Bob Chill Posted February 1, 2015 Share Posted February 1, 2015 Bob, thanks for this - great explanation and easy to understand. Simplistically, I've learned to look at the 500h map as a highway for our storms. But one thing I have a hard time understanding is when the pros refer to "heights are low", etc when doing PBP of model runs. Low heights equate to flat 500h and high heights refer to non-flat 500h isobars? I just can't wrap my head around that concept for some reason. The easiest way is to look at the closest height line # over your house. If that # is increasing or moving north as you move forward in time then it means heights are increasing or vice versa.

snowfan Posted February 1, 2015 Share Posted February 1, 2015 There's some funny **** out there on facebook. Someone posted to the S&S page that the temp at their place in west York was 36 and that their forecast was going to bust. They responded by telling the person their sensor was faulty. I guess they didn't realize that Thomasville (the official reporting station for York) was reporting 37. Link to comment Share on other sites More sharing options...
Bob Chill Posted February 1, 2015 Share Posted February 1, 2015 I was thinking it was way more complicated than that. Thanks! Depending on what you are looking for it can be much more complicated. I described a short lead technique that was threat specific. Long range you'll hear me post things like "lowest heights centered out west" and things like that. It's relative or comparative to heights in the east. How low and how high means a lot. Trough axis is very important. Spacing is another important consideration. How sharp or broad a trough/ridge setup is means a lot irt sensible wx. Link to comment Share on other sites More sharing options...

87storms Posted February 1, 2015 Share Posted February 1, 2015 Comparing model frames to previous runs is good except for when a wave significantly speeds up or slows down. Then it's not so easy to tell the differences from a hobbyist perspective. My concern going forward for our region is if the pattern trends towards a Midwest to northeast one.

snowfan Posted February 1, 2015 Share Posted February 1, 2015 Based on radar, I'm not sure how totals are going to pan out in PA. Radar looks like a mess. Maybe this will be a bust for all but NNE. Link to comment Share on other sites More sharing options...

winterymix Posted February 1, 2015 Share Posted February 1, 2015 There still can be some frozen at the onset. The 850 mb chart shows the freezing line to be across and a bit south of much of the MA at this time. Of course there will be strong WAA to nose away the froze.
