I applied MSMA Wednesday evening and had sunny but cool days since then with dew in the mornings. Is it ok to mow now on Saturday and still get good kill?

Depends what the label states.
Changes from area to area based upon turf type, climatic conditions, other additives in the spray mix, etc.
Bear in mind C4 turf actively grows at night verse C3 turf which grows during the day. Cooler nights will inhibit the up-take of the organic arsenical compound common in MSMA which means you have to wait longer than the time stated on the label to ensure reasonable efficacy.
