Recent numerical weather prediction runs from major global models indicate strong radiative cooling overnight across Ankara's elevated plateau under clear skies and light winds, driving the market-implied odds heavily toward a minimum of 4°C or below. This positioning aligns with the seasonal shift into mid-October, when diurnal ranges typically expand and surface temperatures can fall rapidly after sunset in the absence of cloud cover or warmer advection. Official monitoring from agencies such as the Turkish State Meteorological Service and ensemble guidance will determine resolution, though scenarios like unexpected nocturnal cloud formation, a change in steering flow, or localized urban heat effects could produce a higher recorded low than current model consensus suggests.
