A significant spring storm will continue across most of northern and northeastern Colorado through early Wednesday afternoon. Snowfall totals are still expected to range from 4-10 inches across most of the I-25 corridor, with as much as 24-30 inches across portions of the northern Front Range mountains and foothills. Travel impacts are likely across the higher elevations, and snowy/slushy roads are possible for the Wednesday AM commute across the Denver metro and I-25 corridor. Heavy snow could lead to tree and power line damage overnight tonight due to the wet, heavy snowfall.
After a burst of moderate to heavy snow early this evening, snowfall rates may briefly diminish this evening, before increasing again tonight into Wednesday morning... before ending Wednesday afternoon.
Snowfall accumulation is difficult to predict this time of year due to the warm ground temperatures and increased sun angle. In general, we expect at least a couple of inches of snow across the I-25 corridor, with up to 8-12 inches possible in the Denver area if the coldest and snowiest solutions pan out. Higher totals are likely across the Front Range mountains and foothills.
