As you know I get quite agitated by some of the analyses that the UKMO come up with in their six hourly fax charts. At the moment they have a whole bunch of fronts of one sort or another queued up to the west of IONA. The first one of which was a warm front, which at midnight was aligned north-south from St Kilda* in the north to Valentia in the south. The front itself had been first identified at 06 UTC yesterday (17th), and hadn’t previously been marked as a weakening feature (frontolysis), nevertheless it had been completely omitted from their 06 UTC analysis this morning, which was quite surprising as it was responsible for a broad band of rain from Cape Wrath down to Anglesey in the weather radar. Some fronts in the UKMO analyses in my opinion don’t exist and the analysis in some respects becomes more of a nephanalysis, but on this occasion when they were 100% correct about the warm front at 00 UTC, which by 06 UTC had ceased to exist, and really should have been drawn where I’ve added the red line. All I can think is that they forgot to add it to the finished product and this analysis needs a correction. It will be interesting to see if they do that and what the 12 UTC analysis chart looks like.
It also seems to have got “Hello There” Louise Lear foxed in her forecast graphics this morning on the BBC which don’t seem to line up with the reality of the situation.
