STP 05-20-2017: Departing Storm Continued To Produce Rain For Eastern Areas

Issue Date: Saturday, May 20th, 2017
Issue Time: 10AM MDT

Summary:

Showers (with a few snowflakes mixed in) continued across mainly the Northeast Plains and northern parts of the Urban Corridor as the disturbance responsible for Thursday’s snowstorm continued to slowly trek out of Colorado. Over 1 inch of light to moderate rainfall was observed in Logan and Yuma counties with many other neighboring regions tallying between 0.25 and 0.75 inches of rain. Across the Continental Divide, residual moisture caused upslope rain and snow showers in the Grand Valley, Central Mountains and Northern Mountains. However, total precipitation remained below 0.25 inches.

A bit of the recent snow was able to melt (or maybe more like compress) on Friday, but this was limited by a persistent low cloud deck especially east of the Continental Divide. As of this morning, many areas in the Front Range still noted a snow depth above 12 inches.

The main riverine flooding concern was on the South Platte River, especially around the confluence with the Cache la Poudre. The flood crest occurred in that area on Friday and levels will continue to slowly recede, though this will be mitigated by melting snow over the next few days. Below is a hydrograph from the Kersey gauge that captures the entirety of the storm event.
