Critical Fire Weather Threats and Dangerous Heat Continue Across the West

Dangerously hot temperatures will continue early this week over the Desert Southwest, with critical fire weather threats from the same region northward into the Great Basin.

Memorial Day became a federal holiday in 1971, so the data is from that year. Below is a listing of the climate records on Memorial Day for Rapid City, Lead, Gillette, Winner, and Lemmon, as well as the weather at the Rapid City Airport for the past 10 Memorial Days. Record high temperatures have broken 90 degrees in some places, and record lows have been around 30. Last Memorial Day was cool and rainy at the Rapid City Airport.

*Data for Rapid City was compiled from the office’s three locations: the original downtown Weather Bureau Office (WBO) data goes from 1888-1942; the office moved to the airport in 1942, and relocated to East Rapid City in 1995. Average highs and lows were calculated based on averaging those of the three different sites.
