Settling readily on vegetation at 250m, possibly an inch or so on the Lickeys. Here at 150m, just slushy deposits. The difference in a 30 second journey down the hill was quite dramatic so the division line is quite sharp.
Freezing level should be at around 300m going by that. Freezing level will drop tonight to around 100m, so 5-10cm looking likely for anyone above that line and up to 15cm above 200m would be my educated guess. Below 100m, particularly in the far south of the region, probably not looking at too much due to the higher dew points.
