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.

11/15/2022: T (sleet) 12/10/2022: T (sleet) 12/22/2022: T (rain w/little SN/IP mixed in) Snow totals as of 12/22/2022: T

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

Hopefully you had a good anniversary today!

Relatable... minus the wife part. Welcome aboard!

The earlier the thaw, the earlier the reload!

We'd finally get back our long lost MOD risk day. TOR: 15%, WIND: 45%(hatched), HAIL: 5%

2021 comes to mind. Weird peak temps across the main airports.

33F rain > HECS ... Carrot Cake > 33F rain Down to 33F earlier with rain and a glorious jog in it. #blessedindeed Stay safe and enjoy your carrot cake today!

Down to 20F at IAD this morning. Currently 23F. Could be a cold one with high clouds already overspreading the region that will slowly thicken throughout the day.

Yeap. January 25, 1985... The year that you're not too fond of.

I've noticed that the data from CPC analogs apparently only goes through 2009. Do you or anyone in here know where can I find analogs from 2010 onwards?
