Disappointing afternoon after a lovely morning. Not surprising though if one looks at the Net Wx Extra Skew-t for Doncaster. A pretty moist inversion showing that the Cu developing would spread out underneath this inversion. A maximum of 21.7C before the cloud really began to spread out under the inversion with a corresponding drop in temperature.
