tombo82685 Posted February 19, 2015 Report Share Posted February 19, 2015 Curious to know what is the coldest thickness phl has ever been down to if that is possible. I mean models have sub 490, when was the last time that has ever happened? Quote Link to comment Share on other sites More sharing options...
Rainshadow Posted February 19, 2015 Report Share Posted February 19, 2015 IDK. I might still have a book from 1994. Quote Link to comment Share on other sites More sharing options...
Rainshadow Posted February 19, 2015 Report Share Posted February 19, 2015 On the NARR, there was a 495ish on 1/19/94 (-5F). Tough to know because you might have low thicknesses, coldest air relatively speaking more aloft and no snow cover. Quote Link to comment Share on other sites More sharing options...

If these thicknesses occurred in January phl would no doubt in my mind be below zero. Quote Link to comment Share on other sites More sharing options...
