I documented a couple of undular bores on my blog here and here. But today, it's personal. The wave-cloud phenomenon struck Wichita, Kansas, this morning, home of AccuWeather Enterprise Solutions, where I got a webcam installed last year. Notice in the time-lapse video below how the wave clouds form "out of nothing" and note at the end several dark shadows as the wave clouds move over the sun for several minutes (the sun is behind the camera).
In the radar animation, you can see the waves propagate across the city via the reflectivity, velocity, spectrum width and even NROT radar types. Often, undular bores show up well on visible satellite, but that wasn't the case this morning (see end of loop).
Over 200 stations may have broken daily low temperature records this morning, with a handful of monthly records. I take a look at North Carolina and Pennsylvania.
The record lows tonight will also affect the Southeast, pushing in cold air not felt since I was in college 20 years ago!
A number of interesting weather and astronomical phenomena were caught on film last night on the AccuCam Webcam Network.
Pennsylvania set a number of cold weather records Sunday and today, and more is on the way.
Folks I can't stress enough how dangerous the weather will be this Valentine's Day Weekend, with Blizzard conditions, RealFeel temps below -40 and snow squalls.
Part of the Rodanthe Pier collapsed into the ocean Thursday as an arctic front passed through and homes in Oak Island remain damaged from an earlier storm.
