Do Not Adjust Your Set ... Part Two!
A look at today's afternoon weather conditions reveals that Altus is cooler and more moist, relative to its Mesonet neighbors: http://ticker.mesonet.org/archive/19990826/current.wx.gif
Is this poor performance by a Mesonet sensor? Actually, no. Altus is in the heart of cotton country, and a quick call to the Extension agent in Jackson County verified that irrigation efforts are in full swing.
Overnight Turbulent "Heating"
The second Ticker item refers to today's Burneyville meteogram: http://ticker.mesonet.org/archive/19990826/BURN.met.gif
Look at the hours between 3:00 and 6:00 am, particularly the temperature, dew point, and wind speed. When the wind stiffened shortly after 3:00 the temperature rose ten degrees! The dew point dropped noticably as well.
This is undoubtedly the turbulent mixing of surface air with the layer(s) above. And, once again, meteograms pack a lot of meteorology into one image.
