9:30 p.m. update — We’ve increased our snowfall forecast to at least 1 to 3 inches for most of the area
Computer model simulations have slowly ticked up Friday’s projected snowfall over the last 24 hours and so, we’ve decided to increase our accumulation forecast slightly. Here’s what we’ve updated:
In the zone in which we were previously predicting 1 to 3 inches, we’re now calling for 2 to 4 inches.
In the zone in which we were previously predicting a coating to 2 inches, we’re now calling for 1 to 3 inches.
In addition to the model support for increasing totals, we think this will be a powdery snow that will accumulate a bit faster than if it were a heavy, wet snow. Freezing temperatures between about 27 and 31 degrees should allow the snow to stick and pile up without much of a problem.
That said, it’s important to remember that this system is somewhat moisture-limited and snow totals may be variable. Both bust and boom totals shown in the above map are in play.
We still expect the snow to move in between 3 and 6 a.m. Friday.
Stay tuned for updates in our new forecast that will post at 5 a.m. Friday at washingtonpost.com/capitalweathergang.
