Yes, I agree. Snow in March, at least down here on the Sussex coast always feels like a wasted opportunity though, with a rapidly strengthening sun and longer days.
The chances of snow down here at very very low, and zero for the majority of the low's passage across the UK. We might get a cold waft as it departs, but even that is not the most likely scenario. Most GFS ensemble members have it remaining relatively mild with only 2 or 3 developing cold air...
The local TV forecasts have mentioned patchy drizzle in places, esp over hills and near coasts. Findon fits both categories. I'm sure you've lived round here long enough to expect light drizzle quite frequently in warm winter SW winds.
These are both showing the same data- i.e. the most recent GFS Operational run. Sadly it is in the minority (even with it's own ensemble) showing snow along the south coast. It's not impossible, maybe 25% chance. Most models have the precipitation either in the Channel or over France.
I'd say the odds are against it, but it's not impossible. For Sussex to get disruptive snow (MetOffice terms) requires a number of things to happen just right:
1. The cold air arriving from the north Sunday / Monday needs to have enough time to get right down into the South, and be properly...
I only post on there rarely, it's more of a spectator sport!
Unless you frequent the forums, you wouldn't realise just how many 'near misses' we have, be it snow, or heat-waves or thundery breakdowns.
