Are you saying you've missed all the snow? The snow here in South
Oxfordshire hasn't been particularly deep, but it's obvious that other
areas have had deep snow.

No we had around 7 cms yesterday, what I'm saying is why has there
been a snow warning for this area for today (from 10.30) when it's been
dry all day.
The front coming up from the South has only reached this area in the last
hour. The snow from it is slight and patchy, surely doesn't warrant any
snow warning?


When a snow warning covers a substantial area, presumably the timing for
the warning to commence has to be the earliest time that the snow could
reach any part of the area, which could be some hours before it is
expected to reach the farther edge of the area. You could break the area
down into smaller adjoining areas and give each one its own start time,
but that could lead to a confusing plethora of warnings.
