That still seems pretty low at this point, but I suppose they're waiting until the 12z suite is complete before raising any alarms. Given the rush hour impacts, I imagine this is certainly worth a WWA for the entire LWX region.
Yes, but it’s most severe in the medium and long range. In the short range it’s minimal. But of course that’s an average across lots of space and time, so it could be wrong either way in any particular location and time.
Yeah. I was looking at 3k NAM soundings around DC/Balt and it's pretty minimal and mostly at 900mb actually.
The models account for precip evaporating/subliming during descent (I'm 99% sure...) so can't really explain it.
Something is majorly weird with the GFS and that 850mb dry layer that develops between 0z and 6z Wednesday. I don't see how that is consistent with 0.2-0.5" of liquid equivalent. Pivotal shows the same info as TT, so it's not that one is plotting bad data. Just bizarre.
That gfs sounding is just bizarre. I don’t understand how that jives with moderate precip. Compare that to the NAM sounding Bob posted which makes much more sense.
Lol, just as the pole and Atlantic look to shift better, the Pac wants to take a crap. I’m still skeptical until it happens since this has been advertised a few times in the last 6 weeks only to either not happen or be very transient.
