For those who may have missed the January update, here is the key graphic.

I provide the link to the full report published on Monday in the body of this article. The above shows in the top row the updated outlook for January. The bottom row is the three-month outlook issued on December 21. Do I think that outlook is still valid? I have to say no. The changes made to the January Outlook raise questions about the three-month outlook. But NOAA says the changes were due to the MJO and AO. The MJO will not impact February and March based on what happened in January. It is not clear if the changes to the AO will carry into subsequent months. And it is not clear that the changes in the outlook were fully explained in the discussion issued with the updated outlook. So we will be in suspense until the new Seasonal Outlook is issued on January 18, 2024.

NOAA Realizes it is a Powerful El Nino and Updates its January 2024 Outlook. January 1, 2024

By Sig Silber January 1, 2024weather2 Comments

At the end of every month, NOAA updates its Outlook for the following month which in this case is January of 2024. We are reporting on that tonight.

There have been some very significant changes in the Outlook for January and these are addressed in the NOAA Discussion so it is well worth reading. We provided the prior Mid-Month Outlook for January for comparison. It is easy to see the changes by comparing the Mid-Month and Updated Maps.

The article includes the Drought Outlook for January. NOAA also adjusted the previously issued Seasonal Drought Outlook to reflect the changes in the January Drought Outlook.

The best way to understand the updated outlook for January is to view the maps and read the NOAA discussion. I have highlighted the key statements in the NOAA Discussion.

I am going to start with graphics that show the updated Outlook for January and the Mid-Month Outlook for January. This is followed by a graphic that shows both the Updated Outlook for January and the three-month outlook JFM 2024. So you get the full picture in three graphics.

Here is the updated Outlook for January 2024

For Comparison Purposes, Here is the Mid-Month Outlook for January.

There have been some significant changes. Remember, it is the top set of maps that are the current outlook for December. Until now we were not sure that NOAA (actually their CPC Divison) had moved the storm track sufficiently south given the strength of this El Nino as measured by the Nino 3.4 Index. All of a sudden they have.

The top row is the Updated Outlook for the new month. There is a temperature map and a precipitation map. The second row is a three-month outlook that includes the new month. I think the outlook maps are self-explanatory. What is important to remember is that they show deviations from the current definition of normal which is the period 1991 through 2020. So this is not a forecast of the absolute value of temperature or precipitation but the change from what is defined as normal or to use the technical term climatology. The three-month map was issued on December 21, 2023. Is it still valid?

Some readers may need to click “Read More” to read the rest of the article. Some will feel that they have enough information. But there is a lot more information in the rest of this article.

Status of Western Water Reservoirs: December 30, 2023

By Sig Silber December 30, 2023weatherNo Comments

I used to report on Reservoir Levels. The article this evening is a second attempt at doing this. I have now been able to include New Mexico information.

It contains a lot of information. I will be republishing this article periodically and adding and improving to it. What I am providing today has images that should update automatically. But I also have provided links to those images and additional information.

At this point, it is far from perfect but a start. It is particularly important because in many cases the water in reservoirs comes from last year’s precipitation. So with uncertainty as to how this El Nino winter will evolve, we need to monitor the amount of water we have in storage.

Let’s get started.
