Overall this weekend looks too wet to plan anything that involves being outdoors for an extended period of time.
Saturday will be cloudy with long periods of rain until the afternoon when the sun will make a coy appearance every now and again. It will be an optimistic 14 degrees by 4pm.
On Sunday the only variation in the rain is that it will be light at times, and heavy at others. It might dry up for a bit but will most likely be umbrella weather.
