**Additional Information**

On the Tuesday of the report the forecast suggests that the temperature on the summit will be just below freezing at times, but several degrees above freezing at other times. There will be a tendency for it to be very cold overnight, and much warmer during the day, with a general tendency for it to warm up towards the end of the week. The temperature at the summit is forecast to be as low as -2ºC (feeling like it is as low as -11ºC at times).



With a forecast for a dry week any snow seems very unlikely from the forecast on the day of the report. However it may be cold enough for freezing conditions to develop overnight, especially on Tuesday night and into Wednesday morning. Freezing conditions appear less likely later in the week, but cold temperatures and frost are possible under clear skies in sheltered areas.

With strong easterly winds and clear periods, although it can feel very warm out of the wind in full sun, it could also feel very cold in the wind at less sunny times.
