Drought Update – January 27, 2024

Every week on Thursday, the Drought Monitor LINK is updated for every state in the U.S. plus most territories.

 

 

 

 

And there is another source of information on drought from certain groupings of states that operate what is called a Drought Early Warming System (DEWS). They sometimes have webinars and may issue reports without having a webinar. Not all parts of the U.S. are covered. These groups of states seem to issue reports every two months. I am only showing the recent reports since a month-old report at this time of the year can be misleading.

To get to that part of this article where I provide these reports you may have to click on “Read More”. I provide maps for all of the existing DEWS.  And other groups of states report on precipitation, streamflow, and reservoir status which overlaps a lot with what is covered by the DEWS. So I plan to write about the activity of both kinds of groups. Today I am focusing on the DEWS.

The polar vortex is acting up – January 24, 2024

Last month there was some concern that we were having a Sudden Stratospheric Warming Event. It seems that it did happen but in a fairly minor way and the resulting cold intrusions of Arctic air seem to have not lasted for very long. I came across this posted article on Climate.Gov attributed to Laura Cisto and Amy Butler. I am reproducing their article here except for the comments it received. You can access the article with the comments HERE. The comments are always quite interesting and the authors typically reply to those comments. And that process can continue for some time which is why I have provided the link to the Post by Laura Cisto and Amy Butler.

It is difficult reading and not everyone will want to dig into it but it is here for those with a deep interest in weather. Where I have comments, I have put them in boxes within the article. For those with an insatiable curiosity, THIS explanation of Sudden Stratospheric Warming Events will probably quench your thirst.  The blog post that I have in this article describes a recent mini-SSW event that was somewhat unusual.

Colorado River Basin January 17, 2024 Water Supply Forecast Discussion – Posted January 20, 2024

The mission of the National Weather Service Colorado Basin River Forecast Center (CBRFC) is to produce river, flood, and water supply forecasts for the Colorado Basin and the Great Basin in support of saving lives and property and to enhance the region’s environment and economy.

In this article, I am providing a summary of their Water Supply Forecast Discussion released on January 17, 2024.  The situation is not very good. However due to a wet winter last winter, the reservoirs are mostly in good shape. 

 

I have also included information on the current reservoir storage levels including a few that are outside of the Colorado River Basin.

The image below shows part of the area covered in the CBRFC Report.  The map shown here is only the Colorado Basin. The Eastern Great Basin is to the west of this map. The maps shown in the article cover both basins but are not as scenic as this map.

Map showing both the Colorado Basin and Eastern Great Basin.

Most of the information presented in this part of the article is from a summary report (Link) issued by the Colorado River Basin Forecast Center. January 17, 2023, Water Supply Forecast Discussion
The Colorado Basin River Forecast Center (CBRFC) geographic forecast area includes the Upper Colorado River Basin (UCRB), Lower Colorado River Basin (LCRB), and Eastern Great Basin (GB). It is one of many similar organizations within the National Weather Service. They are all different. In the future, I will try to pay more attention to some of the other River Forecasting Centers but they do not all go out of their way to provide reports to the Media. But the Colorado River is a special situation in a way due to the problems complying with the Colorado River Compact. But all our rivers are important.

At this time of the year,  we are hopefully adding to the snowpack for future snowmelt. Additional information is available on the Center website (click HERE), there are certain graphics that update daily. And now I provide the main part of their new forecast discussion summary. I am copying directly from their document. My comments are in boxes.
