Saturday Feb 27 Preview

This is a preview because again, I will be out of town this evening.  Update will occur around 11:00 PM.  Also, I'll text Jason in the morning if I see anything interesting to add.  This morning I was able to relay to Jason that there was a +5 temp change between 6,000 and 9,000.  A real inversion!

Today's lesson: Wind above 25 mph at 6,000 +320+wind gradient+large inversion between 6,000 and 9,000= lennies! 

 For Saturday:
  • Again, I would expect frost conditions to subside between 8:00 and 9:00 AM
  • Early cloud cover may be about 50%, but by 9:00 should be only ~30% or less
  • Winds at 6,000 should be about 32 mph at 310
  • There will be a smooth, easy wind gradient with winds at FL240 of just 55 mph
  • There will be a slight temperature inversion in the 12-15,000 range
  • Thermal activity will begin in the late morning and will probably be disruptive of  low-down wave by about noon.  Get out early for wave or later for circling.  Your choice.
  • Thermal activity to 4-5,000 AGL in the afternoon may provide lots of opportunities to investigate the scenery around Marion.
  • Surface winds should be light all day, with no gusts to worry about from NW or WNW
But seriously: Early Saturday flights may well reveal how important the strength of the inversion is to the creation of a strong Shiflet Wave.  Please go investigate safely and post your flight and comments on OLC.
