3/2: 1.0”

17.5” season total. Think that puts me just above median snowfall since I’ve been in Columbia (starting 09-10 winter). 

3/12: 1.4”

18.9” season total. Best Nina since 2017-18.

McLEAN WINTER 2025-26 SNOWFALL: 19.9" 

Average: 19.9" (100%)

November: T
11/12: T | Stayed up late hoping for something more substantial, but there were still some light flurries.
11/30: T | Morning snow/sleet mix changed to rain.

December: 3.7"
12/5-6: 2.2" | The return of the mythical December 5th snowstorm. It brought extreme cold for early December, with my high of 29. Included a nice little round two starting at 10 PM, not finishing until around 1 AM. R1: 1.9", R2: 0.3"
12/11: T | Scattered flurries in the morning.
12/14: 1.5" | A busted forecast (from 2-4"). 0.25" QPF fell as 1.5"—awful ratios.

January: 9.2"
1/1: 0.1" | An early morning snow squall with strong winds.
1/17: 0.1" | A morning burst of snow accumulated to a dusting.
1/18: T | Three hours of afternoon flurries translated to a trace. The mulch was slightly whitened, though.
1/24-25: 9.0" | EDIT (2/22/26): revised from 10.2" down to 9". Reanalysis showed 0.6" QPF falling as snow and 1.8" QPF falling as sleet. This equates to 5.4" of snow at 9:1 ratios and 3.6" of sleet at 2:1 ratios, for a total of 9.0".

February: 4.9"
2/6: 0.1" | A few hours of moderate snow gave a nice wintry scene for the area. It was a nice refresher for the snowpack.
2/12: T | Some morning flurries.
2/22-23: 4.8" | Rain to potent snowstorm. Warm temperatures at onset lead to a decrease in accumulations.

March: 2.1"
3/2: 0.6" | It was a nice and beautiful March snow. I didn't bother to measure, so I'm splitting the difference between DCA and IAD.
3/12: 1.5" | Some surprise anafrontal snow brought a heavy coating. Credit to @MN Transplant for the measurement. (SUBJECT TO CHANGE - waiting for final measurement from @MN Transplant.)

1/24-25: 8.5" 

2/22-23: 2.0"

I think I'm good for at least one more 0.5". Maybe a sloppy car topper on April 11th

I hate 0.25"'s but stats padding is a necessity here.  They add up.

Seasonal snowfall to date: 14.25"

12/5: 1.75"

12/14: 1.0"

1/24-25: 8.5"
