Training camp is always kind of a crap shoot as far as weather and flows. Right now the forecast is looking like around 70 degree and mostly sunny high Sat. and Sun.
As far as clothing... More of higher quality (full on drysuit) is always better. That being said I know most people have a budget and drysuit's are not usually available to new paddlers. It sounds like you will be similarly equipped as most people at training camp and should be ok. That being said, always error on the safe side and if you are getting to cold inform your instructor as soon as possible and they will make sure you get into an environment that will warm you up and is safe.
I will be helping out Sunday, I hope to meet you.
