It is hard to believe its mid May with a forecast that is more like winter. I find it very cold just now many will be champing at the bit to get out. Please have a re look at the weather forecast form any of the mountain weather sites. MWIS and MET office have some great advice. This is todays for my local hills the Cairngorms with snow and whiteouts forecast. So if your venturing out just get some of that winter kit back in, it makes sense?
MWIS – https://www.mwis.org.uk/
Low pressure rotating slowly across Britain brings a poor day to most places. Rain frequent or rarely ceasing; snow and whiteout across the Munros, focused on the Cairngorms, whilst western Scotland will be drier. Windy, gale or locally severe gale force for periods.
Headline For Cairngorms NP And Monadhliath
Windy, cold; severe gale high tops. Rain, upland snow & whiteout.
How Windy? (On The Munros)
East to northeast in the range 35 to 50mph, sometimes 60mph higher Cairngorm plateau. Wind speed table below.

Effect Of The Wind On You?
Be prepared for arduous or difficult walking conditions across the hills with significant buffeting and wind chill.
How Wet?
Rain and upland snow rarely ceasing
Almost constant precipitation will drive in from the northeast through the day, falling as snow above 800m, later 600m, leading to periods of sustained whiteout across the tops, extensively lying on the higher Munros. Least precipitation around Glen Garry and west of Dalwhinnie.
This is only part of the forecast so always be prepared to change your route and go lower leave the mountains for another day. If you change your plans please tell someone no matter how experienced you are where you are going.
