Snow mixing in with rain in Timonium. Seems to be 50/50 or so.

Are there any websites that have updated "official" observed snowfall totals aside from the NWS Public Info. Statements?

Most recent SPC meso discussion from 9:39 AM EST. Mesoscale Discussion 0055 NWS Storm Prediction Center Norman OK 0839 AM CST Sun Jan 25 2026 Areas affected...Eastern West Virginia and Virginia into the DelMarva. Concerning...Winter mixed precipitation Valid 251439Z - 251745Z SUMMARY...Snow has mostly transitioned to sleet from eastern West Virginia, across Virginia, and into the DelMarva. DISCUSSION...Strong warm air advection has supported moderate precipitation rates through the morning across West Virginia/Virginia and into the Mid-Atlantic. The 12A IAD RAOB showed a warm nose slightly below freezing at around 750mb with very strong (80 knot) southwesterly flow at the altitude of the warm nose. As such, this warm nose is quickly warming/advecting north and surface observations of sleet across northeast Virginia and Maryland confirm this transition. Any areas that remain snow this morning across Virginia and Maryland will likely transition to sleet within the next 1 to 2 hours given this strong warm air advection aloft. Expect precipitation type to remain sleet even as this warm nose continues to warm given the very cold temperatures at the top of the boundary layer (-15C) at the KIAD, KRNK, and KGSO 12Z RAOBs. The moderate precipitation will continue with sleet accumulation of 0.1 to 0.2 inches per hour expected. ..Bentley.. 01/25/2026

Pinging starting to noticeably increase here (central Balt. county).

Snowfall rates picking up nicely in central Balt. county. It really is wild to see just how fine the actual flakes are.

Armed and ready.

I'm just now noticing that the two maps have different titles ("Event Total Snowfall Accumulation" vs "Expected Snowfall: Official NWS Forecast") so perhaps they're using separate data.

Ha. They just released an updated one at 1:17am that is a tad more conservative.

Latest map from LWX (12:41 am). The red-shaded 18"+ area is starting to creep into the favored N/W zones.

Are any models capable of showing the potential for convection/thundersnow at this range?

Finally starting to changeover here (central Balt. county). Noticeable uptick in the amount of snow mixing in during the past 10 minutes or so.

A few flakes appear to be mixing in, but otherwise 98% cold rain in central Baltimore county. Good times.

Really enjoyed tonight's Profs and Pints: What We Know About Snow presentation tonight in Baltimore with Jeff Halverson of CWG. It's mostly basic-level discussion but still fascinating and highly recommended for fellow snow-lovers/weather-nerds.
