LAUNCH CODE AVIATION FORECAST
Nearest available reports, up to two hours old. Nearby observations may differ from conditions at your launch site.
Three-hour spacing throughout. Opening columns use NBH; NBS begins Oct 11 03:00 UTC. NBH issued Oct 10 22:00 UTC. Missing NBH hours or fields show N/A. Hourly accumulation values are not substituted for three- or six-hour values.
Supplemental guidance — not a go/no-go decision. Do not rely on this page alone. Obtain a preflight briefing and verify actual conditions. Favorable symbols and phrases only reflect your selected limits. Pilot responsibility & terms

Flight category uses the more restrictive of forecast ceiling (CIG) and visibility. Lowest cloud base is shown separately and is not substituted for ceiling. Both inputs must be available to assign a category.
Rows marked 1 hour describe only the hour ending at that column. Six-hour blocks cover the displayed columns ending at their valid time. Edge blocks may cover only part of the displayed table; hover to see their full time range. A six-hour precipitation limit applies to all covered columns, without dividing its probability or amount. Other personal limits compare the forecast value at each column time, not every moment between forecasts.
Air Sports Flying Conditions compares only the limits you enable: a thumbs up means all selected limits are met, a thumbs down means at least one is exceeded, and a question mark means required data is missing. Click a symbol for details. This is a personal forecast comparison, not a flight clearance.
Snow, freezing-rain, sleet, and rain probabilities describe precipitation type if precipitation occurs. Snow and ice accumulation periods are specified in each row. Mixing height and transport winds describe the atmospheric mixing layer, not thermal strength or winds at a specific flight altitude.
Curves connect model forecast points for readability and do not add intermediate forecast values. Wind arrows point toward the direction of travel; compass labels show where the wind comes from. Wind chill and heat index are shown only in their applicable ranges. A dash in those rows means not applicable; N/A means required data is unavailable. Compare this guidance with observations, official aviation forecasts, and your preflight briefing.

Do not use this page as your only source for a flight decision. Launch Code provides supplemental, automated weather guidance. It is not a substitute for a complete preflight weather briefing, current observations, applicable aviation forecasts and advisories, or your assessment of actual conditions at the launch site and along your intended route.
You are responsible for deciding whether to launch, continue, divert, or land. Fly only within your training, experience, personal minimums, aircraft limitations, and applicable operating rules and qualifications. Verify the forecast location, issue time, and valid times. Recheck conditions before departure and throughout the flight; delay or cancel when conditions are uncertain or unsuitable.
Forecasts may be incomplete, delayed, incorrect, or different from the weather you encounter. Conditions can change rapidly. Missing data or a hazard not shown on this page does not mean that the hazard is absent. Air Sports Net does not guarantee the accuracy, completeness, timeliness, or suitability of this guidance for any flight.
A favorable symbol, color, or phrase is not a recommendation or authorization to fly. Personal-limit results compare only the available forecast values against the checks you enable. They do not evaluate every risk. Phrases such as “Go Fly” are optional display captions, not operational advice.
Obtain a preflight briefing and consult additional aviation weather sources. In the United States, visit Flight Service or call 1-800-WX-BRIEF. Use of this forecast is at your own risk and is subject to the Air Sports Net Terms of Use.
