bluewave Posted December 20 Share Posted December 20 We will be dealing with the same issue to start January that we had December. Models have been underestimating the strength of the Pacific Jet beyond 10 days. So now they are beginning to see a trough the West instead of the ridge several days ago. 500 mb heights over the NEPAC and WNA have been verifying lower than the long range forecasts have been indicating.

You can see in the ext products that any trough in the east will be transient. Our only way out was this Decembers with the PNA but the pac never slowed down.

We’ll probably start the month with the trough over the West and warmer than average temps around the area. Then a storm will run to the Great Lakes or hug the coast with colder air rushing behind. The screenshot is the long range model bias showing up. So the spread out trough from west to east across CONUS longer range is smoothing out the storm tracks. When the lows eject from the SW transient Southeast Ridges will emerge in the fast flow allowing the storm tracks to run to the Great Lakes or hug the coast. We have seen this pattern time and time again over the years with low in the West under a Canadian +PNA. 1 1 Link to comment Share on other sites More sharing options...

Doesn't mean it's going to happen with every storm from now till March..Sometimes patterns change..Yes we've been in a snow drought but it always goes back the other way..that's why they have averages. 3 Link to comment Share on other sites More sharing options...
brooklynwx99 Posted December 20 Share Posted December 20 also, just logically speaking, in order for us to go from the overextended jet like we have now to the supposed retracted jet SE ridge pattern in late Jan that some are advertising, there HAS to be a period where the jet is in a favorable position for WC and AK ridging and a mean trough in the east. the jet can't just magically hop from one place to the other 1 Link to comment Share on other sites More sharing options...

brooklynwx99 Posted December 20 Share Posted December 20 also, if the Pacific jet is also going to be stronger than forecast for much of the winter, wouldn't that mean that the retraction on the extended guidance for late Jan into Feb is overdone, shifting the prospective Aleutian ridge more into AK and the WC, leading to a colder E US pattern? but nobody is using that logic in that fashion for whatever reason 1 Link to comment Share on other sites More sharing options...

I called for a -1 to +1 pattern for this month back in early December which is right on track when you average out the 7 local stations currently at -0.5. A back and forth pattern with warm ups and cool downs. The model forecasts issued on December 1st missed the warmth from mid to late month which I was pointing out three weeks ago with my posts about the Pacific Jet verifying faster than forecast. I also highlighted the mismatch potential back in October with the +PNA we have seen. But that there were competing influences that were different from past La Niña mismatch Decembers. 2 1 1 Link to comment Share on other sites More sharing options...
