Weather Folklore

Photo of a Map Room at Penn State University.     As a National Weather Service SKYWARN storm spotter located in Priceville, Alabama, I like to keep a close eye on the weather, especially when severe weather is in the forecast. For those days, I created this web page, together with the smaller "mini version" and the even smaller "micro version." The intent is to give me an amateur's "map room" for north Alabama.

Right: The "Map Wall" in the Meteorology Dept., University Park Campus, Penn State University.

     However, this is not a map room in the conventional sense, since it is not my intent to make a weather forecast. Instead, the purpose of this page is to answer two questions: (1) Will today be a severe weather day? (2) If so, what, where and when?

     Many of these maps look well to my west. The average cold front can cover 720 miles in a day (the distance to Russell, KS), but a fast-moving cold front can cover that distance in 12 hours. Knowing what the weather will be in the next few days gives me the extra time I need to plan and prepare for potentially severe weather. Be Prepared!

Heat: The Major Weather Killer



Heat is the number one weather-related killer in the United States.

Based on the 10-year average from 2000 to 2009, excessive heat claims an average of 162 lives a year. By contrast, hurricanes killed 117; floods 65; tornadoes, 62; and lightning, 48. The National Weather Service has a web page to help individuals and communities plan for and deal with the dangers of heat.

An upper level chart. Note the location of low pressure areas, troughs and ridges, and whether we are above or below the main flow of the Jet Stream. Horizontal divergence and convergence may influence surface conditions. Convergence is where the upper level winds are coming together; divergence is where the upper level winds are being split. In both cases, atmospheric lift can result, enhancing convective activity.

Mesoscale Storms are weather systems smaller than synoptic-scale systems but larger than storm-scale systems. Horizontal dimensions generally range from around 50 miles to several hundred miles. Squall lines, MCCs, and MCSs are examples of mesoscale weather systems. (Source: NWS Glossary)

When conditions appear favorable for severe storm development, the SPC issues a Mesoscale Discussion (MCD), normally 1 to 3 hours before issuing a weather watch. The MCD describes what is currently happening, what is expected in the next few hours, the meteorological reasoning for the forecast, and when/where SPC plans to issue the watch (if dealing with severe thunderstorm potential).

Emergency Resources

Know your enemy!that is, what are the threats that you and your family will face in your area? Then make a plan, prepare a disaster kit, and be prepared to take appropriate action as directed by your local emergency management agency. If ordered to evacuate, do not delay. Flood waters can rise with great speed. About 60% of all flood deaths are people in vehicles that were swept away by moving water, including children who were passengers. The next flood can always be bigger than floods you have seen before; 100-year floods can occur every year.

     History's lesson is clear: those who are prepared are more likely to survive, and those who are not prepared are the least likely to survive (this includes those who are disabled, overweight or have mobility issues).

    This is an issue of personal responsibility. It's not the government's job to save me or my family. It is my job as a responsible adult to take all steps necessary to protect me and my family in an emergency.

    It is unrealistic to expect that any level of government will be able to step in and save me and my family in the event of a catastrophic emergency. Some storms will be so severe that local governments will be unable to rescue citizens in immediate danger or provide emergency food or water. If I ignore a mandatory evacuation order, I will be on your own until after the storm passes, flood waters have subsided, and roads have been cleared. This could be days, a week, or more, and if I haven't put aside extra food and water, my family and I will be getting very hungry and thirsty.

   In the past, the recommendation has been for three day's supply of food and water. Based on recent weather emergencies, a three day supply is not enough; one week's supply might be enough, but two weeks is better. In some publications, I've seen recommendations of up to a four week supply of food and water (as well as other needed survival equipment and supplies; see below). Severe weather events can damage power supplies, water supplies, and create "islands" of neighborhoods and towns surrounded by impassible storm debris or damaged roads. Whatever supplies exist will quickly be sold out; if you are unprepared, you should expect to go hungry and thirsty ... in the dark. On the other hand, a well-stocked pantry will sustain you long after your neighbors have run out of food.

    If the sheriff comes by and tells you either to leave or to put on a body tag, then you've had fair notice. Likewise, if the National Weather Service says that people who ignore evacuation notices “will face certain death,” then you've had fair notice.

    During Hurricane Ike, I heard an telephone interview on television with a woman on the Texas coast who said that she was trusting in God to protect her. Due to flooding, she was already cut off from evacuation routes, and this was more than 15 hours before landfall. She was told two days before that she was in a danger area. She was told the day before that she was under a mandatory evacuation order. In short, God had sent her at least two clear messages to evacuate, which she ignored. I don't know if she survived; I hope so. Many in her area did not.

     First reported as a tropical wave on Aug. 28, 2008, in its 18-day existence Hurricane Ike took at least 195 lives, directly or indirectly. As of Feb. 4, 2009, 34 people remained missing. Some debris fields had not yet been searched due to lack of funds; the death toll could still rise. A number of deaths were residents who did not leave after the first evacuation notices were issued, and were unable to leave once rising waters cut off evacuation routes. The storm surge was 10-15 feet on Galveston Island, and pushed up to 30 miles inland in Louisiana. Almost every structure on parts of the Bolivar Peninsula was completely razed from their foundations. It spawned 29 tornadoes, and was the fourth costliest hurricane in terms of damage inflicted. The official report is available from the National Hurricane Center's 2008 Atlantic Hurricane Season web page.

    If God sends you a canoe, get in and start paddling.

Notes concerning saving this page.
     On potentially severe weather days, I bring up this web page, and then save it to my hard drive. The purpose is to get copies of that day's graphics on my hard drive.
     I then open that saved page, and copy and paste the contents into a text document (it is easier for me to supplement and edit a text document than a new HTML document).
     I have found that when I re-open a saved web page at a later date, that page will often look for the
current graphic, rather than the saved graphic (a function of the "image source" function in HTML). By immediately copying the saved web page (including saved graphics) into a text document, I am able to ensure that I will be able to review all relevant content, graphics and text, at later dates.



     How far out west do we need to be looking? The average cold front can move at about 30 MPH and can cover 720 miles in a day. By way of an example, the distance from Decatur, AL, to Russell, KS, is 722 mi. But a fast-moving cold front can travel at 60 MPH and can cover 1,440 miles in a day (and 720 miles in just 12 hours). Again by way of example, the distance from Decatur to Salt Lake City is 1,424 miles and to Phoenix is 1,438 miles.
     So as Storm Spotters, we sometimes need to be looking much further west than we might think. If I am looking at my weather pages at 6 AM, I'd need to be looking at the Kansas weather maps in order to see a fast-moving cold front that would arrive at 6 PM and I'd need to be looking at the Arizona and Utah maps in order to see a fast storm that could be here in 24 hours.
     Mileages quoted are “air” miles (e.g, “as the crow flies”), based on a distance calculator located at http://www.infoplease.com/atlas/calculate-distance.html
