.SHORT TERM /THROUGH TONIGHT/... Issued at 239 AM MDT Sat Sep 6 2025
Observations through the early morning hours had clear skies for most of the area, with mostly cloudy skies south of Highway 40. The cloudy skies are forecast to burn off shortly after sunrise with maybe some patchy dense fog developing in the breaks of the cloud cover. Otherwise, most of the area has had temperatures drop into the 40s with the clear skies.
This morning and afternoon are forecast to be fairly benign with high pressure over the area for most of the day. The afternoon hours could see surface low pressure develop along the Front Range, and increase winds to around 15 mph from the south. With clear skies forecast for the day, temperatures are forecast to warm into the 70s, with some 80s possible depending on if smoke generally stays out of the area.
This evening and into the overnight hours, there is low chance for some showers and storms with the lower pressure developing along the Front Range and some mid-level moisture moving through. Currently, the forecast keeps the wind and pressure field fairly uniform, which would limit the amount of convergence zones that could spark storms. There is also some dry air forecast to be present around 850-700mb which could keep anything that forms as virga. Wither way, no hazards or impacts are expected from precipitation at this time. As we get later into the night, the low level southerly flow is forecast to allow low level moisture to advect into the area. With winds forecast to be light or maybe slightly from the east, some dense fog could develop if the moisture advection is strong enough. Or, if cloud cover clears out and allows for good radiational cooling. The favored area is generally along and west of Highway 27. Locales that become cloud/fog covered and/or have decent moisture advection could see temperatures linger in the upper 50s. The rest of the area should see temperatures lower towards the low 50s.

.LONG TERM /SUNDAY THROUGH FRIDAY/... Issued at 1254 PM MDT Fri Sep 5 2025
The long-term will see a pattern that we saw a lot of back in July. A ridge will be set up over the Four Corners and Great Basin region as a low over the Great Lakes slowly pushes off to the east and another low moves over the northwestern CONUS. The ridge and northwesterly flow will dominate the CWA Sunday through Monday night, potentially into Tuesday. The speed of the northwestern low will determine when the northwesterly flow will break apart, but Tuesday is when we can expect to see a change in the weather.
Tuesday, as the northwestern low breaks down the ridge, the low will slow to a crawl over the northern Rockies and potentially Fujiwara if the center of the low splits. This looks to happen Tuesday through the end of the workweek, as what`s left of the high shifts its axis over the central Great Plains. In the lower-levels, this will lead to an 850 mb high pressure system over the mid and southern Mississippi River Valley regions as weak lows eject off the northern Rockies with the Tri-State area sandwiched in between the two. This will allow a southerly LLJ to funnel mid and low-level moisture into the CWA as well as warmer temperatures. Upper 80s and low 90s are expected to return no later than Tuesday and remain through the rest of the week. Low are expected to drop into the mid 50s and 60s throughout the long-term.
Due to the heat, moisture, and weak cold fronts, there will be a nearly daily 20% chance of showers and weak storms across the area. Currently, no guidance is showing a strong cold front moving through the area as the upper-level low remains somewhat stationary. If a stronger low and cold front can eject off the the Northern Rockies, all the ingredients will be in place for severe storms. The NBM does not seem to be reflecting the precipitation potential well in this setup. This means the PoPs shown in the local forecasts on our web page are lower than what forecaster confidence in precipitation is. Overall, forecaster confidence in: daily showers and weak storms forming is 20%; at least one day (Tues- Fri) seeing showers and weak storms is 65%; confidence in severe weather occurring at least one day Tuesday-Friday is 10-15%.

.AVIATION /18Z TAFS THROUGH 18Z SUNDAY/... Issued at 1104 AM MDT Sat Sep 6 2025
VFR conditions are expected to prevail through the rest of the day and through most of the night. KGLD has a 60-70% chance of dropping to IFR in fog between 11-15Z tomorrow morning, and a 40% chance of seeing LIFR visibilities. Guidance is suggesting a stratus ceiling will not form, but if it does form, expect MVFR to IFR ceilings for the same time frame. KMCK looks to remain northwest of the worst fog, but there is a 50% chance visibilities will lower to around 5-8 SM between 10-15Z.
This afternoon, KGLD is forecast to see some random gusts in the 15-20 kts range, hence the TEMPO, otherwise, winds at KMCK and KGLD will generally have winds remaining under 10 kts. Tomorrow, southerly winds will be picking up, expect 20+ kts gusts.
