2/10: From this morning to this afternoon, apparently there are these things called grass and soil under the #snowcrete. 🤔 After 17 days, I was starting to have doubts. #Maryland #thaw

2/9: As the mid-Atlantic now has a week of above freezing #temperatures in the forecast, there is quite a bit of #seaice and #snow to melt. #Thaw

An impressive low pressure system swirls off the US East Coast in the North Atlantic.

For awareness, the @nws.noaa.gov has just released a tool to visualize certain #severeweather and #wildfire threats based upon climatology, or a historical record of past events.

As the “ #BombCyclone ” moves away from the east coast, and the skies clear, here’s a view of where the #snowpack has accumulated…or in the case of the rest of us, where it still remains

Further increases in confidence for an impactful winter storm are noted across the Carolinas with greater uncertainty still farther up the coast.

How cold has the #ArcticBlast been? Well, there are signs.

@nws.noaa.gov Director Ken Graham presented on NOAA’s modeling grand challenge at #AMS2026 this morning. He announced that the NWS is moving to MPAS as its modeling dynamical core, with his #1 moonshot goal being a global, fully coupled 3-km Earth prediction system using MPAS.

7 p.m. — Precipitation finally about to taper
The end of the sleet and freezing rain is mercifully in sight. Radar from 6:45pm (shown below) and short-term models both suggest the precipitation should quickly taper from west to east across the region between 7 and 8 p.m.

Fascinating local temperature variations... TEENS west of Beltway but upper 20s to east... this is a rough dividing line between more sleet and more freezing rain.
Crazy that it's 18 on American Legion Bridge but 28 at Reagan National Airport
