More on what to expect Friday in a moment but first, mild tonight, cloudy with lows in the upper 50s. Thursday will be even warmer with temperatures climbing into the upper 60s all thanks to a strong southerly wind. Take the umbrella along tomorrow scattered showers are expected out ahead of the cold front. That rain continues across the area through Thursday night into early Friday. Here’s the latest Futurecast depiction for that period.

Early Friday rain will turn to a rain/snow mix before changing to snow during the day. Futurecast shows the latest timing. Travel conditions will deteriorate as the day goes on.

Before the changeover to snow there could be some freezing rain and sleet, this means some icing is possible first mainly west of Nashville. About 1/4″ in most spots.

    Some seriously crazy temperature swings. Today’s high reached 66, the warmest it’s been since December 23, when the temps maxed out at 69 (in and of itself a remarkable occurrence, since the temperature spiked by more than 10 degrees well past midnight, while in the daytime it was more seasonable). In between, we hadn’t even seen a single day in the 50’s. 18 days of sub-50 temps is nowhere near the record of 43, from January-February, 1979, yet it’s the longest such streak since January 2011, which had a 19-day run. Given how incredibly warm last two years were, our recent cold spell felt even colder.
    December wrap-up and a look back at 2017.
    December was the coldest month of its name since 2010, which doesn’t mean a whole lot, as the previous six Decembers were all mild to extremely warm (2015). It averaged out at 40.3 degrees, just 0.1 degrees below the norm, which is within the margin of error, so it was pretty much a normal December, overall. There were two pronounced alternating warm and cold spells and the month started out quite warm, while the final week or so was the most consistently cold stretch of weather of the entire year. It easily became the coldest month of 2017, by virtue of having practically no competition, since January and, in particular February, were exceptionally mild. Precipitation of 4.56″ was somewhat above average, and most of it fell from 17th through 23rd, the second warm spell. Only a trace of snow was recorded, on Christmas Eve.
    2017 was, expectedly, one of the warmest years on record for Nashville, in fact, tying 2007 and 1921 for the second-warmest.

    Warmest years in Nashville

    1. 2016 62.8

    2. 2017 62.5
    2007
    1921

    3. 2012 62.3

    4. 1990 62.1

    5. 1998 61.9

    As can be seen, our top 5 is comprised of fairly recent years, four of those being from the last decade. Last year got off to such a furious start, that after four months, including the hottest ever April, it was already evident, that it was bound, at least, for the top 10. The only noticeably cooler month was August. Precipitation-wise, at 52.92″, last year was 32nd-wettest, doesn’t sound terribly impressive, bit it was still considerably above average, compared to 143 years in the book. Only January, February and May were on the drier side, the rest having either adequate or excessive precipitation (April and, especially, August). Snowfall was quite low, only 1.9″ was measured on just two dates, January 6 and March 11 (0.4 and 1.5 inches, respectively), while February was entirely snowless. Hopefully, this winter season will provide a refreshing break from persistent, unseasonable warmth, as has already been witnessed.
