Any opinions on Len Randolf's Northern Lights prediction? Much drier air will be over Utah tomorrow, so there will then be a huge drop in the humidity levels. Blue skies and plenty of sunshine will then become the weather order of the day through at least the middle of next week. On an astronomical note; there is a 20-40% chance of seeing a very small part of the Northern Lights tonight and Friday night. Meteorologist Len Randolph, Live 5 Weather HD. Thursday, 4 August 2011.
