RAP starting to tickle NW the last couple runs....22z now gets Jimmy with the edge of that CCB band.

It does seem like there's a touch more precipitation further northwest than modeled with that 700mb frontogenesis band (it's snowing at KISP), model products seem to have the lift there but they have it very dry, maybe it's a bit more moist than progged?

Yeah I think they maybe overplayed the dry air....this isn't a classic dry air scenario either....not like we have ripping N or NW winds in the midlevels. And the sfc def ins't a dry north drain....winds are off the water, albeit light.

Soundings do show some midlevel dry air, but it doesn't appear that it is that hard to overcome with this precip shield. Just about every model had zero measurable on LI until after 00z...GFS had a couple hundreths. We'll see how heavy that stuff actually is. Aren't a lot of stations out there.

Will I know lightning has a significant role in these storms.  With the explosion over the last two hours, and especially in the last hour, with 200 plus additional strikes every 20 minutes off the East Coast in the warm sector where the instability support has really gotten going today as the secondary low developed and starts to intensify.

My driveway camera shows flurries but I could be hallucinating and I’m not overly excited enough to go outside to do the ole ‘finger to light’ check.

We have a strict no masturbating while posting policy, here.
