So What Happened?

Current Official Hourly Observation (taken at :53 on the hour) & Radar

TodayCloudy and Chilly – High 38

We should be above freezing by mid-morning.

We made it to, then below, freezing overnight, but only for a few hours.  What happened?

It didn’t snow because the precip was falling through a large layer of above-freezing air (illustrated by last night’s weather balloon data, see below), which didn’t have time to freeze by the time it made it to the ground. By the time the warm temps overhead cooled below freezing, the precip was gone (by the way, this has been the theme of our snow chances this winter).

It didn’t ice because (1) temps weren’t below freezing long enough, (2) the ground was still pretty warm from Saturday, running around 3 to 5 degrees warmer than the air temps, and (3) temps didn’t drop far enough below freezing.

Areas to our north and west (as close as Dickson) saw some ice. There may be a few slick spots here, especially on bridges, overpasses, and at elevation, but the overwhelming majority of local reports are of clear driving conditions.

Looking Ahead
