SPM 09-12-2018: Strong Winds Aloft Mix to the Surface Producing Impressive Gusts Over Northwest Colorado

September 12, 2018 by ·

Issue Date: Wednesday, September 12th, 2018
Issue Time: 09:25 AM MDT

Summary:

Beautiful day on Tuesday with a few broken high temperature records. A passing shortwave increased cloud cover over the northeast portion of the state and eastern high terrains in the afternoon hours. Not much rainfall to be had with these storms as drier air moved into the region from the southwest. The highest totals for the day were over the Northeast Plains/Palmer Ridge area. Radar rainfall estimations indicate just under 0.5 inches fell over this area. Over the northwest corner of the state critical fire weather returned. Most surface winds were in the 15-25 mph range, and there were some impressive gusts recorded. A Meeker ASOS recorded a gust of 45 mph and the Douglas Pass ASOS recorded a 53mph gust. Thankfully, no new fires were reported on day 1 of 3 with critical fire conditions.

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 fire burn areas (post 2012), which are updated throughout the season to include new burn areas. The home button in the top left corner resets the map to the original zoom.

SPM 09-11-2018: More Sunshine and Isolated Afternoon Showers

September 11, 2018 by ·

Issue Date: Tuesday, September 11th, 2018
Issue Time: 09:34 AM MDT

Summary:

More sunshine and above average temperatures for Colorado on Monday. With drier air being entrained from the west the last couple of days, storms became more isolated in nature yesterday. Light showers were present in the afternoon hours over the Southeast Mountains and San Juan Mountains with more cloud cover over the Front Range. The highest mountain totals were located over Archuleta County where 0.15 inches of rainfall were estimated by radar. An isolated thunderstorm was able to fire along a line of convergence over eastern plains in Lincoln County. It was nearly stationary, so an Areal Flood Advisory was issued though low-level moisture wasn’t too impressive. Radar indicates just over 0.5 inches of rain fell. This same storm, due to the high-base and large temperature/dew point spread produced strong outflow winds. A gust of 62 mph was recorded at the Limon airport at 5:15 PM. Flooding was not reported on Monday.

SPM 09-10-2018: Sunny and Warm with Isolated Showers and Thunderstorms

September 10, 2018 by ·

Issue Date: Monday, September 10th, 2018
Issue Time: 09:05 AM MDT

Summary:

Lots of sunshine and comfortable temperatures across the state to round out the weekend. With drier air being entrained from the west, low-level moisture was on the decrease. However, there was enough residual moisture for a few scatters showers and thunderstorms over the higher terrains. A passing shortwave also helped enhance coverage (minimal extent) over the higher terrains south of I-70. Storm totals over the higher terrains yesterday were generally under 0.2 inches though areas near the Continental Divide received just over 0.25 inches. The highest CoCoRaHS station on Sunday was in La Plata County and recorded 0.17 inches. There was also small hail reported with these thunderstorms. There was an isolated storm that was able to form over the Northeast Plains. With better moisture to the east, totals were also able to increase. Max 1-hour radar estimates were around 0.5 inches. As anticipated, flooding was not reported on Sunday.

SPM 09-09-2018: Mid-Level Moisture Combined with Passing Disturbance for Scattered Showers/Thunderstorms

September 9, 2018 by ·

Issue Date: Sunday, September 9th, 2018
Issue Time: 9:30 AM MDT

Summary:

A plume of mid-level moisture from the west provided the fuel for an afternoon and evening of scattered showers (and couple thunderstorms) over the High Country. The bulk of the activity occurred over the higher terrain of the Northwest Slope, Northern Mountains, and Grand Valley, and Central Mountains, where moisture coincided best with a passing disturbance. Further south, over the Southwest Slope, San Juan Mountains, and San Luis Valley, conditions remained mostly sunny and dry, with only one or two isolated, gusty showers.

East of the Continental Divide, mainly dry conditions won out during the daylight hours as scattered cumulus clouds bubbled, but resulted in mainly virga and gusty winds. A few showers and thunderstorms moved across the Northeast Plains, Palmer Ridge, and far northern Southeast Plains early this morning as the disturbance worked across the area. Gusty winds and periods of light-to-moderate rainfall were the result.

No flash flooding was reported yesterday. For a look at precipitation estimates in your area, please see the State Precipitation Map below.
