Not convinced the amber warning is warranted if I'm being honest - certainly not to lower levels.
If anything the set up for tomorrow is worse than it was last weekend - very marginal DP's and upper temps - ground temps don't look to be anything near what YR.no prog - I'd guess if today is anything to go by, to be around 1-2c, which coupled with a -1c dp (for the central belt) doesn't really anything to me, other than sleet then rain.
