and never leave children or pets unattended inside parked cars, even for a few minutes.
While severe thunderstorms and flash flooding continue across portions of the Plains and Midwest, the weather pattern over Delaware remains quiet through midweek. Only a 30 percent chance of showers returns Saturday, bringing the first opportunity for meaningful rainfall after several days of sunshine.
Looking beyond midweek, temperatures ease only slightly while remaining above seasonal averages. Climate Prediction Center outlooks continue favoring above-normal temperatures across the Mid-Atlantic during the 6-to-10-day period, suggesting the summer heat will likely persist into next week.
