Obviously we're all missing GWs regular input and (no offence meant to anyone else) it doesn't quite seem complete at the moment, although we're lucky to have Art's daily updates.
I thought I might take a pip at mid-month then. Not truly representative of course, but just as a feeler I looked at preds for Leicester which is very roughly in the middle of the triangle. We've had 8 days so the next 8 days are estimated by the Beeb to have the following averages:
7 5.5 5 5 3.5 6 6 6 (at time of posting).
I make that an average of 44 ÷ 8 = 5.5.
Coupled with the current 8 days which Art has posted as 7.9 and we have a 16 day average un-adjusted of about 6.7. I'll need the second half-month to be bloomin cold to get close to my prediction!
