Oklahoma is bracing for a dangerous combination of high winds and critical fire weather. State Climatologist Gary McManus is warning of a “bomb cyclone” moving into the region. The term, while sounding dramatic, accurately describes the rapidly intensifying weather system poised to impact the state.
Understanding the “Bomb Cyclone”:
McManus explained the phenomenon, stating, “So we have what some are calling a ‘bomb cyclone’ moving into Kansas tomorrow. A bomb cyclone is a surface low pressure system that has undergone ‘bombogenesis.'” He then clarified the technical term, “In other words, a bomb cyclone (or bombogenesis) is a term used to describe an explosively intensifying low-pressure system.”
To put it simply, McManus said, “This surface low up in Kansas will generate wind gusts of 50-70+ mph in Oklahoma tomorrow, which will combine with low relative humidity and high temperatures in the 70s and 80s to produce critical fire weather.”
Critical Fire Weather and “Firestorm” Potential:
The resulting fire danger is severe. “Critical fire weather?” McManus asked rhetorically, then answered, “That’s correct.” He quoted the Oklahoma Department of Agriculture, Food & Forestry’s “Fire Situation Report,” which warned of “a statewide threat for High Significant Wildfire potential.”
The report went further, stating, “Furthermore, conditions on Friday continue to trend toward Wildfire Outbreak and a Firestorm cannot be ruled out.” A firestorm is a very intense and destructive fire that creates and sustains its own wind system, characterized by strong, turbulent winds and often accompanied by tornado-like whirls, making it extremely difficult to control.
The fire situation is exacerbated by the current drought conditions. “Our current drought situation doesn’t help matters,” McManus noted, though he clarified, “It’s not the most critical factor–most of the vegetation out there is still dormant… but it can impact those longer-term fuels in the soils or on the ground.” McManus noted we don’t see any rain in the forecast for a bit.
Regional Weather Contrasts:
McManus also highlighted the stark contrast in weather conditions across the region. “Don’t feel too jealous about that rain to our east. That looks like it will have a 2-day tornado outbreak along with the moisture,” he said. “Not that our next 2 days are gonna be much better, of course, but even wildfires and blowing dust in 75 mph winds are better than what they’ll get over that way.”
Preparing for the Dangerous Conditions:
McManus emphasized the need for immediate preparation, urging, “Time to prepare, as well as for the fire danger expected today (and through the next week).” Residents are advised to:
- Be aware of the extremely high fire danger and avoid any outdoor burning.
- Secure loose objects that could be carried by high winds.
- Stay informed about weather updates and warnings.
- Have a plan in place in case of wildfire.
The combination of high winds, dry conditions, and potential for rapid fire spread makes this a particularly dangerous period for Oklahoma.
