Unusually windy June pattern


The wind was relentless at times this weekend out of the east, not a common direction in the late spring and summer months in Ohio.

The wind gusted at times up to 25 mph, making it feel a little cooler than the near-80 degree temperatures.

The reason for the gustiness was a pressure difference between a Canadian high pressure area drifting across northern New England and a meandering low over the western Tennessee Valley.

Pressure difference between a high over New England and low pressure in the Tennessee Valley caused a steady east-southeast wind all weekend uncharacteristic of June.

The downslope wind blowing across the northern Appalachians had a drying influence on Ohio, because air was and loses humidity, undercutting a tropical plume of moisture streaming north from the Gulf of Mexico.

Spring is normally the windiest time of year in Ohio, but that is normally what happens in March and April, associated with vertical temperatures differences (cold up top, warm at the bottom).

Daytime heating instigates updrafts and subsequent downdrafts that mix gusty winds down to the surface. An unusually strong jet stream blowing southwest to northeast in late spring has accounted for additional strong wind fields in the lower and middle atmosphere.
