Ohio Ag Weather and Forecast — November 21, 2017

Dry today with strong southwest winds developing over the state. Winds are expected to reach 15-30 mph at times through the day. But, the southwest flow will allow temps to moderate further, and we should see temps today above normal.

A cold front moves through this evening through the overnight tonight. We still think the precipitation threat is very low, but clouds look to be persistent. That, combined with the big change in air mass is prompting us to keep a few sprinkles or light snow flakes in over the state overnight into tomorrow morning. The best threat of action will be in north central and northeast OH, where we can see some light snow, but we won’t rule a little precipitation out anywhere. The key word is “little”…as available moisture looks to be limited to a few hundredths to at most .1”. So, anything that happens will be rather inconsequential. Still, the bigger story will probably be the dramatic fall off in temps again, with tomorrow and Thanksgiving Day ending up below normal. Winds will likely be strong out of the northwest tomorrow. The map above shows temps as they compare to normal for Thanksgiving afternoon.

No change in the rest of the forecast. The roller coaster decides to go back up hill from late Thursday night through the rest of the week and weekend. Temperatures climb for Friday with strong southwest winds returning to the region. We should see above normal highs for Friday and Saturday statewide. Again, we go through these temp changes with no precipitation.

Our Sunday disturbance is coming a little faster, and may be in on Saturday afternoon. At this time, it appears to be a strong low that passes well to our north, over Michigan and into southern Ontario. This may drag some clouds down into northern Ohio Saturday into Sunday, but we are keeping the region mostly free of precipitation. You might see a spit or sprinkle north of US 30, but even that does not look overly impressive. Colder air does wrap around the backside of the low and cool us back down to below normal levels for late Sunday afternoon and the start of next

The next good threat of precipitation develops at midweek next week. On Wednesday, the 29th, we see nice moisture moving in from the west. However, models are less enthusiastic about this system this morning than they were 24 hours ago. We are leaving our forecast alone at this time, but may have to revise it lower if we see any other consensus building For now, we will look for.2”-.6” of moisture over 80% of the state. This front should move through relatively quickly.
