Looks like mostly rain tomorrow for Exeter and then a rapid change to snow around 3pm looking at that large white blob as forecast by BBC but by 6pm the precipitation would have already cleared but looks like it may linger in central and south eastern areas: - He said accumulations of 2-5cms even at lower levels. However, It depends how heavy precipitation will be for any evaporative cooling at 1500z.
Looks like the south east is where the snow will be the most significant with cold air to the north from another font colliding with the low coming in from the west moving across all of southern England! So looks like a brief transient snow event in Devon between 1500 and 1800 hours but snow lasting perhaps between 1800 and 12:00 am in many parts of the central southern and south eastern areas.
Looks like the cold air has already under cut that warmer sector as it's already snowing as far south as Plymouth by 1500 when most of N.E Devon and East Devon, south SOmerset and west Dorset still sees rain - I will keep you all updated here in Devon tomorrow as the band of snow (if any) from same frontal system will hit Devon first.
However, BBC graphics (as always) are really poor. So will check Met Office rainfall radar,.
