A line of storms with strong winds is moving through eastern and south-central Ohio with heavy rain and powerful winds. Pockets of damage have been reported with the stronger cells.
What to expect here in Ohio
Warmer air moved in ahead of a strong cold front that spawned severe storms late this afternoon that continued past nightfall in central Oho. A severe thunderstorm watch is in effect for central Ohio until 10 p.m., including the Columbus area.
The Storm Prediction Center has central and western half of Ohio under an enhanced risk for severe storms and the rest of the state under a slight to marginal threat. The greatest risk of damaging winds will occur between 7 p.m. and 9 p.m. in central Ohio.
The line of storms will move east of the region after 11 p.m., but windy conditions will linger into the night.
A wind advisory for gusts in excess of 50 mph continues until 11 p.m. for most of the area.
After the frontal passage, temperatures will start to plunge as another spoke of colder air swings down around the low on Friday, holding readings to the 40s.
More on the “bomb cyclone” outside Ohio
The powerful wind field with the latest storm system to cross the country is caused by deep low pressure and strong gradient, or difference in pressure that creates strong winds.
The storm was classified as a “bomb cyclone” because the pressure dropped of 24 millibars (.71 inch) (or more) in 24 hours or less.
The central pressure of the storm dipped from 29.35 inches (994 millibars) Tuesday evening to 28.60 inches (968 millibars) by Wednesday evening. New low-pressure records for intensity were reached in southeastern Colorado and western Kansas, and winds gusted to 80 mph at Denver and 97 mph at Colorado Springs in blizzard conditions.
NOAA Weather Prediction Center (WPC) meteorologist David Roth’s research listed a Kansas state record low barometer of 28.69 inches (971.6 millibars) on April 8, 1878, at Dodge City. The current storm may have broken that mark, pending further analysis.
Chillier weather will return in the wake of the storm, with much quieter conditions during the next 7-day period.
