Gaining new knowledge on familiar subjects is something I really enjoy. Born and raised in Oklahoma, I’ve been around severe weather throughout my life. But this year I gained new knowledge regarding weather. A lot of it has come from knowledgable, patient individuals at the National Weather Service and the Oklahoma Climatological Survey. Take for example the EF-4 tornado that hit Lone Grove and the Majestic Hills area near Ardmore on Feb. 10. Mike Foster, meteorologist in charge with the National Weather Service’s Norman Forecast Office, and Rick Smith, warning coordination meteorologist with the National Weather Service, noticed the roofs were missing on four houses in Lone Grove. That’s not unusual with such a strong tornado. However, Foster and Smith walked several hundred yards away from the houses and found no pieces of the roofs. But Foster received a call from a resident at Sulphur who said debris from roofs had fallen there. What I learned from Foster was this: "It gets lofted up to very high levels and then it gets continuously sort of centrifuged out and thrown out off of the left side of the storm. When it gets up into the mid-parts of the storm it’s getting into winds that are far faster than what the speed of the storm is.” Again, I knew that there would be debris nearby and I knew that things such as letters and documents get picked up and carried long distances. But I had never thought about debris being tossed off the left side of the storm. To me, that’s interesting. In May I was blogging from the Norman Forecast Office as a storm was approaching Gracemont and seemingly headed southeast. Four months earlier, I listened as Smith talked with storm spotters about positioning and storms that can be "right movers.” When that storm reached Gracemont that night in May, it went right, which sent it south. An EF-2 tornado hit Anadarko. The last example I’ll give of learning more about weather is that of a winter-type storm that hit in early spring. I had heard National Weather meteorologists as well as Gary McManus, associate state climatologist with the Oklahoma Climatological Survey, talk about a key to snowfall accumulation is where the moisture and cold air meet. Areas in northwestern Oklahoma experienced very heavy snowfall in a late March storm. Reports included 26 inches of snow at Woodward and at Freedom. Those two totals share the record for 24-hour snowfall totals in Oklahoma, McManus said. Some areas to the east, received a few inches, a trace or in some cases, no snow.
