STP 09-27-2015: An Encore Of Warm & Dry

Issue Date: 9/27/2015
Issue Time: 8:32AM

Summary:

Saturday continued a string a near perfect early fall days across Colorado, at least weather-wise. Morning low temperatures in the 40s (and even some 30s) quickly led way to afternoon high temperatures in the 80s for most low-elevation locations. The small exception was across the far-east where persistent low-clouds kept locations in the 70s for a second straight day. High elevation locations saw a substantial drying out during afternoons. For example, near Steamboat Springs, afternoon temperatures were in the mid-70s with dewpoint temperatures only in the 10s. Such low relative humidity values can be a cause for wildfire concern, but without a sustained wind, those concerns were greatly mitigated.

Rainfall/flooding were not reported yesterday.

FTB 09-27-2015: Weather-wise, A Perfect Close To The Weekend

Issue Date: 9/27/2015
Issue Time: 8:30AM

— NO Flood Threat Today

The water vapor image, below, shows only subtle changes in the weather pattern since yesterday. A high-pressure ridge continues to dominate over the Southwest U.S. Mid-level temperatures have not changed much since yesterday, so we expect similar afternoon high temperatures today. With highs in the mid to upper 80s in the lower elevations, this is about 5-10F above normal for late September. The emerging player in Colorado’s weather over the next week is a large disturbance coming ashore in California today. This may send some mid and high level clouds over the western part of our state today. It may also provide some much needed rainfall to the state over the coming days (check out our Flood Threat Outlook tomorrow). However, in the meantime, enjoy an excellent finish to the weekend. Flooding/rainfall is not expected today.

STP 09-26-2015: Hardly A Cloud

Issue Date: 9/26/2015
Issue Time: 8:15AM

Summary:

Another picture perfect fall day was recorded on Friday across Colorado. After a cool start in the 40s, temperatures rebounded nicely with high temperatures in the low-80s over the east and mid-80s across the west (higher elevations were of course much cooler). A stubborn morning low-cloud deck kept the far east cooler with highs there only in the mid-70s. Dry was also the theme of the day with dewpoint temperatures falling into the 20s and 30s over most locations, except a very narrow pocket of 50s in the Southeast Plains.

After a prolifically wet start to summer, conditions have been much drier lately for the state as a whole. It will be interesting to see what El Nino will bring for the state during the fall and winter months. Check out our Flood Threat Outlook on Monday for our 2015-2016 snowpack forecast!

Rainfall/flooding were not reported yesterday.

FTB 09-26-2015: Day Three Of Sunshine For Most

Issue Date: 9/26/2015
Issue Time: 7:55AM

— NO FLOOD THREAT TODAY

The mornings have been getting cooler, but the afternoons have been staying plenty warm for Colorado during the past few days. As the water vapor image shows, below, more of the same will continue for today as our resident high pressure ridge maintains dominance over the Southwest U.S. Warming mid-level temperatures will boost afternoon temperatures by a few degrees compared to yesterday. Some low-clouds may hang around the Nebraska and Kansas borders through early afternoon. However, once again, neither rainfall nor flooding are expected.
