Can see the difference clearly on h5 out west... and in the SE. Much bigger ridge out west just off the West Coast at 00z compared to 12z and there is no semblance of a h5 low on the 00z run. Comparing 00z 198 to 12z 210
192 shows 1035 HP in Quebec... 1007 SLP just south of HSE... lets see what precip maps show in a min
ETA -- not much... light snow in SW VA
Out to sea it goes at 198... so no big wound up system like 12z was
