This Weekend's OM Summary
Sunshine... The Scottish Highlands actually look half decent for the weekend.
Black Clouds... Everywhere else looks a bit messy in a windy, showery, cool way.
It's feeling like a special role reversal weekend this one - for once the Scottish Highlands are looking relatively benign. If you believe MWIS, a lot to ask I know, but bear with is for now - those north of the border can expect light 10-15mph winds, the odd light shower and bursts of sunshine. Summit temperatures around 2-4˚C . And even better on Sunday when it should be bone dry with extensive sunshine.
Head further south though and things look distinctly messy. Saturday wil be so, so - think sunshine, showers and winds which could gust up to 40mph high up making teetering along exposed ridges an interesting experience. A few digits above freezing on the tops, so spot on for a bit of a windchill, but not 'that' bad.
It's Sunday when things get gnarly though. Someone's going to flick the switch that controls the giant wind-fan in the sky and you can expect 40-45 mph winds with gusts up to 60mph in the Lakes maybe with rain setting in. Gets even better in Snowdonia where winds could gust up to a gentle 80mph making movement a tad wibbly high up and giving 'severe wind chill'. Loads of cloud too and great waves of misery following on behind it.
On top of that, the further south you go, the more biblical rain you can expect. Lots of it. Particularly to the south - the BBC is already predicting the end of the world. Frankly, if you're any distance south of the border, it might be good day to wash your pets, sit in the caff or take up knitting. Make the most of Saturday or simply head for the Highlands...
The drought continues. If you want to clutch at straws, next week should be warmer and drier though with heavy, thundery showers on some afternoons. Feel better now?
Useful Weather Resources
Mountain Weather Information Service
Part funded by the Scottish Government, MWIS has detailed downloadable forecasts for all the major Scottish mountain areas plus the Lakes, Snowdonia and the Peak District / Yorkshire Dales. Includes wind, temperatures, visibility, precipitation and more. Can verge on the pessimistic and the combined Peak/Dales effort is a tad confusing at times, but a great resource for checking weather in the hills.
Met Office Mountain Forecasts
Another excellent weather resource as you'd expect from the Met Office. It has fewer Scottish areas than the MWIS version, but otherwise provides a similar level of detailed analysis and also scores by having individual Dales and Peak District sections plus coverage of the Brecon Beacons.
Lake District Weatherline
Run by the Lake District National Park, Weatherline - which can also be accessed by phoning 0844 846 2444 - carries the detailed Met Office Lakes mountain forecast all year round, but really comes into its own over the winter months when it features daily reports from a fell-top assesor who climbs Helvellyn every day and writes a report on snow and ground conditions on the high fells. Invaluable if you're heading out in winter conditions.
Met Office General Forecast
Does what it says on the can, but is well worth using both as a handy overview of the country as a whole and, for the detailed regional forecasts, particularly if you're heading to an area not covered by the mountain specialist sites. Well worth a browse if you have a general interest in meteorology as well for some of the wider ranging weather articles.
BBC Weather Pages
The BBC uses Met Office data, but presents the information quite differently. It's real plus point however, is the online iPlayer forecast which generally gives a useful overview of what's happening with animated graphics that even the densest viewer - us - can understand.
An alternative option for general forecasts, Metcheck still has a bit of a weather enthusiast vibe to it and you find detailed hourly forecasts for post-coded locations. It does have a tendency to disappear off the face of the web at times and also generates the odd bizarre data errror when models go awry, but they're usually pretty obvious - 200˚C temperatures and the like. Many of the original enthusiast features now appear to be dead.
Scottish Midge Forecast
Genius page also available as a smartphone app which uses midge monitoring stations for forecast the concentrations of the evil little blighters across Scotland during the peak midge months. In practice, Glencoe, Fort Willam and the Western Highlands cop the worst of it on a consistent basis, but if you're keen to avoid or at least get an idea of how bad things are likely to be, this is the site to visit. They're also behind the excellent Smidge repellent.
Scottish Avalanche Information Service
Avalanches are more common that you might think on Scottish hills and the SAIS provides excellent daily forecasts of avalanche conditions across five main Scottish mountain areas. Alongside those are blogs from the SAIS observers, often with recent photos which give excellent background to the actual reports. Bear in mind that snow conditions can change rapidly, so check the latest forecast before heading out. Also posted prominently in strategic local spots and available on your mobile.
Disclaimer Mountain weather and conditions are by their nature unpredictable, so while the forecast links above and our summary will give some idea of the outlook on the hills, things can change quickly, so you should always use them as a guide to what the weather may do rather than as a definite. Be aware too that conditions can vary massively between the valley bottom and the summits and dress and equip yourself accordingly.
