  1. Same out here in the suburbs. Many of the early flowers are up, and some trees/scrubs are budding. .
  2. Famous last words. Today is as marginal as marginal gets. .
  3. GFS upgrade occurred as expected this morning. .
  4. The environment with this potential is really not that far off the environment from that day. Guidance the past day or so have really slowed things, with most of the potential being across MO/S IA now. .
  5. It has been re-scheduled for March 22nd. .
  6. Ice pellets where I am just west of ORD right now. .
  7. Speaking of... Spann doing a terrible job today. Kept mentioning numerous times that storm would miss Tuscaloosa by a long shot, when in reality it had been running parallel to I-20 for quite a while.
  8. 1.8” at ORD, 1.6” at MDW and 2.0” at RFD. .
  9. KORD 151951Z 09014G22KT 1 1/2SM -SN BR BKN009 OVC017 M01/M03 A3009 RMK AO2 PK WND 09026/1904 SLP195 SNINCR 1/2 P0006 T10111028 2” depth means at least 1.5” from this event at ORD. .
  10. KORD 151851Z 09017G23KT 1/2SM R10L/2400V5500FT SN FZFG VV007 M02/M03 A3015 RMK AO2 SLP215 SNINCR 1/1 P0008 T10171033 .
  11. A combo of pea size graupel and 1” flakes right now in this bright band. About 1/8SM vis and gusting to about 40MPH. .
  12. Event is already going to be ending within an hour or so around here. .
  13. There have been a few instances of TSSN out towards the Lee/DeKalb Co border the past hour or so. .
  14. Went from nothing to solid SN and white ground here within about 15 minutes. .
  15. Indeed. 2” soil temp still in the upper 30’s here, and probably a bit higher down there...So I’d imagine any accretion is on elevated/colder surfaces. .
  16. Can see CC quickly crashing east on KLOT and SE a bit on ILX. Probably all snow to near I-39 now, north of I-80. .
  17. I’ve been pretty much think 1-3” for the CWA along and north of I-80. However, I fully agree that there is much more upside potential. If thermals work out as the GFS/RAP and others show, definitely could see an axis of 3-6”+ into the CWA. .
  18. With colder air not filtering in until right before things are getting going, there isn’t going to be sufficient time for the already mild surfaces/ground to catch up. Add in that’s it’s noting going to get colder than the upper 20’s most likely either. Maybeee elevated surfaces towards the end, but that’s a stretch depending on how long precip actually lasts.
