In brief: In today’s post we discuss the rumors about a “snow bomb” hitting Houston around Valentine’s Day (you will be shocked to learn the rumors are not true). We also discuss our moderating temperatures this week, and what looks to be a splendid weekend ahead.
Gulf coast “snow bomb”
Matt and I began to receive some messages on Saturday morning about the potential for the greater Houston region to receive another Arctic blast around Valentine’s Day. The questions kept coming on Sunday, along the lines of, “rumors are circulating …” about the threat of a major snowfall in the region. We were scratching our heads because there were no valid indications of such an occurrence.
Nevertheless we did a little digging. It was pretty clear from the outset what precipitated the concerns. A single run of the GFS model, the 06z output on Saturday morning (publicly available about 5 am CT, usually) showed a ridiculous amount of snowfall across the Houston area, like two feet. It would set records. Such an event would be historic. But of course there was no real reason to believe a model output that was forecasting an event two weeks away. That is the “silly season” range of model output, and the US-based GFS model is notoriously bad with these kinds of things. And as one might expect, by the very next run, this snowfall was completely gone. Poof!
This, alone, would not have been enough to spark questions. But then my wife stumbled across this post on Facebook later on Saturday morning. Note that it contains a double dose of dumb because the “author” uses the “Houston, we have a problem” cliche.
This nonsense, therefore, came from a deadly duo in today’s day and age when it comes to weather information. First you need a single model run showing a long-range forecast more than 10 days out. Then you need a social mediarologist to spread the hype. It’s a pretty unstoppable combination. But as a consumer there are a couple of things you can do to combat this. First of all, check to see how far out the forecast is. If it’s 10 days or greater, be super wary. If it’s forecasting an extreme event, be super super wary. And if the post uses the #fblifestyle hashtag, you can have a good laugh because this is not a serious person…
