6z Euro went the wrong way for Friday. Yesterday's 6z Gfs is looking like a blip. I just hope we can skip the zr and ip. Nothing exciting about spending Christmas weekend day inside.
Keep in mind that the models have been horrendous in the 4+ day range, so it's hard to believe anything beyond 48hrs imho, good or bad. So even if 1 or 2 showed a storm beyond 4 days, chances are it's a lie.
18z Gfs has the 546 height line through northern Baltimore City while the Nam has it just south of DCA. IF the Nam is closer to correct with the cold air draining further south, that's enough to make a difference for some.
