RU848789 Posted March 6, 2013 Share Posted March 6, 2013 Ray - any advice for how best to do snow measurements in a storm where some of the snow is likely melting as it's falling? I'm tired and don't have time to look it up and figured you'd just know off the top of your head. Is it still measure every 6 hours or is there any allowance for intermediate measurements? Thanks. While we're at it, haven't followed the Philly thread, but what are your thoughts for Central Jersey (especialy Trenton to Edison)? Link to comment Share on other sites More sharing options...

While we're at it, haven't followed the Philly thread, but what are your thoughts for Central Jersey (especialy Trenton to Edison)? You can measure as often as necessary; the 6-hour rule applies only to clearing the board. The actual snowfall is the maximum depth measured during that 6 hour period between clearings, even if it was an hour after you last cleared it. As far as my thoughts... the 0Z NAM was drier, some of the other guidance was a bit wetter. The east wind off the ocean seems to be doing its thing, so now its kinda wait and see. I'm nervous my coating-2" might be a bit low for TTN, but I'm not changing anything at this time. Edison could make out a bit better being further northeast.

phlwx Posted March 6, 2013 Share Posted March 6, 2013 NWS PHI THE FCST BECOMES MORE PROBLEMATIC THIS EVENING. THE PRECIP SHUD TRANSITION TO SNOW AND THEN ITS JUST A QUESTION OF HOW MUCH QPF IS LEFT. BOTH THE EC AND GFS HAVE SOME QPF BETWEEN 07/00Z AND 07/06Z AND MUCH LESS BETWEEN 07/06Z AND 07/12Z. SO IT REMAINS TO BE SEEN HOW MUCH QPF IS LEFT AND OF COURSE, WHAT THE TEMPS ARE.SO, FOR NOW, WILL CONVERT THE WINTER STORM WATCH TO A WINTER WEATHER ADVISORY FOR ALL COUNTIES WHERE IT WAS IN EFFECT AND ADD MERCER, MONMOUTH, OCEAN, SOMERSET AND HUNTED IN NJ. DEPENDING ON WHAT LATER GUIDANCE DOES, IT THE ADVY CUD BE UPGRADED TO A WARNING FOR PORTIONS OF THE AREA. Link to comment Share on other sites More sharing options...

famartin Posted March 6, 2013 Share Posted March 6, 2013 Interestingly, PHL is reporting rain/snow mix. 39/33. Obviously nothing is going to stick at that temp...
