I have been very interested to see how the RUC and NAM models
match up to the local temperature forecast from the National Weather Surface
(as the surface temperature is the biggest factor in determining the strength
and height of lift).

The National Weather Service called for 78 degrees as the high for today. My
outdoor thermometer measured 79 at one point during the day. The Leesburg
Airport (closest weather station) showed the high for the day at 74. This lower temperature was most likely
due to the high clouds that dominated this blue day. We know from previous
experience that RUC and NAM (and presumably whatever model the NWS is using)
don't handle these clouds that well.

The NAM model called for 76 degrees. The RUC model called for 70. Looks like the
NAM model continues to be a better predictor.

Pilots did fly. (I didn't as I have a cold.) The lift was weak, as forecasted by
both models, but those who got up got to over 4,500'. The NAM forecasted 5,2000'
top of lift and the RUC forecasted 3,400'.
