anyone know for certain whether all those snow maps for the different models always include sleet with the snow?

 

I don't know for certain, but I'm pretty sure that the tropicaltidbits maps do and the meteocentre maps don't.  meteocentre has separate maps for rain, snow, sleet, and freezing rain.

North and west of Baltimore is starting to look real good.

 

Yeah.  Actually north and west of I95 through Maryland is starting to look good.  In the NAM map I posted above, DC gets more snow than Baltimore.

The only reason the nam doesn't have euro/ukmet/gfs/rgem totals is because it's a warm nose outlier. If it's right we all still do well. If it's wrong we do better and also have a valuable piece of intel to put in the pocket for the next similar setup

Been a heck of a ride with these models. Finally, in the 9 th inning, the GFS sees what the EURO has been seeing for days.
