The fun begins at about 7:30am! This radar image is nuts. A lot of the yellow and orange (40 to 45 dbz) returns are due to snow falling into the warm layer. Water-coated snowflakes are highly reflective. This is called “bright banding”… and there is vertical continunity to the 40-45dbz band as you go up in elevation angle. This huge, heavy precipitation area is moving north at about 35 mph, and the leading edge will reach Dumas at around 7:30 or so.
