NorthArlington101 Posted February 13, 2014 Share Posted February 13, 2014 Hires NAM supports all snow through 12z for me/DC. does it have the sleet already approaching old town, and does it just stall it? because if it doesn't, while its a nice though it seems meaningless.

Then moves south a bit at the next panel (7am). Obviously, nowcasting is the way to go, but figure looking at guidance helps a little too. Link to comment Share on other sites More sharing options...

MN Transplant Posted February 13, 2014 Share Posted February 13, 2014 Does it keep coming west or does it drift back east? It keeps coming west a little, but it looks funny. Might be the 13km resolution of the NAM. Link to comment Share on other sites More sharing options...
Random Chaos Posted February 13, 2014 Share Posted February 13, 2014 Take a look at the 925mb temp on the HRRR. It intrudes about the same distance as the NAM, but it isn't complete coverage and then gets cut off as the cold backfills: http://rapidrefresh.noaa.gov/HRRR/jsloopLocalDiskDateDomainZip.cgi?dsKeys=hrrr_jet:&runTime=2014021305&plotName=temp_t3925&fcstInc=60&numFcsts=16&model=hrrr&ptitle=HRRR%20Model%20Fields%20-%20Experimental&maxFcstLen=15&fcstStrLen=-1&resizePlot=1&domain=t3 Link to comment Share on other sites More sharing options...
