Palmer Drought Index as of March 26, 2021
Rip Current Danger!!
Rip currents slide sideways along the beach. The red circle points to a person in danger. As the current swirls down the beach (blue arrow) the person goes from being in six inches of water to suddenly being in 3-4 feet of water that comes on him or her from an unexpected direction. Sometimes the current can be strong and disorienting. All of the sudden, the person is in a situation they cannot handle.
Most rips are more subtle but this photo -- and some bring water in from two directions -- but, this should give you the idea.
When there are rip current warnings out, be very, very careful you observe the pattern of the waves and flow before entering the water. Then, make sure you stay in shallow water.
A Way Forward For the National Weather Service
But, while weather modeling is vital, it is hardly the only serious issue with which the NWS is struggling.
- It's weather radars were designed in the 1980's and installed in the early to middle 1990's. While they have been upgraded several times, they will not last forever. There is no real plan for their replacement. The proposals to use phased-array radar will, when it comes to tornado detection, be a step backward due to its poor resolution.
- It has been evident for more than twenty years that gap-filler radars are needed, at least 20 in number. The NWS has done little or nothing to acquire and install them.
- The promised storm warning accuracy increases from various technologies (to cite one example, here) do not appear to have panned out. In fact, tornado warning accuracy has regressed and a new version has significant issues.
- The NWS has been dragging its feat on acquiring new types of data that are essential if we are to improve storm forecasting.
- Instead of fixing these issues and focusing on its core mission of storm warnings and forecasts, the NWS is 'reorganizing' itself to focus on decision support services, which -- in some cases -- is corporate welfare.
It is time to face facts: The National Oceanic and Atmospheric Administration, the parent agency of the National Weather Service, is failing in its management of public-sector weather in our nation. The NWS lacks a genuine vision for becoming the world's best public meteorological agency.
There seems to be no appetite in Washington to get to the root of the problem. The "ocean" side of NOAA and its constituency has far more clout than the atmosphere/weather side, even in this era of global warming concern. The first administrator of NOAA (1970-74) is the only administrator with a meteorological background in the half-century of the agency's history. The recent nominee of the Trump Administration failed because he had a weather background rather than one in fisheries or ocean enterprise.
Congress, in a rare bi-partisan manner, is more than willing to help but is not getting the guidance it needs from the agency and I doubt it will ever get that guidance because of the NWS being NOAA's figurative stepchild.
The current situation will never lead to the National Weather Service being first-in-class. So, I offer this unsolicited advice to both the Trump Administration and Congress.
The U.S. needs to do two things:
1. Split off the NWS from NOAA into an independent agency. It is time to concede NOAA, which was a good idea, needs a divorce.
2. As a Reagan conservative, I hate proposing more government. But, we desperately need a National Disaster Review Board (NDRB). Details of this proposal are here and here. The NLRB would also be tasked with verifying NWS forecasts and, especially, storm warnings. The people issuing the warnings should not be the people doing quality control evaluations.
There is a much better chance of the independent NWS striving to be best in class with the necessary tools (better models, gap-filler radars, etc.) and other essentials as an independent agency. If it does not, the NDRB will be holding its heat to the fire as the NTSB does with aviation and transportation.

A New Tornado Risk Forecasting Paradigm
Over the past two weeks there has been a lot of controversy within weather science pertaining to the risk categories used by the National Weather Service's Storm Prediction Center. It has even made CNN.
The problem centers around the words used to describe tornado risk and the colors used to portray these risks. The existing system was designed to be used by meteorologists, only. Now that these forecasts are widely used by the public, it is past time to revamp the descriptions of the standards.
I started using a new wording system on this blog and on Twitter in 2020 and have continued it in 2021. I propose it to my colleagues as a new industry standard.
- Significant Risk of a tornado is a 5% chance of a tornado of any intensity. In the above sample, it would be the yellow area.
- Enhanced Risk is a 10% chance. In the above, it would be orange.
- High Risk is a 15% or higher chance of a tornado and at least one of the tornadoes is expected to be rated F-2 or higher. The vast majority of tornado deaths are associated with tornadoes of F-2 or stronger intensity.
- Extreme Risk (rarely used) is a 30% chance of a tornado and at least one of the tornadoes is expected to be rated F-3 or higher. In addition to being dangerous to life and limb, mass destruction is possible.
* The percentages refer to the chance of a tornado within 25 mi. of any given point covered by the forecast. It is the industry standard.
In the event of a rapid-onset tornado threat requiring one of these forecasts after sunset local time, the meteorologist has the option to increase the threat one category if she/he believes it appropriate given the risk of deaths from overnight tornadoes is 2.5 times the risk from tornadoes that occur in daylight.
That's it. We'll talk about colors in the near future.

The Tennessee Tornadoes + Flooding = Lessons for All of Us
Lesson #1
From Channel 5 in Nashville,
There was so much weather to report, you might miss the item I have highlighted -- that two NOAA Weather Radio (NWR) stations were knocked off the air during all of the tornadoes and flash floods. That is why it is essential to have at least three sources of critical weather information. NWR is a great source of information, but it is vulnerable if the power fails or if the data feed from the NWS office to the transmitter is knocked out.![]() |

Newnan, Georgia, This Morning: An Incredible Tornado Warning System Success
- The reflectivity display (the type shown on television) showed a giant debris ball. That is a strong indication of a tornado.
- The Doppler wind data was extraordinary. It indicated rotational winds of around 160 mph -- a very violent tornado.
- The turbulence display shows the highly turbulent winds near the center of the tornado.
- Finally, a display known to meteorologists as "correlation coefficient" which displayed a huge area of lofted debris -- proof this was a major tornado tracking along the ground.
Hazardous Afternoon and Evening in the Mid-South
We have a flash flood forecast and an updated tornado forecast.
Tornado Risk
The tornado risk has been compressed into the yellow and brown areas.- Yellow area is where there is an enhanced risk of tornadoes. Where the yellow is hatched is where strong tornadoes are possible.
- Brown area is where there is a significant risk of tornadoes.
Tornadoes Likely Late Today and Tonight in the Mid-South
A Perfect Book For Spring
The next seven months are "storm season:" now for tornadoes and, starting May 15, for hurricanes.
Warnings: The True Story of How Science Tamed the Weather is very much a people story -- of courageous meteorologists who bet their careers to discover and implement the science needed to save thousands of lives every year.![]() |
From B&N |
Keeping in mind his audience, while this book could have been much longer, and more issues discussed could have been told with greater detail, Smith strikes a good balance of providing the necessary facts while holding the reader's attention. The sprinkling of human touches throughout the science makes the book intelligent and a bit emotional (but full disclosure: I am emotional at all tornado stories!).
Smith has a huge arsenal of weather events to describe, and he chooses carefully. Some tornadoes are those that affected him personally, but some events, particularly the hurricanes, are life-changing events in the history of storm prediction. In particular, his account of the numerous failings around Hurricane Katrina, committed by everyone except the meteorologists, is well done. Obviously, he cannot get into the many layers of problems before, during, and after Katrina, but his job is not to address all of those. He simply has a few chapters to discuss the science and remind the reader that the best science in the world can't overcome horrible bureaucracy.
The book ends beautifully by demonstrating how far we've come with forecasting and the ability to save lives, the foundation of all forecasting work. Smith chooses the ferocious Greensburg tornado to show how the advances in science have saved many lives. While the 1999 Bridge Creek-Moore tornado was perhaps even more of a celebration when comparing population to death toll, Smith makes good use of the facts around Greensburg to perfectly compare it to the earlier, much deadlier, yet otherwise very similar Udall tornado.
Smith has a lot to say in this area, and he says it well.
Whether you want a "storm season book" or just a great book for spring vacation, if you like this blog, you'll really enjoy Warnings.
You can get your copy of Warnings at Barnes & Noble, Amazon and your local bookseller. If you enjoy reading this blog, you'll love Warnings.

Yesterday and This Morning's Tornadoes: Rotation Paths
The brighter the colors, the stronger the rotation.
The map shows remarkably long-tracked tornadoes. Pending the completion of the damage survey, the Birmingham NWS office believes that one of the tornadoes may have been on the ground at least 100 miles. This is what we meant when we forecasted "violent, long-tracked tornadoes." Those are important because they are usually the type that cause the most deaths.
The tracks show that Birmingham (B) was struck both north and south of downtown. The suburbs southwest of Atlanta were also struck after midnight -- an extremely dangerous situation given that nighttime tornadoes cause 2.5 times more deaths than tornadoes during the day.
I am providing this extra coverage because the national media seems to have already lessened its coverage because of the lack of deaths; even though that is a very good thing!
If you have a chance, please contribute to legitimate charities (not the Red Cross which is poor for tornadoes) like the Salvation Army to help the victims recover more quickly.
A Politician Who "Gets It" About the Lack of Deaths in Violent Tornadoes
Yesterday's Tornado Outbreak and What It Means to Us
Yesterday was an extraordinary success story for American weather science: numerous, violent, long-track tornadoes in densely populated areas yet a minuscule number of fatalities.
While each of those deaths is a tragedy for their families and friends, without weather science it is likely there would be a hundred funerals being planned rather than seven. That is especially true since several of the violent tornadoes occurred in darkness. The forecasts and warnings made all of the difference.
I was awakened by the sirens and sheltered in my hallway. I was sheltered when the tornado hit.
-- Newnan, Georgia, resident
Unfortunately, the mainstream media still doesn't get it. It wasn't "luck" that triggered those phones after midnight -- it was the finely-tuned tornado warning system.
There are several aspects of yesterday's storms I wish to discuss with you.
Safety Recommendations Reviewed
The Weather Channel aired the above photo and it illustrates one of our safety recommendations: Take shelter in the basement or lowest floor. Generally speaking, the lower -- the better.Global Warming Nonsense
- If tornado patterns were changing because of global warming, they would be shifting to the north, not south.
- The great Dr. Ted Fujita in 1975 demonstrated that tornado alley shifts in a more or less cyclical pattern. These shifts are independent of world temperatures.
- Violent tornadoes, like yesterday's, have become less frequent in a warmer climate.
Meteorologists' Homes Being Hit
On Wednesday, ABC TV meteorologist Ginger Zee posed with her mentor, Birmingham's legendary James Spann, in his trademark "respect the polygon" pose. The were trying to build awareness that major tornadoes were going to occur the following day (yesterday).

Tornado Forecast Update - 2:45pm
Considerable serious damage has already occurred in northern Alabama.
Here are the tornado warnings (red) as of 2:45pm.
"Particularly Dangerous Situation" Tornado Watch Until 8pm
Please monitor the weather throughout these regions until at least 8pm.
Extreme Risk of Tornadoes This Afternoon and Evening
- There is an extreme risk of tornadoes in the purple area as shown on the NWS's forecast.
- There is a high risk of tornadoes in the red region. Violent tornadoes may occur here, as well.
- There is an enhanced risk of tornadoes in the orange area. Strong tornadoes may occur in this region.
- Finally, there is a significant risk of tornadoes in the yellow-colored region.
A tornado watch means you should monitor the weather in your area and be prepared to take shelter at the first sign of a thunderstorm.
Please particular attention to a tornado watch that contains the sentence, "This is a particularly dangerous situation." One or more of those rare watches may be issued Thursday or Thursday evening.
When a tornado watch is issued:
- Call family and friends to make sure they are aware of the threat and insure they are going to monitor the weather at the first sign of thunderstorms. This means the sound of thunder or darkening skies.
- Make sure you have a flashlight in your shelter area along with a couple of bottles of water, a radio/TV/weather radio, diapers, and a snack of the kids (something like trail mix). If you have bicycle, football or other head protection in the house, put them in the shelter area.
- Gather up the family of those who may need help getting to shelter. You don't want to be darting through traffic to pick up children while the sirens are sounding. Way too dangerous.
- Insure your safety first! Get you and your family into shelter. Only then call friends and relatives to make sure they have gotten the warning.
- Stay in the shelter until you are given an all clear or until five minutes after the radar shows nothing over your location.
- Do not go outdoors to try to look for the tornado. Tornadoes are often invisible. Both of the locations below were struck by the Joplin Tornado but it could not be seen during its approach.
Do you see the tornado in these pictures? The only thing you are doing by doing outside to look is putting your life in danger.

Overnight Tornado Watch in Texas
Please make sure you have a weather radio set to go off for a tornado warning in your area plus an smartphone app like AccuWeather's that will trigger if a warning is issued for your location.
I will have an update on tomorrow's weather situation in an hour or so.
High Risk of Tornadoes in the South Thursday and Thursday Evening
Here we go again:
- The red area has a high risk of tornadoes. Some of which could be violent.
- The orange area has an enhanced risk of tornadoes, some of which could be violent.
- The yellow areas have a significant risk of tornadoes.
The highest risk period is from noon until midnight. I don't think this tornado outbreak will continue into the overnight hours.
I'm more concerned about the risk of violent tornadoes tomorrow than I was with the weather situation like week. It is quite possible we will be talking tomorrow about a rare "extreme" risk of tornadoes. Unlike last week, tomorrow's risk extends well north into Tennessee.
No is the time to prepare. Please do so.
Significant Tornado Risk in East Texas
There is a major risk of tornadoes in the South tomorrow. I'll have an update on that by around 1pm.

Global Warming: Is There Anything It Can't Do?
From the Wichita Eagle:
This is a preposterous story written by a reporter "embedded" with the Eagle to write global warming scare stories.Let's deal with the contention that Wichita is third worst. Here is the money quote
In other words, this isn't even about pollen or air pollution. As usual, it is a MSM scare story about a warmer climate.
The longer growing season is one of the best aspects of a warmer climate and it has been essential to feeding a hungry world.
