I WAS low-key wondering about the steep low-level lapse rates, weak instability and deep northwesterly flow for tomorrow after seeing today's 12z CAMs. Apparently the SPC is low-key watching as well.
...Delmarva/Chesapeake Vicinity...
Moderate northwesterly deep layer flow is forecast across the region
as a strong upper low moves offshore the Northeast coast and an
upper ridge slides slowly eastward across the Midwest. Surface
dewpoints are forecast to increase into the upper 40s and low 50s
beneath modest midlevel lapse rates, resulting in weak instability
during the afternoon and evening. Furthermore, forecast soundings
show a well-mixed boundary layer developing as temperatures warm
into the 70s. While severe storms are not expected given weak
instability, a couple of convective showers and/or storms could
produce locally strong gusts.

Some things just don't change lately.
Ex. The near sub-tropical entity dropping 2+ inches of rain with the western edge along- you know the interstate continuing last years theme.
As always, persistence until it isn't anymore. But this persistence has been persisting persistently for a while.
It's going to change... eventually.
Yeah. March climo and the tendency for overnight storms to our west to sink south of modeled are really keeping my expectations in check for Sunday atm.
The last time, from my memory anyway, that DC was in a hatched zone was on a Day 3 outlook for April 6, 2017.
The last time, from my memory anyway, that DC was in a hatched zone at gametime was on February 24, 2016.
Okay. Let me try this.
@Mrs.J @losetoa6
I hope you had great birthdays last week!
@NorthArlington101 @fourseasons
Happy Birthday to you both!
@Always in Zugzwang @vastateofmind
Happy Birthday to you both in advance!
Did I miss anyone?
Three possible years (I don't know for certain. I'm just basing this off of the weather pattern that I remember at those times.) are 2010, 2012 and maybe 2020?
Obviously, it also depends on the reporting location.
Oh wow. I actually never knew that... nearly 18 years near the airport and you'd think I'd know this.
I love learning new things though.
48/46 w/ drizzle at IAD.
Yeah. It's all more spread out than before requiring scrolling on mobile (it wasn't like that before). But like you said, they bothered which = it's being used.
*Sidenote: Is runway 19 and 01 at Dulles really oriented from 190* to 10*? I always thought it was due north to south. Perhaps just some kind of approximation?
April of 2019 was better than usual as a whole for these parts. The April 14-15th event could've been something memorable if timing was + or - 12 hours. A lot of moonlit skies between the storms that night once the mid-level dryslot moved overhead. Make that sunshine and add 5-10F then...
