Poor performance on temperatures

Latest version still gives very inaccurate temperatures at night for my location (Moose Jaw, SK, Canada). Currently 10º Celsius lower than actual temperature (12:30 AM). Other locations temperatures are pretty accurate. The temperatures are always way off on weekends.

I would really like this app if their source of current data was accurate. They need a new source of data for my location
