Having lived in this area my entire life of over 50 years, could be my biggest storm ever in December!!!!

Better than 0z in the game, off for a walk

Colder at surface as well, DCA not above 34 at surface

7 and 10pm colder

4pm. Still smudge SE of 6z near the Beltway

1pm

WB EURO wed 4am, tick se with 0c so far.

WB GEFS individual members....(grocery store panic in Frederick county has begun as I return home)

There is still room for another 30 or so mile shift either way by Wed night. Exactly where the R/SN line will be TBD. EPS 0z v 6z. Slight tick SE. At least the bleeding to the NW stopped. Does it hold here or continue to drift back either way to be TBD.

Look at the 925 line in Montgomery County Md 2C to 0 C about a 30 mile shift SE between 0z and 6 Z EURO.

WB Euro L placement 7pm Wed

Not big change but agree that it edged back se this run. Did not continue NW. I mean every 40 mile shift is huge either way.

WB 6Z v 0z 925

WB 6z EURO v 0z snow map

WB 6z EURO

WB 6z EURO 7pm, also tick se

WB 6z EURO 4pm, again little se of 0z

WB 6z EURO 1pm wed tick se

Euro is rolling...may the force be with us....

Let’s hope EURO moves toward GFS

The 40 I think is at 3pm. By 10 pm surface temps are falling toward freezing and rates are still good.

6z gfs sucked for dc. Way to close for comfort even into loudoun I think verbatim Wed. 10 pm to 4am a lot of snow will be sticking everywhere if GFS verified. Rates should overcome surface temps slightly above freezing in the corridor and se.
