Ontario campers beware: Severe storm, tornado risk builds Saturday
Heat warnings are in place for much of southern Ontario as the hot and humid weather settles in this weekend. This instability will fuel a risk for strong to severe storms—including the risk for one or two tornadoes.
Make sure you keep an eye on the radar—especially if you have outdoor plans—and stay aware of any severe weather watches or warnings issued in your area.
DON'T MISS:
Parts of northwestern Ontario already received a helping of thunderous weather early Saturday morning, but we'll see the risk of thunderstorms continue to shift southeast throughout the day as the low-pressure system treks across the province.
Strong thunderstorms are expected to develop in the early to mid-afternoon hours and continue through the evening across northeastern Ontario, moving southeast into cottage country. A warm front and upper-level trough will increase the risk for severe storms to develop.
While the storm risk extends across much of southern Ontario, the greatest risk for severe weather will fall along the shores of Lake Huron and Georgian Bay, extending north toward the Greater Sudbury Area and North Bay. There is also an isolated risk of one or two tornadoes in these areas on Saturday. The storms will form into a line and continue moving east across parts of central Ontario.
Forecasters are also looking at the risk of rotating storms developing around the Parry Sound area and through a chunk of cottage country.

The greatest risk with Saturday's strongest storms will be hail 2+ cm in diameter, strong wind gusts of 90+ km/h, and heavy downpours that could produce 30-50 mm of rainfall.
Many people are at cottages and camping in this region. Falling trees and lightning strikes are both deadly hazards.
RELATED:
If you are in the region, please stay on top of severe weather alerts and know what to do and where to go in the event severe weather approaches. If you know anyone in northeastern Ontario or cottage country this weekend, please ensure they're aware of Saturday's severe weather threat.
A risk for thunderstorms will redevelop on Sunday as a cold front pushes into an unstable atmosphere across the Greater Toronto Area and into eastern Ontario, including Kingston and Ottawa, and into southern Quebec. We could once again see some of Sunday's storms turn severe.

July 2025 sets record for fourth wettest July in Detroit history
This may not come as much of a surprise after the torrential rainfall this week, but July 2025 is ending in the top five wettest Julys in Detroit. Flash flooding on Wednesday, July 31, brought us over the line, but not before we experienced heavy rainfall on Monday, July 28. Detroit reached 7.38 inches of rainfall for the month. The month's average is 3.51 inches of rainfall. There is no doubt we've seen an abundance of water this month, but reaching the top tive for the fourth wettest ranking is a feat. Records for the Detroit area go back to November 1874.

Flash Floods Swamping Roads In The Northeast And Mid-Atlantic As Severe Thunderstorms Drop Heavy Rain
As blistering heat gives way to thunderstorms in the Northeast and mid-Atlantic, dangerous flash floods are swamping roads and trapping drivers in some parts of Maryland, Pennsylvania and New York. Heavy rain is expected to persist along the I-95 corridor throughout the afternoon and the evening commute, with the potential for more than 2 inches of rain per hour. Here's the latest on the impacts of the torrential rain. (MORE: See The Full Forecast) Maryland Multiple water rescues were reported in Joppatowne, Maryland, about 40 minutes outside of Baltimore early Thursday afternoon. Photos on social media showed washed out streets, and officials have asked drivers not to attempt to drive through standing water. Emergency officials in Harford said northern parts of the county got 3 inches of rain in 30 minutes. Baltimore City Schools dismissed their summer programs at 2 p.m. Thursday due to the flooding threat. By around 5 p.m. local time the rain was coming down at 3 to 5 inches an hour in the Baltimore area. A ground stop was issued at Baltimore-Washington International Airport due to the storms, until at least 6 p.m. Pennsylvania In Reading, Pennsylvania, cars were seen stranded in rushing floodwaters Thursday afternoon. Flash flood warnings were in effect in parts of Berks, Bucks, Montogmery and Lehigh counties. New Jersey In New Jersey, acting Governor Tahesha Way declared a State of Emergency ahead of the potential flash flooding across that state. Her announcement warned of as much as 7 inches of rain in some areas, along with damaging wind gusts. By early Thursday afternoon, there were reports of flooding shutting down parts of highway US 22 in both directions in North Plainfield. New York In Queens, New York, vehicles were seen submerged along the Clearview Expressway. New York Police said the expressway was "fully closed" in both directions at North Boulevard. Heading into rush hour, significant portions of the borough were impassable due to flooding. Governor Kathy Hochul declared a State of Emergency for New York City, and the surrounding counties. Gov. Hochul encouraged employers to dismiss workers early since the flooding was expected to impact the evening commute. The Long Island Railroad announced on X that service was suspended in both directions on the Port Washington Branch line due to high water. Video shared on social media showed floodwaters pouring over a stairway at a station in Great Neck, New York. The Metropolitan Transit Authority also warned subway and bus riders to give themselves extra time for their commutes because of the heavy rain. This is a developing story.

In Rare Spasm of Sanity, Pentagon Backtracks on Plan to Scuttle Storm Tracking
In a stunning reversal, the Pentagon said it will uphold a longstanding program that supplies critical hurricane data to federal forecasters—just days before it was set to end. The move follows outcry from meteorologists and public officials blindsided by the planned cancellation at the start of hurricane season. In June, the Navy's Fleet Numerical Meteorology and Oceanography Center (FNMOC) announced it was shutting down the Defense Meteorological Satellite Program by Thursday, July 31. DMSP weather satellites are owned by the Department of Defense (DoD) and have provided storm data to the National Oceanic and Atmospheric Administration (NOAA) since the 1960s. The announcement sparked outrage among weather officials preparing for an active hurricane season, which had only just begun. Then, on Wednesday, July 30, the Navy told ABC News that it will keep the program going for another year. 'After feedback from government partners, officials found a way to meet modernization goals while keeping the data flowing until the sensor fails or the program formally ends in September 2026,' the Navy stated. NOAA confirmed the change in a statement emailed to Politico: 'There will be no interruption to DMSP data delivery and NOAA will continue to have access to data from DMSP for the duration of the Program's life span.' Many storm trackers are likely breathing a sigh of relief. Although NOAA has publicly maintained that cancelling the DMSP would not impact the quality of hurricane forecasting, scientists inside and outside of the U.S. government told The Guardian it would be a significant loss. 'Before these types of satellites were present, there would often be situations where you'd wake up in the morning and have a big surprise about what the hurricane looked like,' Allison Wing, a hurricane researcher at Florida State University whose work depends on the program, told the publication in June. 'Given increases in hurricane intensity and increasing prevalence towards rapid intensification in recent years, it's not a good time to have less information.' DMSP weather satellites are designed to support military operations, but meteorologists have used their data for general weather prediction and storm tracking for more than 50 years. Equipped with a powerful instrument called the Special Sensor Microwave Image Sounder, or SSMIS, these satellites capture microwave imagery of hurricanes—essentially 3D X-rays. This allows forecasters to see the interior structures of storms. This information is incredibly valuable. Being able to observe a hurricane's eye and eyewall—a ring of tall thunderstorms that surrounds the eye and produces heavy rains and strong winds—tells meteorologists whether the storm is strengthening or weakening. That means they can catch major changes like rapid intensification hours before other tracking technologies detect them. Rapid intensification can be deadly—it drastically reduces the time available for communities to prepare and evacuate. Spotting it early can significantly reduce the number of injuries and fatalities. The Pentagon's decision marks a rare win for extreme weather preparedness under President Donald Trump. Over the last seven months, the administration has gutted NOAA's staff, proposed major cuts to its funding, and significantly reduced its research and data-sharing capabilities. This has unfolded against a backdrop of increasingly aggressive attacks on U.S. climate policy, which will undoubtedly worsen extreme weather. For now, at least, forecasters get to keep one of their sharpest tools.
