El Niño

81% La Niña Conditions

October 16, 2024 by casey.matzke

Pockets of drought relief exist, but not much. In fact, 74% of the state is abnormally dry or worse, up 4% from last month. Underlying dryness and dry, drought cured grasses will support low to moderate potential for wildfires with steady 10-15 mph winds as frontal activity increases. As forage transitions to fuel, rangeland managers are monitoring perennial grass response throughout the Concho Valley as some counties received over 12” of rainfall in September alone.

As we move from a summer to fall-like pattern this week, the Outlook +Water Report from October 5th keenly acknowledges sea-surface temperatures in the Central Pacific (defining the status of the weather phenomenon known as the El Niño Southern Oscillation) are under neutral conditions, but sea-surface temps continue to drop suggesting a transition to La Niña conditions in September-November (81% chance). However, current dynamical and statistical models show the La Niña period promises to be weak and short.

The current U.S. Seasonal Drought Outlook shows drought development over the eastern third of Texas and in the Panhandle. With the increased drought designation, temperatures over the next 3 months are expected to be above-average with rainfall deficits for Far West, Panhandle, and Eastern Texas.

As with any drought monitoring or transitions into La Niña this fall and winter, West Texas Rangeland managers know to prioritize keeping the ground covered, maintaining residual forage, rotating livestock, and plan, plan, plan.

Drought Update!

August 21, 2024 by casey.matzke

Did you know that East and Northeast Texas received two to four times the normal amount of rainfall in July? Unfortunately, the other half of the State did not do as well, as some places in West Texas only received a half an inch of rain. With the increase in rains in Eastern areas of the State, Lake Travis saw 78,000 acre-feet of runoff pour into the basin! Even with that amount of runoff, Lake Travis still remains at less than 50% full. The figure below shows the reservoir storage for Lake Travis. In looking at the figure, our numbers are above where we were for 2023 and a little bit more than where we were in 2011.

La Niña has been the dominant subject of the summer. According to this month’s update, projections are suggesting a shift to La Nina in mid-to-late summer. Looking at the figure below, there is a 45% chance that La Nina occurs during the July-August-September months. Moving ahead on the figure, we can see that shifting one month over, there is a 70% chance of those La Niña conditions occurring in August-September-October months.

Looking ahead at the three month drought outlook, you can see in the figure below, that West Texas will remain in drought conditions. There is also the possibility for drought conditions to develop in the Northern Panhandle.

In looking at the 3-month precipitation forecast, Texas does not look to be receiving a greater chance of rain. As you can see, the East Coast is set to have above normal chances of rain, with East Texas catching a tail end of that wave. On the other side of that, the Northern Panhandle is forecasted to receive less than normal rainfall. The figure below explains more of the 3-month forecast.

Texas + Water – June Update

June 26, 2024 by casey.matzke

Hurricane season is coming fast and furious! NOAA is predicting an above-normal hurricane season, forecasting 17 – 25 named storms (winds higher than 39 mph), 8-13 hurricanes (winds of 74 mph or higher) and 4-7 major hurricanes (Cats 3, 4, or 5 with winds of 111 mph or higher). The sea-surface temperatures are already exceeding last year’s temperatures. The figure above shows the differences in temperatures from this year and previous years. With all this in mind, NOAA is predicting an 85% above-normal season. The season stretches from June 1st – November 30th.

Monthly Weather Update!

The U.S. Seasonal Drought Outlook was recently released for the next three months. According to the update released on March 31st, drought will persist in West Texas and with some improvements in the Hill Country area. The precipitation forecast will not help as the next three months is forecasted to be lower than normal rain chances while the very East side of the State will receive higher than normal rain chances. In Texas, 45% of the State is abnormally dry or worse, this has increased 2% from last month.

Drought Conditions Persist and a Weather Update!

March 13, 2024 by casey.matzke

Over the last month the Eastern part of the State has received significant amounts of rainfall, while the Western part of the State is below average. Over the next three months, see figure adjacent, it is predicted that the Western part of the State, which is already dry, will be experiencing even drier than average conditions.

What does a strong La Niña this summer mean for Texas weather?

February 28, 2024 by casey.matzke

During this Winter season, parts of Texas have experienced a strong El Niño presence. However, El Niño has begun to weaken and is expected to do so over the next few months. El Niño’s counterpart, La Niña, is likely to take over as early as this summer. According to the Climate Prediction Center, there is a 55% chance of La Niña conditions by June 1st.

Monthly Drought and Weather Update!

In the past two months, East Texas and the Coast have seen more than two inches of rain. However, the Southern Coastal area and the Northeastern area of Texas have received more than four inches of rain. Far West Texas and the Panhandle have received less than .5 of an inch of rain, coinciding with most of the rest of the state that have received less than normal rainfall over the past thirty days.

The National Oceanic and Atmospheric Administration released its winter outlook. For Texas, we are looking at near-normal temperatures and wetter-than-normal conditions. While there are some potential drought improvements, it is expected to hang around. Figure 1b below gives us a three-month precipitation outlook.

Monthly Drought Update and El Niño Possibility!

October 11, 2023 by casey.matzke

The last three years have been years of La Niñas, while there is some chatter of a super El Niño coming, right now there is a 71 % chance of a strong El Niño developing (defined as a sea-surface temperature greater than or equal to 1.5 degrees Celsius). Figure 6a illustrates El Niño conditions exceeding 95% chance of extending through the winter, with growing chances of more neutral conditions in early Spring 2024.

Weak El Niño Now, But Likely to Grow Through Winter

July 26, 2023 by casey.matzke

Despite being weak, El Niño conditions continue to be in place, after the event was deemed officially underway a month ago. This is the first El Niño in four years and there is a 90% chance that these conditions will remain throughout winter.
