You are declaring your mPrecipChance incorrectly. Double is a Java primitive variable type which can hold very large (or small) numbers. The maximum and minimum values are 17 followed by 307 zeros. You can read more about Java primitive data types here.
You declare them in a similar fashion as strings and integers. The line of code for this challenge should look like:
private double mPrecipChance;
Hope it helps and happy coding.

To pass the challenge,
this line:
private int mLowtemp;
..needs to be
private int mLowTemp;

You are correct to pass the challenge and to follow standard naming conventions that change is necessary. Fortunately the error for this mistake is a little more explicit. As you know the code would function properly with a variable named mLowtemp. I believe the real challenge in this case is knowing that double is a different data type.
