Andy the MWIS forecast for the Cairngorm NP does mention a chance of snow showers over the peaks

Anyone fancy a bivvy on Macdui to find out? 



Edit: of course, snow falling above 4,000ft in Scotland in summer only happens more often than not .....

It is even more common above 5000ft I believe. 😉

Precip type radar is picking up sleet over the cairngorns!


Also its a shame the band of rain is not in Scotland, if it had been I'm sure we would have broken the record. 10-13C under the rain with the superzero uppers, in N scotland its 9-12C with the subzero uppers but without the rain. You need both.


 


Still opportunity for cold temps tonight.

Still not sure why this is surprising. To see what conditions may be like on Cairngorm you only have to track the 850's and 0'c surely isn't that rare, even in July?

Generally speaking July-Early September is snow dry for the whole UK even the mountains.

I'm a little miffed to where these cold temperatures are suppose to be? Is it just Scotland??

It's currently 22C with a breezy mild feeling NW wind.

It's rather cloudy but there are some breaks allowing the sun to occasionally shine. When the sun comes out it feels very warm.

I recall a few July days that did not reach 10C usually during a rain event with a Low sat in the North Sea + northerly winds.

Four lives on the North York moors so is understandably very cool. It's quite a bit warmer closer to sea level.


it's 11.4C right now which is very cool for the time of night but a few cool nights in July is par the course really. Might get down to 9C at this rate which admittedly would be our first low below 10c in exactly 2 weeks. Today was also our first high below 20C in exactly two weeks, so..

I did hear on Radio 4 this morning that the temperature got down to +0.6 C at Katesbridge, Co. Down last night. I can't seem to find anything online to confirm it, but I seem to recall the announcer saying that it was a record low for July for N.I. If this is correct(and at that hour of the morning it's entirely possible that I dreamed it!), Quantam will have been vindicated in opening this thread

Feel I should resurrect this thread. Northerly winds are going to be unusually frequent until the months end at least, and with the Atlantic arctic unusually cold some more 0C 850hpa incursions look probable. When combined with rainfall (which is likely given the LP domination) we have a lot more chances to attempt to break the records (either lowest july maximun or lowest july minimun).
