Last Evening's Cold Front Wears a Coat of Many Colors
Yesterday evening, a run-of-the-mill cold front began its slide across the state, bringing northerly winds and cooler temperatures to Oklahoma today. And, while the front has made some impact on today's afternoon temperatures ( http://ticker.mesonet.org/archive/20000309/delta.tair24.gif ), the real story is how it introduced itself in so many different ways.
As the Ticker has evangelized so many times before, there's a great deal of meteorology packed into a meteogram, so that's what we'll use to look at five different locations in and around central Oklahoma.
At Norman ( http://ticker.mesonet.org/archive/20000309/NORM.gif ), the front just blasted its way in with a stiff wind gust and abrupt change of wind direction.
At Bowlegs ( http://ticker.mesonet.org/archive/20000309/BOWL.gif ) and Bixby ( http://ticker.mesonet.org/archive/20000309/BIXB.gif ), the front eased its way through, accompanied by calming winds and a more gradual change of direction.
At El Reno (http://ticker.mesonet.org/archive/20000309/ELRE.gif ), the wind shift was abrupt and gusty, but the front almost seemed to apologize for itself with a significant (albeit temporary) warm-up in its wake.
At Stillwater (http://ticker.mesonet.org/archive/20000309/STIL.gif ), the front had no immediate effect on the temperature field, but a series of three or four oscillations in the wind field followed its passage.
At Spencer ( http://ticker.mesonet.org/archive/20000309/SPEN.gif ), these oscillations were even more apparent, especially in the wind speed category.
Overall, it was a well-rounded performance by our visitor from the north.
