![]() He says there was a brief spell of hot and humid weather when heat indices in the Chicago area peaked in the 105-115 degree range, while O’Hare airport recorded high temperatures of 98 degrees on the 14th and 96 degrees on the 15th, the latter of which set a new daily record for June 15th.Ībout a week later, a renewed bout of hot and humid weather returned with both O’Hare and Midway airports recording their warmest temperatures of the year of 99 and 101 degrees, respectively, on the 21st. “But there were still a few periods of notable warmth, mainly during the month of June.” “This summer as a whole certainly wasn’t quite as warm as the past two summers, which finished among the top 10 warmest summers on record in Chicago (summer 2020 remains the warmest summer on record with an average temperature of 76.7 degrees, while summer 2021 was the eighth warmest on record with an average temperature of 75.3 degrees),” Rafal Ogorek, a meteorologist at the National Weather Service ‘s Chicago office, wrote in an email to the Tribune. And though the century mark was not reached at O’Hare International Airport, the city’s official recording site, the metro area experienced some of its highest temperatures in a decade in June. The first day of astronomical summer brought the heat. These were the most extreme days in Chicago weather this year, with insights by meteorologists in the National Weather Service’s Chicago office and Trent Ford, Illinois state climatologist. Winter, spring, summer and fall each had something special to share. 22 wasn’t the most significant day of the year for weather watchers. It's definitely something to watch, but there's no cause for alarm right now.įor more on this story, follow Elyse Smith on Facebook, Twitter and Instagram.Rain appeared overnight in the city, but quickly changed into thunderstorms with hail, then covered the ground in freezing rain before turning into snow, according to the National Weather Service. Plus, it's also the time of year we monitor the Bay of Campeche for any areas of low pressure that could develop and become something tropical. If so, the rising motion of Central America and options of the Caribbean could aid any tropical development if it were to happen. However, long-range climate models are also hinting that the MJO could enter a different phase in early October. But constant wind shear from the jet stream will likely keep things quiet across the Gulf regardless for the rest of the month. While this wouldn't limit activity entirely across the Atlantic, it could keep the tropics quiet in the Gulf of Mexico and the Caribbean. The MJO is hinting that an area of sinking motion, currently located over the eastern Pacific and limiting tropical development there, could move over Central America and to the Caribbean and portions of the deep tropics in late September. Now, there are some signs that tropical activity in the Atlantic could slow down over the next few weeks but not go away entirely. This is also reflective of a typical El Niño season, with storms developing further west off the coast of Africa and staying east of the Caribbean and Gulf of Mexico. Most of the activity has been in the central/eastern Atlantic, with several of those storms taking similar paths through the middle of the ocean. The result: eight tropical storms developing in the Atlantic, with two locally in the Gulf of Mexico. Throughout the month of September, an area of rising motion has been over the Atlantic Ocean, which aided in tropical development. RELATED: NOAA forecasters now predict above-average hurricane season for 2023 As it does, it can influence local weather patterns, especially in the tropics, through areas of rising or sinking motion. To recap, the MJO is a wave pattern that expands across the entire globe and slowly moves from west to east. ![]() ABC13 Meteorologist Elyse Smith previously reported on this, noting the influence of the Madden Julien Oscillation (MJO). 18.įor the past three weeks, there was a noticeable increase in activity in the Atlantic after a quiet stretch that lasted from late July to late August. And with a little over two months left in the season, here's a broad overview of what the rest of this hurricane season could look like as of Sept. This makes for an above-average and active season, as we typically don't reach that number of named storms until November. So far, there have been 14 named storms this season, with the latest storm Nigel strengthening into a hurricane Monday. 10, but that doesn't necessarily coincide with less activity to come. The Atlantic Hurricane Season reached its climatological peak on Sept. ABC13 Meteorologist Elyse Smith looks ahead at what to expect for the rest of the hurricane season after the tropics have been active lately.
