Not that it really matters at this point, but FWIW the UKMET looks a little further south than last night.  Maybe a hair faster, as well.

 

Compare:

It matters because UK is juicy..almost 1" in the triangle with a solid .8" across most of area.

It's 24 at noon. Unless the sun comes up, we won't hit 30 for sure.

 

Hell, GSO ticked down a degree in both air temperatures and DP from 11 AM for the noon observation.  We're back down to 22/-6.  Real good job, HRRR and RAP.  I think I was supposed to be well above freezing by now if you go by their runs last night.

RAH mid-day update...

AS OF 1145 AM MONDAY...MORNING UPDATE: LITTLE CHANGE WILL BE MADE TO THE PREVIOUS FORECAST. THE MAIN DIFFERENCE WILL BE AN INCREASE IN ICE ACCUMULATION AREA-WIDE...PARTICULARLY IN THE TRIANGLE. SIGNIFICANT UNCERTAINTY PERSISTS WITH REGARD TO THE EVOLUTION OF PRECIPITATION THIS EVENING INTO TONIGHT...IN PARTICULAR THE TRANSITION FROM SLEET TO FREEZING RAIN ACROSS PORTIONS OF THE NORTHERN AND NW PIEDMONT BETWEEN 00-06Z TUE...LENDING BELOW AVERAGE CONFIDENCE TO FORECAST PTYPE AND ACCUMULATIONS. WITH THE ABOVE IN MIND...FURTHER CHANGES TO THE ONGOING FORECAST APPEAR UNNECESSARY AT THIS TIME. A MORE DETAILED DISCUSSION WILL BE ISSUED FOR THE AFTERNOON FORECAST PACKAGE PENDING A MORE DETAILED ANALYSIS OF ONGOING OBSERVATIONAL TRENDS. -VINCENT

Sounds like anything could happen in regards to how much snow or ice we get.

Apparently, they don't model clouds.

This cold snap coming up is one we'll tell our kids about. Arctic front snow looks like it'll break out across the southern piedmont on wednesday, the NAM even gave us up to a tenth of QPF.

 

Agreed.  Single digits two nights in a row is impressive.  With highs not getting above freezing two days in a row.  Good stuff.
