That's the 3K but it's not rain per se but a serious downsloping situation in the valley. Seen this in many past storms. To the east and west ends up doing better.
It looks more and more favorable for us as long as it keeps slowly shifting east with each run. If it doesn't then that allows the thump to end a few hours earlier and a better chance of BL problems to spoil it.
Based on what I've been seeing so far up to almost game time, I could see this thing actually shifting close to 50 or so miles further to the east before it starts. It seems to be doing that incrementally almost every 6 or so hours with each run.
We'll see what the BL levels truly are with that. Kuchera fluffs stuff up a little too aggressive. Proved it many times with reports out of Bedford, MA ground truth.
