Falls Church 6" now, so >2"/hr rates Went out for a walk with the dog. You can see the shadows of the individual flakes on the ground from the streetlights.

Yeoman Posted February 13, 2014 Share Posted February 13, 2014 What would I be looking for? Would that be an actual observation or in the radar? Look at the waves in this radar shot Link to comment Share on other sites More sharing options...
EHoffman Posted February 13, 2014 Share Posted February 13, 2014 5 inches and piling up in Rockville. I had video but it was so abrasive on the thread. Idk how to post just the link without embedding the video. Link to comment Share on other sites More sharing options...
MidlothianWX Posted February 13, 2014 Share Posted February 13, 2014 Straight-up ZR in RIC now. Temps are warming quite a bit faster than progged - I've already reached the 31-32 range. If the sfc stays below freezing we will be in a fairly bad spot, as the RAP shows at least .50" qpf between now and the dry slot. If we warm up, 33 and rain. 25 and SN++ to this, all in one night.

wxmeddler Posted February 13, 2014 Share Posted February 13, 2014 Is Correlation Coefficient 1 the best to identify the changeover line? Yes, lower CC = mixed P-Types Link to comment Share on other sites More sharing options...
WxMan1 Posted February 13, 2014 Share Posted February 13, 2014 Is Correlation Coefficient 1 the best to identify the changeover line? Yes, CC is the best dual pol tool to use... The more you get under .98-1.0, the more the hydrometeors do not "correlate" to one another -- i.e. indicative of a mix. Someone with access, can you please post the latest CC image from LWX? Thanks in advance.. Link to comment Share on other sites More sharing options...
MN Transplant Posted February 13, 2014 Share Posted February 13, 2014 Is Correlation Coefficient 1 the best to identify the changeover line? I like that the best. There is a definite line south of Fredericksburg, but I want to know what is going on with that blob south of Andrews. Link to comment Share on other sites More sharing options...
Ian Posted February 13, 2014 Share Posted February 13, 2014 What would I be looking for? Would that be an actual observation or in the radar? i don't see them as much now but earlier it was pretty visible .. see the lines in the band Link to comment Share on other sites More sharing options...
