Castlederg -16 deg min and 19mm rain equivalent seems anomalous ?


.... from the SYNOPs in the 24hr to 1800Z (26th Dec), the minimum
temperature reported was set the *previous* evening (25th) around 21Z;
the temperature rose above zero degC between 06 & 07Z today (26th) and
rain started around 12Z today - quickly becoming occasional moderate. No
doubt the precipitation figure for the 24 hours is composed of a mix of
rainfall between 12 & 18Z and melted snow remaining in the gauge.

We're going to get quite a number of 'anomalous' rainfall data reports
from the many automatic stations dotted about - caution required :-)
