147 FXUS65 KBOU 241143 AFDBOU Area Forecast Discussion National Weather Service Denver/Boulder CO 543 AM MDT Tue Mar 24 2026 .KEY MESSAGES... - Record heat expected for tomorrow and Wednesday across much of the forecast area. - Elevated to critical fire weather conditions, mainly on Wednesday. - A cooldown on Friday, then warming back up above normal for the weekend. && .DISCUSSION /Through Monday/... Issued at 1100 PM MDT Mon Mar 23 2026 Another period of record heat is expected tomorrow and Wednesday, with a cool down by Friday. Currently, scattered light snow showers over the high mountains continue to decrease. Little to no accumulations are expected. Upper level ridging will build again over the southwestern United States. The forecast area will have fairly weak northwesterly flow aloft on tomorrow and tomorrow night with zonal flow Wednesday and Wednesday night. This ridging will bring temperatures back up to record levels with highs in the upper 70s to mid 80s over the plains tomorrow, and mid to upper 80s on Wednesday. Again, Denver`s all-time record high temperature for March, 86 degrees, could be broken. Elevated to critical fire weather conditions will also return, especially on Wednesday with afternoon humidities dropping into the 9-14 percent range over the plains. Will refrain from a Red Flag Watch as winds are expected to be pretty weak at that time. On Thursday, weak upper troughing is still expected to push across Colorado. This will bring in a cold front, and upslope winds as well as limited low level moisture. The result will be 10-40% pops, mostly in the mountains Thursday afternoon and night. Thursday`s highs over the plains will get into the 70s before the front makes a difference. The plains may have Stratus in place on Friday with high temperatures in the 50s. For the weekend, upper ridging dominates with dry conditions and temperatures well above normal again. There may be a couple weak disturbance moving through the upper ridge on Monday and Tuesday. This will bring the possibility of limited precipitation. Temperatures look to stay above seasonal normals early next week. && .AVIATION /12Z TAFS through 12Z Wednesday/... Issued at 542 AM MDT Tue Mar 24 2026 VFR conditions will prevail for all terminals through the TAF period. Current S/SW drainage winds will hold through around sunrise before veering to NW flow between 14-18Z Tue, producing ~2 hr window of generally westerly flow at the terminals during the transition. NW flow pattern is expected to hold through the afternoon with speeds 09-13 kts, then returning to drainage late evening. Some uncertainty in the direction of flow during the transition back to drainage flow, but winds speeds should be relative light (at or under 10 kts). && .BOU WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION...66 AVIATION...BRQ
