I want to know the answer to the following question:
In what month of the year does Richmond's chilliest weather typically end?
All the background I'm provided with is that "The coldest weather normally occurs from late December to early February, and the January daily mean temperature is 37.9 °F (3.3 °C), with an average of 6.0 days with highs at or below the freezing mark.". Is that enough to answer the question?
