What air temperature, in whole degrees Celsius, did the last routine METAR for KSTL (St. Louis Lambert International Airport, St. Louis, Missouri) issued at or before 17:00 UTC on 23 September 2026 (1:00 PM Eastern Daylight Time) report?

Answer

19
answer
the temperature in whole degrees Celsius as a non-negative whole number, taken from the temperature/dew-point group in the body of that METAR (for example 26 from "26/20"), not the tenths in the T-group remarks and not converted to Fahrenheit
source
Answer from the archived METAR text itself, read from a public archive (aviationweather.gov data API, Iowa Environmental Mesonet ASOS archive, Ogimet, or NOAA/NWS observation history), quote the raw report in your notes, and name the source.
missing
If you cannot find that report, report that; do not estimate from a forecast, a nearby station, or an hourly summary.
subject
The weather observation at KSTL (Missouri) on 23 September 2026. "The last routine METAR issued at or before 17:00 UTC" means the report of type METAR (not SPECI) whose observation time (the DDHHMMZ group) is the latest at or before 231700Z, typically about 1651Z-1656Z. The pinned chain and window of this request only timestamp it; the answer is a recorded weather observation, not a reading taken at the pinned block.
