MESONET TICKER ... MESONET TICKER ... MESONET TICKER ... MESONET TICKER ... June 11, 2010 June 11, 2010 June 11, 2010 June 11, 2010 Heat Burst-amundo! Even the Fonz wouldn't have been cool last night in northwestern Oklahoma when dying thunderstorms produced one of the coolest - errrrrrr ... hottest - hazards around: the heat burst. Yes, I referenced the Fonz. Sit on it! The Ticker has talked about heat bursts many times in the past, but they're still cool to take a look at. And they do have an effect well past their deaths. For instance, take a look at the Mesonet temperatures at 7:05 AM this morning: http://ticker.mesonet.org/archive/20100611/current.TAIR.grad.png Can you tell where the heat burst was? It's pretty obvious a heat burst affected Harper County down through Major County. And if you're out working in the early morning - wheat harvest perhaps - it would give you a chance to start cutting wheat earlier with all that drying that went on overnight. However, a construction job or even soccer practice would not be quite as pleasant. Check out the Mesonet dewpoint temperatures from 7:05 AM: http://ticker.mesonet.org/archive/20100611/current.TDEW.grad.png The heat bursts brought winds of up to 60 mph to Camargo, Freedom and Woodward after midnight: Station Wind Gusts Time Camargo 60 mph 3:05 am Camargo 59 mph 3:10 am Camargo 59 mph 12:10 am Seiling 58 mph 3:30 am Camargo 58 mph 2:50 am Camargo 58 mph 2:35 am Camargo 57 mph 3:35 am Camargo 57 mph 3:25 am Camargo 57 mph 2:40 am Camargo 57 mph 2:25 am Camargo 56 mph 3:20 am Freedom 56 mph 2:45 am Woodward 56 mph 12:10 am Camargo 55 mph 3:45 am Camargo 55 mph 2:55 am Freedom 55 mph 2:50 am Camargo 55 mph 2:20 am The event can be followed in this quicktime movie from WeatherScope showing the Vance AFB radar, the air temperature (colored gradient) and wind speeds (white wind flags). You'll notice the event starts in Harper County and ends up centered over Fairview. This file is a bit large (~10 Mb) so you may want to download it before playing: http://ticker.mesonet.org/archive/20100611/heatbursts.mov It certainly made a difference in the high-low temperature map since midnight. Notice that some of the high temperatures in the northwest are in the 90s already. Those were actually set overnight with the heat bursts. And the low temperature at Fairview only made it to 79 degrees despite the dry air while the mid-70s to the east were due to the moist air in place. http://ticker.mesonet.org/archive/20100611/today.hilo.gif And of course, you can see the event in our stations' meteograms, like this one at Cherokee: http://ticker.mesonet.org/archive/20100611/CHER.met.gif Notice the sharp dewpoint drop and increases in wind speed and temperature. Very cool!
