Weather Update: Seasonal Rollercoaster


Accumulated Precipitation (in)Summary

After the warmest October on record (1895-present), a flurry of frosty of mornings have officially brought the 2021 growing season to a close. Many areas have experienced low temperatures in the low to mid 20s, with the coldest temperature of 19°F occurring near DeGraff in Logan County on November 5. Precipitation has varied widely across the state, with the heaviest occurring across Ottawa County and south-central Ohio (Figure 1). Wet conditions there have continue to hamper harvest and manure activities. Outside of these areas, precipitation has been a bit below average. We have also seen our first reports of snowfall across northeast Ohio. For more climate information, check out the State Climate Office of Ohio

Precipitation ForecastForecast

High pressure will remain anchored southeast of the region over the next couple of days. A weak cold front could bring a few widely scattered showers across the northwest counties Tuesday night. After another dry day on Wednesday, a much stronger cold front will approach the region on Thursday, bringing widespread rain showers and gusty winds. High temperatures will reach the 60s across Ohio for Tuesday through Thursday, 50s on Friday, then upper 30s to mid 40s over the upcoming weekend. There could be a few rain and/or snow showers across the north this weekend as well. The Weather Prediction Center is currently predicting 0.25-0.50” of precipitation over the next 7 days, with slightly greater amounts for the far northeast and southeast portions of the state (Figure 2).
