Altitude weather delta

High 5,549 m minus low 4,007 m is 1,542 m of relief on this record. A standard tropospheric lapse of 6.5 °C per 1,000 m implies about 10 °C cooler at the high point than the valley, all else equal.

That is a model (International Standard Atmosphere environmental lapse), not a forecast and not a trail-closure. Wind, snow, and storms stay in Hazards.
