762 FXUS65 KBOU 131110 AFDBOU Area Forecast Discussion National Weather Service Denver/Boulder CO 510 AM MDT Mon Jul 13 2026 .KEY MESSAGES... - Hot weather through the entire week ahead. First Heat Advisory of the season issued for the I-25 Corridor. - Only hints of monsoonal moisture reaching the high country by late in the week or next weekend. - Prolonged hot and dry conditions will bring fire weather concerns, although we`ll likely stay just shy of Red Flag criteria most days. && .DISCUSSION /Through Sunday/... Issued at 239 AM MDT Mon Jul 13 2026 An upper level high will continue from the central US into the central Rockies thru Thu. There will still be just enough mid level moisture, over the higher terrain, for isold to widely sct higher based tstms this aftn. Most of this activity will be along and south of I-70 in the mtns and over South Park. Elsewhere it will remain dry and hot. For Tue thru Thu, any monsoon moisture looks like it will stay over wrn CO into the Great Basin. Thus any tstm activity over the higher terrain looks to be rather isold with dry conditions over the plains. Temperatures will remain hot with 90`s continuing over the plains. By Fri thru next weekend, the center of the upper level high will be over the central Rockies. Overall, it still appears the best fetch of monsoon moisture will generally stay to the west of the area with only a slight chc of tstms over the higher terrain. Temperatures will remain above normal. Eventually, the upper level high may shift a bit further south by the following week which may allow for a better influx of monsoon moisture and increasing tstm chances. && .AVIATION /12Z TAFS through 12Z Tuesday/...
