Very dry air near the ground Thursday. Dew points are running close to ten degrees! This is almost unheard of in March, more like the desert southwest, says Chief Meteorologist Jamie Simpson. In fact our dew point is lower than Phoenix this afternoon. Our relative humidity is about 20%. That’s why we’ve just seen fairly high clouds today, the only moisture is tens of thousands of feet above our heads. Why is this important? Because a weak cold front with some showers head our way from the Upper Midwest Friday, and will have little impact due to our dry air. The result will be about as much cloudiness as we see Thursday. The front may not even make it all the way o the southern Miami Valley, likely stalling just north of I-70.
Cooler air will work into the northern part of our area where highs may only be in the 40s Friday. Dayton, Springfield, and points south of I-70 will have no trouble making it into the 50s again.
Saturday, the front lifts well to the north and warmer air arrives. When warmer air arrives, however, it sometimes rings clouds. I expect that will be the case to start the day Saturday with more sun in the afternoon. We’ll start the next two days in the 30s but rise to the low 60s Saturday afternoon.
That starts a string of 60+ degree days that may last all the way through the workweek next week. However, they will be cloudier days with rain at times as a front stalls out just north of us and disturbances ripple along it. If the front can lift north a few hundred miles on day next week and we stay dry with more sun we might reach 70.
There are some hints that may occur Tuesday or Wednesday.
