Drove from Colesville area over to Potomac/Rockville during the 6am hour. Not terrible but definitely some snow covered spots - especially where tires aren't hitting from traffic. Side roads are pretty much snow covered except where treated. Very pretty! Just wish I wasn't at work today.

12z HRRR is cold smoke for everyone west of the bay it seems.

Did you mean 18z?

My gut is telling me this is the official start of winter for our area. 

Yeah the start of our string of slightly lesser failures  

Flurries in Odenton, MD.

Hrrr doesn’t get the squall line far enough south for the dc metro, but radar looks better

Time for weenie-ism #454359845 "Time to nowcast!"

Everyone loves DC crushed at 138…then the Bob Chill face emoji.  That would be fun again

Watching that line build over northern VA.    It's easy to ignore it given the huge swath of intense rain departing to the east, but if you look closely at the CAMs, there are signals for some isolated heavy cells moving across the area over the next 3-4 hours.     Temperatures should rise ahead of the it, and there is a little bit of propped instability.....     Curious to see if these things are anything more than brief heavy rainers.   

I had actually shut down my radar programs. Worth watching! 

My pressure is down to 989! Impressive!

DCA- 52 mph

IAD- 49 mph

BWI- 47 mph

 

If those are the peak gusts at the end of this - the earlier modest model run gusts (other than the NAM) did exceptionally well. It's interesting that as we closed in today, the models got much more aggressive. 

993.5mb on the PWS
55 degrees and the high for the day. 

 TVS showing up on GR2AE near Popes Creek. 

Two reports of trees down on BW Parkway. 

Let's see if the line can bring gusts up for a bit. 

Port Royal, VA seems like they might be getting smacked right now. 

There have been some go-arounds at BWI it looks like - and a few diversions.

Is it a mesonet station or one of the SHA weather stations?

M80 mph Bay Bridge.

Is it a mesonet station or one of the SHA weather stations?

Very respectable radar signature showing up from like Stanardsville down towards the SSE from there.

I’m not sure what it says about me but I’m extremely tempted to fly my drone up and see what happens … for science ofc 

I lost an Autel drone a few winters ago in 35-40mph winds

where is the wind?

Wherever the snow is.

A derecho to end all derechos. 

997.2mb on my PWS right now. 52.2 degrees and that is the high so far today IMBY.

Wonder if the wind mixing down means the lower level stable air has eroded?

I wonder if that little "dryslot" is the warm front coming through. 

DCA is gusting to 35kts

Snow and sleet at 47 I call bs lol

I've seen flurries at 50 when the warm layer was very shallow. But I'm in Silver Spring and it's just pouring. 

Starting to hear the wind roaring up in the top levels of the trees. Nice movement of the trees too. Going to be a lot of tree down calls coming in throughout the evening. Stay safe!
