What forecasters said that day
The local office's own words before this winter storm watch went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Pueblo, CO wrote its last area forecast discussion before this winter storm watch went out at Jan 19, 10:39 AM MST, 4 hours 37 minutes earlier.
Area forecast discussion, Jan 19, 10:39 AM MST, 4 hours 37 minutes before
Area Forecast Discussion National Weather Service Pueblo CO 1039 AM MST Fri Jan 19 2018 .SHORT TERM...(Today and tonight) Issued at 420 AM MST Fri Jan 19 2018 ...Near Critical Fire Weather Conditions over Parts of the Area today... Upper trough moving onshore across the Pacific Coast will produce increasing southwesterly flow over southern Colorado today and tonight. West to southwest winds will begin to increase in the high country today with gusts to 40 mph possible in the mountains by afternoon, and gusts to around 30 mph along and near eastern mountain slopes. With humidity falling below 15 percent this afternoon, elevated fire danger will develop over the eastern mountains and plains, although the duration of the event looks too short to warrant fire weather highlights. Regardless, there will be some local concerns for brief periods, especially in wind prone areas around Walsenburg and across Fort Carson. It is advisable to postpone outdoor burning or any other activities that could accidentally start a wildfire. Max temps will be very mild for January, reaching levels 20-25f above average and nearing records in many areas. The normal, record and forecast for Colorado Springs tomorrow is 43, 70(1986) and 67. For Pueblo, those numbers are 47, 75(1986) and 71. For Alamosa, those numbers are 34, 56(2000) and 53. Overnight, winds will continue leading to a rather mild night at most locations, and a few spots in the lee of the eastern mountains may stay above freezing the entire night. Precip may reach wrn CO by early morning Sat, but any snow should stay west of the Continental Divide through sunrise and will keep a dry forecast in place. .LONG TERM...(Saturday through Thursday) Issued at 420 AM MST Fri Jan 19 2018 ...Snow and a much colder airmass to spread across the area Saturday night and Sunday... Saturday-Sunday night...Latest models remain in good agreement of a strong upper trough moving across the Great Basin Saturday morning, bringing snow and a much colder airmass to south central and southeast Colorado, as it moves across the area through the late weekend. Moisture increases within the increasing southwest flow aloft across the area ahead of Great Basin system on Saturday, and will see increasing chances of snow along and west of the ContDvd through the late morning, with snow becoming likely through the late afternoon across the Eastern San Juan and La Garita Mountains, where a few inches of wind driven snow could accumulate through the afternoon. Further east, another warm and breezy to windy day looks to be in the offing. Temperatures aloft cool through the day, however, with the downslope flow, will again see temperatures in the 60s to lower 70s across the lower elevations, warmest across the far Southeast Plains. Induced lee troughing across the plains on Saturday will help mix down gusty southwest winds of 20 to 30 mph for areas along and west of the I-25 Corridor through the late morning and afternoon. This will again lead to increased fire danger, however, latest models remain in agreement of increasing moisture within the southerly flow to keep humidity levels at or above 20 percent through the afternoon, and will not issue any fire weather highlights at this time. The broad upper trough continues across the Eastern Great Basin Saturday afternoon and develops a closed low across the Four Corners Region Saturday night. Models then lift this system north and east across the far Southeast Plains through the day Sunday and into North Central Kansas Sunday night. Although the exact track of this system is not certain, the current projected path would continue to bring snow to the ContDvd, especially the Southwest Mountains, through Sunday morning, with the focus of snow across the ContDvd shifting to the Central Mountains through the afternoon with developing northwest flow. With the favored southwest orographic flow, have issued a winter storm watch for Zones 66 and 68 (Eastern San Juan and La Garita Mts) late Saturday afternoon through Sunday afternoon, with a foot or more possible, along expected hazardous travel with blowing snow across the high mountain passes. Snow across the Central Mountains and lower elevations of the Southwest Mountains looks to be in the 4 to 8 inch range, and later shifts will likely need winter weather advisories for Saturday night and Sunday. Snow is expected to spread east across the high mountain valleys through the Eastern Mountains Saturday night, with the current forecasted track of the system supporting a period of wind driven snow, with strong and gusty north winds 20 to 40 mph behind the systems associated cold front, spreading east across the I-25 Corridor through the far southeast plains Sunday morning through Sunday evening. Current grids indicating advisory amount snow fall of 3 to 9 inches across the Eastern Mountains, with 3 to 6 inches of wind driven snow possible across Palmer Divide and Northern El Paso County. Snow fall of 2 to 4 inches will be possible across the Southern I-25 Corridor and Raton Mesa, with 1 to 3 inches possible across the rest of the southeast plains. May also need winter highlights across portions of the plains on Sunday, as snow combined with the gusty north winds, will likely create hazardous travel conditions. Again, a further north or south track to this system could bring less or more snow to the eastern plains. At any rate, temperatures on Sunday will be much colder than Saturday, with highs mainly in the 20s and 30s areawide, warmest across the far Southeast Plains. Monday-Thursday...Moderating northwest flow aloft on Monday becomes more westerly on Tuesday and increasing southwesterly on Wednesday, ahead of another system digging into the Great Basin. This will lead to a generally dry forecast through the period, save possible light snow showers across the Central Mountains, along with a slow warming trend to slightly above seasonal levels by Wednesday. Models do agree on this system bringing another round of snow and colder temperatures to the area for later in the work week, through differ on its strength and location as it moves across the Rockies. && .AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon) Issued at 1028 AM MST Fri Jan 19 2018 A ridge of high pressure continues to build over southern Colorado. Expect gusty westerly winds at KPUB during the early afternoon hours. KCOS is experiencing blocked flow due to Pikes Peak, but the TAFs indicate the westerly winds will prevail early this afternoon. If Pikes Peak continues to block the flow, variable winds will continue. KALS will experience gusting winds late tomorrow morning. All sites will remain VFR throughout the forecast period. && .PUB WATCHES/WARNINGS/ADVISORIES...

Outdoor burning or any other activities that could accidentally start a wildfire today should be postponed. .DAYS TWO THROUGH SEVEN...Saturday through Thursday Near-critical fire weather conditions will be possible across the across portions of the southeastern Colorado Plains on Saturday, as west to southwest winds increase ahead of a strong storm system moving into the Great Basin. This storm system looks to move into the Four Corners Region Saturday night, and then continue across southeastern Colorado through the day Sunday, before lifting into north central Kansas into Sunday night. This system is expected to bring gusty winds and moderate to heavy snowfall to the higher terrain of the Continental Divide late Saturday afternoon through Sunday morning, with hazardous travel expected across the higher mountain passes through the day Sunday. The exact track of this system remains in question, however, the current projected path would support a period of wind driven snow across Eastern Colorado on Sunday, with strong and gusty north winds expected Sunday and Sunday night behind a passing cold front. Light to moderate snow accumulations will be possible across portions of the Eastern Mountains, the Palmer Divide and Raton Mesa, with generally light snow accumulations possible across the rest of the Southeast Plains. Hazardous travel conditions will also be possible across Southeast Colorado on Sunday, with the potential for poor visibilities in snow and blowing snow. Another weak storm system could bring some light accumulating snow to the higher terrain of the Central Mountains Monday and Tuesday. .SPOTTER INFORMATION STATEMENT... Weather spotters will not be needed today or tonight. 10/23
