Seems to be coming in slowly. Out to HR84 atm.

You chasing?

Just me being Curious George but does anyone know what the current GLAAM state is? I'm guessing that it must be higher(more +) than one would normally expect given the Nino-like pattern in a low-end moderate Nina?

And... so ye anti-carrites don't kill me for my bias ... MERRY CHRISTMAS TO ALL!

A fellow young man of culture I see . Merry Christmas to you!

IAD down to 7F so far.

Very true. I'm actually talking about the lows areawide in general though. Ex: IAD forecast low was 7F. With wind we'd usually end up at ~9F give or take a degree (courtesy of mixing). I'm just happy to be fully performing with something other than heat lol.

Well I'll be... we're, for once, actually at the least hitting the forecasted lows with a bit of wind. We are usually end up a few degrees above forecast... nice.

At 18F IAD has now snagged it coldest temp thus far this season.

Hope you recover quick! Good thing this is indoor weather w/ bitter cold + no snow... well for me anyways.

Do you have power back yet?

IAD gusted up to 48kts (55mph) this hour.

And with that IAD is officially below freezing at 31/19.

Just had a 5 minute or so burst of moderate/moderately heavy? snow (trace accumulations). Winds picking up. Herndon, VA.

I'd actually wondered lately whether I was spoiled because those strings of good Decembers in the 2000's happened to occur when I was a kid. IMBY and FY in Herndon, VA the last 3 Marches that had a warning level snow event here was in 2018, 2015 and 2014. Meanwhile the last time I experienced a warning level event in December was in 2009. Snow month rankings for the majority of this region: 1. February 2. January 3. March 4. December

Graupel... not sleet ...

Just had a 20-30 second burst of heavy graupel that quickly coated the street in Herndon with that line... then it was back to lightish rain and a breeze. Those 20-30 seconds were neato though.

Interested in what precip type @Round Hill WX and @midatlanticweather are getting with this line.

Now there's a Flood Warning for much of northern/central VA. My new weather radio made sure I knew it.
