This period of negative pna has caused roughing in Denver and the mountain region causing massive snowfall these past few weeks but will the pna turn positive to give similar conditions to the eastern US?
I have to say, these model runs are getting ridiculous, especially when they are run 4, 3 and 2 days prior to a storm. This storm coming up is becoming a joke as well. All 3 models were showing an all snow solution, now we are looking at a bit of snow then all rain in central to southern jersey. Forecasting seemed to be more accurate back when I was in grade school (late 70's - early 80's)!
It is a shame you guys below ruined this site. I used to love Rob's insights as he is the best weatherperson in the Philly area…….now all I get to read is you trolls below talking about nothing and jamming up the page. Shame that Rob's hard work on this site has gone to waste. Thanks Trolls
