Area Forecast Discussion National Weather Service Denver/Boulder CO 205 PM MDT Mon Jun 1 2026 .KEY MESSAGES... - A chance for strong and severe thunderstorms this afternoon along the I-25 Corridor, with large hail, gusty winds, and a brief tornado possible. - Severe storms will be possible again Tuesday afternoon, with locally heavy rain possible. - Thunderstorm chances will continue on Wednesday with lower threat for severe storms, however, locally heavy rain will be possible. - Trending warmer and drier by the end of the week. && .DISCUSSION /Through Monday/... Issued at 158 PM MDT Mon Jun 1 2026 The synoptic pattern shows a broad upper-level low is in place over the Pacific Northwest, with a 80kt, southwest to northeast situated upper-level jet residing across the Central Rockies on this Monday morning. This is bringing southwesterly flow aloft across Colorado, with fairly robust low-level moisture (50F dewpoints) advecting into eastern Colorado via southeasterly upslope. Latest East Meso-2 Day Cloud Phase shows cumulus clouds along the Front Range Mountains are starting to show vertical growth early this afternoon. These storms are expected to become more robust within the next hour or two with potential for severe storms to develop along the I-25 Corridor between the 1-2PM time frame, where the SPC has the majority of our lower elevations in a Slight Risk (2/5 threat level). Latest ACARS sounding shows MLCAPE values around 1000 J/kg, with only a few degrees of surface heating needed to overcome a 700 mb inversion. Upslope flow to near 700 mb is also visible on KFTG VAD Wind Profiler, with surface dewpoints ranging from the upper-40s to mid-50s across the foothills and plains. Expecting storms to initially be discrete in nature with large hail (2-3") being the main threat, before progressing eastward where the environment will be more conducive to a more linear storm mode, with strong winds becoming the primary threat. While tornadoes are not expected to be the main threat today, a brief tornado cannot be ruled out where any low-level circulations can hold together. The severe threat is expected to diminish from west to east, moving out of metro Denver by 6PM and 8PM-9PM for the eastern plains. Hi-res guidance has continued to show shower and non-severe thunderstorms becoming reestablished behind the exiting severe threat, mainly along the South Platte River Valley, by 11PM-12AM continuing to around sunrise. For Tuesday, flow aloft will transition to a more zonal pattern with surface dewpoints expected to remain fairly robust once again. MLCAPE values are not expected to be as strong as today, but values between 500 to 1200 J/kg will be in place by the afternoon, with conditions favorable for another day of severe storm potential across the eastern plains. MUCAPE increasing to greater than 1500 J/kg mixed with steep mid-level lapse rates will support the development of baseline severe hail size potential, with shear weaker than today looking to keep the threat of anything larger than 2" limited and gusty outflows the most likely severe threat. Expecting storms to initiate between 1PM to 3PM and coverage to be far less than today, with the SPC having areas generally east of I- 25 in a Marginal risk (1/5 threat level). Afternoon thunderstorms will be possible once again Wednesday, with an isolated threat of some becoming severe, mainly for the eastern plains. Temperatures are forecast to gradually increase through the week, reaching for the 90s by Thursday as 700 mb flow warms by about 10C. Warmer and drier conditions are expected from Thursday onward, with increasing elevated fire weather conditions expected as the warmer and drier weather persists into the weekend, though with greenup well underway and multiple chances for precip through mid-week, any developing fire weather concerns will likely remain limited and localized. && .AVIATION /18Z TAFS through 18Z Tuesday/... Issued at 1158 AM MDT Mon Jun 1 2026 East to southeast winds have increased moisture across the area and brought stratocumulus clouds at 3,500 to 5,000 feet. These clouds will burn off soon as the airmass warms. This increase in moisture will fuel thunderstorm development this afternoon beginning around 19Z. Main time frame for a thunderstorm at DEN will be 20Z to 23Z. Hail (possibly large), heavy rain, and wind gusts to 50 knots will be possible under the stronger storms. Models agree there should only be one round of thunderstorms this afternoon, so by 22-00Z, expect storms to be east of DEN. Low clouds will develop after midnight between 08Z and 10Z and then linger most of Tuesday morning. Ceilings are expected to be in the 1000 to 3000 foot range, with a slight chance (20%) of ceilings under 1,000 feet. A Denver cyclone is expected to help form the low clouds. Then mid morning winds become southeast. This will end the threat of lower ceilings (~1000 feet) and slowly erode the remaining low clouds. Another round of afternoon thunderstorms is expected, beginning around 21Z. There's a chance the airmass is capped, with the best chance for this occurring north of Denver. && .BOU WATCHES/WARNINGS/ADVISORIES... None. && DISCUSSION...9 AVIATION...12
