We are watching our cold front move off to the east this morning, and watching a big transition over the Eastern Corn Belt. A dramatic change in temperatures is afoot with Mother Nature finally breaking out of her identity crisis and admitting it is autumn after all Temperatures today will be a good 15 degrees cooler (at least) than yesterday and nearly 20-25 degrees cooler than some of our warmest temperature readings over the weekend. We will also soon be done with rain here as the front exits eastern ohio and should see sunshine take control later this afternoon ahead of sunset. Tomorrow will be mostly dry too, at least through the daytime hours.
A minor batch of moisture moves across the state tomorrow night into early Saturday morning. We expect no more than .25” of action over 70% of the state. Moisture totals are unchanged from yesterday, but we are expanding our coverage a little bit. Everything is still done by mid morning Saturday, and we have a dry rest of the weekend on the way.
Moisture returns Monday afternoon and ramps up for the evening and overnight hours. We will put rain totals at .1” to .5” with coverage at 80% of the state. These rains break out statewide, and should be relatively gentle, but steady once they start. Rain will be basically over by sunrise Tuesday, although we may end up dealing with a few lingering showers in far eastern Ohio and southeast parts of the state.
Dry weather then settles in for the rest of the 10-day window, and it extends through most of the extended 11-16 day period too. We are tweaking the forecast just a bit this morning and are projecting a 10-day dry stretch starting next Tuesday and going through the following Thursday. Clouds may pop up from time to time, but we do not see any significant frontal boundaries or systems crossing the state. This period should see good evaporation and good drying, meaning we should have an excellent harvest window opening up.
Rain is back in the forecast for Friday the 26th. We are expecting .25”-.75” rains with coverage at 75% of the state.
Temps are much cooler today as we noted above. However, after the Sunday night-Monday system, we make another leg down in temps, and will see our coldest air in here next Tuesday morning with good hard frost potential. The map at right shows potential morning lows next Tuesday. There can also be some patchy frost this weekend, particularly in northern parts of the state, although it will not be even close to a killing frost. The rest of next week and the extended period will feature temps normal to slightly below normal across the region, meaning our Indian summer is gone, and fall is here.
