WinterWxLuvr Posted December 1, 2014 Share Posted December 1, 2014 18Z GFS has 0.25"+ falling here between 09Z-21Z Tuesday with temps at or below freezing. That's actually more precip than the 18Z NAM had for the same period. Can't be right.. Euro is dry. Link to comment Share on other sites More sharing options...

winterymix Posted December 2, 2014 Share Posted December 2, 2014 This front was better than 90% of the sorry excuses for east coast fronts. Down 26 degrees from the high.Plse correct me if I'm incorrect but this is what I get from the 0Z NAM:The 925 mb temp. chart maintains a cold wedge east of the Appalachians until 18Z tomorrow. The 700 to 850 mb chart is warm nose city all the way to northern PA. Conclusion: light sleet and freezing rain/freezing drizzle for NVA/NDC/CMD. Maybe a few flakes late night with wet bulb depression early in the process of saturating the column. Also, many areas may have more freezing rain than sleet at sunrise.

usedtobe Posted December 2, 2014 Share Posted December 2, 2014 00z NAM has the QPF max in a small swath in the southern DC suburbs including EZF back SW to CHO... sleet sounding ftw The 00Z NAM sounding has warmed and the warm layer wet bulb is 3.3C which usually means the snowflake completely melts, when that happens it does not refreeze and the result it rain. Both DCA abd IAd now have the warm layer too warm to support sleet if they are right. It's close as below 3C in the warm layer will get you sleet. FDK and MRB still are sleet sounding through 18Z.

midatlanticweather Posted December 2, 2014 Share Posted December 2, 2014 Sleet and rain mixed in Purcellville va! Eta: I have not been able to further confirm that I have pingers. I decided to take a walk and check every flatime surface. Nothing now..either I hallucinated or I was wrong or it was brief! Link to comment Share on other sites More sharing options...
nj2va Posted December 2, 2014 Share Posted December 2, 2014 2z HRRR suggests a mix in NW DC between 11-12z before changing back to rain. Mix remains just to the N&W of DC during the morning commute. Precip shield also trended NW on this run from 1z. Temps in the mid to upper 30s so yeah.. Link to comment Share on other sites More sharing options...
