We’re having issuing uploading some images, will take a look at this.
The cold air associated with the event on Wed/Thu sure looks less defined than the 1993 / other “classic” undercuts, so the snow line will hang around at altitude higher. From experience this event may be largely restricted to hills. However, given a more optimal pivot there is a possibility snow heavy wet snow to low levels west of the M6 & a covering east due to mixing of a shallow maritime layer near the sea.
The problem with the Hirlam/Arpege is that there’s no pivot, the WRF produces a much more pronounced pivot which is also shown on the GFS. Those below 200m ASL should keep a close eye on the pivot as I reiterate.
I was referring to the UKMO 12z 120 hr chart rather than Wednesday/Thursday event. 🙂
