Everest Forecast 12 may
The 13th and the 14th the wind on the highest levels of the mountain is still strong (30-40kt=60-80km/hr). From the 15th till the 18th wind decreases to 10-20kt, after the 18th again becoming more than 35-40kt.
From the 15th the air is getting unstable enough to trigger a few snow shower. At this stage it looks like those showers will be rather limited and not too heavy.
So the 16 and the 17th look like a rather good weather window to go for.
