I used to be in this situation at hay time,
I used to cut just after midday so standing grass was dry and not drawing moisture, then let it wilt for the next morning and spread it as soon as I was back home at lunch time , I too took half days ,next day turn it over ,and now you are in the lap of the Gods depending on how its drying, if there is a good dry breeze I would chance making a tall row to lift it in to the airflow and minimize ground contact. If no breeze to speak of then its turn and spread and let the sun do the work. Now the dilemma, when is it dry enough as you cant keep turning it as it gets dryer and brittle the hay breaks up ( shatters) but you cant have it too damp or you run the risk of mould, I used to feel it smell it and if it would just light with a match then its rowing up time and in with the baler.
Once baled dont stack it too tight, keep an eye on it make sure it not getting hot, a little heat is OK.
Thats my way , but there as many ways as there are haymakers
Good luck , trust your judgement and not the met office
