A retired police constable turned climatologist claims snow will fall all over the UK this winter! I talk about this in more detail on my blog here but thought I would put it in general discussion as well
The Met Office have already spoken up and said that he doesn't use a scientific way of forecasting and that winter will be cold, it's winter. Ha.
Anyway he goes onto say that Christmas day will be snowy for the north but no luck for the south. Apparently though the south of UK will see large amounts of snow into the new year and temperatures will drop into 5-. He says he is hardly ever wrong so who knows, we might be in for some luck here in the UK.
I personally can only remember one year that we had amazing snow here in the south of the UK. It was great. Either way fingers crossed.
Hi - I was wondering if someone could help with a question on the best forecasting site, app or API for forecasts i want in the UK. I need approximately 80 forecasts returned for a set of co-ords all at the one time preferably in tabular form. Metcheck displays multiple locations for things like UK seaside but if anyone knows of a way of extracting this info in to a table then this would be very helpful. thanks for any help

Hi everyone, have decided to start up a separate topic to look more closely at expected rainfall accumulations in the days ahead. It's a concern that more new floods are possible if not likely through this weekend and into next week, this coming from several large scale weather systems and possible Atlantic storms hitting the UK and ROI over the next 7 days at least, it's likely that some breaks in the rain will occur at times though.
I'm not going to hide the fact that severe floods in new areas are possibly on the way I say possibly even if I think likely, which I do.
Below I've put on a rain alert map created from precipitation data models of which the one's I have access, please use my map as a general guide of where the heaviest rain could be accumulated over the next 48hrs or so, please do allow for some small adjustments do not take the map as 100 percent set in stone, usually the expected accumulations of rainfall may be more or less in any one area and exact locations can change, I might not be able to update map.
(Map can be shared where you like)
Map expires MON 0300hrs - January 4
W = on the map this means that I am watching for upgrades of 30mm or more.
Light yellow + W =30mm - rainfall may get accumulated up to 30mm but may upgrade to 40mm for a level 1 so is under a watch zone.
Yellow = 40mm - 50mm accm rain
Orange = 50mm - 80mm accm rain
Red = 80mm - 100mm accm rain
Dark red = 100+ accm rain.
Many areas seeing rain this heavy at times some very heavy and prolonged, expect 10mm-25mm generally.
Some of the largest rainfalls likely to occur over higher ground.
For the winds associated with these weather systems/storms likely gale or severe gale at times please see other threads and warnings.
Please post anything related to rainfall forecasting, model ppn data, alerts and warnings, your own rain maps and forecasts.

I've just written a blog hopefully explaining more about how the Met Office create their weather warnings and how the 3 levels now include likelihood of severe weather and the possible impacts.
Did you know this about the impacts?
Is this the right way to go for the public?
With this explanation do you feel the warnings are now more helpful to you?
The Matrix is now a key part of the warning, but is there anyway to show high impact, lower likelihood
or medium likelihood of low impact event from just the 3 colours?
