Snow began falling in the Grand Valley on February 1st, 1903. For the next six days, snow fell each day, with 10 to 12 inches total reported across the valley. As a result of a very cold air mass that had moved into the area, temperatures began to fall after the 2nd. With nearly a foot of snow on the ground, temperatures dropped even more due to the air’s contact with the snow-covered surface.

An additional 5.4 inches of snow fell during the latter part of the 2nd week, 5.1" of that falling in a single day. By the month’s end, 14 inches were reported at the Weather Bureau* office (with more in other areas in the valley). Overall, residents in 1903 saw Grand Junction’s 6th snowiest February.

The combination of cold air and snow on the ground kept Grand Junction under frigid conditions for most of that month. With the exception of one day, daytime high temperatures between the 3rd and the 19th remained below freezing (the exception saw a high of only 33°).

Fourteen of the first twenty-one days had morning lows with below-zero values, a February record for subzero temperatures. Nine of the subzero days occurred from the 13th to the 21st, the longest consecutive string in a Grand Junction February. The coldest morning temperature that month was -15°, recorded on both the 7th and the 14th. 

Twelve days from that February still hold daily low temperature records, with ten of them occuring in a row (February 13th through the 22nd). To this day, February 1903 retains the title of Grand Junction’s coldest February.
