🌱 US Weather Warriors GrowCast — Friday, July 17, 2026
Hot, humid, and unsettled — scattered thunderstorms and heavy rainfall potential ride in on a summer airmass.
Today's Weather Snapshot: Lows near 71°F, highs from the low 80s at the coast to around 92°F inland. Thunderstorms possible with locally heavy rain; PoPs run 60–88% up the I-95 corridor. Winds near 10–18 mph, gustier under storms. Humidity high — dewpoints muggy and air feels oppressive. Air Quality Alerts in effect region-wide from Canadian wildfire smoke.
Soil & Recent Rainfall: DEOS 2-inch soil temps averaged 78.8°F (74.0–82.3°F range) across six stations. Past 24 hours brought 0.00 inches at reporting sites; topsoil at DDFS and DAGF running dry ahead of today's rain.
Best Outdoor Work Window: Early morning — before 11 AM — is the safer window ahead of afternoon storms and peak heat. If storms fire early where you are, shift the sensitive work to Saturday morning.
Planting & Transplanting: Rule label says Delay. Soils are plenty warm for anything warm-season, but incoming heavy rain plus Elevated thunderstorm risk means tender transplants will get beaten up. Hold seedlings under cover until the storm pattern breaks.
Watering & Irrigation: Skip irrigation today. With heavy-rain guidance and PoPs up to 88%, let the sky do the work and reassess Saturday based on what actually fell at your site.
For Gardeners: Harvest ripe tomatoes, squash, cucumbers, and beans this morning before storms bruise them. Shade cloth over lettuce, chard, and any lingering cool-season greens will slow bolting through the heat. Stake tall crops now — gusts under storms will lay them over.
For Farmers & Growers: Field workability is Poor and wind is Caution — hold sprays; drift and washoff both work against you today. Don't cut hay into this pattern. Use the morning for scouting, equipment prep, and irrigation checks rather than tillage or planting passes.
Looking Ahead (6-10 day signal): CPC 6–10 day leans above-normal temps and above-normal precip; Drought Monitor shows no drought across DE, MD, or VA.
Bottom Line: Work early, harvest what's ripe, and let the storms pass before touching soil or spraying.
