🌱 US Weather Warriors GrowCast — 2026-05-19
Hot, humid, and unsettled across Delmarva today with a Heat Advisory and scattered storms in play.
Today's Weather Snapshot: Highs from the mid-70s along the coast to the mid-90s inland, lows near 64°F. Heat Advisory and multiple Air Quality Alerts active; thunderstorms possible. PoPs run 60-75% from Wilmington through Easton, under 10% at the beaches. Winds near 10-17 mph; dewpoints high enough to make the heat feel worse.
Soil & Recent Rainfall: 2-inch soil temps across DEOS stations average 69.8°F (67-74°F). No measurable rain in the last 24 hours at reporting stations.
Best Outdoor Work Window: Get heavy tasks done before 10 AM — heat, humidity, and storm chances all climb through the afternoon. Inland zones (Wilmington, Dover, Easton) should skip late-day fieldwork; coastal sites stay drier but still hot.
Planting & Transplanting: Soils are well past the 60-65°F threshold for warm-season crops, but the rule today is Delay — hold tender transplants (tomato, pepper, squash, basil) until heat and storm risk ease. Setting them out into 95°F air with storm-driven wind is a setup for transplant shock.
Watering & Irrigation: Hold off — storms are likely across much of the peninsula and the CPC 6-10 day leans wet. Re-check soil by Thursday; coastal sites that miss the storms may need a deep morning watering then.
For Gardeners: Mulch tomatoes, peppers, and cucurbits today to buffer soil temps and conserve moisture ahead of the hot stretch. Harvest lettuce, spinach, and cilantro early — heat will push them to bolt fast. Move container plants out of full afternoon sun if you can.
For Farmers & Growers: Field workability is Poor with storm timing uncertain and wet ground likely by evening — don't start anything you can't finish before a cell moves through. Spray windows are narrow; winds near 13-17 mph and storm outflow make this a poor day for herbicide or fungicide applications. Hay down now is a gamble — wait for a cleaner drying window.
Looking Ahead (6-10 day signal): CPC 6-10 and 8-14 day both favor near-normal temps with above-normal precipitation; no drought across DE, MD, or VA.
Bottom Line: Work early, skip the planting and spraying, and let the storms pass before committing to fieldwork.
