LIMA — With a warmer than normal summer and and plenty of precipitation throughout the year, 2018 felt like a year missing a fall and spring.
Taking a look at 2018 in total, Accuweather senior meteorologist Dave Bowers said the year’s average annual temperature was just 8 percent higher than its normal, leading to a warm summer and a winter lacking normal snowfall.
“For the year, it’s pretty close to normal. About a degree and a half above normal when you’re talking about a 12-month period,” Bowers said.
A month-to-month analysis, however, shows some interesting turns as the year played out.
The region’s normal temperature curve tends to be more gradual, with steadily increasing temperatures peaking by July before decreasing gradually throughout fall months. 2018, however, avoided the gradual curve with a dry cold spring, warmer than normal summer and a fall that switched from record-breaking overnight highs to premature colder weather, Bowers said.
According to National Weather Service observed temperatures, the year started out mostly colder than average up until May, when temperatures jumped significantly.
Normal temperatures recorded by the National Weather Service average a 10-degree difference separating April and May. The same monthly averages in 2018 saw a 25-degree jump between the two months.
Besides a few cold spells, the warmer weather stayed until mid-October and then seemed to switch overnight leading into colder-than-normal temperatures by November.
Due to the mid-month switch, October ended up averaging a temperature close to its normal average, but the month broke records throughout northern Ohio in its second week with some of the highest minimum temperatures ever recorded by the National Weather Service in those areas on those days.
By the time November hit, however, winter was firmly in the wings. Cold temperatures had replaced the warmer weather sooner than expected, which even ended up affecting City of Lima services, notably the city’s asphalting and leaf pick-up programs.
As for precipitation, the year was wetter on average, Bowers said. Outlier months this year were August, which saw 7.77 inches compared to its normal 3.64 inches due to a slow-moving pressure system, and February, which doubled its normal rainfall and added 2 inches to its normal amount of snowfall, leading to some flooding in the region.
As for its effects, February’s rains played a part in the collapse of a large sewer line in Lima, creating a major sinkhole on Grand Avenue that required extensive repairs before the street could be reopened.
The National Weather Service’s December monthly report has yet to be released. Its latest data for northwest Ohio and northern Indiana characterized 52 of 2018’s days as fair, 135 as partly cloudy and 147 as cloudy.
