Decoding rf signal from a Nexa temp station

I'm capturing this signal from a Nexa weather station - reports temp and humidity between 20 and 90%. I've captured the signal but haven't created a sketch to accurately capture the signal
From audacity here's a portion of the signal (attached) - it seems to be formatted as a header section then repeats the data 5 or 6 times

Any ideas for coding the arduino to capture this particular signal pattern?

You need to decipher the actual bit encoding from an expanded version of the screen shot you posted. It has been done many times, but here are a couple of links:
