Weather Update: Ample July Precipitation for Most

Summary

The precipitation pendulum has swung back the other direction for many across the state in July. Figure 1 shows that much of western and central Ohio have picked up more than 150% of normal precipitation, with multiple rounds of showers and storms. CoCoRaHS observations for the month show rainfall totals in the 8–10-inch range for Delaware, Licking, and Franklin Counties in central Ohio. This wet pattern has been accompanied by temperatures running near average for most of Ohio, and 1-3°F above average for counties in the southwest and northeast.

Forecast

A front that dropped south of the region on Monday, will edge back northward near the Ohio river on Tuesday and meander there through Thursday. Multiple disturbances will ride eastward along this front, bringing numerous rounds of showers and storms across the state. Most of the activity will be focused south of about I-70, though northern Ohio will not be rainfree. Temperatures will be kept in check, with highs in the 70s expected on Tuesday, and upper 70s to low 80s on Wednesday and Thursday. Dry, tranquil weather will return for Friday through the weekend, with low humidity and mild temperatures. The Weather Prediction Center is forecasting 1.0-3.0 inches of rain for southern counties, tapering to less than 0.5 inch across the north, primarily over the next 3 days (Figure 2).
