This is the 2nd run of today, but as it shows a significant change to Scotland, I thought it would be worth showing. As you can see, the isobars are less pronounced, indicating light winds for Scotland. The tighter the isobars, the stronger the wind, so the rest of the country remins very windy.
Isobars are the black lines on the chart. Each line represents a 2mb change in pressure.

Low pressure systems rotate in an anticlockwise direction, so as the low is in the North Sea, you can see that winds will be from West to East. (Highs rotate in a clockwise direction).

Rain is indicated in the colours. Dark blue upto 20mm, light blue upto 10mm, dark green upto 5mm in 6 hours.

You'd have to get past me first

Seeing as you lot are obsessed with snow (aren't we all) I found this.

This chart is the closest I have for now. (reports of snow across northern Scotland tonight) This is the midnight forecast for Tues/Wed 17th Jan.

See the blue dotted line across the northern edge of Scotland. This is the 528
DAM line (its a thickness of air measurement) but as I mentioned earlier, its what is associated with snow. Basically, if you have that and you have rain, 9 times out of 10 it will fall as snow or a wintry shower.

Of course! Are you going to help?

Should it ever snow here again I think we all have an obligation to take photos, make snowmen and take more photos... The gallery is a handy place for them too
