What forecasters said that day
The local office's own words before this blizzard 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 blizzard watch went out at Mar 22, 11:31 PM MDT, 4 hours 36 minutes earlier.
Area forecast discussion, Mar 22, 11:31 PM MDT, 4 hours 36 minutes before
Area Forecast Discussion National Weather Service Pueblo CO 1131 PM MDT Wed Mar 22 2017 .UPDATE... Issued at 604 PM MDT Wed Mar 22 2017 Updated to cancel Red Flag Warning that was in effect for today for Huerfano and Las Animas counties. Relative humidities in Huerfano and Las Animas counties has risen above 15 percent and therefore the warning is no longer needed. However, a Red Flag Warning remains in effect for Thursday for the I-25 corridor and all of the southeast Colorado plains. && .SHORT TERM...(This evening through Thursday) Issued at 304 PM MDT Wed Mar 22 2017 ...Snow Returns to the Divide...High Fire Danger Returns to the Plains...Thunderstorms Possible... Weather pattern will be in transition over the next 24 hours. Developing upper low off the coast of California is making slow but steady progress eastward this afternoon. Models accelerate the storm and move it eastward over the Great Basin by 6 am Thursday and into western Colorado by 6 pm. As it does so, snow, fire danger and the potential for a few thunderstorms will ramp up across southern Colorado. For tonight, Red Flag conditions are occurring around the Trinidad area this afternoon. Expect those to continue for a few more hours. So, the Red Flag Warning down there will continue for this evening. As for precipitation, not much going on tonight. There will be a few spotty showers possible along the Continental Divide but little if any snow accumulation is expected with those. Thursday is when things start ramping up. Snow should increase along the Continental Divide during the morning hours, with showers becoming widespread. Widespread showers will then continue through the afternoon and start to spread to the higher elevations of the eastern mountains. The high valleys in between could see a few showers but coverage should be pretty spotty and amounts pretty light. The plains should generally remain dry Thursday. There will be a slight chance of thunderstorms across the area Thursday afternoon. The best chance will be over the mountains, closer to the approaching low. However, the far eastern plains, along the Kansas Border, near the dryline will also see a slight chance of storms late in the day. The Storm Prediction Center has this area in a marginal to slight risk of severe weather if storms can develop. Fire Danger will be high across all of the plains Thursday afternoon. Winds, humidity and fuels will meet criteria on a widespread basis starting late tomorrow morning and continuing into the evening. Gusts to 40 mph, humidities down to at least 10 percent and dry fuels will result in the potential for extreme fire behavior. Burning or any other activity that could accidentally spark a wildfire should be postponed. .LONG TERM...(Thursday night through Wednesday) Issued at 304 PM MDT Wed Mar 22 2017 ...high winds, snow and rain expected through Friday... A very potent storm system is forecast to move across Colorado Thursday night and Friday. The main forecast concerns will be the very strong winds across the Plains, snow over the mountains and into the Palmer Divide, and chance for severe weather out near the Kansas border. Active weather will continue into the middle of next week, however, there are slight differences in the model solutions and ensemble members. Thursday night and Friday...a strong upper level storm system is forecast to move across northern New Mexico and into Western Kansas. Expect snow to move into the Continental Divide Thursday evening and spread into the Eastern Mountains through the overnight hours. A surface dryline is forecast to develop out near the Kansas border late Thursday afternoon. The NAM and NAM 3km develop a line of thunderstorms along the dryline and spread it east into western Kansas during the evening hours. The main question will be how far west convection develops. Modest dewpoints in the 40s ahead of the dryline will lead to CAPE values around 1000 j/kg. Shear looks good which should allow storms to rotate in the mid levels with the primary threat being large hail and strong winds. Again, severe weather will depend on where the dryline sets up. The surface cold front is forecast to quickly drop south over the Palmer Divide and down the I-25 corridor late Thursday night. Northerly winds 35 to 45 with gusts in excess of 65 mph are likely late Thursday night into Friday morning, before spreading east across the Plains Friday afternoon. Hazardous travel conditions are expected on east to west highways. In addition, downed power lines may lead to power outages. Tree damage is also possible. Expect winds to weaken from west to east Friday afternoon and clear into Kansas by the evening hours. The other main concern will be the potential for heavy snowfall over the Palmer Divide. Model guidance suggests 6 to 10 inches with locally higher amounts possible. This snowfall combined with the strong winds will produce very hazardous conditions over northern El Paso County. Near zero visibilities on area roadways and heavy wet snow may cause tree damage on trees where leaves are already occurring. The morning commute on Friday will be heavily impacted. Elsewhere across the Plains, snow levels look to remain above 6000 feet through the event. Lower elevations will likely see mostly rain, with perhaps a few snow flakes mixed in as the upper system moves off to the east. Saturday...a quick moving ridge of high pressure will move across Colorado on Saturday with quiet conditions throughout the days. Temperatures will be 60s for highs. Sunday into Wednesday...another upper storm system is forecast to move across the state Sunday into Monday with another round of rain and snowfall for the Plains. Another storm is forecast to move across the Desert Southwest by mid week which may lead to another period of rain and snow. Mozley && .AVIATION...(For the 06Z TAFS through 06Z Thursday night) Issued at 1125 PM MDT Wed Mar 22 2017 VFR conditions can be expected at the terminal forecast sites tonight through at least late afternoon on Thu. Thu morning, south to southwest winds will increase across all of southern CO, with gusts in the afternoon hours of 30 to 40 kts. KALS could see some showers move into the VCNTY mainly after 21Z, with ceilings lowering, but at this time it looks like they will remain VFR thru the evening.

Southwest winds gusting at 30 to 40 mph are expected to lead to extremely critical fire weather conditions. A dryline is forecast to develop near the Kansas border Thursday evening. One or two strong to severe thunderstorms are possible late Thursday afternoon, into the evening hours. Large hail and strong winds will be the primary threats. Snow will move into the Continental Divide Thursday with several inches of snow possible through Friday morning. Gusty winds will produce areas of blowing snow. A strong cold front will drop south through the plains late Thursday night into Friday morning. Strong northerly winds at 35 to 45 mph, with gusts in excess of 65 mph are likely. These winds will produce hazardous travel conditions on east to west highways, especially for high profile vehicles. In addition, winds may take down power lines and trees, knock out power and cause property damage. Winds are forecast to subside by Friday afternoon from west to east. Snow will move across the Palmer Divide and Teller County late Thursday night into Friday morning. Snow and blowing snow will cause very dangerous travel conditions Friday morning. Snow accumulations of 6 to 10 inches are possible with locally higher amounts expected over the Rampart Range. The very strong winds will also produce poor visibilities, icy and snow covered roads. In addition, the strong winds and heavy wet nature of the snowfall may produce power outages and cause tree damage where spring leafing has occurred. Expect snow to come to an end from west to east Friday afternoon with snow remaining above 6000 feet. Several storm systems are forecast to move across the region over the next week. Another round of rain and snow is forecast for Sunday into Monday, and again Tuesday into Wednesday. There is still uncertainty with storm tracks and intensity at this time. .SPOTTER INFORMATION STATEMENT... Weather spotters will not be needed tonight. 28/28
