Times are UTC (Z); the time after a slash is the local time at the airport. Weather and runway data come from the NOAA Aviation Weather Center (aviationweather.gov) and are refreshed here every few minutes; the plain-English summaries are generated by cwsi.net and may simplify, so the raw METAR and TAF are authoritative.
