A little late unless you postpone the trip, but shap looks alright currently. Think this is tje weather station near the summit. Wouldnt worry about Penrith as that’s one of the gritting stations so keeps the M6 clear quickly.

I could phone home in Penrith but even the weather on the M6 past shap can be different to the A6 summit so Penrith could be bright sunshine…occasionally.
