Perhaps this should go in Pseudoscience but since Dutch made his name with youtube vids I'll place it here for now:
He claims that a "frequency pulse" on 25 November caused snow that NWS did not predict on 27 November. He said that the forecast was for clear weather.
His prediction was:
Two days ago — November 25, 2012 at approximately 107 UTC .. a high frequency pulse from the NEXRAD RADAR appeared out of Lacrosse Wisconsin.
I put this watch/alert out on Facebook — watch the area for up to 72 hours for weather to develop , usually severe or odd weather conditions follow these RADAR pulse events
However, even in the screen shot that he provides of the forecast there is a forecast for a 20% chance of snow associated with the approaching front so that contradicts his claim that the forecast was for all clear. The forecast discussions for 24 November (which predates Dutch's "flash" forcast) mention that light snow may accompany a passing front:
Here are area forecast discussions from mid day on the 24th.
So NWS was forecasting a front to pass mostly dry with moisture aloft with the frontal passage and snow only reaching the ground in limited amounts to the north and east of La Cross and likely not at all in La Cross. And that was the NWS forecast on the 24th.
That weather is exactly what is depicted in the radar screen shots he provides. It never snowed in La Cross and the snow to the north was very light, mostly not reaching the groud because the airmass was so dry below the 500mb level. The weather on the 27th was neither strange or odd in that region. The weather was associated with a short wave passing to the north and dragging through a dry front. Most of the weather associated with the front occurred far away from the supposed "frequency pulse" nearer to the passing shortwave. Such weather is common in that area this time of year.
As for the "frequency pulse". It is of the same origin as is delt with in another thread. It is incorrect data fed into the mosaic creating a display error.

ANOTHER SFC-700MB FRONT/TROUGH APPROACHES ON TUE
WITH AN INCREASE OF MOISTURE/CLOUDS ABOVE 500MB. THIS ONE LOOKS
TO HAVE WEAKER FORCING/LIFT AND LESS MOISTURE THAN THE ONE PASSING
