Looking at soundings for late tonight - pre-dawn tomorrow, with some elevated instability I wouldn't entirely be surprised if a few heard thunder especially east of I-95.

Well... looking at soundings for late tonight - pre-dawn tomorrow, with some elevated instability I wouldn't entirely be surprised if a few heard thunder especially east of I-95. #SOON #Aroundthecorner

@yoda @Kmlwx Knock yourselves out. https://www.spc.noaa.gov/exper/outbreaks/# See you on the flip side when you're out of the wormhole.

IIRC, and don't quote me on this, the guidelines for measuring ice accretion is taking the average of the amount of ice on top of a twig and below the twig. Ex: 0.12" ice accretion on top of the twig and 0.02" of ice visible below the twig gets you 0.07" of ice accretion (0.12 + 0.02)/ 2 I'll double check though.

Sleet here. Hopefully it will change back to ZR in due time. 28/23 at IAD.

Indeed! I mean Bob Chill has been waiting for his foot of ice. For me an ice storm w/ at least one inch of ice accretion would be nice. Afterwards, hopefully we can score a legit areawide severe event and/or decent tropical event.

... and even if you do, the boundary was dropping south at the end of the run. You were about to flip to wintery precip.

@MillvilleWx @csnavywx @high risk Now that we are in a break before our next event it's time for Curious George to strike. Now, as you were discussing back on Friday, this model can overdo convection. But let's pretend that these were real soundings. What diameter do you believe that aggregates would reach in soundings like these? Also, what would you guess that the snowfall rates would be?

Still a great storm. I was getting 2"/hr 1-1.5" diameter italian meatballs at the top of the hour.

It's likely overdone as others have mentioned in the thread for this event but lol. Softball-sized parachutes?

53F at IAD. February 1987 redux.

Rain/Sleet w/ a very mangled flake or three in Herndon, VA.

Just for lols but check out the Omega and elevated CAPE combo in this sounding over northern Delware. At the least it shows the potential with this one fronto-wise.

I actually DID get some ice pellets in Herndon about 15 minutes ago. 5th day in a row with frozen precip.

There seems to be a very light band of precip moving through northern VA which, believe it or not, may be hitting the ground in some spots. Is anyone getting anything? Pinging?

DCA has hit 33F so far today.

The image above shows total precip for the past 6 hours. On pivotal it shows instanteous precip rates at a given time.
