Temps were lacking for all three. It snowed her for the mid December storm, it was freezing rain for New Years , and if either of the past two events (Friday and today) had gotten precip this far north it would have been snow. I guess it’s all about perspective but when Tennessee Mississippi Louisiana, Alabama get snow, temp concerns aren’t at the top of my list 1 Link to comment Share on other sites More sharing options...

We haven’t had an organized precip event this year and we are 11 days into January. Unless I missed something. We need precip before temps are a factor. When it’s partly cloudy what difference do temps make? First I am totally fine with constructive criticism! This is an open forum and anyone is free to challenge and disagree with anything I say and hopefully everyone knows that. But second there is a WHY that matters behind the what (no precip). What I’ve suspected and been saying and HM just confirmed is that one of the big problems we’ve had getting any of the southern waves to amplify in this split flow is the lack of cold. I know they seems counterintuitive but cold doesn’t suppress the flow does. Now there is a correlation because a colder airmass will press the baroclinic zone (tighter temperature gradient between warm/cold) south and the suppressive flow of the NS will likely be further south. But without enough cold there wasn’t enough temperature gradient to fuel the storms. I don’t want to start an atmospheric physics class so I’ll grossly simplify this but it’s that temperature gradient (baroclinicity) that fuels our mid latitude storms. Without cold there is less gradient and less potential energy for storms. Result= weak POS systems along the weak thermal boundary in the south that don’t amplify and come north. The systems that did come north were weak and during periods of ridging when the weak temp boundary came north. But even then they were too weak to initiate what we needed. That perfect track storm back around New Years could have worked if it amplified more. But it was pathetic so we got light rain (talking about the second wave) . Had there been more cold in this pattern the results likely would have been less dry. Looking ahead with a more canonical Nina look in the pac we don’t want too much cold and suppression. But that -NAO -pna -epo look is intriguing. The level of blocking being shown now would suppress the SE ridge but the -pna would create a SW to NE flow towards us. That’s potentially a fun pattern.

If we end up just N of that gradient it could be quite the fun! So maybe we nix the clipper pattern altogether and head straight into SWFE?

Im not PSU but....Trof digs in the west, flat SER thanks to -NAO raging keeping it at bay. Waves eject out of SW and head NE and overrun the cold air locked in via confluence under the 50/50.

The axis of cold air intrusion looks rather similar to the 1959-60/2005-06 composite GIF that HM posted on his twitter a few days ago Both post-SSW, both similar Ninas (at least 05-06 and this year, that is)..
