Why central Ohio is seeing fewer tornadoes in 2025 than a year ago
COLUMBUS (WCMH) — After an active early spring, no tornadoes were reported in Ohio during May, which has only happened seven times in the past 30 years.
The drop-off was related to a southward shift of the jet stream, with storms focused across the southern half of the country. Severe storms capable of producing a tornado require heat and moisture (fuel), in addition to a strong jet stream in the vicinity. Columbus had a 16-day stretch of below-normal temperatures in late May through June 2.
All but four of the tornadoes in Ohio this year have been relatively weak EF0 events, and only one touched down in central Ohio–an EF0 tornado (85 mph winds) near Obetz that tracked 2.6 miles on the night of March 30.
Last year, a record 74 tornadoes were confirmed in Ohio, including 23 storms in May. After five tornadoes touched down on June 5, 2024, in eastern Ohio, the 1992 record for a single year (62) was already equaled. The average number of tornadoes in an entire year in the Buckeye State is 22.
Multiple tornado outbreaks impacted central Ohio in 2024, beginning on Feb. 28 and continuing through the spring, before a summer drought curtailed the storm threat. The calendar year was the warmest on record in Ohio, and in Columbus (57.3 degrees), with city records back to 1879.
May averages more tornadoes than any other month in Ohio and the U.S., because of the frequent clash of cool, dry Canadian air and summerlike heat and humidity drawn northward by southerly winds from the Gulf. The other essential ingredient for rotating storms is wind shear — winds shifting direction with height — which causes the air to spin within strong updrafts.
Nationally, 328 tornadoes were reported in May, fewer than in April (358), and comparable to a very active March (300), based on preliminary reports from the Storm Prediction Center in Norman, Okla.
Through the end of May, Missouri and Illinois recorded 105 tornadoes, second only to Texas (109). A total of 1,042 preliminary unfiltered tornado reports were logged as of May 31 in the U.S., with final assessments often taking many months to complete, to remove duplicates of the same event.

Canadian wildfires prompt another air quality alert for coastal Maine
Jun. 9—The Maine Department of Environmental Protection says smoke from Canadian wildfires is again impacting air quality in Maine. Ground-level pollution concentrations in southwest coastal Maine were in the "unhealthy for sensitive groups" level Sunday and have continued in that range into Monday. The elevated level is most likely to impact children, older adults, and people with respiratory or heart disease. While the pollution concentration level may drop during the day Monday, another plume of wildfire smoke is expected to move in from the east and reach the Maine and New Hampshire coast by afternoon, according to the DEP. That plume from the western Canadian wildfires broke off over Newfoundland and Labrador and has now moved south into Nova Scotia. The smoke is expected to move move out Tuesday, but it could return in the coming days as wildfires continue to burn across Canada, the DEP said. The air quality could cause people with asthma, bronchitis, chronic obstructive pulmonary disease or other conditions to experience reduced lung function and irritation, according to the DEP. Officials say it is possible that even healthy adults who exert themselves outside could notice side effects, such as coughing, shortness of breath, throat irritation and mild chest pain. People can protect themselves by avoiding strenuous outdoor activity, closing windows, and circulating indoor air with a fan or air conditioner. Last week, smoke from the Canadian wildfires led the DEP to issue a similar air quality alert for much of Maine's coastline Wednesday and Thursday. Dozens of wildfires burning in the western provinces of Manitoba and Saskatchewan, including one more than twice the size of Los Angeles, have forced thousands of Canadians to evacuate their homes in recent weeks.

Tracking a dry start to the work week
Happy Monday St. Joseph! A northwesterly flow is carrying patch smoke from the Canadian wildfires, leading to hazy skies that will gradually clear by the afternoon. The same northwesterly winds contributing to the haze will also keep temperatures cooler. Highs today will be below average, with temperatures topping out in the mid-70s. Tonight, skies will stay clear and overnight lows will be cool once again as temperatures will drop into the mid 50s. Tomorrow, southwesterly winds will return, bringing warmer temperatures. Sunshine will stick around, and afternoon highs are expected to reach the mid-80s, making for a more summerlike day. Dry air will also be present, making conditions pleasant. On Wednesday, it will stay dry, but it will be hot and humid, with temperatures climbing into the upper 80s to low 90s. Starting Thursday and continuing through late week, rain chances will return.
