Changing Weather Models

There is much uncertainty in the Long Range Weather Forecasting Models. One thing for sure is that the Atlantic is going to get a battering on Monday May 23rd and that there will be 25 to 35mm of rain in the next 3 to 4 days in some parts of the West.

Beyond that the models dont agree. Do the storms drag a lot of the bad weather up North or will a replacement secondary system become lodged over Ireland?

The first scenario has strengthened its claims on the latest model for a warm sector to end May. This wasnt at all feasible only 12 hours earlier.

Both scenarios result in a temperature differential of 10c so we would like the heat. Perhaps a safer option would be halfway between these. Maybe some warm sunny spells but some shower activity too. No doubt after the weekend it will become clearer. Weatherwise we hope too.

In order to keep posted weathergossip has it all.
