Area forecast discussion, Jan 17, 3:14 PM MST, 5 hours 40 minutes before
Area Forecast Discussion National Weather Service Pueblo CO 314 PM MST Sun Jan 17 2021 .SHORT TERM...(This evening through Monday) Issued at 314 PM MST Sun Jan 17 2021 Currently... Thin cirrus with some mid lvl clouds were occurring at 2 pm over parts of the region while just to the north of the fcst area considerably more clouds were noted. Temps over the plains were generally in the U30s over the divides and 40s along the Ark rvr. Interestingly, warmest temps were in the mid Ark Rvr valley where temps were noted around 50F. The San Luis Valley was in the 40s while the mtns were in the 10s and 20s. Skies were dry over the region except over the mainly the higher elevations of Lake County were snow showers were noted per Colorado Mtn College webcam in Leadville. Winds were generally light and diurnally drive, except across the central mtns were breezy winds from the NW were noted per surface obs. Tonight... A weak disturbance will move across the region tonight. This system will be mainly dry for the area, but it will bring some light snow to the central mtns, especially in Lake County. An inches or two of snow is not out of the question. Most of the snow will fall around the midnight hour. Mins tonight will fall into the 20s across the plains with a few low 30s in the normally warmer areas just immediately east of the mtns. San Luis valley will once again fall into the single digits along the river with tens across the rest of the valley floor. Mtns will be in the single digits and 10s. Tomorrow... A stronger weather system will begin to impact the region later in the day on Monday. Snow will once again develop over the central mtns during the morning nd cover most of the contdvd by later in day. the day. By mid afternoon snow showers will become possible along the mtns/plains interface, with some light accumulations possible by rush hour. Nearly all of the remainder of the plains east of the interstate will remain dry. Temperatures tomorrow will be cooler than today with only 30s across the lower Pikes Peak region and U30s and 40s across the remainder of the plains. Upslope winds will develop by mid afternoon but should remain light. With snow developing a bit later than earlier expected, the winter weather highlights were pushed out to 00 UTC (see below) \/Hodanish .LONG TERM...(Monday night through Sunday) Issued at 314 PM MST Sun Jan 17 2021 ...Snow Over and Near the Higher Terrain Monday night and Tuesday... Monday night-Tuesday night...Latest models remain in good agreement with upper level energy digging across the Great Basin through the day Monday, continuing to dig south and west into the Desert Southwest through the day Tuesday. Movement of the this system deepens low to mid level easterly, albeit weak, flow across the region Monday night and Tuesday. This, combined with increasing moisture and generally weak implied lift associated with the passing Great Basin system, will allow for light to moderate snow to develop and persist for areas over and near the higher terrain Monday night into early Tuesday morning, before snow diminishes from northeast to southwest through the day Tuesday. With the expected movement of this system, the best precipitation and snowfall accumulations remain expected across southern and western portions of the area, especially the southern mountains, where NAM and GFS solutions indicate advisory amounts of 5 to 10 inches across the southern Sangre de Cristo and eastern San Juan Ranges through Tuesday afternoon. However, the EC and Canadian solutions continue to indicate the potential higher amounts, especially across the Sangre de Cristo Range. With that said, and the fact latest models have slowed the development of snowfall into late Monday afternoon, have decided to hold on to winter storm watches for the Sangres and San Juans starting at 00Z Tue and continuing to 00Z Wed. As for the rest of the area, may need to add advisories for the Northern Sangre de Cristo and Wet Mountains, as well as the Wet Mountain Valley, the southern I-25 Corridor and the San Luis Valley with 4 to 8 inches possible across the higher terrain and 2 to 4 inches for the valley locales and southern I-25 Corridor through this period. Snowfall of 1 to 3 inches looks possible over and near the Central Mountains, as well as for the northern I-25 Corridor into the Pikes Peak region, with a very tight gradient of snow from west to east, as little or no precipitation is expected east of I-25 into the southeast plains. Below seasonal temperatures are expected on Tuesday, with highs generally in the 30s across the lower elevations, and mainly in the 20s across the higher terrain. Wednesday-Thursday...Latest models continue to indicate differences in model handling of the Desert Southwest system's ejection across the Rockies through the day Thursday, though continue to trend towards a weak upper disturbance moving through the westerly flow across the region bringing a few possible mountain showers, especially along and west of the ContDvd, to the area on Thursday. Otherwise, a dry forecast remains in place, with temperatures warming back to above seasonal levels into the 50s across the plains, and mainly 30s and 40s across the higher terran for both Wednesday and Thursday. Friday-Sunday...Model differences continue into the upcoming weekend, though they do agree on moderate to strong west to southwest flow developing aloft, as more eastern Pacific energy digs into the Great Basin on Friday. The latest GFS continues to slowly translate this system across the Rockies through the day Sunday, where as the EC splits the system with the main piece digging south and west into the Desert Southwest once again. Either way, pattern supports good chances of snow across the ContDvd Saturday and Sunday, with breezy to windy conditions expected across the area, leading to possible critical fire weather conditions across the plains on Saturday. NBM spreads slight pops across the plains late Saturday and Sunday, and have followed suite for now, with cooler temperatures for Sunday. && .AVIATION...(For the 00Z TAFS through 00Z Monday evening) Issued at 314 PM MST Sun Jan 17 2021 VFR conditions are near certain tonight through mid afternoon tomorrow. Some snow showers could occur at KCOS reducing vis and lowering cigs by very late in the afternoon. Over KPUB and KALS VFR is expected through all of tomorrow afternoon. Winds will be light through the period. && .PUB WATCHES/WARNINGS/ADVISORIES... Winter Storm Watch from Monday afternoon through Tuesday afternoon for COZ068.

The heaviest snow will likely occur over the east slopes of the southern Sangre de Cristo Range and Wet Mountains Monday night, before shifting into the San Juan Mountains early Tuesday morning. Lower elevations along and west of I-25 will see mainly light snow, and the far eastern plains may only see some spotty snow showers and flurries Monday night and early Tuesday morning. Although snowfall amounts are still subject to change, snowfall amounts of 6 to 12 inches will be possible across the southern Sangre De Cristo and eastern San Juan mountains, with 3 to 8 inches possible across the remainder of the southern mountains south of highway 50. One to 4 inches will be possible across the remainder of the mountains to the north of highway 50, with up to 2 inches possible across the valleys and adjacent lower elevations of the southern I-25 corridor.
