Before landfall but not at landfall. Kind of makes sense since it was moving so slow and the strongest winds were on the back side of the storm. The core would have interacted with land for about 6 hrs before the strongest winds got onshore.
The HRDPS sometimes beats the American mesoscale models on convective setups in the northern half of the country. HRDPS was the only one to have the line this far southwest.
If I told you that we would get near record setting Greenland blocks in December and March would anyone of the long range forecasters have predicted we'd get no snow from either?
