Weekend Weather Review:
What an interesting weekend of weather across northern Ohio. Showers and thunderstorms on Saturday and Sunday left plenty of damage in their wake and thousands without power. A number of trees were toppled and golf ball sized hail was reported in the Akron area.
As we've said in past blog postings, our main severe weather season is April through June, but severe storms can literally occur any time during the year given the right weather setup as warm air battles cold air.
Here are some related stories to the weekend storms you might want to check out.
Sunday was the first day during August we hit 90 degrees at Hopkins Airport. We've now had a total of 13 days of high temperatures above 90, or one less day than by this time in 2018.
Here's a look at our weekend highs and lows across northern Ohio including...
Cleveland: 87/69 (Sat), 91/68 (Sun)
Akron/Canton: 86/68 (Sat), 91/70 (Sun)
Mansfield: 84/67 (Sat), 92/66 (Sun)
Youngstown: 86/62 (Sat), 90/67 (Sun)
Toledo: 86/69 (Sat), 83/67 (Sun)
Monday Evening Weather Update:
The storms are gone for now, but are likely to return on Tuesday as we get set for a major cool down. The National Storms Prediction Center has placed Ohio under a "marginal" risk for severe thunderstorms tomorrow.
The interesting thing about this outlook is the rarer "Enhanced" risk area for much of Illinois and southern Indiana. That area is likely to see some large tornadoes on Tuesday and into Tuesday night.
On the latest weather map according to the National Weather Service in Cleveland, a weak area of high pressure over the area will move east of the region overnight.
A stationary front south of the area will lift back north across the area as warm front Tuesday morning. A cold front will move southeast across the local area Wednesday evening.
A ridge of high pressure will build southeast across the area Thursday. High pressure will be centered over the local area Friday night.
Weather 101: Estimating Hail Sizes
Since hail was a part of our weekend weather, let's take a look at how you can estimate the size of hail based on some common items.
Hail is a type of precipitation that occurs when thunderstorm winds, known as updrafts, carry drops of rain into the sky and into very cold areas of the atmosphere where they freeze into balls of ice and fall back to earth.
Most hail storms are made up of a variety of hail sizes. They can range from pea-size that can hurt if they hit you, but aren't dangerous, to life threatening hail the size of baseballs or teacups.
We don't really know how fast hailstones fall, but forecasters have calculated estimates of their speeds in excess of 100 mph. If a hailstone the size of baseball hits you falling at that speed, the stone can kill you and do serious property damage.The poor guy below had his car trashed by baseball-size hailstones in the Dallas area where larger hailstones are more common than in northern Ohio.
Below is a graph I put together that helps you estimate hail sizes by comparing it to common items you can remember. Pea-sized hail is about a quarter inch in diameter, while a quarter is one inch and a tennis ball is about two and half inches in diameter.
So next time hail falls at your house, try to measure its size and if it's big enough, please report it to the National Weather Service immediately. Just remember, your safety first!
