SPM 05-20-2020: Rainfall for the Southeast Plains

Issue Date: Wednesday, May 20th, 2020
Issue Time: 10AM MDT


Winds picked up yesterday as the Low started to move west with gusts between 45 and 60 mph recorded across the state. A 68 mph gust was recorded at 3:10PM at Durango’s airport! It was another hot one with highs on par or slightly above Monday. Alamosa beat its daily record for a 3rd day in a row, but it’s not looking likely that record will be beat again this afternoon. Temperatures will be cooling down quite a bit tomorrow and a few degrees today, so it looks like this record breaking heat wave will (thankfully) come to an end.

A weak northward surge of moisture helped bring showers and thunderstorms back into the forecast for eastern CO. Storms over the mountains produced more wind than wetting rainfall. Totals were highest near the Continental Divide in the Northern Mountains where up to 0.5 inches fell. Some severe storms popped up over the Southeast Plains just after 4PM and hung around through 11PM. The nearly stationary storms (that formed on a line of convergence) produced totals around 2-2.5 inches in Crowley County. The Rocky Ford CO agriculture gage showed 1.02 inches for the 24-hour period, and CoCoRaHs in town had just under 1.5 inches. There may have been some hail contamination with some of the gages, but overall, some very much needed and impressive rainfall! Flooding was not reported with these storms as of the time of this posting, but a Flash Flood Warning was issued at 8:45PM.

The map below shows radar-estimated, rainfall gage-adjusted Quantitative Precipitation Estimates (QPE) across Colorado. The map is updated daily during the operational season (May 1 – Sep 30) by 11AM. The following six layers are currently available: 24-hour, 48-hour and 72-hour total precipitation, as well as maximum 1-hour, 2-hour and 6-hour precipitation over the past 24 hour period (to estimate where flash flooding may have occurred). The 24-hour, 48-hour and 72-hour total precipitation contain bias corrections that are not disaggregated into the hourly estimates, so there will likely be some differences. The accumulation ending time is 7AM of the date shown in the bottom right corner. Also shown optionally are vulnerable fire burn areas (post 2012), which are updated throughout the season to include new, vulnerable burn areas. The home button in the top left corner resets the map to the original zoom.
