The State Climate Office of Ohio (SCOO) had the honor of bestowing the first "Friends of SCOO" award to Humayun Ashraf. He volunteered his free time to assist the office's Mesonet team during the construction and maintenance of new weather stations while at Ohio State.

Strong fall weather systems commonly bring high winds to the U.S. If driving during windy conditions, slow down and keep two hands on the wheel, avoid large trucks and trailers, and watch for downed tree branches or other items in the road.

☀️ Drought Update: Drought conditions continue to tighten their grip on Northwest Ohio, while other regions of the state have seen some improvement. We will continue updating and sharing our resources as long as drought conditions persist.

A storm system will slowly continue to press across the central U.S. Friday and Saturday with widespread showers and thunderstorms. Slight risks for severe thunderstorms and excessive rainfall have been issued Saturday from the Ozarks into the mid-Mississippi River Valley with potential for damaging winds, large hail, tornadoes, and flash flooding. weather.gov

Ohio State helps farmers manage impacts as drought conditions spread across Ohio While not yet reaching the severity of last year’s growing season, drought conditions are once again taking hold across Ohio, raising renewed concern among agricultural experts and farmers about the health of crops, livestock and water resources.According to Aaron Wilson, state climatologist and f...

☀️ Drought Update—As noted in last week's update, this week's map reflects the precipitation that southern and eastern Ohio received Oct. 7.

Here's a more-detailed update from our state climate and weather expert, Aaron Wilson:

While the front (Oct. 7) produced cooler temperatures immediately following its passage, temperatures rebounded and overall were above normal this week (1-2°F above normal for October 8 – 15). Precipitation observations and impacts considered for this week’s update have brought widespread improvement to the southern and eastern counties, while drought conditions continue to intensify in northwest Ohio. This week’s U.S. Drought Monitor shows ~10% of the state is in D3-extreme drought conditions (a slight uptick over last week) while ~20% of the state is at D2 or worse. Overall, the total area of Ohio in drought (D1-D3) has reduced from ~73% to ~37%. As we move later into the fall, significant visual impacts to vegetation and crops are less apparent, though the drought is having an impact on fall color. Hydrology effects remain as well, (e.g., river flows, lakes, wells). Temperatures will trend warmer over the next couple of days (October 16-18), hitting the upper-70s to mid-80s on Saturday before another robust system brings showers, storms, and gusty winds to Ohio through Sunday. Current forecast totals would signal additional improvements in Ohio or at least a temporary halt to the drought’s expansion across northwest Ohio depending on totals and soil moisture recharge. Public reports of conditions are always welcome and can be made by visiting https://bit.ly/3KSHAl0. Our next update will be provided on October 23, 2025.
