🌱 US Weather Warriors GrowCast — Tuesday, June 9, 2026
Heavy rainfall and thunderstorms move into a warm, humid airmass — field and garden work takes a back seat today.
Today's Weather Snapshot: Highs from the upper 70s along the coast to near 89°F inland; lows in the low 60s. WPC guidance points to heavy or excessive rainfall, with thunderstorms in the mix. Winds around 10-17 mph, breeziest near the beaches. Humidity running high behind overnight saturation at most mesonet sites.
Soil & Recent Rainfall: DEOS 2-inch soil temps average 67.2°F across six stations, ranging 60.5-70.8°F. No measurable rain in the past 24 hours; topsoil reporting dry at DTBR, DDFS, DGES, DLAU, and DAGF heading into today's rainfall.
Best Outdoor Work Window: Early morning before storms develop is your only realistic window. Skip the bulk of the day — reassess Wednesday once the front clears.
Planting & Transplanting: Soil temps are sitting comfortably above the 60-65°F threshold for tomato, pepper, and squash transplants, but the planting window is Delay today. Hold tender transplants until heavy rain and storm risk pass — saturated ground and pounding rain will undo a careful set.
Watering & Irrigation: Hold off on irrigation. With excessive rainfall guidance in play and PoPs up to 67% at Wilmington, soils will be wet by evening regardless of what they look like now.
For Gardeners: Get tomato cages, stakes, and trellises secured before the storms arrive — wind gusts with thunder will test anything loose. If you've got cool-season greens still in the ground, harvest what's mature this morning; heat and heavy rain will hammer lettuce and spinach quality. Hold off on bedding plant installs until the pattern dries out.
For Farmers & Growers: Field workability is Poor and worsening; postpone tillage, planting, and sidedress passes. Spray windows are closed — wind is borderline and storm timing makes coverage and drift a problem. If hay is down, this is a loss-mitigation day, not a baling day.
Looking Ahead (6-10 day signal): CPC 6-10 day leans above normal temperatures; 8-14 day signals below normal precipitation, with no drought currently across DE, MD, or VA.
Bottom Line: Stand down on fieldwork and planting today — let the storms pass and reassess midweek.
