    Curious about weather time

    Hi Louis, I can't pretend to know how the REX Weather Engine does all its calculations and updates, but since I'm one of those guys doing the reporting at the local airport which provides (at least some of) the raw data that REX uses to provide us with the fabulous real-world weather experience, let me mention a couple of items that will be a factor in how quickly the new weather conditions show up... As a weather observer, my principal job is to provide an hourly report summarizing local weather conditions at the time the observation is due -- for most stations, the time for filing the report is somewhere within the 15 minutes preceding the top of each hour. There are criteria which will require me to create a "special" observation between the ordinary, hourly ones -- but most of those criteria are ceiling and visibility thresholds down into the MVFR and IFR ranges. Therefore, unless that downpour you mentioned drops the visibility below 3 Statute Miles, or has the ceiling plunging below 3,000 ft, then the reporting station for the airport in question will not transmit any notice of those deteriorating conditions until its next regularly scheduled (hourly) observation is due. Unless there are other factors determining how REX generates its weather that I am unaware of (and there certainly may be), I would expect those deteriorating (or improving, or simply CHANGING) conditions to begin showing up in your flying experience the first time the REX software on your computer connects to REX servers AFTER the weather station at the reporting airport closest to you has filed that hourly report -- AND, after the report has been processed by the National Weather Service and has been disseminated to the servers REX relies on for its data. (This could take anywhere from 60 seconds or so, to several minutes.) All of that to say this: Basically, most weather data available to REX should be updated near the top of each hour -- so we should usually see our flying conditions change shortly after the top of each hour... There are exceptions to this, as some automated stations report more frequently (but usually with less -- and less RELIABLE -- data). Also, for stations with poor weather conditions, those "special" (or SPECI--as opposed to METAR (hourly)--in weather-speak) observations will show up whenever various reporting thresholds are crossed. But the change in our flying experience will still be subject to the delays of getting the data disseminated. Is that any help? And of course, I have no knowledge of any additional wizardry going on behind the scenes with REX and their servers. There might be other causes for delays or even different data -- like if they were using TAFs (Terminal Aerodrome Forecasts) instead of actual observations to drive their weather engine. (Which if I have read correctly, should be more of a problem with the OLD REX system than I think it will be with this new weather engine....) My 2¢, Drizzle
