Raining for the last few days humidity problem

So I have little over 3 weeks left in flowering and its been raining the last 4 days. I was doing good with controling my humidity keeping it at 40% with this little dehumidifier I have in the grow room, but now it seem it can't keep up with the weather the way it is out side. It's between 50 n 55% worried about powdery mold and just the overall humidity affecting her during flowering. A few days of higher humidity during flowering won't hurt her too bad right?

It should be fine, generally keeping it at 50 is fine for the plants; I would start to worry if it starts reaching over 60.
