HRRR dew points

      The HRRR was extremely aggressive with higher dew points ahead of the front in the upper plains this weekend.     The 33h forecast had values much higher than in the analysis, and it seemed to be an in-situ type of scenario instead of advection.   Attached are 24h and 33h forecasts for the HRRR and NAM3 and the RTMA analysis at 21z.

It indeed looks like the HRRR was a bit bullish, and too broad with the higher dewpoints.  Does it do this regularly?
