This week is going to be generally cold, but the below average temperatures won’t be as sustained as they looked to be a week ago. That has caused the expected, cry, winter is over, another warm winter, and so on. I’ve been asked, “why keep posting on the medium and long range if what I said a week or more ago changes”? My answer is “that’s why I post on the longer range so much”. Patterns adjust and evolve. So, I try to keep you in the loop as to how the pattern is progressing. This post will get into the meteorology a bit….. Y’all can skip to the bottom if you want to see my final thought.
As I said, this week starts out cold, but we will see some warming for the second half heading into the weekend. The air temperature is going to be average to slightly above average……In other words fairly seasonal. So, it won’t be a torch by any stroke of the imagination. The week ahead, is looking basically benign with a possible storm this weekend.
I will try to post on the Euro Weeklies in the Weather Group sometime today; if not today then tomorrow. But on here we can talk a little about the American and Australian ideas of what’s ahead.
I called for the EPO (Eastern Pacific Oscillation) and WPO (Western Pacific Oscillation) to go negative, but they haven’t. The ENSO isn’t looking quite the way I thought it would at this point. But we still do have the warm spot in the GOA (Gulf of Alaska). The reason for all of this has to do with the MJO (Madden-Julian Oscillation). It was in the warm phase 6, this is helped in assisting the EPO and WPO to stay positive. With the positive phase we had warmth. We also have had this undercutting Pacific Jet (PJ). The PJ hasn’t been kind to our storm tracks, which has also helped contribute to how the winter has shaped up so far.
All the models do generally snow the next 30-40 days as being cold. The American CFSv2 (The Climate Forecast System Version 2), Australian BOMM (Australian Bureau of Meteorology - POAMA Coupled System) and the American GFS (Global Forecasting System) are showing overall cold, with the American GFS model the farthest east with the cold. The BOMM was higher into phase 8 last week. But it has since fallen off to a more weak phase 8. The Euro model is the farthest west. So, while they support the idea of cold, they each have it centered differently and various extents of the cold. The IOD (Indian Ocean Dipole) is an important player in the MJO. It was in a strong cold phase for last Fall heading into Early winter. Then it reversed to a warm phase signal. The last few days have seen it rebound a bit. Right now, it looks right around average, to slightly positive. This will limit the influence of the IOD for the rest of this winter and into spring. The reason the MJO has acted atypically this year, very well could be due to the expansion of the Indo-Pacific warm pool. But that is a discussion for another time. The signals are mixed, so things could go either way at this point.
What the MJO does is going to be critical to how things evolve over the next several weeks. MJO phases eight through three are considered cold phases this time of year. When we look at the IOD the Indicators for cold in the Eastern CONUS signals are mixed. Many of the models are taking the MJO into the NULL phases, which means there is no/or little MJO influence on the pattern. We have seen cold winters that had the MJO going NULL, the most notable was 2015. If it enters the NULL, what phase it was before then is important. If we enter NULL from Phase 8 we have a better chance of seeing a lot of cold, as opposed to entering NULL from phase 6.
So, the bottom line is …. I’m sticking with my idea for overall cold for February. I do think the pattern will turn to more sustained cold…. but I wouldn’t be surprised if it went the other way.
