May 16, 2020 by ·

Issue Date: Saturday, May 16th, 2020
Issue Time: 9:00 AM MDT

Summary:

Scattered showers and thunderstorms rolled across much of Colorado yesterday, with the best coverage along/east of the Continental Divide. Most of the activity was of the garden variety, producing periods of light-to-moderate rainfall and gusty winds. A few strong-to-severe storms mixed in over the Urban Corridor, Palmer Ridge, Northeast Plains, and Southeast Plains, producing hail up to 0.75-1.0 inch in diameter and strong winds. A few rain showers continued after sunrise east of the mountains, bringing light rainfall to portions of the Urban Corridor, Palmer Ridge, Southeast Plains, and Northeast Plains.

Flooding was not reported on Friday. For rainfall estimates in your area, check out our 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 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.

SPM 05-15-2020: Finally Some Rainfall for the Southeast Plains

May 15, 2020 by ·

Issue Date: Friday, May 15th, 2020
Issue Time: 9:50AM MDT

Summary:

Showers and thunderstorms returned to the forecast yesterday over the northern border and eastern plains as there were a slight increase in moisture and lift with the passing trough to our north. As storms initially rolled off the mountain into the plains, a lot of the low-level moisture had mixed out so there was more brief windy conditions and clouds than measurable rainfall. The ALERT system picked up around 0.25 inches for the storm that moved through Coal Creek Canyon. Around 1PM, 0.88 inch hail was reported with a storm that moved through Berthoud. Between yesterday’s morning and afternoon rainfall in Weld County, 24-hour totals tallied around 1 inch. Overnight storms on the Southeast Plains produced the highest 24-hour values, and rainfall was estimated at over an inch. A CoCoRaHS station north of La Junta reported 1.42 inches of rain, which is very much needed in this region due to the worsening drought. Flooding was not reported on Thursday.

SPM 05-14-2020: Overnight Storms for the Fort Collins Area

May 14, 2020 by ·

Issue Date: Thursday, May 14th, 2020
Issue Time: 9:05AM MDT

Summary:

The biggest surprise yesterday were the late night and early morning storms over the Fort Collins/Greeley area. Behind a cold front, moisture had returned to the area. A subtle shortwave moving through the area helped spark the thunderstorms, which also produce small hail. The mesonet in Fort Collins reported up to 0.98 inches over the 24-hour period, although the small hail may have contaminated this reading. Either way, impressive totals. Weak rainfall was also sparked by this same shortwave over the Northern Mountains with totals estimated up to 0.15 inches. Elsewhere, it was a quiet day with dry conditions. Thankfully no new fires were reported, as of this morning, despite extreme fire conditions across southern Colorado.

SPM 05-13-2020: Cooler Temperatures & Drier Conditions

May 13, 2020 by ·

Issue Date: Wednesday, May 13th, 2020
Issue Time: 8:55AM MDT

Summary:

Much quieter weather day on Tuesday with subsidence and drying in the wake of the last system. Temperatures were much cooler across the eastern plains thanks to ongoing cloud cover, and highs did not reach above 40F over the northeast corner. Warmest temperatures were over the Northwest Slope where less cloud cover helped temperatures rebound more quickly. Radar estimates of rainfall indicate that precipitation occurred over southern Rio Blanco County and along the Continental Divide in Fremont County. Totals were between 0.05 and 0.10 inches. Flooding was not reported.
