ALT This graphic shows two side-by-side forecast maps from NWS Rapid City titled "Say It Isn't Snow!" The left map shows the "Percent Chance of 0.1" Snowfall or More," with probabilities between 70% and 96% across northwestern South Dakota and the Black Hills (including 96% at Bison, 81% at Buffalo, and 77% at Lead and Custer; Rapid City is at 47%). A text box and red arrow indicates these shaded areas are most favored for snow to mix with rain tonight and/or Monday. The right map shows the "Percent Chance of 1" Snowfall or More," with lower probabilities peaking around 40% to 56% in parts of northwest South Dakota and the higher terrain of the Black Hills (including 56% at Bison, 48% at Faith, and 43% at Custer). A text box and red arrow indicates these shaded areas have the highest potential for a light, slushy coating on grass and elevated surfaces.
