Sorry to bully, but trust me, I've seen snow fall all day and never stick, the temps look too high for anything exceptional other than occasional heavy wet snow for central areas and then higher eastern areas of england.
Looks zonal
Looks Atlantic driven
Looks colder
Looks dull and depressing
Those four have been said in the space of four days, that's how much it's changing!
Makes me laugh when people argue about the weather, take a sit down, read the newspapr, have a cup of tea and come back in a bit whilst you calm down. The weather is the weather!
Not sure what will happen in North Herts. My eyes are on that area of VERY heavy rain in southern France which will extend northwards over central-eastern England. As many have said, there will be imbedded activity for some, but most of it will be just unusually heavy rain for this time of year!
