Most pilots are dedicated aviation weather geeks because, at the least, their lives, and those of their passengers depend on the crew’s current knowledge of what Mother Nature is doing at Chicago Executive Airport, the flight’s destination, and everything between them. To the list of the weather information sources that pilots frequent, the National Weather Service has added LAMP, for Localized Aviation Model-Output-Statistics (MOS) Program.
In other words, LAMP focuses on more than 1,500 airports (including Chicago Executive) and provides forecast guidance on “sensible weather elements.” Sensible means they are “perceivable elements” of weather, such as temperature, dew point, wind speed, direction, and gusts, sky cover, ceiling, visibility, obstruction to vision, precipitation and type, lightning, and convective activity. And as the capture from the PWK page shows, pilots can select the sensible elements they want to see. They can also get the same info in text form, if they are so inclined.
What makes LAMP a worthwhile weather product addition to any pilot’s weather briefing resources is that it is totally automated. On the downside, it might not be as accurate as a forecast tweaked by a human meteorologist, but the LAMP graphic is updated hourly. This hourly update incorporates the latest surface conditions to create hourly forecasts that look up to 25 hours into the future. Regardless of who or what is predicting the weather, no source is 100 percent, so LAMP pairs nicely with human-involved weather products such as a Terminal Aerodrome Forecast (TAF).
At each airport’s LAMP page pilots can access fresh forecast info for the next 24 hours. The page delivers both “categorical and probabilistic forecast guidance” on the given elements, and using the selection click-boxes at the top of the page, pilots can extract the information they want. When selecting the ceiling and visibility category forecast, it includes a “conditional forecast” that takes precipitation into account. “This data attempts to account for some of the temporary fluctuations that occur in flight.”
