Reasons for This Assessment
- Wind: 14 kt. 80m wind.
- Gusts: ≥14 kt. surface gust 11 kt < 80m sustained — floored to sustained (gust at altitude cannot be lower).
- Visibility: 15 SM. flight visibility. Part 107 weather limits.
- Ceiling: No ceiling indicated. cloud clearance. Part 107 weather limits.
- Temp: 15°C. battery-friendly.
- Precip: 0.0 mm/hr. dry.
- Kp: Kp 0.3. quiet.
Planning aid only. This is not a substitute for an official briefing or permission to fly. Check the launch site, airspace, NOTAMs and restrictions with FAA B4UFLY services. The remote pilot makes the flight decision.
The altitude wind is the existing 80 m product. It is not a measurement at 400 ft. Wind at your flight height can differ.
Default Limits and Data Sources
VectorWX uses its existing drone score. Sustained wind limit: 17 kt. Gust limit: 22 kt. Temperature range: -10 to 40 °C. Kp reference limit: 5. These are app defaults, not FAA wind, temperature or Kp rules. Check the aircraft manual.
14 CFR 107.51 requires at least 3 statute miles of flight visibility from the control station, 500 ft below clouds and 2,000 ft horizontally from clouds. The app uses a 900 ft ceiling reference for a flight at 400 ft AGL. A model ceiling cannot check horizontal cloud separation.
Source: NOAA HRRR for surface weather and 80 m winds; NOAA GFS for visibility and ceiling, through the VectorWX grid feed; NOAA SWPC for Kp. Values are checked at least every 30 minutes on request.
Model initialization (UTC YYYYMMDDHH): HRRR 2026102907; GFS 2026102900.
What These Conditions Mean in St. Louis
This forecast samples St. Louis at 38.6270° latitude and -90.1994° longitude. It covers the city-center grid cell. It does not describe every launch site in the metro area. Around the Mississippi and Missouri river lowlands, compare the open flight path with the sheltered place where you stand. Buildings, trees and terrain can change the wind along the route. Check conditions at the launch point and the planned landing point.
For the forecast valid at Oct 29, 2026, 4:00 AM CDT, the current surface wind is 4.8 kt. The 80 m wind is 14.3 kt. The altitude wind is 9.5 kt stronger than the surface value. The score uses the altitude wind when it is available. The surface gust feed reports 11.5 kt. The score can raise its effective gust floor to the altitude sustained wind. This lower bound is not a measured gust at flight height.
Visibility in the St. Louis forecast is 15.0 statute miles. The model indicates no limiting cloud ceiling. Check clouds along the entire flight path. Part 107.51 sets flight visibility and cloud separation requirements. A ceiling forecast alone does not establish the horizontal distance to a cloud. The airport observation at KSTL is a useful nearby comparison. It can differ from the launch site and from this forecast grid.
The forecast temperature is 15.0 °C, and precipitation is 0.0 mm/hr. Use those values with the aircraft operating manual and battery instructions. The Kp reading is 0.3 , observed at Oct 29, 2026, 3:50 AM CDT. Kp describes planetary geomagnetic activity. It does not measure interference at a specific launch site. The existing VectorWX engine gives this set of inputs a Go assessment. Read each reason above before you use that result. A weather assessment does not grant airspace access or confirm that a flight is lawful.
