🌱 US Weather Warriors GrowCast — Thursday, August 20, 2026
Flood-watch thunderstorms and wet ground sharply limit field access and outdoor work across Delmarva today.
Today's Weather Snapshot: Delmarva temperatures range from 66°F to 87°F. Thunderstorm chances run from 62% to 87%, with a Flood Watch active. Winds range from near 5 mph to about 18 mph. Overnight relative humidity ranged from 89.5% to nearly 100%.
Soil & Recent Rainfall: Two-inch soil temperatures range from 72.3°F to 78.7°F. DEOS stations recorded 0.0 inches of rain in the past 24 hours. Wet ground and poor soil workability remain the operational concern.
Best Outdoor Work Window: Skip today — thunderstorms, flood concerns, wind, and wet ground leave no reliable work window.
Planting & Transplanting: Delay planting and tender transplants until the weather trend improves. Soils are well above the 60–65°F threshold for warm-season transplants, but field conditions are poor.
Watering & Irrigation: Hold off on watering until the rain trend passes; soils may already be wet. No irrigation is needed today with widespread thunderstorm chances and flooding concern.
For Gardeners: Harvest ripe tomatoes, peppers, squash, and cucumbers before storms arrive. Keep cool-season vegetables shaded where practical, as heat can reduce quality or trigger bolting. Avoid mowing lawns or working garden beds where the ground is wet.
For Farmers & Growers: Keep equipment out of wet fields and protect soil structure from rutting and compaction. Avoid spray applications with thunderstorms possible and winds reaching about 18 mph. Hold hay cutting and other weather-sensitive harvest work until a drier window develops.
Looking Ahead (6-10 day signal): The 6–10 day outlook favors above-normal temperatures and precipitation, while Delaware, Maryland, and Virginia remain free of drought.
Bottom Line: Treat Thursday, August 20, 2026 as a weather-delay day for planting, fieldwork, spraying, and irrigation.
