What changed
The latest NWS observation at Des Moines International (KDSM) recorded:
- Temperature: 75.2°F
- Dew point: 57.2°F
- Wind speed: about 10 mph
- Barometric pressure: 30.12 inches of mercury
These readings are a single-station snapshot, not a statewide average or a forecast.
Why it matters
Mid-70s air temperature with a dew point in the upper 50s means the air feels comfortable — not sticky. That spread (roughly 18°F between temperature and dew point) suggests relatively low humidity for late May in Iowa. For corn that's pushing through V3–V5 and soybeans in early vegetative stages, warm daytime temps in this range support steady growth. Light winds near 10 mph and stable pressure around 30.12 inches of mercury point to settled weather at the time of the reading.
Keep in mind this is one station at one moment. Conditions across Iowa's 99 counties could vary, especially in areas that have seen recent rain or cloud cover.
What to watch next
- Overnight lows: If nighttime temps stay above 50°F, that keeps soil warm and crop development on track. Worth watching local forecasts.
- Dew point trends: A dew point climbing into the mid-60s or higher would signal more humid air moving in, which could mean rain chances ahead.
- Pressure changes: A drop from the current 30.12 inches of mercury could signal an approaching front. Steady or rising pressure generally means more of the same.
