Because we are most likely going to waste moisture on rain or mix most of today... I think its a good call. HRRR gives us an inch after a lot of rain.. GFS has us on Eastern edge with heaviest snow in mtns which will surely happen
GSP usually starts low and gradually increases as the event closes in but they dont have much time, especially if places get 3-6 inches like some models show..
One thing that I have noticed is the EURO and UKMET especially have moved the SLP quite a bit closer to the coast and a little stronger too 1008 vs 1005... That helps with more precip near the Blue Ridge and cools the column with heavier precip
