It's currently -2.5ºc and almost clear skies - looks like the forecast of -7 might well be correct. Today's maximum has been -0.4ºc, with light snow showers this morning and clearish skies this afternoon.
The Holmfirth road is probably the A6024 - which runs from near Crowden Reservoir and a road I used to drive along quite frequently. That was reported as closed earlier.
Interestingly, Rain Today are showing the rain/snow turning to snow proper as it passes through the Mansfield area, to the south of Lincoln and to the west of Grimsby.
