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:

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:

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.
