There is still a great deal of uncertainty among forecasters and computer models as to the exact impact the approaching winter weather event is going to have, but it does appear that virtually all of Oklahoma will in fact be affected. We continue to participate in planning meetings and discussions, conference calls and briefings, and although there are a variety of opinions and observations, the information below appears to be the best representation, at least at this point. Again, please remember that winter weather is difficult to forecast and a variance in storm system or individual storm attribute movement of even just a few miles can significantly change what is actually experienced in any given area.
I have attached three graphic products from the National Weather Service, one depicting anticipated conditions on Wednesday, one for Thursday and a third with current precipitation predictions for the main impact of the event. Additional information from the latest Sperry-Piltz Ice Accumulation Index posting (SPIA Index, an additional tool typically used by electric utilities and other applications to evaluate ice conditions and the resulting impact) indicates that our area may experience significant power outages including main feeder lines and broken tree limbs, etc. Some of these outages, should they occur, may last for several days. Freezing temperatures and strong winds are expected to continue into the weekend, with Sunday potentially being the first day above freezing (barely).
In addition to constant monitoring of weather forecasts and actual conditions, planning should include the consideration of:
1) potential power outages, including what critical aspects of your home or business will be affected (heat, water supply, medical-related power, etc.)
2) cancellation of travel plans, both incoming and outgoing. Should the event occur as currently predicted, all travel will be strongly discouraged.
3) plan for and make accommodations for the elderly, very young, pets and those who need other forms of assistance. Do not wait until adverse weather happens!
Additional meetings, briefings and conference calls are scheduled to continue throughout the upcoming event and I will keep you advised as conditions change or additional information is made available. For now, here is the latest from the National Weather Service-
Dry and mild weather will continue through Wednesday, before a strong cold front and storm system approach. This storm will produce a mixture of heavy rain, ice, sleet, and snow over Oklahoma and western north Texas. Most of the precipitation will occur Thursday, which will be windy and much colder. Snow is expected in northern Oklahoma. Central and southern Oklahoma are expecting freezing rain and sleet before the snow. Precipitation will end Friday morning and the cold air will persist into Saturday. A warming trend begins Sunday.
