808 WWUS45 KBOU 112124 WSWBOU URGENT - WINTER WEATHER MESSAGE National Weather Service Denver CO 324 PM MDT Mon Mar 11 2019 ...Blizzard expected to develop over portions of northeast Colorado Wednesday afternoon and Wednesday night... .Heavy snow and very strong winds will develop over most of northeast Colorado Wednesday afternoon and Wednesday night. The most severe conditions are likely to develop just east of the I-25 Corridor where the heaviest snow is expected to fall. Power outages and wind damage will also be possible as winds gust to between 60 and 70 mph. Further west along the I-25 Urban Corridor, heavy snow and gusty winds will also be possible, with significant travel impacts. Rain is expected to develop Tuesday night, and then change to snow Wednesday morning and may become heavy at times. Mountain areas will also see more accumulating snowfall during this period. A powerful storm system will move into southeast Colorado or southwest Kansas by Wednesday morning, and then track slowly northeast into southwest Nebraska by Wednesday night. Meanwhile surface low pressure will intensify rapidly over southeast Colorado, producing the very strong winds and heavy snowfall.

Scattered showers and a few embedded thunderstorms have been moving over northeastern Colorado this evening and snow shower activity has been on the increase over the mountains. By Wednesday morning, a rapidly deepening low pressure area is forecast to be located over southeast Colorado. Rain is expected to be falling across the northeast plains by sunrise. A cold front will move over the northeast plains between 8 AM and noon, changing precipitation over to snow and drastically increasing the winds as cold air moves in from the north. Blizzard conditions are expected to spread across northeast Colorado through the afternoon as snow intensities increase and strong winds produce poor visibilities in blowing and drifting snow. The most hazardous conditions will be from the I-25 corridor eastward. Blizzard conditions are expected to persist overnight. West of the I-25 Urban Corridor, winds will be a little less than out on the plains, but moderate to heavy snow will combine with the winds to produce significant travel impacts during the afternoon and evening. Mountain areas will also see more accumulating snowfall overnight and Wednesday.

273 WWUS45 KBOU 131031 WSWBOU URGENT - WINTER WEATHER MESSAGE National Weather Service Denver CO 431 AM MDT Wed Mar 13 2019 ...INTENSE WINTER STORM DEVELOPING FOR THE MOUNTAINS AND EASTERN COLORADO... .A winter storm centered over southeastern Colorado will rapidly intensify this morning. This will produce very strong winds and areas of heavy snow. Rain will change to snow along the Front Range this morning, with blizzard conditions developing quickly in the late morning or early afternoon. These conditions will spread eastward across the plains this afternoon. Near zero visibilities are expected with wind gusts of up to 80 mph and up to a foot of snow on the plains east of a line from Greeley to Denver International Airport. In areas closer to the mountains, there will be less snow, but a period of very heavy snow and strong winds is likely during the day today that will likely create near blizzard conditions for a while. Strong winds will continue to create blizzard conditions on the plains overnight tonight. Closer to the mountains, there will be some improvement but still enough wind for some drifting snow and continued difficult travel. Much of the northern Colorado mountains will also see heavy snow and windy conditions today, especially near the Wyoming border. Travelers across the Colorado mountains and eastern plains should consider canceling travel plans today, as conditions will deteriorate quickly during the late morning or early afternoon. Be aware that if you go somewhere this morning, you could become stranded or have a very difficult time returning this afternoon. Road closures can be expected, especially on the eastern plains and near the Wyoming border, but possibly also along the I-25 corridor during the peak of the storm later today. Residents should also be prepared for power outages from the very strong winds.

This will produce very strong winds and areas of heavy snow. Rain has already changed to snow over the I-25 urban corridor, and rain will change to snow over the plains during early to middle afternoon. Blizzard conditions will develop quickly through the early afternoon. Near zero visibilities are expected with wind gusts of up to 80 mph and up to a foot of snow on the plains east of a line from Greeley to Denver International Airport. In areas closer to the mountains, there will be less snow, but a period of very heavy snow and strong winds is likely during the day today that will likely create near blizzard conditions for a while. Strong winds will continue to create blizzard conditions on the plains overnight tonight. Closer to the mountains, there will be some improvement but still enough wind for some drifting snow and continued difficult travel. Much of the northern Colorado mountains will also see heavy snow and windy conditions today, especially near the Wyoming border. Travelers across the Colorado mountains and eastern plains should consider canceling travel plans today, as conditions will deteriorate quickly during the late morning or early afternoon. Be aware that if you travel today, you could become stranded or have a very difficult time returning this afternoon. Road closures can be expected, especially on the eastern plains and near the Wyoming border, but possibly also along the I- 25 corridor during the peak of the storm later today. Residents should also be prepared for power outages from the very strong winds.

947 WWUS45 KBOU 132259 WSWBOU URGENT - WINTER WEATHER MESSAGE National Weather Service Denver CO 459 PM MDT Wed Mar 13 2019 ...INTENSE WINTER STORM CONTINUES EAST OF THE MOUNTAINS... .The powerful winter storm affecting eastern Colorado today has spread blizzard conditions across northeast Colorado from the Front Range Foothills eastward to the Kansas border and from the Wyoming border down to the Palmer Divide. Winds have been gusting to 65 mph at most locations and up to 80 mph at a few locations. The winds and snow have decreased in the mountains, so blizzard warnings have been downgraded to advisories for the night for continued light snow. The most intense portion of the storm has now shifted east of the Interstate 25 corridor. Travel across northeast Colorado has been severely impacted with many highways across northeast Colorado closed. Highway closures include I-76 northeast of Thornton, I-70 east of Watkins and I- 25 from the Denver Tech Center to the Air Force Academy. I- 70 west of Denver has also been closed from Golden to Idaho Springs. Pena Boulevard to Denver Airport has also been closed. Power outages have also been scattered across northeast Colorado with up to 128,000 customers without power. The blizzard conditions are expected to continue through the evening hours across lower elevations. Some improvement is expected this evening as snowfall rates decrease and wind speeds begin to decrease.

What forecasters said that day
The local office's own words before this blizzard warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Denver/Boulder, CO wrote its last area forecast discussion before this blizzard warning went out at Mar 11, 3:08 PM MDT, 16 minutes earlier.
Area forecast discussion, Mar 11, 3:08 PM MDT, 16 minutes before
Area Forecast Discussion National Weather Service Denver/Boulder CO 308 PM MDT Mon Mar 11 2019 .SHORT TERM...(This evening through Tuesday) Issued at 303 PM MDT Mon Mar 11 2019 Upper level low moving across northern Mexico will bring a southwest flow aloft tonight. Flow backs to the south Tuesday as the low nears Colorado. Satellite and radar showing showers moving northeast across western Colorado at this time. Airmass remains unstable over the mountains through early evening. Snowfall amounts of up to 3 inches will be possible through early evening. A few showers may move across the Urban Corridor and near by plains. Here, rainfall is expected to be light. Eastern Colorado will see the "warm before the storm" Tuesday with highs climbing into the lower 60s. The southerly flow will transport moisture into the area with dew points in the upper 30s to lower 40s. CAPE reaches 500 J/kg across the plains with 1000 J/kg over Lincoln county. Will have a mention for thunderstorms in the forecast for Tuesday afternoon. .LONG TERM...(Tuesday night through Monday) Issued at 303 PM MDT Mon Mar 11 2019 For Tuesday night into Wednesday a closed low will push out of the subtropical pacific and move northeastward into the Intermountain West. Tuesday night into Wednesday the trough over the Pacific NW will push South and merge with the deepening cyclone developing over the Colorado high plains to strengthen potential for moderate to heavy snow over Colorado Wednesday. Current model guidance is narrowing in on a strong deepening of surface low pressure associated with a surface low starting out over the colorado southern plains and tracking into western Kansas through the day Wednesday. This surface low is projected to drop almost 22 mb in 24 hours, just 2 mb shy of a textbook Bombogenesis. Snow will start in the southern mountains first and expand northeastward through the morning hours. Wrap around from the surface low south of Denver will pull in colder air and increase snow for the northern mountains and plains around midnight Wednesday. Winds from the North during the morning hours will help to keep areas south of the Cheyenne ridge slightly sheltered with downsloping but will not be long lived. Warmer surface flow will be over the southern plains with precipitation starting out as rain during the morning hours. The strengthening surface low will help to pull much colder air down from the NW by Wednesday afternoon. This could create a TROWAL affect with colder air undercutting the warm airmass south of I-70 around noon before the colder air extends across the region into the late afternoon hours with -11 to -13 C at 700mb. This will change the rain over to snow by the afternoon and continue into the morning hours on Thursday. A strong low level jet will bring prolonged high winds to the plains with sustained speeds of 45 to 50 mph with gusts upwards of 70 mph Wednesday afternoon and evening. This combined with snow associated with the def zone will bring moderate to heavy blowing and drifting snow to the plains along and east of I-25 to the Kansas border. With the rain ahead of the snow and having a lower liquid to snow ratio, snow density will be higher and snow will be heavier. This could create issues with power over the eastern plains along with dangerous travel conditions Wednesday. Confidence has increased over the last 24 hours with models coming into alignment as the surface low trends slightly westward. This combined with consistency in guidance aided in the decision to issue various highlights. A Winter Storm Watch continues for the northern foothills and mountains with the inclusion of the southern foothills for the morning hours Wednesday into Thursday. We have upgraded the winter storm watch for blizzard conditions to a blizzard warning for areas east of I-25 that will start around noon Wednesday and continue into Thursday morning. For southern Lincoln county, a high wind warning was issued for projected wind gusts up to 70 mph Wednesday afternoon and into the evening hours. The watch was expanded across the mountains and southern foothills. At this time amounts continue to fluctuate with the timing of the changeover from rain to snow and where the surface low sets up on the plains. Various models currently have over 1 inch of water in 12 hours over Denver and east with the possibility of 4 to 8 inches of snow west of I-25 and 6 to 10 inches for areas along I-25 with the possibility of over a foot over the eastern plains by early Thursday. && .AVIATION...(For the 00Z TAFS through 00Z Tuesday evening) Issued at 303 PM MDT Mon Mar 11 2019 Ceilings may fall to 3000 to 6000 feet under the passing showers through early evening, otherwise ceilings are expected to stay above 6000 feet through Tuesday. Light winds will prevail through Tuesday. Forecasting wind direction may be challenging at times due to a circulation over Denver. Strong winter storm is expected to the hit the Denver area. Rain is expected to change to snow 15Z-17Z Wednesday. Heavy snow, strong winds, and blowing snow are expected at KDEN and the Denver area after 18Z Wednesday. An extended period of visibilities less than a quarter mile are expected Wednesday afternoon and early evening. && .BOU WATCHES/WARNINGS/ADVISORIES...
