If you live in the affected areas, please stay tuned to your local National Weather Service office for the most accurate and up-to-date information.Our active pattern continues as a classic stretch of severe weather setups take aim at the Plains starting today. Enhanced Risks (level 3/5) have been outlined by the SPC for the next four days, with each day posing a risk for significant severe hazards, including strong tornadoes and very large hail.Today, widespread convection is expected across southern Oklahoma and north Texas, with a more conditional risk along the warm front from central into northwest Oklahoma. Large to very large hail and damaging winds will be the main risks, but a couple tornadoes are possible, especially if any storms fire near the warm front and via any favorable storm interactions.Tomorrow, discrete supercells are expected ahead of a robust dryline from Nebraska into Texas, with the greatest risk centered on Kansas into northern Oklahoma. All hazards are possible, including strong tornadoes and large to very large hail.Stronger forcing for ascent will overspread the dryline on Monday, leading to a higher-ceiling but lower-floor event. Once again, intense supercells are possible with all hazards, but storm mode remains a question. The threat shifts east into the Mid-South/Southeast on Tuesday.------------------------------------------------------------------------Want to learn how to forecast and chase severe storms from the best meteorologists and storm chasers in the business?

The April 2, 2025, Tornado Outbreak: Behind the High Risk with SPCs Chris Broyles Convective Chronicles 2025-05-14 | On April 2, 2025, a tornado outbreak occurred from the Midwest to the Mid-Mississippi Valley. The night before, Storm Prediction Center forecaster Chris Broyles made the decision to upgrade to High Risk, which, at the time, was quite surprising to many in the meteorological community. When all was said and done, the High Risk verified well, with multiple EF3+ tornadoes in and around the High Risk area.In this video, I sit down with Chris to discuss his thought process in the days leading up to his High Risk issuance. He goes through, in detail, what he was seeing in model data regarding the forecast synoptic environment, along with several of the in-house SPC tools that he used to make his High Risk forecast. We also discuss this setup in the context of his OMEGA Project research, including an analysis of the 500 mb jet.Thumbnail image from Luke Robbins (X: @LukeRobbinsWX).---------------------------------------------------------Chapters:0:00 Introduction3:07 OMEGA Project background8:33 Comparison of tools for High/Moderate Risk discrimination12:30 Meteorological analysis for April 2 event - Day 321:10 Meteorological analysis for April 2 event - Day 229:01 Meteorological analysis for April 2 event - Day 152:23 Discussion of High Risk placement55:13 Discussion of right entrance region of jet57:49 High Risk outlook verification1:00:33 Final comments---------------------------------------------------------Want to learn how to forecast and chase severe storms from the best meteorologists and storm chasers in the business?

If you live in the affected areas, please stay tuned to your local National Weather Service office for the most accurate and up-to-date information.UPDATE - SPC has upgraded to Moderate Risk (level 4/5) ahead of an intense bowing segment currently moving through Arkansas (as of 11:45am CDT). Greater confidence in strong tornadoes and significant damaging winds in excess of 80 mph has necessitated the upgrade.Another day of significant severe weather potential is on tap today from east Texas to western Tennessee today, where SPC has outlined an Enhanced Risk (level 3/5). Most of the convection is expected to be messy/linear in organization, but any more discrete supercells in the open warm sector may pose a risk of strong tornadoes and very large hail. Damaging winds and tornadoes are also expected within the main line along the cold front. Excessive rainfall and catastrophic flash flooding is also expected to continue across the Mid-South today.------------------------------------------------------------------------Become a Patreon member today to support the channel: patreon.com/convectivechroniclesFacebook: facebook.com/ConvectiveChroniclesX: twitter.com/ConvChroniclesInstagram: instagram.com/convectivechronicles------------------------------------------------------------------------Looking for a reliable way to get up-to-the-minute severe weather alerts from me wherever you are?

If you live in the affected areas, please stay tuned to your local National Weather Service office for the most accurate and up-to-date information.On the heels of yesterday's significant severe weather outbreak from the Midwest to the Southeast, more is on the way, particularly from the Southern Plains into the Mid-South and Southeast. Today (Thursday, April 3), SPC has outlined an Enhanced Risk (level 3/5) from the ArkLaTex into Tennessee, where ample convection is expected to develop near and north of a stalled frontal zone. Most storms should remain elevated, posing a large to very large hail risk, but any storms can latch onto the front or impinge upon the warm sector will pose a risk for all hazards, including strong tornadoes.Tomorrow, an Enhanced Risk has also been outlined from the ArkLaTex into southeast Oklahoma, Arkansas, and far southern Missouri. A better chance for more surface-based supercells exists here given a northward advancing, broad warm sector, and all hazards, including strong tornadoes, are once again possible.Saturday, another significant severe weather episode is expected, focused on east Texas, Louisiana, southern Arkansas, and western Mississippi, where a Day 3 Enhanced Risk has been outlined. All hazards are possible, including strong tornadoes.Excessive rainfall and catastrophic flash flooding is also expected across the Mid-South along the slow-moving frontal zone, where multiple rounds of convection are forecast to train over the same areas through the next three days.------------------------------------------------------------------------Become a Patreon member today to support the channel: patreon.com/convectivechroniclesFacebook: facebook.com/ConvectiveChroniclesX: twitter.com/ConvChroniclesInstagram: instagram.com/convectivechronicles------------------------------------------------------------------------Looking for a reliable way to get up-to-the-minute severe weather alerts from me wherever you are?

The Tri-State Tornado: A Meteorological Breakdown Convective Chronicles 2025-03-19 | In-depth discussion of the infamous Tri-State Tornado of March 18, 1925, which remains the deadliest tornado in US history. The tornado tore an apparent 217-mile-long path through Missouri, Illinois, and Indiana, killing at least 695 people, injuring at least 2,000, and wiping towns from the face of the Earth. In this video, we'll attempt to reconstruct the meteorology behind such a tornadic monster, including what the background pattern looked like and how such a long-track, violent tornado was able to occur. We'll also try to piece together what the tornado may have looked like and whether or not it was truly a single, continuous tornado for its entire path.---------------------------------------------------------Become a Patreon member today to support the channel: patreon.com/convectivechroniclesFacebook: facebook.com/ConvectiveChroniclesX: twitter.com/ConvChroniclesInstagram: instagram.com/convectivechronicles---------------------------------------------------------Chapters:0:00 Introduction0:59 Overview of the tornado4:26 Meteorological analysis12:59 Tornado's visual appearance14:59 Was it one tornado or a tornado family?17:16 Wrap-up---------------------------------------------------------Resources:Maddox et al.

The May 25-26, 2024, Tornado Outbreak: A Meteorological Breakdown Convective Chronicles 2025-02-19 | In-depth meteorological breakdown of the tornado outbreak that occurred across Plains and Mid-South on May 25 and 26, 2024. On May 25, the SPC had outlined a level 4 out of 5 Moderate Risk, including a threat for significant, long-track tornadoes across southern Kansas and Oklahoma. However, things didn't quite go to plan until nightfall, when separate cyclic supercells produced multiple strong tornadoes, including EF3s near Valley View, TX; Claremore, OK; and Decatur, AR. On May 26, the outbreak continued, with multiple discrete supercells producing strong tornadoes from the Ozarks eastward. In this video, we take a deep dive into the meteorology behind this setup, including what issues plagued the daytime environment on the 25th, why the nighttime supercells on the 25th were able to go nuts, and how the outbreak evolved on the 26th to continue the outbreak.Thumbnail image from Andy Shriner.Huge thanks to:-Mikey Williams for providing his analysis on the southern Kansas supercell of May 25.-wxKobold (on X) for providing the storm-centered radar loops of the Valley View and Claremore/Decatur supercells.-Alex Bartholomew, Andy Shriner, Mason McCormack, Connor Stines, Joshua and Emily Leach (J&E Wx Chasers), and Drew (X: @Wx_Beans) for providing their photos and videos.Contents0:00 Introduction0:54 May 25 analysis begins2:01 Meteorological analysis - May 258:00 Discussion of left splits - May 2511:12 Southern Kansas supercell discussion - May 2525:47 Valley View, TX, supercell discussion - May 2531:16 Claremore, OK/Decatur, AR supercell discussion - May 2535:20 May 26 analysis41:23 Wrap-upBecome a Patreon member today to support the channel: patreon.com/convectivechroniclesFacebook: facebook.com/ConvectiveChroniclesX: twitter.com/ConvChroniclesInstagram: instagram.com/convectivechronicles----------------------------------------ResourcesNWS Norman event page: weather.gov/oun/events-20240525NWS Paducah event page: weather.gov/pah/May26_2024SevereNWS St. Louis event page: weather.gov/lsx/5_26_2024My May 20, 2013 breakdown: youtube.com/watch?v=N1RXY7Lf43sNixon et al.

Adequate instability and strong low-level/deep-layer shear will overspread a broad warm sector, setting the stage for severe storms mostly in the form of a squall line along a surging cold front. Damaging winds and a few tornadoes, some of which may be strong, are possible with the QLCS. The threat for prefrontal supercells is low given a lack of forcing over the warm sector for much of the day; this could increase tonight across southern portions of the risk area. Any discrete supercells that are able to develop and sustain before the QLCS marches in will pose a risk for strong tornadoes and damaging winds.Become a Patreon member today to support the channel: patreon.com/convectivechroniclesFacebook: facebook.com/ConvectiveChroniclesX: twitter.com/ConvChroniclesInstagram: instagram.com/convectivechroniclesChapters0:00 Introduction, risk areas2:54 Observed data analysis17:15 Model analysis31:29 Convection allowing model (CAM) analysis36:45 Wrap-up

Breaking Down the Oklahoma Storm Chasing Bill...Does It Ban Chasing? Convective Chronicles 2025-02-05 | In recent days, the Oklahoma legislature has brought forth a bill that would attempt to regulate storm chasing in Oklahoma. There has been a lot of confusion within the storm chasing community on what this bill entails, who it targets, and whether or not it will ban recreational storm chasing in Oklahoma. In this video, we go through the entire bill page by page to the best of my understanding to get to the bottom of its purpose and clear up the confusion.Link to the bill: legiscan.com/OK/text/HB2426/2025Become a Patreon member today to support the channel: patreon.com/convectivechroniclesFacebook: facebook.com/ConvectiveChroniclesX: twitter.com/ConvChroniclesInstagram: instagram.com/convectivechronicles

If you live in the affected areas, please stay tuned to your local National Weather Service office for the most accurate and up-to-date information.A regional severe weather outbreak is expected tomorrow (Saturday, December 28) across the Gulf Coast states, where SPC has outlined an Enhanced Risk (level 3/5). A potent shortwave trough and surface low will act upon a broad warm sector, within which multiple rounds of storms are forecast, beginning early Saturday morning. Weak capping and strong forcing will likely lead to widespread convective coverage, meaning more a messy storm mode, but all severe hazards are still possible, including the threat for tornadoes, some strong, especially in more discrete supercells. The threat will persist into the eastern US on Sunday.Become a Patreon member today to support the channel: patreon.com/convectivechroniclesFacebook: facebook.com/ConvectiveChroniclesX: twitter.com/ConvChroniclesInstagram: instagram.com/convectivechroniclesContents0:00 Introduction, risk areas2:36 Current state of the atmosphere6:59 Model analysis38:11 Brief discussion on Sunday's threat39:58 Quick note on Nadocast42:14 Wrap-up

If you live in the affected areas, please stay tuned to your local National Weather Service office for the most accurate and up-to-date information.***This was recorded before the SPC upgraded to Enhanced Risk across southeast Texas, but the forecast logic I discuss in the video remains valid.***Severe weather returns to the forecast today for parts of east Texas, western Louisiana, and southern Arkansas. SPC has outlined an Enhanced Risk (level 3/5) where the greatest risk for tornadoes, some strong, exists, surrounded by a large Slight Risk (level 2/5). Ahead of a compact but potent trough, rich moisture will make its way northward into these areas, setting the stage for thunderstorm development. Several factors look to preclude a more intense event, but ample severe storms with all hazards, including tornadoes, are possible this afternoon into evening. The threat will persist into the morning tomorrow.We'll also briefly discuss our next robust severe threat, set to take place on Saturday in and around the Gulf Coast States. SPC has outline a Slight Risk for this event, as well, and it could be more potent than today's event.Become a Patreon member today to support the channel: patreon.com/convectivechroniclesFacebook: facebook.com/ConvectiveChroniclesX: twitter.com/ConvChroniclesInstagram: instagram.com/convectivechroniclesContents0:00 Introduction, risk areas3:51 Observed data analysis21:26 Model analysis34:35 Convection-allowing model analysis38:39 Brief discussion of Saturday's setup45:13 Wrap-up
The May 21, 2024, Iowa Tornado Outbreak: A Meteorological Breakdown Convective Chronicles 2024-12-23 | In-depth meteorological breakdown of the severe weather outbreak centered on southwest Iowa on May 21, 2024, which included the Carbon, IA EF3 and Greenfield, IA EF4. Fast-moving storms, including supercells, developed in southeast Nebraska and southwest Iowa during the early afternoon on May 21, eventually moving east into an environment favorable for significant severe weather. In this video, we'll take a deep dive into the background meteorology that fueled this event before discussing the incredibly unique convective evolution that took place leading up to and during the Greenfield EF4. We’ll also analyze some high-resolution, mobile radar data of the Greenfield tornado, which packed winds of over 300 mph.***Sorry for the audio issue from 16:20-16:41. Here's what I'm supposed to be saying during that time: "To start the day at 12z, we see a profile comprised of modest instability and steep lapse rates elevated atop fairly limited low-level thermodynamics. Low-level shear was already strong, with ample hodograph curvature and effective storm-relative helicity nearing 250 m2/s2, in part due to easterly surface winds near or perhaps just north of the synoptic warm front."----------------------------------------Thumbnail image from Isaac Polanski (via NWS Des Moines) and Chris Riske.

The May 6, 2024, Oklahoma High Risk: A Meteorological Breakdown Convective Chronicles 2024-12-02 | In-depth meteorological breakdown of the severe weather outbreak that occurred across the Plains, particularly Oklahoma, on May 6, 2024. SPC had outlined a level 5 of 5 High Risk for severe weather on May 6 with the expectation that discrete supercells would be able to produce several long-track, strong to violent tornadoes. However, things did not go as planned, as the daytime round of supercells failed to produce significant tornadoes and eventually grew upscale into a squall line. But, all it took was one storm...a supercell fired ahead of the QLCS and produced the beastly Barnsdall, OK, EF4 after dark. In this video, we'll take a deep dive into the meteorology behind this event, focusing on some of the possible reasons why the daytime activity tended to underperform. After that, we'll discuss how the Barnsdall supercell and tornado developed, as well as some of the unique features they possessed.Thumbnail image from Teddy Galligher (X: @GalligherTeddy).
