Ohio Ag Weather and Forecast — March 20, 2018

Some slight changes to the outlook this morning, as moisture seems to be bent on drifting a bit farther north. We still do not see anything working north of I-70 this morning, but we have to allow for a better spread of moisture from I-70 southward. Rain this morning will try to end as snow early this afternoon, particularly from central Ohio east toward the PA line. NW Ohio sees nothing today, and most of north central Ohio is devoid of precipitation as well. However, northeast Ohio can pick up some light snow later this afternoon.

Cold air stays over the state behind this system for tomorrow through early Friday morning. Wrap around cloud cover and moisture will be in overnight tonight through tomorrow and likely brings accumulating snow to a large part of the state. Accumulations of a coating to 3 or 4” are likely with 80% coverage through tomorrow. The map above is one model depiction of snow…and it is likely over done on the 5-6-7 and 8 inch snow totals…but it does show a good geographical coverage of snow here. This map also puts the snow way too far to the west too…but you get the idea: from tonight through tomorrow, it is not going to act like spring at all anywhere in Ohio. Snow ends tomorrow night as the nor’easter for the east coast moves north and away. It stays cold through Thursday, and temps moderate some by Friday as south winds arrive ahead of the next front.

That system moves in for Saturday midday through Sunday morning. Latest models are shifting the heavier precipitation farther south out of this event. Right now we will keep rain totals of .25”-5” the southern half of the state, but are ready to give the northern half a pass for the time being. In the south, we have to be prepared to see the precipitation end as wet snow again, with minor accumulations.

Dry for Monday of next week, but we have another system coming in for overnight Monday night through Tuesday. This event can bring .25”-.75” precipitation to 70% of the state, with the heaviest action seen over central and southwest Ohio. The map above shows a snapshot of early Monday morning. Then we take a minor break with dry weather Tuesday night and Wednesday, followed by another batch of scattered showers for Thursday, adding another .25” over 60% of the state.

Moderate to heavy rains arrive for Easter weekend on the 31st and 1st. We are raising rain totals to .5”- 2” over 100% of the state. This will be a very moisture laden system. But then we go dry for the 2nd through the 5th for the remainder of the extended forecast window.

The rest of the extended window has a system for Easter weekend on the 31st and 1st, bringing .25”-75” rain potential to about 70% of the state. However, temps look to stay normal to slightly above normal for the entire extended period.
