Area Forecast Discussion National Weather Service Pueblo CO 1122 PM MDT Sun May 2 2021 .UPDATE... Issued at 806 PM MDT Sun May 2 2021 Have allowed the Red Flag Warning to expire at 8 pm. Rest of forecast still looks to be on track with beneficial precip overspreading the region tonight through tomorrow. \/Hodanish && .SHORT TERM...(This evening through Monday) Issued at 236 PM MDT Sun May 2 2021 What a day it's been already with strong to severe storms ongoing across parts of the region. This much needed moisture will continue to develop anafrontally, if that's a real word, this evening into the Monday morning hours. A Severe Thunderstorm Watch remains in effect until 7 PM MDT for our eastern plains counties where a brief tornado spin-up is possible, large damaging hail, and damaging winds are all on the table. Somewhat better moisture still exists farther east, dewpoints in the upper-30s to low-40s, so storms will likely continue in current strength all the way to the Kansas boarder. The Red Flag Warning also remains in effect for the San Luis Valley as relative humidity values in the single digits and gusts still pushing 35 to 40 MPH. Heavier mountain snow is expected later this evening into much of Monday as favorable east-northeast upslope flow gets cranking. Still have the Winter Storm Warnings and Winter Weather Advisories in place for Pikes Peak, Central Mountains and the Southwest Mountains. Behind the cold front this evening, temperatures with overcast clouds and rain will keep us well below normal for Monday. .LONG TERM...(Monday night through Sunday) Issued at 236 PM MDT Sun May 2 2021 Shower coverage will wind down late Monday night giving way to some improvement on Tuesday and Wednesday. Still have the potential for enhanced convective activity Tuesday and Wednesday afternoon, mostly across the high terrain. Temperatures begin to moderate back to and above normal by middle part of the work week as mid-level ridging moves in. Expecting mostly dry conditions mid-week through much of the weekend. Next shortwave trough of low pressure may bring some additional moisture to the region late next weekend. && .AVIATION...(For the 06Z TAFS through 06Z Monday night) Issued at 1120 PM MDT Sun May 2 2021 A moist Pacific weather system will bring low cigs and precipitation to the 3 TAF sites during the next 24 hours. Expect mainly MVFR conditions through the period. Precip should be mainly liquid although some snow will be possible at KALS late in the period tomorrow. Winds will be breezy for most of the forecast period at all 3 sites. && .PUB WATCHES/WARNINGS/ADVISORIES... Winter Weather Advisory until midnight MDT Monday night for COZ058-060-066-068-073-075-081.

Isolated to scattered strong to severe thunderstorms may affect locations along and north of a line from Colorado Springs to Lamar between 12 PM MDT and 9 PM this afternoon and evening. The strongest storms will be capable of producing large hail of 1 to 2 inches in diameter, along with 60 to 70 mph wind gusts that could create damage. More isolated strong to severe storms may be possible late this afternoon and evening near the Kansas border, south of Lamar. Areas of north winds gusting to 40 to 55 mph, possibly locally higher, may affect the plains outside of thunderstorm activity this afternoon and evening. These winds may also produce areas of blowing dust reducing visibilities and strong cross winds on east to west oriented highways. The potential for moderate to heavy rain could produce flooding over the burn scars of the southeast Colorado mountains late tonight. Moderate to heavy snow is expected to develop tonight over the mountains, with the heaviest snow expected over the higher elevations of the eastern mountains. .DAYS TWO THROUGH SEVEN...Monday through Saturday The continuation of moderate to heavy rain through Monday morning may result in flooding over the burn scars of the southeast Colorado mountains, before precipitation changes to snow. Moderate to heavy snow is expected to continue over the mountains through Monday night. Snowfall totals could reach 10 to 18 inches for the highest elevations of the Pikes Peak and Wet Mountains areas, and 6 to 14 inches elsewhere across higher elevations of the central and southern Colorado mountains. .SPOTTER INFORMATION STATEMENT... Weather conditions that meet reporting criteria for spotters will be likely this afternoon and evening across the southeast Colorado plains, and overnight across the Mountains. 88/88
