CEDAR RAPIDS, Iowa (KCRG) - When this time of year rolls around, it’s always important to pay attention to how fast the snow melts and how it’ll eventually impact rivers. The “perfect melt” is one that consists of highs around 40 and lows around 25, allowing for an incremental release of water from the snowpack. The melt ahead will be far from that.
As of this writing, we expect over 60 consecutive hours above freezing, with 40 or more of those above 40 degrees. This promotes rapid snow melt and associated rapid rises on creeks and streams. The risk of ice jams will also be increasing.
