In reply to Ed Thomsett:
As Lakes Winter says, rain is forecast Weds, Thurs and Friday until the evening. Don't bother with any high crags unless, like Gimmer, they face south or south west... To be honest, you might be best somewhere like Black Crag, Wrynose, where you only have a relaxed 30min walk-in and can bin it if it's wet. Plenty of good routes there for an evening at HVS to E3 on immaculate rock, e.g. Ann's Agony, Glass Slipper, Slipshod, The First Touch, Yellow Fever, Pocket Crack, Pocket Way. Lightning Crag, 10mins walk away, also has a few more short E1/E2 gems and some hard routes (E5?). Langdale campsite is pricey but pleasant.
If you end up in Borrowdale, try Chapel House Farm campsite - more minimalist, in a beautiful setting with two pubs near. Or, if you don't need a pub, Hollows Farm has a lovely woodland feel to it and is very near Steel Knotts as well as a lot of the crags on the east of the valley, e.g. Shepherds, Quayfoot and the hard bouldering on the Bowderstone.
Burnt Crag, in the Duddon is another option... but I honestly don't think it will dry quickly enough. Someone else be may be more optimistic. Turner House Farm campsite is lovely.
