I just spent the weekend there...there is definitely snow on the higher fells...However, I spent the weekend walking some of the very boggy Northern/Central Wainwrights (Carrock Fell, High Pike Nthn, Bleaberry Fell, High Tove, High Seat, Armboth Fell) over 2 days. The last four in particular would be awful in warmer weather, I honestly couldn't imagine doing them
...but on the weekend the bogs were frozen and it was a delight to just stroll over them.
If you are a Wainwright bagger, I reckon there's no better time to knock these off
