Cold and very dry air is in place over the region and will lead to another unseasonably cold night tonight. In fact, with skies remaining clear and winds gradually diminishing through the night, it’s likely that some places will find themselves in the 10s first thing tomorrow morning – with a thick frost likely to accompany the mid-winter cold.
Fortunately, the core of this arctic air mass is already shifting seaward and there is milder air lurking off to our west. While a full-blown warm-up isn’t really in the cards, temperatures will at least return to more seasonable levels as we move through Friday and kick off the weekend.
The Thursday late afternoon visible satellite image and temperature map below shows advancing clouds over the Great Lakes and Ohio Valley – which are indicative of a warm front lifting north and eastward. Along and behind that frontal zone, noticeably milder air is lifting northward as a return flow of air becomes established.
This milder southwest flow is poised to (at least somewhat) shift into our area over the next 24 hours.
