Comments
Here's the real skinny, NWS has not the kahunas to publicly define the real event information. There are things going on in the upper atmosphere which will influence the directionality of this event. Furthermore, spin the dial - Tasselmeyer is gloating on a dusting, Bass is flippin to the tune of 1-2 and old Ken Phillips is throwing down 1-2 today and another 2-4 tonight and good ole shorty Norm he waffles like a willow on his values. Bottom line is get the real data look at the dew point convergence at your elevation, look aloft to the upper flows, look south to the tracking of the current dopplers. Move on folks there is nothing here to see if it was Jim Cantore would have had a 9:06 PM flirtation with his beloved lap top spewing gloom for the metro's to the north but alas like Heide Cullen the Weather CHannel ad revenues are dropping like a rock
