HURRAY FOR PVA

Both models show nice PVA Saturday night into Sunday morning. Which is great for lift and increased vertical velocity. QPF is showing plenty of moisture for this and the NAM is showing if indeed we have a 10-1 ratio of snow we could see over a foot. Temps aren't that cold for the large light fluffy we se at -12 degrees C. So its inevitable the snow will be heavier and more wet condensing the accumulations. I think somewhere in the 8-10" range.
This storm doesn't seem to be as long lived as the previous "storm". However we do have the Jet paralleling the low so it wont kick it out to fast, but unlike last time the was a high pressure system infront of the cold front slowing it down. This is Colorado so wait ten minutes and all will probably change!

  1. 10-1 SLR is not accurate for this part of the country.
