893 WWUS44 KFWD 122049 WSWFWD URGENT - WINTER WEATHER MESSAGE National Weather Service Fort Worth TX 249 PM CST Fri Feb 12 2021 ...HISTORIC WINTER STORM POISED TO IMPACT THE REGION SUNDAY AND MONDAY... Impacts will begin as early as Saturday morning with patchy freezing drizzle developing late tonight into Saturday morning, which will lead to a light glaze of ice in some locations. After a brief break in precipitation on Saturday, conditions will begin to deteriorate late Saturday evening, with precipitation transitioning from a sleet and freezing rain mix to all snow by Sunday. The heaviest snow can be expected on Sunday and Monday. High winds will lead to blowing and drifting snow with wind chills falling to below zero by late Sunday. Snow will come to an end during the day Monday, but extremely cold temperatures will persist through mid-week. The heavy snow and forecast long duration of extremely cold temperatures will likely lead to major stress on the region's infrastructure as well as crippling travel for several days.

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 Fort Worth, TX wrote its last area forecast discussion before this winter storm watch went out at Feb 11, 12:50 PM CST, 3 hours 1 minute earlier.

Area Forecast Discussion National Weather Service Fort Worth TX 1250 PM CST Thu Feb 11 2021 ...New Short Term, Aviation... .SHORT TERM... /NEW/ /Through Friday/ Key Messages: (1) Freezing rain mixed with sleet continues across much of North Texas. Additional accumulations of one-tenth to one-quarter inch are likely. A Winter Storm Warning continues through 6:00 p.m. CST this evening. (2) Temperatures across the region will remain below freezing for at least another 24 hours. Any ice already on the roads will remain there through tonight and much of Friday. Roads will continue to be very hazardous. (3) Cold and windy conditions will continue into Friday with Friday morning wind chills expected to be in the upper single digits to lower teens across the region. GOES-E water vapor channel imagery shows a potent upper-level shortwave trough moving over the south-central CONUS and northern Mexico. The axis of this trough is along a line from El Paso to Cabo San Lucas. At the surface, a front remains stalled near the Texas Gulf Coast with a 1014 mb low located off the Louisiana coast south of Lake Charles. Strong isentropic ascent continues above the surface front with a pronounced frontal inversion noted near the 850 mb level (1,300 m AGL). The majority of precipitation occurring across Central Texas is falling as freezing rain, but some of the stronger convective elements are also producing sleet where parcels are able to be lifted into the dendritic growth zone. HREF guidance continues to show the heaviest freezing rain accumulations along a line from Temple to Fairfield where widespread ice accumulations of more than one tenth of an inch are expected. Locally higher amounts in excess of one-quarter inch will be possible, particularly within the heavier convective elements. Freezing rain should end from southwest to northeast, ending across the region this evening. Overnight, temperatures will remain quite cold with the entire forecast area falling into the upper teens to mid 20s. This means any icy conditions that have developed today, will persist through the overnight hours. It is important to stress this point: road conditions will remain quite hazardous through at least Friday morning. The good news is that no additional ice accumulations are expected as drier air will begin to move into the lower levels of the atmosphere. Heading into Friday, cold and breezy conditions will continue. A few peeks of sunshine may be possible in our far northern counties, but most of the area will remain overcast. Godwin && .LONG TERM... /Issued 408 AM CST Thu Feb 11 2021/ /Friday through Next Week/ Main Points: Ongoing cold conditions become dangerously frigid over the weekend and continue into next week, leading to a prolonged period of temperatures remaining below freezing. Widespread snowfall still looks likely late Sunday and Monday, with more chances for snow around the middle of next week. Travel Impacts appear likely for the first half of next week. Weak ascent will develop into Friday morning as the shortwave responsible for ongoing precipitation turns east across south Texas. This may produce more light freezing drizzle and cause more minor impacts on bridges and overpasses. Most areas, however, should remain cold and dry as arctic air remains in place, with highs topping in the 20s and 30s. The upper level pattern is expected to remain active through at least the middle part of next week. The next shortwave will drop southeast across the Desert Southwest and Northern Mexico Friday and Friday night and head for South Texas on Saturday. Most precipitation associated with this feature will remain to our south, but may still bring a few pockets of light sleet with no impacts expected. A much stronger disturbance will cross the Four Corners Saturday night and head for West Texas on Sunday. This shortwave will be embedded in broad cyclonic flow aloft and will be capable of generating widespread precipitation as it moves across the Southern Plains. All key ingredients will be in place (moisture, lift and cold air), and confidence remains fairly high that snow will be the dominant and possibly the only precipitation type. Using a combination of the National Blended Model along with other ensemble mean data creates fairly widespread storm totals of 3 to 6 inches from Sunday through Monday, with the highest totals along the Red River. In reality, some areas could receive significantly more while others significantly less, and it's still too soon pinpoint these details. After coordinating with neighboring offices, the consensus was that 84 hours in advance is too soon for any headlines, so the event will be emphasized in a Special Weather Statement and highlighted with graphics and social media posts with this package. Significant travel impacts would result from such a storm, especially if models begin to trend toward the higher snow totals. The system will continue off to the east, ending precipitation from west to east Monday afternoon and evening. Meanwhile, an upper low which had been anchored over Manitoba will finally shove off to the east as well. This combination will unleash a stronger an colder southward push of arctic air through the Plains, bringing North and Central Texas some of the coldest air it has experienced in 30+ years. Widespread single-digit low temperatures are likely Monday and Tuesday, with exceptionally cold conditions continuing Wednesday. Persistent north winds of 15 to 25 MPH will produce wind chills at or below zero for much of the region for the first half of the week. Yet another upper level system will bring additional snow chances on Wednesday, though too much uncertainty still exists regarding specific totals. Whatever the case, the next week will be full of weather hazards, and folks are urged to make plans to protect themselves and those vulnerable to extreme cold, cover any exposed pipes, ensure your pets are indoors, and any other outdoor animals have adequate shelter. 30 && .AVIATION... /NEW/ /18Z TAFs/ Widespread FZRA mixed with PL continues across Central Texas, with additional ice accumulation likely at KACT. FZRA should end by 00Z. In the D10 TRACON, MVFR CIGs persist, with some slow improvement forecast over the next several hours. CIGs may reach low-end VFR after 07Z as drier air moves in to the lower levels across the region. Clouds may scatter out after 18Z Friday. At KACT, CIGs look to remain IFR through 00Z, and MVFR through the end of the period. Winds will remain from the N at 10-15 KT at all terminals. Godwin && .PRELIMINARY POINT TEMPS/POPS... Dallas-Ft.

Widespread freezing rain can be expected through the rest of today across parts of Central Texas. Accumulations of around one tenth of an inch are expected, with locally higher amounts in excess of one quarter of an inch possible. These ice accumulations will lead to extremely hazardous travel conditions. People are urged to stay home unless travel is absolutely necessary. Temperatures will remain below freezing through the overnight hours, meaning ice will remain even after precipitation has ended. .DAYS TWO THROUGH SEVEN...Friday through Wednesday. Exceptionally cold conditions are likely this weekend through the middle of next week. Wind chill values will fall into the single digits (possibly below zero in some locations) starting Saturday and continuing through at least Tuesday. Snow is expected across most of the region late Sunday through Monday. Some significant accumulations may occur with temperatures falling below 10 degrees and breezy conditions. Significant disruptions to travel will likely result. .SPOTTER INFORMATION STATEMENT... Spotter activation is not expected at this time, but reports of accumulating freezing rain and/or sleet are appreciated.
