KEY MESSAGES

- Very hot with scattered, windy showers/thunderstorms through Tuesday. Heat Advisory remains in place over Pueblo/El Paso Fremont Counties for Monday.

- Relief from the very hot temperatures and increased rainfall chances begin Wednesday, with widespread showers and thunderstorms into next weekend.

- Concern for heavy rainfall and flash flooding will increase from late week into the weekend, especially over recent burn scars.

SHORT TERM /THROUGH TUESDAY/

Issued at 129 PM MDT Sun Aug 9 2026

Currently, very hot again this afternoon, with temps already approaching record levels at a few stations as of 1 pm. Isolated high based convection also making a repeat appearance across the area, with wind gusts of over 60 mph with very weak showers already noted along I-25 north of Walsenburg. Remainder of the afternoon will stay hot with random, windy showers and brief thunderstorms, potentially persisting into the evening. Again, not much if any rain with convection, and even lightning will be limited to one or two strikes, as storms will tend to dissipate with 10-15 minutes after formation.

For Monday and Tuesday, center of the upper high drifts eastward through NM, with weak w/sw flow aloft bringing a slow but steady increase in mid-level moisture to southern Colorado both days. Expect a continued ramp-up of mainly mountain convection as a result, and a few higher mountain locations may see wetting rainfall (QPF greater than 0.1 inches) as moist layer deepens. Lower elevations/valleys may see better storm coverage (weak front on the plains Tue may help), but still more wind than rain with most activity. Unfortunately, mid level temps stay warm, with only a degf or two of cooling by Tue afternoon. Will keep heat advisory in place for the Pueblo/El Paso/ern Fremont Counties Mon, and may need one for Tue as well as temps stay elevated. On the plains, maxes both days forecast to drop just slightly below the 105f threshold for an advisory, so will hold off on a heat highlight here for now.

LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/

Issued at 129 PM MDT Sun Aug 9 2026

Upper high center finally shifts into the srn Plains on Wed, then moves even farther east starting Thursday, ending up somewhere over the sern U.S. by the weekend. Resulting upper pattern continues to look favorable for an influx of moisture and widespread showers and thunderstorms starting Wed and persisting into the weekend across the entire region. Rainfall could be enhanced at times by weak upper level disturbances lifting over the wrn periphery of the ridge, with at least a couple weak cold fronts and associated ely upslope surges providing increased low level moisture over the ern mountains and plains. Heavy rainfall and flash flooding from slow-moivng storms continues to look like a threat from Wed onward, especially over recent burn scars, and even unburned locations and urban areas may see increased potential for flooding with repeated rounds of heavy rainfall. As the high moves away, mid level temps cool, and with added help from clouds and precip, max temps may actually end up a little lower than seasonal averages for a change, especially Fri/Sat.

AVIATION /00Z TAFS THROUGH 00Z TUESDAY/

Issued at 459 PM MDT Sun Aug 9 2026

Winds will be dominated by gusty outflow winds from decaying showers through this evening, with the possibility of rogue gusts up to 50kts possible. These will be highly localized and will maintain a prob30 for -SHRA and gusts to 40 kts for KCOS and KPUB through 01z. They could last longer, but confidence is low. Otherwise, breezy winds at all three terminals will decrease through the evening and settle into light diurnal wind patterns overnight. A similar trend can be expected for Monday, though there will be a slight uptick in thunderstorm coverage in the afternoon, especially out west. Will carry a prob30 or tempo group for -TSRA at KALS and -SHRA at KCOS and KPUB after 20-21z. Gusty erratic outflow winds up to 40 kts will be more likely than measurable rainfall at any of the terminals. -KT
