Super late. This past year didn't have many intriguing weather events IMBY but show of you may have had something a bit more interesting/impactful. 1. I'll have to go with the hailstorm that occurred on April 15th. Got a bunch of dime/penny-sized or so hail that ended up coating the ground a bit. 2. It was pretty cool having a destructive-tagged STW with a thunderstorm line-segment approaching from my west across Loudoun county on August 3rd, though it weakened a bit before moving into MBY with gusts into the 30s (mph) and heavy rain. The back to back 4"+ snows IMBY from January was nice. While not IMBY... the June 5th tornado outbreak was something fairly impactful, particularly across northern MD.

Yeah. 0z 3kNAM showing winds 1km above the surface of 40-45kts within the mixing layer Wednesday afternoon w/ the 0z HRRR being super aggressive briefly showing winds of around 50kts within the mixing layer Wednesday afternoon. Wednesday, especially the afternoon, could be quite windy.

This lasted until after 3pm when precip again intensified into a light rain/snow mix before changing to all rain by 3:40pm.) 12/20/2024: T(A drizzle of rain/snow (8:30am-9am). A period of light snow between 10:30-11:15am, briefly approaching moderate intensity between 10:35am and 10:50am. Flurries continuing until midday. A few more flakes in the 6pm hour based on radar returns.) 12/24/2024: 0.1" (Light sleet started around 6:30am occasionally mixing with freezing rain through about 9am or so (more IP than ZR). Precip was very light but below freezing temps and a cold ground allowed for whitening of hard surfaces. Was originally going to call it a trace but with all of the 0.1" reports immediately surrounding me and taking into account sleet pellets piled at least two pellets high in depth... a tenth of an inch is the final measurement I went with making it the first measurable white stuff of the season for me.) 1/03/2025: 0.2" (Brief light rain/snow/graupel shower around 2pm. Heavy snow associated with a developing snow squall between 2:50pm-3:15pm with a brief brake in intensity to light snow between 3:00pm and 3:05pm. A second snow squall from 4:13pm to 4:25pm. Snow was light to moderate with the second squall until 4:22pm when rates briefly became as heavy as during first squall. Peak snowfall rates from both squalls in the 1-2"/hr range.) 1/06/2025: 6.2" (First flakes around or shortly after midnight on the 6th. Light snow becoming moderate at times by 2:00am lasting through 7am before becoming intermittent and tapering off to a few small flakes/crystals by 9:45am.

Flurries taper off by 8:15pm.) 1/19/2025: 1.6" (Some wet snowflakes mixing in with light rain in the 9am hour. Off and on light rain w/ a wet flake or two until 1pm when more snow started mixing in until it was all snow by 1:30pm coming down at a moderate clip. Snow lightened up and turned into a snow/graupel mix, then mainly graupel with a little sleet mixed in during a good chuck of the 2pm hour. More snow started mixing back in around 2:45pm before becoming all snow with a legitimately heavy burst between 3:10pm and 3:16pm (2"+/hr rates). Snow became light afterwards before picking back up to moderate intensity by 4pm. By 4:30pm snow tapered off to flurries which continued on occasion into the 6pm hour before ending all together.)

Those yellows were fun here in Herndon. Large aggregates w/a moderately heavy snow burst. I'm now near 0.5" for the evening.

Lol! Second time the Monument gets struck this week.

Wondering if those 50+ DBZ reflectivities near Fairfax are all snow or some kind of mix.

Rain/snow mix here in Herndon.
