  1. Gonna be 20" reports in Cook. Early candidate would be that Evanston/Winnetka area, given about 6" down thus far already.
  2. Total there so far between 5-6" already, when factoring in snow since last evening.
  3. I don't think there has been a RAP run yet that hasn't had 15"+ at ORD.
  4. Not our territory, but Little Rock NWS reported 10.6" recently...and it's still snowing.
  5. That RAP run has 3-5” of snow down by 12z in a corridor from C IL into Chicago metro. That’s unlikely to happen, so shave a bit off the total at the end of the run. .
  6. Have had -SN at ORD for a little over 2 hours now, but only a T of snow thus far. More recently better -SN has developed, with some actual accumulation now.
  7. 18z Euro didn't really shift much...But was drier/weaker. Edit: I lied, not drier...Actually a bit wetter. However, much less snow on the snow maps.
  8. Snow depth as of 6PM will be 15" at ORD. (14.5" actual amount)
  9. Has a lot to do with what is going on aloft... How far north and when exactly the wave goes negative tilt has the say in if this ends up NW or SE. in addition to the amount of ridging ahead. .
  10. 18z GFS bumped NW, and para GFS tick NW.
