🌱 US Weather Warriors GrowCast — Thursday, June 18, 2026
Heat, gusty winds, and a high thunderstorm risk push storm safety and field timing to the top today.
Today's Weather Snapshot: Highs 83-94°F across Delmarva, lows near 69-74°F. Scattered storms likely, with PoPs climbing 60-80% across the lower Eastern Shore and Virginia coast. Winds steady near 20-21 mph under an active Wind Advisory. Humidity is high — dewpoints elevated and a Heat Advisory is in effect.
Soil & Recent Rainfall: Two-inch soil temps averaged 74.7°F (range 72.7-77.8°F) across six DEOS stations. No measurable rainfall in the past 24 hours at reporting sites.
Best Outdoor Work Window: Early morning before 10 AM is your only reliable window — heat builds fast and storms fire by afternoon. If you can wait, Friday morning will likely be calmer.
Planting & Transplanting: Hold off on tender transplants today. Soils are plenty warm at 73-78°F for tomato, pepper, and squash, but wind, storm risk, and heat will stress anything set out now. Wait for the front to clear.
Watering & Irrigation: Skip irrigation today. With storms likely and excessive rainfall in the WPC outlook, let the sky do the work and reassess Friday.
For Gardeners: Stake and tie tomatoes, peppers, and tall flowers before the wind hits. Harvest ripe squash, cucumbers, and beans early — afternoon storms can bruise fruit and flatten plants. Hold off on spraying anything; wind and rain will waste the application.
For Farmers & Growers: Field workability is poor — wet ground risk plus storm timing makes today a no-go for tillage, planting, or spraying. Cut hay only if you have a confirmed dry stretch ahead, which today's pattern does not offer. Use the morning for equipment prep and scouting before storms develop.
Looking Ahead (6-10 day signal): CPC 6-10 day leans below normal for both temperature and precipitation; no drought concerns across DE, MD, or VA.
Bottom Line: Storms, heat, and wind make this a stand-down day — protect plants, skip the field, and aim for Friday.
