Considering the Surface Pressure Chart (http://www.metoffice.gov.uk/weather/uk/surface_pressure.html), we get an increase in the wind from morning to afternoon as a low pressure will be moving in. Using the rough rule of thumb that for every isobar covering the uk that is 10mph of wind we get the wind increasing from 30mph (top image) to 60mph (bottom image):
Then if we consider the more detailed MWIS forecast (http://www.mwis.org.uk/wh.php and below), we can see that the winds range from 30mph to 45mph in the morning to 60mph gusts in the afternoon. In this case the rule of thumb was relatively accurate but it is a very rough estimate most of the time. There are also snow showers forecast and the cloud base and freezing level at 700m with only a 10% chance of a cloud free munro.
It will most likely be a taste of what is to come in the winter, so everyone remember to suit up and be nice and warm. We will play it by ear as to what we do when as we can not estimate how the group will respond to the conditions or what the exact conditions will be like.
