F^S Read what Will said LJ, It is not showing on the radar because it is still developing aloft. It is an upper warm front and what is happening is that snow is falling and then evaporating. The evaporation will moisten (and cool) the atmosphere and eventually the snow will descend to the surface, so I would expect a sudden increase in radar activity in a few hours from now. This has been well signalled by the models which do have the correct dynamics and physics routines to do this quite well. As always meteorology is a 3-dimensional process and forecasters have to think in 4-D all the time! In the past without models such situations may have caught forecasters with their pants down as nothing is showing on surface reports and then all of a sudden - it's snowing! Will |

But surely we've been talking about the heavier forecast stuff at least 7cm
