Recent weather model consensus from sources such as GFS points to a daytime high near 19°C in Warsaw on October 5 under partly cloudy skies and moderate westerly flow, establishing the leading market-implied probability. Stable high pressure and limited cold-air advection from the northwest have kept temperatures above seasonal averages, with afternoon mixing and light winds supporting modest warming before any evening cooling. Traders appear to weigh these stable synoptic conditions against typical model spread in short-range forecasts, where small shifts in cloud cover or wind direction could tip the maximum between 18–20°C. Updated runs ahead of the date will refine resolution criteria for this single-day temperature observation.
