  1. 12z Euro is a solid hit, and cold enough for everyone!
  2. You can use T if snow fell then melted on contact. You don't need stickage for a Trace.
  3. I think we could be doing an inch an hour with this band if it was sticking. The model doesn't know if it's sticking, it just knows its falling.
  4. It's coming. We just had full switchover in Silver Spring. Edit: It's waffling a bit.
  5. So close to flipping over in Silver Spring... A few bombs are making it through.
  6. There was some thundersnow last night near Frostburg. Thinking hit some wind turbines up there..
  7. From looking at the mesonet sites, looks like the magic number for transition is about 35.5...
  8. One heck of a thunderstorm (for February) about to go through Richmond. Lightning and small hail.
  9. RAP is overdoing the rates, it wants a 3"/hr deathband in DC with the TROWAL. I don't think I've ever seen 3"/hr with a TROWAL on a rapidly exiting system.
  10. NAM even wants to skunk State College, my gosh. lol, what a coup.
  11. H5 is back even a tad further west at Hr 0. Good grief lol.
  12. That's rain. For elevations near sea level, with surface temps above freezing need at least 925mb temps at -2C for SnowTV.
  13. If this was just colder with some CAD to start, this would have been beautiful with the "new" track. 700mb low slides right over top of us with the 850mb low just over southern MD. *chef's kiss*
  14. Also the northern stream s/w is a bit faster than expected 48 hrs ago (this is also what's bringing in the cold air aloft), and perhaps a tad stronger.
  15. No, it's the timing of how the southern stream cut off low ejects, it's been getting slower / further west. Allowing the northern stream s/w over SK/MB/ND to kick it further south.
  16. Additionally, I still don't trust relying on a TROWAL to deliver us the goods without an incipient CAD regime in place in front of an apps runner.
  17. Stacked cut off low's are always hard to time ejection, but agreed. This is particularly bad. Compounded by the fact it allows time for the "cold" air to filter in from Canada.
  18. It's because the GFS has gotten stronger with the s/w aloft. If you look at 300mb at 02-13 00z, the area of greatest difluence was over SW VA but with the stronger s/w, it's moved 100 miles NW towards KY/S OH. That isn't much aloft, but damn does that 100 miles mean a lot for advection at the surface with the apps in the way.
