Down to 20.8 in Great Falls. 

A few brief power outages this afternoon, which is better than we sometimes do in wind events. 

Can confirm flash freeze on our deck, furniture, and grill.  Driveway has not yet caved.  28.6

Steady temp fall continues. Down to 30.6. 

Still have a few flurries flying. Temp now down to 32.9. 

Temp now falling steadily. Down to 35.6. Still snowing.

Pouring sleet?

Yes. Typo. Only lasted ~5 minutes, but enough to lightly cover the deck and mulch. 

Sleet mixed in immediately with the line in Great Falls. Now poring sleet. Still 43. 

Looks like the front went through IAD between 8 and 8:05. 

42.6 as we wait for the front in Great Falls. 
 

Quite the temperature yo-yo overnight. Jumped briefly to 52 before quickly settling by back to 41-42. 

Creeping up to 37.2 in Great Falls.  Anyone know if they are sanding the roads outside Philly?

Some sleet mixing with the rain in Great Falls as the intensity picks up.  34.7 degrees.

29/25 in Great Falls. Feels like snow (which means it will rain). 

20.5 for the low in Great Falls. 

Bullseye run for us.  Looks like rain for Philly.

Philadelphia normal annual snowfall is 22.4 and Washington Dulles is 21. Wilmington is 20.2 and Baltimore BWI is 19.3. Very similar.


.

True, but the N&W Philly suburbs (a better comparison to IAD) get substantially more snow than PHL.

Philly will almost always do better than the DC-area with Miller Bs (where latitude often makes a difference).

32.4 and plain rain in Great Falls. 

Back down to 35 in Great Falls  

Impressive temperature contrast in the car thermometer on the drive home from DC: 46 downtown, 41 in Arlington, and 37 at the Beltway & Georgetown Pike.

I suspect the western zones in Fairfax, Prince William in NOVA will drive decision making 

In theory yes, but I’m skeptical that Fairfax will decide based on temps/ice out here in the hinterlands. There was one event last February where we had early morning ice and 31-32 degrees but much of the county was just wet. I don’t recall that leading to a delay. 
 

That said, I think tomorrow will most likely be a delay. 

Also heavy frost in Great Falls this morning.  22 for the low.  Now up to 38.

18 for the overnight low in Great Falls.
