SACRUS Posted February 7, 2013 Share Posted February 7, 2013 Peyote and poorly written code? "RPM: Rapid Precision Mesoscale model. A numerical weather prediction system based on the Advanced Research Weather Research and Forecast system (WRF-ARW). RPM generates forecasts out to 24 hours with updates every 3 hours in the United States and every 6 hours outside the United States. Precipitation forecasts are calculated from half-hourly instantaneous precipitation forecasts output by RPM." Link to comment Share on other sites More sharing options...

NorthShoreWx Posted February 7, 2013 Share Posted February 7, 2013 great videos... Stellar video!!! NorthShoreWx, I really appreciate those video's. I grew up in Oyster Bay and remember that storm. Great stuff! The videos aren't mine, but I'm happy to help share them. I experienced that storm growing up in Syosset and have a few photos on my site: http://www.northshorewx.com/19780207.asp Link to comment Share on other sites More sharing options...
nyblizz44 Posted February 7, 2013 Share Posted February 7, 2013 The NAM is getting there but the initial vort is still pretty far north for my liking through 36 Do you fear a repeat of March 2001 when the phasing occured much later than forcast? I remember seeing those stunning 24-36 inch forcasts even on the Upton site & then whoosh....Nada except for a measly 6 inches on back end snows Link to comment Share on other sites More sharing options...

MJO812 Posted February 7, 2013 Share Posted February 7, 2013 The Nam seems slower than the other models. Link to comment Share on other sites More sharing options...
SnowGoose69 Posted February 7, 2013 Share Posted February 7, 2013 Through 42 its very close to 12Z at 54 but the primary does appear to be a bit more south so there may be an earlier phase...big may there because the NAM tends to become clueless after 48, it may look good through 48 then do something odd Link to comment Share on other sites More sharing options...
earthlight Posted February 7, 2013 Author Share Posted February 7, 2013 Looks like it will be sloppy again for the most part ... but the changes should be enough to hammer New England this run at the very least. Link to comment Share on other sites More sharing options...

Dosh Posted February 7, 2013 Share Posted February 7, 2013 Hour 51. Looks like the NAM is back to its 12z solution. No CCB blitz for our area, but definitely not as terrible looking as 18z Link to comment Share on other sites More sharing options...
uncle W Posted February 7, 2013 Share Posted February 7, 2013 Feb. 8th 1994 had a storm that started over Texas and moved NE and another one two days later..both storms had some mixing and glaze...9" for both storms on my block...This time around it might not be as cold as 1994 and it could wind up like the 2/13/93 snow/sleet/rain event...that storm ended up with 3" of slop...
