Live Istanbul (LTFM) runway temperature & next-METAR nowcast

Istanbul straddles the Bosphorus where Black-Sea air keeps summer highs humid and capped; the new airport (LTFM) sits on the northern coast. Settles on the LTFM METAR (NOAA); this beta tracks the Turkish Met Service's airport station (0.1 °C, sub-hourly) ahead of it. polyweather.today tracks minute-by-minute runway temperatures from Istanbul Airport (LTFM) (LTFM) — the same sensors behind the official METAR — and turns the trend into a next-METAR nowcast, so you can read where Istanbul's temperature is heading before the next METAR prints.
