🌱 US Weather Warriors GrowCast — Thursday, July 16, 2026
Dangerous heat headlines the day across Delmarva, with scattered afternoon storms possible and air quality alerts up.
Today's Weather Snapshot: Highs 85-96°F, lows in the mid 70s — no overnight relief. Heat Advisory and widespread Air Quality Alerts in effect. Winds near 9-15 mph, with elevated thunderstorm chances inland (PoP up to 41% at Dover). Dewpoints and humidity are oppressive; RH running 92-99% at mesonet sites this morning.
Soil & Recent Rainfall: 2-inch soil temps averaging 79.4°F across six DEOS stations (75.0-81.8°F). No measurable rainfall in the last 24 hours at reporting sites.
Best Outdoor Work Window: Before 10 AM today, full stop. After that, heat index and storm potential shut the window down — resume early Friday morning.
Planting & Transplanting: Planting window is Delay. Soils are plenty warm for warm-season crops, but transplanting into this heat will cook tender starts — hold tomatoes, peppers, and cucurbit transplants until the pattern breaks.
Watering & Irrigation: Despite dry gauges, hold irrigation ahead of possible heavy/excessive rainfall signaled by WPC and scattered storms this afternoon. If storms miss your block, water deeply at dawn Friday rather than midday today.
For Gardeners: Prioritize deep morning watering on containers, tomatoes, and cucurbits, and shade cloth over lettuce, spinach, and any cool-season holdovers to slow bolting. Skip fertilizing, pruning, or transplanting today. Harvest ripe fruit early to prevent sun-scald and splitting if storms hit.
For Farmers & Growers: Field workability is Poor between heat, wind gusts, and storm timing — spray windows are unreliable and drift risk climbs with afternoon outflow. Push hay cutting until a drier, cooler stretch verifies. Check livestock water and shade first; scout for spider mites and stress in beans and cucurbits.
Looking Ahead (6-10 day signal): CPC 6-10 day leans above normal temps and above normal precip; drought-free across DE/MD/VA.
Bottom Line: Work at dawn, hydrate, and let the heat and storms have the afternoon.
