  • Texas Winter Weather Awareness Day

    WINTER WEATHER AWARENESS DAY IN TEXAS – THURSDAY, NOVEMBER 13TH

    The National Weather Service (NWS) and the State of Texas Governor’s Division of Emergency Management have designated November 13th as Winter Weather Awareness Day in Texas. This is an annual safety campaign designed to promote winter weather awareness and safety.

    Every year, West Texas is affected by winter weather, with at least one winter storm impacting the area in a typical year. Across the United States, 41 people die due to winter weather, and each year, dozens of

    fatalities can be attributed to exposure to cold. Add to that number, vehicle accidents and fatalities, fires due to dangerous use of heaters, and other winter weather fatalities, and you have a significant threat.

    The keys to avoiding serious injury or death during a major winter storm include knowing the safety rules to survive cold weather, knowing how to stay informed of forecasts and warnings for winter storm conditions, and preparing ahead of time to handle difficult travel conditions and other exposure to harsh cold weather conditions.

    In support of Winter Weather Awareness Day, the NWS Office in Lubbock will broadcast a series of winter weather safety messages on NOAA Weather Radio All Hazards during late November and early December.

    • Heavy snow can immobilize a region and paralyze a city – stranding commuters, closing airports, stopping the flow of supplies, and disrupting emergency and medical services. Accumulations of snow can cause roofs to collapse and knock down trees and power lines.

    • Exposure to cold can cause frostbite or hypothermia and become life-threatening. Infants and elderly people are most susceptible. What constitutes extreme cold varies in different parts of the country.

    • Frostbite is damage to body tissue caused by extreme cold. A wind chill of -20° Fahrenheit (F) will
      cause frostbite in just 30 minutes.

    • Heavy accumulations of ice can bring down trees and topple utility poles and communication towers. Ice can disrupt communications and power for days while utility companies repair extensive damage. Even small accumulations of ice can be extremely dangerous to motorists and pedestrians. Bridges and overpasses are particularly dangerous because they freeze before other surfaces.

    • At home, primary concerns are loss of heat, power, and telephone service, and a shortage of supplies if storm conditions continue for more than a day. While traveling, motorists could become stranded, and be susceptible to extreme cold.

    • NOAA Weather Radio is the best means to receive winter weather warnings, and all types of
      critical weather information from the National Weather Service.
      The National Weather Service continuously broadcasts warnings and forecasts that can be received by NOAA Weather Radios, which are sold in many stores. The average range of reception is 40 miles, depending on topography. Citizens should purchase a radio that has a battery back-up and a Specific Area Message Encoder feature, which automatically alerts the listener when a watch or warning is issued for a particular county.

  • Severe Weather for Texas Today

    Looks like potential for a fairly significant episode of severe weather across the entire eastern half of Texas.

    Thunderstorms/showers already ongoing at this hour in north and northwest Texas.  This activity will probably mostly subside soon as the atmosphere gets worked over and cold pools get developed.

    More interesting is later a dryline and warm front will come in to play, and that had potential to generate a pretty widespread significant severe weather episode the second half of the day.

    As typical with cool season setups, instability is a mitigating factor. However, other dynamics in place may overcome limited instability.  Amount of available sunshine, position and movement of the warm front and dryline, and small scale mesoscale storm interactions will be the mitigating factors for tornado potential today.

    I suspect we shall see some tornado reports, although I don’t expect to see any long lived or very strong tornadoes.  Probably quite a few high wind events as well.  I don’t think large hail production will be abundant either, given the expected low top nature of storm cells.

    My overall perception from a chasing standpoint is that this will be a typical cool season grunge chase.  Lots of low level cloudiness and abundant rain to deal with, messing with visibilities and generally making chasing difficult.  Given the distance to target area (initially Abilene, probably adjusted south/southeast as position of the triple point becomes clear), and the grunge potential, I am inclinced to sit this one out.

    I am keeping an eye on it, and if my perception improves in the next few hours I am not beyond hitting the road, but it’s not likely at this point.   Good luck to those that brave it.  Maybe you can pull a rabbit out of the hat.  May the Force be with you!
