Breaking: 18z GFS Shifts Substantially Further East in Track

The latest GFS just shifted the track of Monday/Tuesday’s storm even further to the east.  I am looking forward to seeing the next run of the European to see if it follows suit.   Bottom Line: if the storm system is weaker and tracks further east, colder air trapped at the surface would hold in longer producing more of a snow and ice event. gfs_mslp_pcpn_frzn_neus_11 gfs_mslp_pcpn_frzn_neus_12 gfs_mslp_pcpn_frzn_neus_13 gfs_mslp_pcpn_frzn_neus_14 gfs_mslp_pcpn_frzn_neus_15

Updates to come tomorrow when we the latest Euro models are available.

  1. Woo Hoo! Does that mean more snow for Gaithersburg? Or a dangerous Ice storm? Your forecasts are always on target! Thanks so much!

  2. Oh boy! We got ourselves some hope for a stow storm! Some of the other forecasters are saying flooding is an issue, not anymore. How big would accumulations be with this track?
