Freezing, then cool
It’s a cold morning out there! The official temperature for Dayton dropped down to 28 degrees this morning… we haven’t been in the 20s since mid-March! So it’s the coldest we’ve been in about a month… amazing. A FREEZE WARNING continues through 9am. At that time, it will be safe to uncover the plants, and bring the potted plants out to get some sunshine. But don’t wash the sheets just yet! We have another FREEZE WARNING tonight into early Thursday morning. Again, we’ll drop into the upper 20s/low 30s.
High pressure building south out of Canada is to blame for the colder readings. This morning, the high is still northwest of us, and we have a pretty good breeze… which is helping prevent a widespread frost. BUT the high will settle right over us by Thursday morning, so the threat of frost will be greater with lighter winds:
The high then will provide mostly sunny skies Thursday afternoon, and slightly warmer temperatures. We’ll climb back into the upper 50s–which is still below normal, but warmer than we have been! As the highs continues to head east, our winds become more southerly, and that means even warmer readings for Friday and the weekend. Mid 60s and dry on Friday… with 70s for Saturday and Sunday… but also a good chance of rain. Parts of the region could see some good soaking rain out of this event through Tuesday of next week. The exact placement of the heaviest rain is still in question, but this run of the GFS could give you an idea:
That has parts of the Miami Valley over an inch. We’ll continue to watch the trends and keep you posted!
