SPM 09-15-2018: Late-Summer Heat Continued

Issue Date: Saturday, September 15th, 2018
Issue Time: 9:30 AM MDT

Summary:

The State Precipitation Map is blank again thanks to another day of hot and dry conditions statewide. The upper-level ridge responsible for it all hasn’t budged much over the last few days, but thankfully winds relaxed a bit yesterday and reduced the areal extent of Red Flag Warnings. The Silver Creek Fire continues to burn in portions of western Grand County and eastern Routt County, with containment at last update around 53%. Looking ahead to today, another day of hot and dry conditions is expected across Colorado, so please use extra caution with any outdoor activities that may produce a spark.

No flash flooding was reported yesterday. For a look at precipitation estimates in your area, please see 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 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 09-14-2018: Day 3 of Critical Fire Weather for Western and North-Central Colorado

Issue Date: Friday, September 14th, 2018
Issue Time: 09:15 AM MDT

Summary:

Above average temperatures once again on Thursday with highs reaching the upper 90Fs over eastern Colorado. Lamar’s high was able to reach 100F! Over western Colorado, highs were in the upper-80Fs to low 90Fs with mountains locations above 70F. To keep this in perspective, these temperatures are 10-15F above average for this time of year. Large Red Flag Warning for western and north-central Colorado yesterday with the upper-level jet sagging southward. Thankfully, no new fires were started and progress continued on the Seaman Fire. It helps that the fire is burning within the 2012 Hewlett Fire burn scar. The flared up Silver Creek Fire continued its expansion and promoted pre-evacuation notices to communities NE of the fire. Unfortunately, enhanced and critical fire weather will continue to promote fire growth over the northwest corner of the state again today. Quite a different weather story when compared to 5 years ago (2013 floods). Please continue to use caution with any activity that could produce a spark.

With dry conditions the last two days, not too much to see on the State Precipitation Map below.

SPM 09-13-2018: Critical Fire Weather for Western and North-Central CO with more Impressive Gusts at Douglas Pass ASOS

Issue Date: Thursday, September 13th, 2018
Issue Time: 09:00 AM MDT

Summary:

Another beautiful and hot day yesterday with temperatures feeling more like mid-summer values than almost-fall temperatures. Enough dry air moved into the state from the desert southwest that only a few clouds were present across the state. High winds mixed down to the surface over the northwest corner of the state and the north-central mountains. Paired with low relative humidity values, a Red Flag Warning was in place. The Douglas Pass ASOS recorded a gust of 67 mph on Wednesday with another ASOS station in Moffat Country recording at 45 mph gust. During the afternoon, a fire was reported in Larimer County near Poudre Park – Seaman Fire. Currently the fire is active with 100-200 acres having already burned. A small grass fire in northeastern Colorado near the Pony Express State Wildlife area was also reported. Thankfully, this fire was quickly put out this morning and burned less than 10 acres. Still not out of the woods yet as critical and enhanced fire weather is anticipated be in-place through the start of next week. As expected, no rainfall on Wednesday except for a few sprinkles over Baca County estimated by radar.

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

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.
