Yeah there’s likely some of that with the decent wind flow and high PWATs… but the highest totals being on both the east (Waterbury, Stowe, Morrisville, et) and west slopes (Underhill to Montgomery) makes me think the boundary just stalled and waffled in this area too. Or the flow was just right in a critical Froude number to evenly distribute rainfall on both sides of the barrier.
Last night on radar the line of convection sort of stalled and then got run over by slug after slug of moisture training over it. It almost went east of here but then backed up westward again into the Spine.
Always some orographics in play but I think synoptically it was just where than boundary stalled. It’s still over the region now as that meso-low moves up in E. NE. It’s finally moving east again as the low reaches our latitude and tugs it again.
I feel like the Whites had a more orographically induced rainfall with that southerly flow jamming moisture into them.
