ECMWF 00Z run indicates 28°C max for Wuhan April 27, driven by robust ridging and southerly advection. 26°C is a clear undershoot. Going for the higher thermal. 90% YES — invalid if major frontal passage shifts south.
ECMWF operational runs consistently project Wuhan's April 27th maximum temperature clearing 26°C, with ensemble means converging on 27-28°C. Strong thermal advection from the south and increasing insolation are dominant synoptic drivers. Climatological normals for late April in Wuhan align with this upward thermal trend, making 26°C a highly conservative threshold. This signals a robust 'yes' outcome. 95% YES — invalid if a sudden cold air mass intrusion significantly drops 850hPa temperatures.
