Light snow moves into Ohio today with a minor disturbance moving quickly over the region. Action today look to stay rather localized. Scattered snow showers push into west-central Ohio near midday, and then continue to spread east as they slide south through the afternoon and evening. Everything should be done by Midnight tonight. Generally, we are expecting snow to be mostly limited to central and southern Ohio, about 75 miles either side of I-70. In terms of amounts, we are looking for a coating to an inch from in most areas. We won’t rule out a few flurries north of US 30 and a dusting in spots, but generally this is a central and southern Ohio event. The map at right shows potential for today.
We kick off a dry forecast pattern on Friday. We should stay precipitation free over almost all of the state from Friday through next Wednesday night. We do have a significant storm complex exiting the central plains Saturday and moving across the Deep south. AT this point we are keeping all precipitation from that system south of the Ohio river into KY. We wont rule out a few clouds in far southern Ohio this Sunday and perhaps early Monday, but that is it. The rest of us see a nice mix of sun and clouds. This will be the longest dry stretch we will have seen in quite some time.
Light snow moves back into the region next Thursday, bringing a coating to 2 inches to 70% of the state. A second wave of action hits on Friday as a strong low starts to pass to the south, but then hooks north into western PA. That means we see a significant increase in snow threat next Friday over eastern OH. We can see an additional coating to 2 inches in western OH, but in eastern areas, snow Friday through early Saturday can be significantly higher, with the highest coming near the lake. In addition, winds do look to be a problem. We can expect 20-40 mph winds statewide on Friday coming out of the north on the backside that a powerful low. If winds stay at our projected intensity, we would see blizzard conditions over eastern Ohio, and potentially even some nastiness in western Ohio. This event looks nasty right now…but has plenty of time to modify and put in a different track…so stay tuned.
For the extended period, we continue to see an active 6 day stretch. Rains arrive on the 17th and linger into early the 18th, bringing .1”-.5” totals, mostly over the southern half of the state. Then as have another frontal complex arriving for the 20th. This one has rain potential of .25”-.75” with 80% coverage of the state south of US 30. Notice we continue to talk rain! While the nearby 10 window looks cold, particularly with a reinforcing shot of cold air this weekend, the 11-16 day period warms considerably, and we expect well above normal temps all the way through the 22nd. This will allow all precipitation in that extended forecast to stay liquid. This cold, dry stretch looks to us to be the best opportunity to finish up the late harvest and may be the best chance of the rest of 2018.
