It is approximately 2.6 mi long and flows through Mahoning Township and Danville. The watershed of the stream has an area of 1.87 sqmi. The stream has two unnamed tributaries. Several businesses were historically located along it, and there was a spring nearby in the early 1900s.

Further on, it enters Danville, where it turns southwest. A short distance downstream, it turns south and reaches its confluence with Sechler Run.

Blizzards Run joins Sechler Run 0.58 mi upstream of its mouth.

Hydrology, geology, and geography
The runoff curve number at various sites on Blizzards Run ranged from 68.6 to 81.6 in 2010. The average runoff curve number between these sites was 74.9. The predicted runoff curve numbers of the stream for 2020 range from 69.5 to 82.0, with an average of 75.3. In 2010, the stormwater lag time ranged from 6.7 to 71.2 minutes, with an average of 27.3 minutes. In 2020, the predicted stormwater lag time ranges from 6.7 to 69.6 minutes, with an average of 26.8 minutes.

Historically, there was a spring close to the corner of Mulberry Street and Pearl Street near Blizzards Run. A 1909 report noted that it had the potential to become polluted. The spring was little-used in the early 1900s. During freshets, the waters of the stream sometimes backed up into the spring. A reservoir is also located on the stream.

History
Blizzards Run is of natural origin.

In the 1800s, Blizzards Run experienced severe pollution. A number of drains connected to it and it served as an open sewer in this period. In the early 1900s, a plant belonging to the Hanover Brewing Company was based in the valley of Blizzards Run. A drain from a slaughterhouse also discharged into the stream during this period. The plant of the Danville Structural Tubing Company was situated at the mouth of the stream in the beginning of the 1900s.

In the early 1900s, Blizzards Run flowed under two railroads.

The Montour County Hazard Mitigation Plan includes erosion control along Blizzards Run to remedy flooding. In 2012, a number of residents of the Gaytowne subdivision filed a lawsuit against Mahoning Township for not following a subdivision plan and thus causing Blizzards Run to flood. The lawsuit was rejected by a Montour Count judge.
