OM's straight talking round-up of this weekend's mountain weather prospects - Bank Holiday special...
Bank Holiday Mountain Weather Round-Up - June 2-5, 2012
Every Friday we bring you links to all the best mountain weather resources on the web, so you can check specific conditions in all the UK's leading mountain areas this weekend plus a quick OM summary to give a general idea of what's happening this weekend. Weather in the hills can change fast, so check back for the latest forecast before you head out.
This Weekend's OM Summary
Sunshine... Light winds, sunny spells, substantial dryness over the weekend.
Dark Clouds... Slightly chilly, Sunday wet in Wales, heavy showers from Tuesday.
It's the first week of June, it's a Bank Holiday weekend, a long one at that, and Wimbledon is apparently imminent, so in the context of all that, things aren't looking that bad, at least for the first half of the four-day weekend.
For starters, the weather folk agree that winds will be pleasantly light at around 10-15mph and the weekend will be mostly dry, with the exception of Wales, which - if you believe the Scottish-based guys at MWIS - will cop a band of static rain, while the rest of us sizzle in single-digit summit temperatures. Northern Snowdonia may be okay however... The Met Office concurs.
Speaking of summit temperatures, they're not looking good. Maybe as high as 8˚C in North Wales on Saturday, but as low as 0˚C in the 'Gorms... So don't dog out that strappy walking dress just yet. This week's MWIS code for sunny spells is 'intermittent sunshine' bring back the 'patchwork of sun' days is what we say.
But basically the first couple of days are looking okay if not stunning. From Monday things may get iffier. Pressure will drop with rain tap-dancing across the country. That may possibly happen on Monday, but Tuesday looks the more likely scenario according to MWIS anyway with heavy showers 'across all mountain areas'. We'd check back later in the weekend though, timing is uncertain, so the rain may not actually arrive until late on Tuesday.
And now the usual bad news - according to the Midge Forecast everywhere scores negligible to moderate bar Glencoe where the midgies are at maximum '5' or 'Nuisance' levels. We know a better word for 'nuisance', but we're not allowed to use it.
Have a good one.

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.
Metcheck
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.
