SPM 05-18-2018: Overnight MCS Rainfall Confined to Nebraska Panhandle

Issue Date: Friday, May 18, 2018
Issue Time: 10:25AM MDT

Summary:

Late day convergence along a boundary helped fuel some isolated thunderstorms over the northern Urban Corridor and Northeast Plains yesterday. These elevated thunderstorms produced stronger winds rather than hefty rainfall. A gust of 40 mph was recorded at the Greeley airport, and 1 inch hail was reported in Peetz. As the storms tracked to the east/northeast, they exited the state by 9PM into the panhandle of NE. Heavy, overnight convection occurred in the panhandle into this morning. A small portion of this convection sneaked its way back into Weld County at the Colorado/Nebraska state line. Radar estimates over the area were 1 inch.

Flooding was not reported Thursday. To see rainfall estimates in your area, scroll down to the State Precipitation Map below.

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 accumulation ending time is 6AM of the date shown in the bottom right corner. Also shown optionally are fire burn areas since 2012. The home button in the top left corner resets the map to the original zoom.

Note: We have identified a possible underestimation in QPE over the southwest part of the state. We are working to on this issue, and will provide an update as soon as possible.
