I'm not sure if there's an advantage to an extra balloon release. The regularly scheduled 12z RAOB from RNK and IAD would help to see if there's anything hanging out aloft that could mess up the snow and that would be just as the goods start to materialize.

HRRR is going to make a lot of friends. Snowy through the morning.

^that's actually a decent chart and I hope you do these for future events

Yup. Going to be very interesting to see what happens this afternoon with temps. We might wind up being a bit colder than guidance which isn't surprising. MAV/MET mos has been running a bit too high of late and as others alluded to earlier in this thread, being just a degree or two colder in the column for a few hours more tomorrow will have big implications between 2" - 4" of snow then a mix, or people boom and get 5"+.

Ice palace. Having ZR/IP fall at night without significant warm air punching north is a recipe for

The products were updated to say, "around one tenth to one quarter of an inch".

Yup. Typical La Nina climo storm...you nickel and dime your way towards climo. Considering that we had almost nothing to track last year inside of D15, this is at least something.

Looking at the QPF panels for the 3k NAM and RGEM there appears to be a nudge up and better distribution of the moisture from the cities N&W.
-
SPC's 12z HREF is running. 00z HREF was 0.5" to 1.0" mean QPF across the I-81 to I-95 corridor.
-
Warnings coming out shortly.
-
Previous runs of the HRRR has outright precip hole after the initial round of moisture. The 00z run appears to have that pretty much gone. Things lighten up, but it's not a nasty dry slot or anything.

00z HRRR at 14z Thursday, (HR 38), DCA is upper 20s at the surface.
-
I have the 00z HRRR out to HR37 on COD and it looks pretty good from EZF north.
-
How wet?
-
There's been a last minute trend for drier and deamplification within HR36 this winter. I'm hoping the 18z Euro isn't sniffing out a trend.
-
I think that map's a bit pessimistic. Aloft looks a bit colder and there's going to be sleet on top of that.
-
Euro is 6" - 10" for Montgomery County.
-
Is it drier areawide, and if so, by about how much?
-
Yup. Nothing worse than praying the night before the event that we get the cold air in at 3am when the precip starts at 5 and then waking up to 34/33 and white rain.
-
^oh man that is NICE
-
Winds ripping pretty good in Westminster. Temp down to 37.
-
If you're in the mid 20s with moderate precip, it's going to accumulate.
-
GFS give Short Pump the ole' middle finger.
-
Hush. Never doubt the ability of something to pull the football away last minute.
-
GFS is noice for BWI, DCA, and IAD. Even down to EZF does better.
