Ohio Ag Weather and Forecast — July 10, 2018

No change in the near-term forecast through the rest of this week, but this morning we are keeping an eye on a couple of new wrinkles for the weekend, and next week. These wrinkles are hinting at some better precipitation chances and totals, but we are not changing our forecast just yet. As always, we are looking for a couple more data points to confirm the need to change, so stay tuned.

Today looks very similar to yesterday, meaning we are dry in nearly every part of the state. There may be some heat-based instability and cloud cover in west central or southwest Ohio that can trigger a very isolated shower or two, but it is not enough to really be concerned about at all…just pay attention in those areas this afternoon. Dry weather holds tomorrow through Friday, and temps remain warm. Highs today through Friday to be in the mid to upper 80s statewide,  with a few places making a run at 90. Those temperature ranges are generally 2-5 degrees above normal. Humidity values will stay low today and tomorrow but may start to build later this week. The map at right shows rain potential through Friday.

For the weekend, we are keeping our forecast dry. But, this is where wrinkle number 1 comes in. We have a disturbance moving over the great lakes for the weekend. Some models are trying to sweep a little moisture out of this system farther south into northern Indiana through the day Saturday, and late in the day into NW Ohio. . It’s not so much that the track is changing, but more that these models are trying to project a less compact circulation. If moisture were to develop, it would likely stay north of US 30, meaning at least 2/3 of the state sees nothing anyway. The best chances would be later Saturday and Saturday night.  But to be clear, we are not putting more moisture in our forecast at this time, but this will be a feature we look closely at the next two days. Sunday is dry, but humid in our forecast, and that pattern holds into Monday.

Our next threat of moisture is still on track to develop Monday night through Wednesday morning. Moisture remains in a .25″-1″ range for the day and a half to 2 day period, coverage around 70%. However, this is where we encounter wrinkle number 2. Models are suggesting we see another surge of moisture and energy Wednesday that lasts into Thursday. This surge would not only bring more rain but could ultimately lead to a strong thunderstorm outbreak statewide on Thursday. While this is at the end of the 10-day window, it would make sense, given the building of warm air over the region up to that point. If our cold front strengthens, thunderstorms would be a potential offshoot. Much like our discussion of wrinkle number one, we are not changing the forecast right now, but giving a heads up as to some potential future moves, if data starts to swing toward this solution. For now, we have rain leaving Wednesday by mid-morning, and sunshine back for Thursday. But, we will update you tomorrow morning.

In the 11-16 day window, we move on with more of a basically dry forecast pattern. Strong surface high pressure settles in over the eastern corn belt and controls the flow through at least the 22nd. There is a front looking to sag into the state around the 23rd and 24th, near the end of the extended period. As we alluded to yesterday, if that front holds together, it has potential to bring half to 1” of rain. But, confidence remains low at this point.

February 20, 2019 -- Our mess is here this morning. We are going to zero in on the “easy” part of this first…and that is that by midday, all precipitation is rain, and it will be moderate to heavy. We expect at least .25” -1.25” of rain after precipitation changes over today, and that will cover 100% of the state. Now, for the hard part. The freezing line this morning is still in central Ohio...
